Chapter Text



The party is in full swing by the time Liam shows up. It's just a small gathering with all of his friends, but there's a part of him that knows Theo is going to end up showing up too. Really, it's the downside of Hayden being friends with Theo’s not-girlfriend. He finds everyone in the living room and plops himself down on the couch. Mason hands him a beer and the cool liquid feels like a cool, temporary balm for his already irritated nerves. Liam easily falls into the conversation happening, pushing any thoughts of Theo to the back of his mind.

Hayden shows up a while later, dragging Tracy behind her. Theo comes in behind him and Liam feels his irritation climbing again. It's like everywhere he goes, Theo’s there. And he knows that's partially because they both still live with their parents and partially because their girlfriends are best friends. Theo looks over at him, giving him that infuriating smirk that makes Liam want to slam his fist into his stepbrother’s face. He downs the rest of his beer as he grabs another. He’s got a pleasant buzz going but he knows it isn't nearly enough for him to be willing to tolerate his sarcastic stepbrother. It’s not that he hates Theo, far from it in fact. No, he’s been harboring a secret obsession for his older stepbrother. But he knows that he can’t act on it, can’t do anything about it because he needs to play the part of the perfect son. He’s already caused his mom enough hardship by looking too much like his father, having the same temper as him too. This is something that he has to do for her, has to be the perfect son so he doesn’t disappoint his mother.

Hayden sits next to him, practically gluing herself to his side. Theo sits on the opposite end of the couch and Liam wishes he had chosen literally any other seat in Scott’s living room. She rests her hand on his thigh and it takes everything in Liam to not flinch away from her touch. It's not that he doesn't like her - actually that's not true. He doesn't like Hayden. At least not as his girlfriend. Her touch revolts him and she’s been pressing for them to have sex again. Which in the beginning of their relationship was fine. It was great, actually. But now it feels like a chore. He has to force himself to get hard, force himself through the motions of fucking her. Hayden hasn't done anything wrong, she was loyal and gorgeous, but something between them had died. At least, on Liam’s part of things. Mason keeps telling him that he should break up with her if he’s feeling this way, but he can't bring himself to do it. Not after the way his mom had looked so happy when he’d brought Hayden over and introduced her as his girlfriend. Now though, he feels like he’s stuck with her. Mason throws him a sympathetic look as Hayden’s hand slowly inches higher up his thigh. He smacks his hand down over hers, squeezing it before pushing it back down to his knees. Hayden pouts at him for a moment before Tracy hands her a drink.

The party continues on later into the night, everyone getting pleasantly buzzed. Stiles suddenly has the great idea to have them play a game.

“Come on guys, it'll be fun. We can wear the masks we used for Halloween.” It takes a bit of convincing but everyone ends up agreeing. Scott and Stiles gleefully rush off to find the masks. Hayden leans in closer, her lips brushing against his ear. Liam's skin crawls and it takes everything to not pull away from her.

“Let's sneak off and go have sex.” He shakes his head.

“No, they'll be back soon.” Hayden leans back into her seat, pouting as she sips her beer. Liam looks to the other end of the couch, but Theo and Tracy are gone. He looks around but doesn't see them anywhere in the living room. Scott and Stiles come back a few minutes later, clutching the two boxes they'd throw the different masks into after Halloween. Tracy comes back into the room after them; her hair is mused and her mouth is swollen. Theo comes in behind her, smirking as he sits on the couch again. Scott splits everyone up into even teams of twelve, saying he’ll be the judge to make sure everyone sticks to the rules. He passed out the mask, black for the chasers and white for the runners. Tracy looks put out about being put on the chaser side, but Hayden gives her an encouraging smile before glancing over at Liam. He knows she's expecting him to chase after her, but honestly he doesn't have the energy for that tonight. He wants to drive his fists into something, or someone. Preferably Theo if he can get his hands on him. His mom will be disappointed in him when she sees the state he’ll leave his stepbrother in, but he can't really be arsed about. Theo has been taunting him for weeks with his words and that goddamn smirk he’s always wearing.

“Remember, don't kill each other. Or seriously maim anyone. Runners get a two minute headstart.”. Theo’s team put their masks on and pull the hoods of their hoodies up over their heads before running out into the woods. Hayden glances back at him, winking before fully pulling her mask down and following the others. Josh rolls his neck as he watches Nolan run.

“I'm gonna fuck Nolan when I catch him.” Scott elbows him in the side.

“No, the rules…” He starts before someone cuts him off.

“Nuh-uh, you didn't say anything about not being able to fuck them.” Scott lets out a heavy sigh before looking at his phone. He knows that there’s really nothing he can do to stop the others.

“Go.” He says and the chasers take off. It doesn't take very long before Liam hears someone screaming, but he ignores it as he runs farther. Usually running helps him, but tonight it isn't enough. Tonight he needs to ruin someone with his hands. He sees someone run behind a tree and he runs faster to catch them. Liam tackles the other person, pinning them face first down on the ground. They struggle against him, but he plants a hand on the back of their head and presses their face into the dirt. The mysterious person struggles harder against him, rubbing their ass against his hard dick as they try to squirm away. Liam looks down, confused with his body’s reaction since he hasn't been able to get hard without forcing himself for months. He shakes his head before taking stock of the person beneath him. It isn't Hayden, she'd been kicking and screaming until she realized it was Liam. Then she’d be tearing her own clothes off and trying to convince him to fuck her right here on the forest floor. No, this person is broad and tall, their body firm underneath him. They've finally stopped fighting against him, panting into the ground as they lay still. He slowly eased himself off of them before pulling them up onto their knees. He keeps a harsh hand on their shoulder as he walks around to stand in front of them. A blank white mask stares up at him, giving nothing away of who is underneath it. It doesn’t matter who it is, they’re just going to be an outlet for the anger brewing underneath Liam’s skin. He grabs the edge of it, ripping it off to see who it is and knocking their hood off in the process.

Theo.

His stepbrother stares up at him, his lips parted as he pants for breath. Liam had planned to beat him black and blue, but his hard cock pressing against the zipper of his jeans gives him a different idea. He grabs Theo’s jaw with one hand as he uses his other hand to unbuckle his belt.

“Please…don’t…” Theo’s voice is soft, but he doesn't fight against him. He doesn't do anything to actually make him stop. Maybe he actually wants this. Liam pitches his voice lower, he doesn't want Theo to know it's his younger stepbrother that’s going to fuck his throat.

“Look at you, you aren't even fighting me.” He pulls his hard cock out, stroking it once before pressing the head against Theo’s parted lips. “You want this.” A shiver races up Theo’s spine as Liam slaps the head against his plush bottom lip. God, he’s harder than he has been in months. And it's all because of his stepbrother. Which really should be concerning, but he forces that to the back of his mind to deal with later.

“Open your mouth.” Theo stares up at him with wide, almost doelike eyes as he opens his mouth more. Liam moves his hand from his jaw, cruelly curling it into Theo’s dark hair.

“Tongue out.” His older brother whines as he sticks his tongue out. Liam slaps the head of his cock against it, groaning low in his chest. Theo moans softly as he does it a couple more times. He roughly shoves his dick into Theo’s mouth, the head hitting the back of his throat. Theo gags around him, but Liam keeps him held in place with a hand in his hair. He doesn't give a chance to adjust before he’s roughly fucking his throat. Theo’s hands shoot out to grab onto his thighs and for a moment he thinks that he’ll fight back, but instead he uses the grip to steady himself. Tears are welling up in Theo’s green eyes as he moans around him, the vibrations sending ripples of pleasure up Liam’s spine. Liam can still hear screams echoing out in the forest as the others are caught, but his attention remains on the man sucking him off.

“God, you like this don't you? Being used in the forest like the desperate slut you are.” His brother moans around him again. Theo curls his tongue against the underside of his dick as he shifts closer. Liam looks down to see Theo’s hard in his jeans. He lifts the toe of his shoe, pressing the tread of it against his cock. Theo keens in the back of his throat as he rocks his hips against it.

“You’re such a fucking slut.” He growls out. Theo keens again, dropping his hips down as he grinds against the sole of Liam’s shoe. Liam lets him as he continues to harshly fuck his mouth. Theo gags around him every time he forces his cock into his throat, but he still doesn’t do anything to stop him. Rather, he grinds down harder against the sole of his shoe. It’s like he’s getting off on being treated like a toy that exists solely for Liam to get off using. It doesn't take much more, not with the way that Theo keeps moaning around his cock, before Liam’s cumming down Theo’s throat. He struggles to keep his eyes open, the pleasure of it knocking into him like a goddamn bull. Theo swallows around him, tries to swallow all of his cum as he grinds his hips faster. Liam pulls back, shooting the last couple of ropes onto his tongue before he harshly pulls Theo off of his cock. He steps back from him, looking at Theo’s dazed face for a moment before tucking his cock back into his jeans. It suddenly hits Liam, he just face fucked his stepbrother. In the woods where anyone could have caught them. Panic sets in and before he can think about it, he hits Theo hard enough to knock him out. Liam leaves him there, returning back to Scott’s place.

Chapter Text

 

 

 

 

 

Theo stands under the warm spray of his shower, staring down at his hard cock. It's been like that every time he thinks of what happened in the woods a couple of nights ago. He still doesn't know who the masked person was, but he can't get the way they treated him out of his head. He wants to think that it was Liam, that sick obsession for his younger brother has him imagining him as the one under the mask. Liam growling at him as he forces his hard cock down Theo’s throat, choking him on it. He reaches down and strokes his dick, biting his lip to keep himself quiet. It's too easy to put himself back into that night, back down on his knees and being used for someone else’s pleasure. He swears he can still feel the weight of that thick cock on his tongue, in the back of his throat. Instead of some masked stranger, he imagines that it’s Liam fucking his throat. It’s Liam keeping him down on his knees as he takes his pleasure from Theo’s warm mouth, the tread of his boot pressing against Theo’s hard dick. He speeds up his strokes, feels that familiar tug of an orgasm growing in his balls. He’d never sucked anyone’s dick before that night, never really acknowledged that it was something he wanted. But it had been more than he’d ever thought it would be. He’d been hard the moment that person had demanded he open his mouth.

He’s pulled out of the fantasy when he feels a smaller hand knocks his hand away and takes over stroking his cock.

“Let me help with that.” Tracy’s voice comes from behind him. And just like that, his orgasm is gone. His cock is still hard as he bats her hand away.

“It's fine.” He says as he shuts off the water that's gone cold and gets out of the shower. He grabs his towel and wraps it around his hips, ignoring the bewildered look on his not-girlfriend’s face.

“You're still hard..”

Shocker. He thinks to himself. There hasn't been a moment that he’s not hard for days.

“Doesn't matter.” He says as he walks back into his room. Tracy hurries after him, grabbing a spare towel to cover her body with.

“Theo..” She tries again, but he ignores her as he gets dressed.

“Come on, we should be downstairs.” She huffs out a breath as she rushes to get her clothes on before following Theo down to the kitchen. Everyone is already at the table when they sit down and Theo makes sure to apologize to his mom for not being down sooner. She waves it off with a soft smile as she pushes a full plate towards him. He thanks her before digging into it. His stepmom is an incredible cook and he’s been in love with every meal she’s made since she started dating his dad. And ever since they got married, he’s been able to eat everything she cooks. Sometimes when Liam and his dad are gone, he helps her bake in the kitchen. It’s a special bond that he didn't have with his actual mom and he treasures every single moment of it.

Theo feels Tracy grab his cock through his jeans. He shoots her a ‘knock it off’ look, but she ignores it as she opens his jeans and pulls him out under the table. She strokes his cock as she holds a totally normal conversation with Hayden. Theo tries to bat her hand away, but she’s persistent. He gives up after a few tries, resigning himself to forcing himself through her antics. As he looks up from his plate, he catches Liam’s gaze. His brother has a knowing look in his blue eyes and for a moment Theo panics, but his cock twitches in Tracy’s grip despite that. Liam smirks at him, his eyes darkening as he watches him from across the table. Theo can feel himself hurdling towards an orgasm as he's held captivated by those eyes that haunt his dreams. God, he can't believe he’s going to cum with everyone in the room. Liam abruptly stands up from the table, startling Tracy enough to remove her hand. Theo wants to whine as he looks at his younger brother. He’d been so close, but Liam ruined it.

“You said you’d take me to pick up my car.” Liam reminds him. Theo sighs softly, regretting ever agreeing to that.

“Fine. Your ass had better be in the truck in the next five minutes.”

“Language.” Their mom chastises. Liam smirks at him before going upstairs, leaving Hayden at the table with them. Theo bites back a sigh as he tucks his dick back into his jeans, grumbling quietly under his breath. His phone buzzes in his pocket and he opens it without looking to see who it is.

Unknown: can’t stop thinking about you sucking my cock. Get hard just thinking about how pretty you looked down on your knees for me.

Theo stares at his screen.

Theo: Who the fuck is this?

Unknown: i'm hurt you don't remember me, Pup.

It can't be. Theo thinks to himself.

Theo: How did you get my number?

Unknown: don't worry about that, play a game with me.

Theo: What game?

Unknown: go into the bathroom and send me a picture of your cock.

Theo excuses himself from the table and hurries into the hallway bathroom. His hands shake as he stares at the open text thread.

Why is he entertaining this?

Why doesn't he tell whoever this is to fuck off and block their number?

Theo: I don't even know who you are, why should I listen to you?

Unknown: because we both know you want to

Theo: Tell me who you are first.

He sits down on the closed lid of the toilet, waiting for them to respond to him. His screen goes dark and for a brief moment he thinks he’s managed to scare off whoever was in the woods with him that night. But another moment later his screen lights up.

Unknown: image attached

Theo bites his bottom lip as he opens it up and sees that familiar cock. The one that wrecked his throat so thoroughly that he hadn't been able to speak for the next few days without sounding like he had just swallowed a fistful of glass. It’s thick and veiny, almost as long as his own cock. The hand that holds the perfect cock is almost familiar somehow, but he doesn’t think too much about it. No, his thoughts are filled with thoughts of choking on that cock, of it robbing him of his breath until he’s lightheaded.

He needs it again.

Unknown: your turn, Pup

Theo can't believe he’s doing this, can't believe he’s actually listening to this person. He stands up, thumbing open the button of his jeans and shoving them down enough to pull his cock out. There’s a pearl of precum at the tip and Theo can’t think of a time he’s been this hard for another person. He curls his fingers around his cock, biting his bottom lip to muffle the sound that tries to escape. His camera opens with an easy tap of his thumb and takes a few minutes to find the right angle. His hands tremble as he sends it, his heart thudding loudly in his chest.

Unknown: good boy. stroke your cock, make it leak for me.

Theo swallows hard as he stares at the new message.

I’m not actually going to this, right? He asks himself as he opens the camera again. He records a short video, stroking his cock a couple of times and smearing the precum from the head down the length. There isn’t a moment of hesitation as he sends the video.

Unknown: want to know what i’ve been thinking about since that night?

Theo: What have you been thinking?

Unknown: beg me

Theo rolls his eyes as he reads the text.

Is this guy for real? He wonders. He thinks about ignoring it, of not responding at all. But his throbbing cock has other plans.

Theo: Please tell me what you’ve been thinking about.

Unknown: you down on your knees like the desperate slut you are. choking on my cock as you claw at my thighs for breath. i wouldn’t let you go, you can die on my cock

Theo barely contains the whine that spills from his lips. His cock twitches in his hand and he has to tightly grip the base to keep himself from cumming like a teenager.

Unknown: is that what you want, Theo? to be ruined by my cock and left covered in cum?

Theo: Yes. I want you to ruin me.

Unknown: Stroke your cock, make yourself cum for me.

Theo moans softly as he opens his camera again, filming himself as he strokes his cock with quick, harsh strokes. He teases his thumb across the head, using his precum to slick his strokes. The pleasure is blinding, there’s nothing that compares.

Sex with his not-girlfriend pales in comparison.

He’s stroking his cock for some stranger, filming it even for the other man to use however he sees fit. Theo bites his bottom lip to muffle his moan as he cums. It drips down his fingers, falling to the floor with quiet sounds. He ends the recording, sending it before washing his hands in the sink and cleaning up the mess he made on the floor. As he tucks his cock back into his jeans, his phone lights up with a notification.

Unknown: knew you would be a good boy for me.

Theo swears his heart leaps up into his throat as he reads the text again and again. He’s never had someone call him that, never known that it was something he wanted someone to call him.

Theo: You did?

Unknown: yes

The masked person doesn’t elaborate more than that. Theo chews on the inside of his lip as he stares at the screen until it goes dark. He’s going to figure out who this person is.

Liam’s been more distracted than normal, the burner phone burning a hole in his pocket. Hayden doesn’t seem to have noticed. No, she’s been too busy posting their “perfect” relationship on instagram. She tags him in everything and it always has some caption to it that leaves him feeling sick to his stomach. Maybe Mason is right, maybe he needs to break things off with her. Especially before things go any further.

“Dunbar!” He jolts in his spot on the field, looking over at his coach.

“Yeah?”

“Pay attention or you’re all running lines!” Liam sheepishly scratches the back of his neck before nodding. He needs to get over whatever is going on. Theo hasn’t reached out to the unknown number.

Why would he?

Liam shakes his head and lets himself fall into the thrum of lacrosse practice.

 

Theo is waiting for him outside in the truck. Tracy is sitting in the front seat and it fills Liam with an inexplicable sense of anger. He walks over to the truck, ripping the door open and staring at Tracy’s startled expression.

“Move.” Liam demands. It takes a moment for Tracy to collect herself, but when she does she shakes her head.

“No, it doesn’t make sense for you to always be in the front. I’m Theo’s girlfriend, I should sit next to him.” He watches as his older stepbrother rolls his eyes.

“Trac…” Theo starts before Hayden comes jogging up to them. She grabs Liam’s arm as she plasters herself against his side.

“She’s right, we should sit in the back together.” Her eyes gleam with something that Liam really doesn’t want to decipher. Tracy nods along with her words like her friend is making perfect sense. Liam looks between all of them, trying to figure out the best way to gently let Hayden down and get Tracy out of his spot. Theo ends up being of no help, why would he be. Liam’s grip on the door tightens.

“Fine.” He goes to slam the truck door shut, stopping when he sees Theo’s glare. It ignites more of that boiling anger in his chest and he slams it shut purely to piss off his brother. He opens the back door and gently ushers Hayden in, smiling at her as she slides into the back. The smile feels unnatural on his face, forced when all he wants to do is smash Theo’s face in. He climbs into the truck, closing the door just as harshly as he did with the passenger door. Hayden slides across the seat and leans her head against his shoulder. Liam catches Theo’s gaze in the rearview mirror.

“Slam my doors like that again and I’ll kill you.” He seethes. Liam smirks at him, pleased to have gotten any reaction out of him. Theo holds his eyes for a moment longer before driving them back to Hayden and Tracy’s apartment. Liam glances down to look at his girlfriend, watching her scroll through all the comments and likes her most recent post has gotten. He’d taken her out for something he can’t really remember what it was, but she’d snapped a picture of them. She looks so happy in the picture while Liam looks like he’s being held at gunpoint to be there. It fills his chest with guilt, he doesn’t love her anymore. Not like he did when they first started going out. Now he wants to be as far away from her as possible. Hayden looks up at him, giving him a soft smile before snuggling herself closer to him. Liam turns his head and stares out the window, refusing to acknowledge the empty feeling in his chest. He half listens to the conversation between Hayden and Tracy, something about another party for someone’s birthday. Liam doesn’t really care, he doesn’t want to go to another party. He barely stops himself from jumping when he feels her hand on his thigh, feels it inching higher and higher until she cups him through his jeans. Liam’s gaze jumps over to her as he reaches down and grabs her wrist. He tries to move her hand away, but she tightens her grip.

“What the fuck are you doing?” He quietly hisses out.

“Come on, we haven’t done anything in months. It’s like you don’t want me anymore.” She keeps her voice just as low as his.

“You’re not touching my dick in the backseat of my brother’s truck.” Hayden pouts up at him.

“Why not? Tracy’s probably doing the same thing right now.” It takes every iota of strength for Liam to not let his eyes jerk up to see if she’s right. He can’t hear anything, but that doesn’t mean anything. He pulls Hayden’s hand away, setting it in her own lap.

“No, Hayden.”

“Fine.” She huffs out before scooting across to the side of the backseat. Liam feels a little guilty but turns his attention away from her. He pulls out the burner phone and opens up the only text message in it.

 

Unknown: if your girlfriend is touching that pretty dick, im going to break her fingers.

Liam watches Theo, waits for him to give some kind of reaction but he doesn’t. It isn’t until they’re in front of the girls’ apartment that he sees Theo open his phone.

Theo: Jealous?

Liam grinds his teeth together so hard, he’s afraid he’s going to crack a tooth.

Unknown: im not playing around, Pup. she’d better keep her hands off of you.

He waits a moment before sending another text.

Unknown: In fact, get rid of her or i’ll send that video to your brother. see how he feels about you sending videos like that to strangers.

Liam watches as Theo’s face pales and his hands tremble around his phone.

Theo: Don’t do that.

Unknown: Then get rid of her.

He tucks the phone back into his bag and gives Hayden a half hearted goodbye, promising to text her later. Liam watches as Tracy leans over to give Theo a kiss and watches with unrestrained joy as Theo moves away from her. She looks confused for a moment before getting out of the truck.

“Call me later?” She asks. Theo shrugs.

“Maybe.” Tracy makes a noise of frustration before turning and walking into her apartment. Liam climbs out of the back and quickly takes his normal seat.

“What was that all about?” He asks as Theo begins driving again.

“Nothing. Don’t worry about it.” Liam bites the inside of his lip as he turns his attention back to the passing scenery. Maybe he should give Theo a reward for putting such a quick stop to the back and forth thing with Tracy. He’ll wait until they get home to decide if he’ll give him something for being such a good boy.

They pull up to the house and Liam jumps out of the truck, leaving all of his lacrosse stuff in the back.

“Liam!” Theo shouts after him. He turns to look at him.

“Get your gear out of my truck.” Liam grins at him.

“No.” He says with a shrug before going inside. Liam closes his bedroom door behind himself, throwing his backpack haphazardly on the chair by his desk. He grabs the burner phone out of the front pocket before flopping down on his bed. Once again, he opens up the only text thread on the device.

Unknown: meet me at the school. 7pm don’t be late Pup.

Theo’s text back is almost immediate, like he had been waiting for it.

Theo: And if I don’t?

Unknown: Then you don’t get your reward for being a good pup.

Liam’s screen goes dark while he stares at it waiting for his older stepbrother’s response.

Theo: Fine. I’ll be there.

Liam grins at the response, now all he has to do is get the mask again. He tucks the burner into his nightstand drawer before grabbing his actual phone out of his back pocket.

Liam: Can I borrow one of the masks again?

Scottie: Uhm…sure? You’re not doing something weird with it right?

Liam laughs to himself as he goes to reply another text from Scott comes through.

Scottie: Actually, I don’t want to know. Just come pick it up whenever.

It’s time to put his plan into action. He grabs his hoodie, the keys to his Bronco, and the burner phone again. As he jobs down the stairs, he spots his mom. He gives her a soft smile and an excuse about meeting up with friends. She kisses his cheek and reminds him to be safe before sending him off.

Liam parks his car down the road, passed the school where he knows that Theo won’t see it. He climbs out of the car and heads into the school, knowing exactly which door is unlocked. It doesn’t take long for him to find his way into the office and to connect his phone to the bluetooth sound system the school installed last year. The burner phone dings with a notification.

Theo: I’m here.

Liam grins down at the screen, pleased that Theo actually decided to meet him here.

Theo: You didn’t pussy out, did you?

Liam can’t help the chuckle that slips out. Of course he didn’t back out. Why would he when he has his brother exactly where he wants him? He opens up a playlist that he made after picking up the mask. Pressing play on it, he lets music start before turning the volume up, not quite deafening but enough that Theo won't hear him coming. He pulls the mask over his face and the hood up over his head. With a last glance at the camera’s, he makes a mental note of where Theo is.

The office door creaks as he leaves and heads towards the last place he saw his brother. He doesn’t bother to keep his steps quiet since the music muffles out most other sounds. He finds Theo standing in the library, oblivious to his arrival.

Perfect.

Liam walks up behind him, grabbing him and shoving him down against the closest table. Theo struggles against him, kicking back at him until he catches sight of the mask.

“Hello, Pup.” Liam pitches his voice low again. Theo pants against the cold wood, glaring back at him.

“Get off of me.” Theo grits out. Liam leans down until the cold, plastic mouth of the mask brushes against his older brother’s ear.

“Run.” He pushes off of him, taking a couple of steps back. He watches as Theo rights himself before looking back at him. Theo seems to hesitate for a moment before taking off running. Liam counts in his head, giving him a few second headstart before chasing after him. It doesn’t take long for him to catch up to him, watching as Theo glances back to see him. The fear he catches in his eyes is exhilarating. Theo grabs onto a doorway and uses it to propel himself into a classroom. Liam isn’t far behind him, grabbing the back of his shirt and using it to slam him up against the chalkboard.

“It’s like you don’t want to escape from me, Pup.” Theo throws an elbow back, catching Liam in the chest. It knocks the wind out of him and he loosens his grip. His brother spines around before shoving him hard against the desk.

“Fuck you.” He seethes before running out of the classroom. Liam smirks behind the mask, running a hand over the where there will surely be a bruise later. He walks back out of the classroom, glancing both ways down the hallway to try and figure out which way his brother went. After a moment, he heads farther into the school. Theo wouldn’t have ran out of the building, not when they’re finally getting to play their game again. Liam walks down the hallway, peering into the different rooms.

“Come out, Pup.” He goes to look into another room when he hears a door down the hall slam shut.

Got you! Liam thinks to himself as he runs down the hallway. He catches sight of Theo turning down another corner. His stepbrother really thought he could throw him off his trail with something so stupid. Theo stays ahead of him for a bit until he runs into a larger classroom. Liam stands in the doorway, escaping Theo’s escape route.

“No where to run now, Pup.” Theo stares at him for a moment before glancing over his shoulder at the door at the top of the room. Liam slowly walks into the room, Theo taking a step back every time he takes a step forward.

“You can’t escape me.” Theo turns and runs up the stairs, jumping over one of the tables. Liam watches as the toe of his shoe gets caught and sends his brother sprawling on the floor. He takes the chance to pin Theo down, his knees bracketing his brother’s hips. His brother’s breaths come out in short pants as he continues to fight against him. Liam pins his hands down on the floor.

“Get off of me!” Theo yells. Liam smirks behind the mask as collects both of Theo’s wrists in one hand.

“You don’t want that, look at how hard you are.” He teases his fingers across the bulge in his brother’s jeans. He watches Theo’s eyes flutter a little before his stepbrother glares at him again.

“Don’t…don’t touch me…” But Theo’s actions belie his words. He’s stopped fighting against him and instead relaxing into the firm grip on his wrists and the weight of Liam’s body over his. Liam strokes his fingers over Theo’s covered cock a few more times before cupping him through the rough fabric. He leans back, pulling out a small length of rope from the pocket of his hoodie.

“Now, be good for me Pup.” Theo stares up at Liam as he ties to the rope around his wrists. The black rope contracts nicely with his stepbrother’s pale skin and he takes a moment to run his fingers across the crisscrossing pattern he’s made. He looks back down at his brother and notices an odd look in his eyes, almost like he recognizes him. But that can’t be possible, the mask covers his face entirely. Liam chooses to ignore and focus on giving his brother the reward he’s had planned for him since this afternoon. He shifts back until his knees are bracketing his brother’s thighs and thumbs open Theo’s jeans. He pulls his jeans and boxes down until they get caught around his thighs, watching as it slaps up against the bottom of Theo’s shirt and leaves a thin, clear string of precum.

“All this, just from being chased.” He taunts as he teases two fingers across the head. Theo shivers underneath him, but doesn’t say anything in his own defense. Liam curls his fingers around his cock, stroking him once from base to tip. Theo moans softly, staring wide-eyed up at the blank mask.

“You’ve earned a reward for being so good for me, Pup.” Theo opens his mouth to respond, but Liam doesn’t give him the chance as he starts stroking him with a firm grip. He twists his wrist on an upward strokes, watching as his stepbrother’s hips jerk up into his fist. God, Theo is so hot like this. Unrestrained moans spilling out his mouth as he fucks up into his fist, pleasure written through every fiber of his being. He wishes he could take the mask off and kiss him, like the taste of his moans out of his mouth. But Liam can’t, he has to settle himself with being a masked stranger that uses his stepbrother’s body. He swipes his thumb across the head, collecting Theo’s precum and using it to slick his strokes.

“Please…please…please…” Theo begs as he strokes him faster. He slips his other hand down, cupping his balls and feeling the weight of them. He gently rolls them in his hand, watching the way his brother’s back arches and his hips jerk up.

“Go on, Pup. Cum for me.” Liam watches Theo’s eyes roll back as he cums. Ropes of cum cover his hand, the bottom of Theo’s shirt, and some even gets on his hoodie. Liam strokes him through it until Theo is whining and shifting underneath him from the oversensitivity. For a brief moment, he thinks about not stopping; about stroking his cock until he’s hard again and making him cum again. But not tonight, Theo needs to earn that. Liam brings his hand up to Theo’s mouth.

“Clean it up.” He watches as his stepbrother’s lips part and his tongue licks up one of his fingers. Liam is completely enraptured as he watches Theo clean his cum off of each finger, his tongue curling around them and pulling them into his mouth. He sucks Liam’s fingers clean, not knowing that they belong to his younger stepbrother. Liam can’t help but remember what Theo’s mouth feels like on his cock, the way he curled his tongue against the base. He forces himself to pull his fingers out of Theo’s mouth, wiping his spit across his cheek.

“Good luck, Pup.” Liam stands up, wiping the rest of Theo’s spit on his jeans before walking out of the classroom. Leaving his brother there to figure out how to get out of the ropes.

Chapter Text

 

 

 

Theo stands in the bathroom, staring at his reflection in the mirror. He tugs the sleeves of his shirt down to hide the ropemarks that are still there from that night in the school. It had taken him a while to figure out how to get out of the ropes, the masked stranger had tied the rope fairly well. There had been something strangely familiar about his masked stranger, but at the time he couldn’t put his finger on it. Now though, he’s had time to think about it. Time to think about those blue eyes that have haunted him long before the party, long before he was on his knees in the woods for someone he didn’t think he knew.

Liam.

There had been no mistaking those blue eyes or the dark woodsy smell that had enveloped him, the one that was inexplicable Liam. He hadn’t ever really thought about what Liam smelt like, not until he’d gone into the bathroom after his younger stepbrother had taken a shower and been hit with the intoxicating smell. It had felt like he couldn’t control himself as he’d walked over to the shower, inhaling deeply to try and write the scent into his brain.

Theo shakes his head like he’s shaking the memory away. He needs to focus, needs to figure out how to get Liam to admit that he’s the masked stranger. Because he obviously can’t confront him about it, Liam would never just admit to it. No, he has to be strategic about this. He could sneak into Liam’s room while he’s at lacrosse practice. It’s not like Liam would notice if his room was more of a mess, but he would if Theo cleaned anything up. And with the mess he knows that’s in there, it would be hard not to clean something up. He sighs softly, rubbing his thumb over the rope impressions. A hard knock on the bathroom door startles him from his thoughts.

“Dude! Come on, I want a shower before class starts!” Liam yells through the bathroom door. Theo walks over and unlocks the door on Liam’s side of the bathroom, opening it before leaning against the doorframe. He folds his arms across his chest, smirking as he looks at him.

“Don’t get your panties in a twist, all you had to do was ask.” Liam doesn’t respond to him and it takes him a second to realize that his brother is staring at the marks on his arms. His first instinct is to pull the sleeves of his shirt down again, but the part of him that wants to prove that it’s Liam under the mask shoves that instinct back.

“Hello? Earth to Liam?” Blue eyes snap up to meet his and his cheeks flush red.

“What?” Theo rolls his eyes, hiding his amusement.

“Bathroom is yours.” He says before pushing himself off of the doorframe and heading back into his own room. As the shower starts, Theo decides that he’ll go through Liam’s room while he’s at practice. It’ll be when he has the most time away from his stepbrother to gather his proof.

 

Theo toes his boots off at the front door, listening for the sounds of their parents. When he doesn't hear anything, he breathes a sigh of relief. Their parents being gone means that he won't have to think of some explanation for being in Liam’s room. He heads up to his room, setting his bag down next to his desk. He doesn't give himself to second guess what he’s doing, just heads back out of his room and into Liam's. Once the door is closed, he leans back against it and glances around. Liam wouldn’t leave it in an obvious place, so he’s going to have to do some digging. Theo starts with Liam’s desk, pulling all of the drawers open and shuffling through everything that’s inside of them. But he doesn't find the mask there. Next is the closet with the same results. Even the shelves are void of the mask. The side tables are also a bust and Theo flops back on Liam’s unmade bed with a groan of frustration. He hadn't expected Liam to actually be good at hiding the damn thing. Theo closes his eyes, letting the comforting smell of Liam envelope him. He knows that LIam wouldn’t have taken it to school with him, not when it would run the risk of someone else finding it and discovering the fucked up mind game he’s been playing. No, it has to be here.

Somewhere.

Theo’s pulled from his thoughts when he feels his phone vibrate in his pocket. He shifts around a little, pulling it out of his pocket as he lays his head on Liam’s pillow. There’s a tremor of excitement in his hands at the possibility that it’s his masked stranger.

Little Wolf: gttng ride frm mas b hme soon

Theo can’t help but roll his eyes at Liam’s abhorrent texting. He almost never uses full words, choosing instead to shorten every word as much as he can. A bolt of panic surges through his chest as he rereads the text.

Liam will be home soon.

Theo scrambles to his feet, tripping on Liam’s comforter and falling flat on the floor. It takes a minute to untangle himself and he throws the blanket back up onto the bed. He sees something, a box tucked neatly under the bedframe. With trembling hands, Theo pulls the box out and opens it.

Empty eyes of a black mask stare up at him and Theo’s heart leaps up into his throat. It was Liam. The night of the party when they were out in the woods, last night in the school, haunting his dreams, and the one that’s been texting him obscene things. He stares at the mask for so long that he loses any sense of time. He’d thought that it was Liam, had hoped that it was his younger stepbrother. And here is the proof that it’s been him the entire time. Theo startles when he hears the front door close. He quickly puts the lid back on the box before shoving it under Liam’s bed again. He scrambles to his feet and rushes out of his younger brother’s room, nearly running right into him.

“What are you doing in my room?” Liam asks, sounding almost cagey. Theo rushes to find an excuse, anything to use as a reason for being in there.

“Looking for my sweater. You know, the one you’re always stealing.” He says as he stares at the sweater Liam is currently wearing. Theo watches Liam’s cheeks flush with color.

“It got mixed in with my laundry…” Liam mumbles. Theo raises a brow at him since he knows that’s a lie. They do their own laundry, the only way his sweater would have ended up in Liam’s laundry is if his stepbrother stole it from his room. He stares at Liam until his cheeks flush with anger. He watches him struggle out of the sweater before his brother throws it at him.

“Take it!” He huffs out. Theo catches it before it hits him in the face, but the deep woodsy smell still fills his senses. His eyes are drawn to the dark bruise hidden underneath the thick thatch of hair on Liam’s sternum and instinctually he knows it’s from where he elbowed him. His jeans start to tighten and he quickly drops the sweater down to hide his growing erection.

“What happened to you?” Theo hopes he manages to keep his voice steadier than it sounds. Liam glances down at his chest.

“Lacrosse practice.” Theo makes a noncommittal noise.

“Don’t let mom see it.” He says before moving past Liam and going into his own room. Once the door is closed, he leans against the solid piece of wood and breathes a sigh of relief. He found what he was looking for, escaped Liam’s notice, and got his sweater back. Now, he can put his focus on figuring out how to get Liam to admit that he’s the masked stranger. But for the moment, he can relax. Theo brings the sweater up to his nose and inhales the intoxicating smell of his stepbrother. He bites his bottom lip as he pulls his shirt, throwing it into his room before pulling his sweater on. His sense of smell is completely overwhelmed by Liam’s smell and Theo has to bite his lip to keep himself from moaning. Once he has the sweater on, he walks over to his bed and flops back onto it. He practically burrows himself into the encompassing smell, his dick throbbing against the zipper of his jeans. As he brings the collar of the shirt over his nose, his other hand slips down and palms over his erection. A soft moan spills from his lips and any pretense of drawing this out, of teasing himself, flees his mind. He pops open the button of his jeans and kicks them off along with his boxers, leaving him in just the sweater. His fingers wrap around his cock, smearing the already leaking precum along the length. He quickly strokes himself, mimicking the way that Liam had done it a few nights ago. But now instead of a blank mask staring down at him, Theo imagines his stepbrother. It's Liam leaning over his prone body as he taunts him for making such a mess. It’s Liam calling him a desperate slut. Theo tries to bite back the moans spilling from his mouth, but he's mostly unsuccessful. All Liam would have to do is press his ear to the door and he'd hear every desperate moan coming from him. He brings his free hand down and swipes two fingers through his precum, spreading the sticky substance along them before slipping his hand farther down and teasing the tips against his hole. He's never had someone touch him there, never done it himself either. But he so desperately wants Liam to, wants his stepbrother to fuck him until Liam’s name is the only thing he can remember. Slowly, Theo presses a finger inside of himself. His breath catches for a moment before coming out in a louder moan.

Fuck…

He hadn't expected it to feel like this, for it to feel so good. After a few experimental thrusts, he presses the other finger in a long side the first one. The stretch feels incredible and another moan spills from his lips. He matches the pace of his fingers to his strokes. Unrestrained moans fill his room and Theo couldn't stop them even if he wanted to. His fingers brush against something on a thrust that has his brain short circuiting and his eyes rolling to the back of his head.

Fuck. Fuck. Fuck. He chants in his head as he angles his fingers to brush against that spot again and again. His cock twitches in his hand and he can already feel himself barreling towards an orgasm. He tightens his grip on his cock, stroking himself at an almost cruel pace. Liam wouldn't go easy on him, wouldn't give him a break once he realized how close Theo is. It only takes a couple more strokes before Theo is biting the fabric of his shirt as he cums, muffling the sound of Liam’s name falling off of his lips like a mantra. He continues to fuck himself with his fingers until his legs are shaking and he’s oversensitive. With a whine, Theo pulls his fingers out. He grabs a couple of tissues and cleans up the mess on his hand and his stomach. He tosses the dirty tissues towards his small trash can, not even bothering to make sure they go in. He climbs under his comforter, tucking his nose into the neck of the sweater and breathing in Liam’s scent as his eyes drift closed. He’s almost asleep when he hears the quiet snick of his door closing. Theo smiles to himself, he’ll get Liam one way or another.

 

Theo wakes up to the familiar smell of his stepmom’s cooking. He glances towards his window, noticing that it’s brighter out now than it was when he fell asleep. He pushes himself up onto an elbow, dragging his other hand down his face. That orgasm took more out of him than he thought if he slept through the rest of the day and into the next.

Thankfully, it’s Saturday so he doesn't have to worry about having slept through his classes. He knows that neither of his parents would be upset with him, but he would be with himself. They're paying for his college education and letting him live rent free in their home, the least he can do is go to his classes when he’s supposed to. Theo stretches before getting out of bed. His nose wrinkles at the tacky feeling on his stomach. Clearly, he didn't clean up that well if he can still feel some of his cum on him. He grabs a clean towel out of his closet and some fresh clothes before going into the adjoining bathroom. After setting everything down, he turns the water on and lets the room fill with steam. He takes his sweater off, setting it gently down on the counter. He isn't ready to wash it despite finding flecks of dried cum on the edges. Theo knows he won't wash the piece of clothing until he can't smell Liam on it anymore. Then he’ll have to sneak it into his stepbrother's room and steal it back after he wears it again.

Theo looks at the sweater one last time before turning and climbing into the shower. He easily falls into his normal routine and blocks out anything else. His eyes are closed as he washes his hair and he doesn't hear the sound of the door opening or closing. He does, however, feel someone's eyes on him through the frosted glass of shower walls. Wiping the water out of his eyes, Theo looks to see the blurry figure of his stepbrother. Almost like a Pavilion response, his cock starts to fill with blood.

“Liam?” His brother doesn't respond to him, instead folding his arms over his chest. Theo squirms under the intense gaze. He knows that his brother can't really see him through the glass, but that doesn't stop his cock reaching a full erection.

“I'll be done in a minute, then you can have the shower.” Liam still doesn't respond to him. Instead, he moves towards the shower and pulls open the door. He corners Theo in the shower, staring at him like he’s something to eat. It sends a shiver down his spine and for a moment he doesn't know if it's the intense look in Liam’s eyes or the cold glass against his back.

“Li?” He tries again as Liam presses closer. The water has completely soaked through his clothes and the feeling of his wet shirt dragging against his sensitive chest has Theo shivering again.

“You think you're so fucking smart, don't you?” Theo blinks owlishly at Liam, his brain struggling to catch up with the situation.

“What..?” He asks.

Get a grip. Theo tells himself, but it’s hard to do anything with Liam in his space like this.

“I know why you were in my room.” Liam scratches his nails down Theo’s chest, leaving behind a stinging feeling. Theo swallows softly, his heart racing in his chest. This is not how he had planned for this to go, but he can't deny the fire it’s lit in his stomach. Liam leans in closer, completely pinning Theo against the cold glass.

“You could have asked, but no. You had to go and figure it out on your own, didn't you?” Theo’s nodding to the question before he even has time to think or process what’s been said.

“Use your words, Pup.” The pet name falling off Liam's tongue has his cock twitching between them. He’s been dreaming of what it would sound like to hear his brother call him that and his imagination had entirely fallen short. Liam glances down, smirking when he sees how hard Theo is.

“Yes…” He breathes out. Liam rewards him by teasing his fingers along the underside of his dick. Theo muffles a moan by biting his bottom lip. Rage fills Liam’s blue eyes, taking them from that comforting blue hue to something more akin to the ocean during a storm. He grabs Theo by the jaw, tipping his head back until it thunks against the glass.

“Don’t.” He growls against his jaw. Theo’s lips part on a breathless noise.

“I want to hear every sound I wring from your lips.” Theo does his best to nod. Whatever Liam wants, he’ll give to him.

“Good boy.” Liam praises him before biting the curve of his neck. Theo keens high in the back of his throat, one of his hands shooting up and curling tightly in Liam’s hair. His stepbrother bites down harder as he strokes Theo's cock, blending the pain and pleasure in his mind until Theo can't tell up from down. Loud moans echo in the bathroom, unmuffled despite the shower still running. Liam releases his bite and turns Theo around before he can complain about the loss. He presses him up against the glass as he shoves two fingers into his mouth, gagging him on them like he did with his cock.

“Suck.” He growls out and Theo does, sucking on Liam’s fingers like they're his dick. His brother isn't gentle about it, thrusting his fingers to the back of his throat and making him gag. After a few moments, Liam pulls his fingers out of his mouth and trails them down Theo’s spine before dipping between his cheeks. Theo presses his forehead against the cool glass as he cants his back, giving his stepbrother a better angle.

“Desperate.” Liam spits at him before roughly pressing two fingers into him. Theo gasps, the stretch much more intense than it was last night. His stepbrother barely gives him a chance to adjust before he starts roughly fucking his fingers in and out of his hole.

“God, you’re gonna feel so good when I fuck you.” He can’t help but nod his agreement. He knows that when Liam fucks him, he’ll be ruined for anyone else. Theo presses his hands against the glass, trying to balance himself as he rocks his hips back to meet Liam’s fingers. Moans freely fall from his lips, the sound of the shower mostly muffling the noises. Liam adjusts the angle of his fingers a couple of times until he slams them into that spot that Theo had discovered last night.

“Li!” He arches his back as his stepbrother cruelly rubs his fingers against his prostate. Liam bites his neck again, bordering on drawing blood. In some far distant part of his mind, Theo knows that he won’t be able to hide the mark. Liam alternates between roughly fucking him with his fingers and cruelly rubbing his fingers against his prostate until Theo’s thighs are shaking.

“Close…’m close…” He moans out. Liam smirks against his skin as he harshly thrusts his fingers into him again.

“Gonna cum for me?” Theo nods stupidly, unable to form an actual answer. Liam thrusts his fingers a couple more times, pulling his fingers out before Theo cums. He whines, high in his throat as his cock uselessly twitches a couple of times, but his orgasm has been ruined. Liam grabs him by the jaw, forcing him to look back at him.

“Please…please…” He begs, arching his back again and grinding back against Liam’s covered cock.

“You’ll cum when I let you cum.” He squeezes his jaw a little tighter. “But you have to earn that right.” Theo whines again as he stares at his stepbrother.

“Li, please. Please I need…” He trails off, unwilling to admit what he wants.

“No.” His response is firm, leaving no room for any argument. He holds Theo there for a moment before slowly releasing him. Liam leaves him there in the shower, hard and desperate for release. He hears the bathroom door close behind his brother and he leans heavily against the shower wall. Rage boils up in his chest. How dare Liam play with him, with his body like that and then prevent him from finishing. If Liam thinks that Theo is just going to roll over and obey his every command, he has another thing coming. He finishes his shower, a plan forming in his head.

Chapter Text

 

 

 

 

 

Liam stares at the burner phone, reading the text over and over again like he’s trying to either burn the words into his brain or figure out if Theo is being serious.

Theo: Meet me in the woods.

There’s no explanation, no reasoning, nothing. Just that one text.

Unknown: You think you make the rules now, Pup?

Theo: If you don’t want to, then I guess I’ll have to find someone who will.

 

Unknown: If anyone else touches you, I’ll kill them.

Liam grips the phone tightly in his hand. He’s not sure if his brother is trying to rile him up or if he would seriously find someone else.

No, Theo wouldn’t do that. He thinks to himself.

Unknown: I’ll be there.

If Theo wants to keep up this little charade of theirs, then who is Liam to deny him. He doesn’t know what his brother is planning or even why he suddenly texted the unknown number. Especially since he knows he’d found the mask the other night. It hadn’t been hard to notice, the box tucked too perfectly under his bed and the lid on just right. It had been the perfect trap to catch anyone that discovered it, specifically Theo. He knows his brother couldn’t resist putting whatever he found away in a neat, orderly way. Liam had thought that the illusion was shattered, thought that Theo would be disgusted. But he’d been wrong. When he’d gone to confront him about the truth, to try and explain what had happened. He didn’t really know what he was going to say or how he was going to explain choking him on his cock, coercing him into sending him that video, or chasing him down in the school. But he couldn’t risk losing Theo, couldn’t risk him not being a part of his life. When he’d opened the door to Theo’s room, he’d been stunned to see him with his nose tucked into his sweater and his hand around his cock. He stood there, enraptured by the sight. When Theo had fallen asleep, he’d quietly gone back to his. He hadn’t planned the escapade in the shower either. When he’d heard the shower running, he’d just wanted to see him. To watch him, but as soon as he saw him in the shower it was like something else had taken over.

Liam is pulled out of his thoughts when his mom knocks on his door, telling him that dinner is ready. Whatever Theo is planning, Liam’ll make sure he understands what happens when he tries to take control of their game.

 

 

Liam parks his car at the edge of the woods. Theo hadn’t specified where to meet him, so he assumes that he’ll have to track him down. He grabs the mask off the seat next to him, putting it on as he gets out of the car. When he looks up, he sees Theo leaning against a tree and there’s a smirk on his lips as he watches Liam. He smirks behind his mask, walking towards his brother.

“Stop.” Liam pulls up short, tipping his head to the side in confusion. He doesn’t say anything, just stares at his stepbrother. Theo pushes himself off of the tree and walks closer. Now that he isn’t slumped against the tree, Liam can see that’s wearing a crop top. It takes everything in him not to groan at the sight of his bare skin, his jeans sitting low on his hips.

“I want you to chase me again.” Liam nods, easily agreeing. “But there are rules.” He folds his arms over his chest, still staring at Theo.

“If you catch me, then I’ll be all yours.” Theo steps closer until he can run a hand down Liam’s chest. “But if you can’t catch me within the time limit, then I get to do whatever I want to you.” Liam doesn’t really see a downside to this arrangement. He still doesn’t know what his stepbrother is planning, or what he thinks that he could do to Liam that he wouldn’t want. Theo could do anything to him, but he didn’t say that. Didn’t tell him that he would give him the match to burn his life down with if it would make his stepbrother happy. He nods his agreement to Theo’s terms.

“You don’t have to be silent.” Theo’s fingers brush the bottom of the mask. “I know it’s you, Liam.” He says as he pushes the mask up until Liam’s mouth is exposed. Theo leans in closer, their lips almost brushing against each other as they share the same breath, the same air.

“What’s the time limit?” Liam asks, his voice coming out hoarse.

“Thirty minutes.” Theo pushes the mask up higher until Liam can’t see. He feels his brother lean in closer, feels his breath on his ear.

“Catch me, Little Wolf.” And then he’s gone. Liam tears the mask off just in time to see his stepbrother disappearing into the heavy woods. He tosses the mask onto the ground before chasing after Theo, he won’t let him get away. As he runs deeper into the moods, he can hear the sound of Theo’s laughter. He tries to follow it, but the sound echoes all around him.

“It’s like you’re not even trying.” Theo taunts him through the trees. Liam turns, catching sight of Theo’s pink hood. He runs after him, getting closer now that he’s caught sight of him. As he reaches out to grab him, Theo darts to the side and runs off again. His laughter trails after him as Liam feels his irritation growing. Liam continues to chase after his stepbrother, always so close to catching him but never getting his hands on him.

“Ten minutes.” Theo taunts him again as he escapes from Liam’s hands again. Liam’s irritation has shifted to rage, that familiar burning in his chest from when he was first introduced to his stepbrother coming back. He doesn’t know when his stepbrother suddenly picked up running or when he learned how to be so coy. Theo didn’t run like this before, but maybe that’s because he thought he was running for his life not taunting his stepbrother. Now, the game is different, but he won’t let Theo get away from him. Regardless of the rules or how easily he keeps slipping away. Liam pushes himself harder, getting closer to Theo again. But this time instead of trying to grab him, he tackles his brother to the ground. They hit the ground, Theo groaning as he’s pinned underneath Liam. Before he can think about trying to get away, Liam pins his legs down by sitting on his thighs. He leans over his back, letting his lips brush against his ear as he presses his erection against his ass.

“You can’t escape me, Pup.” Theo looks at him over his shoulder, smirking.

“Who says I wanted to?” God, Liam wants to wipe the infuriating smirk off of his brother’s lips. Maybe he needs to remind him which of them is in charge here, maybe Theo needs to be choked on his cock again. He’s so caught up in his thoughts, he doesn’t notice his brother shifting. The wind is knocked out of him as Theo elbows him in the chest like he did at the school. Liam jerks back, falling onto the ground in his surprise. Theo quickly gets to his feet and stands over him, smirking as Liam glares up at him. As Liam pushes himself up onto his elbows, Theo pushes him back down with a boot on his chest.

“Uh-uh, we’re doing this my way.” Liam’s glare deepens as his brother crouches down next to him. His head is jerked back when Theo threads his fingers into his hair.

“You’re going to get on your knees and suck me off.” Liam bares his teeth at him in a growl. Theo tightens his grip on his hair until his brother lets out a hiss of pain.

“Now, be a good boy and do as you’re told.” Theo doesn’t let up on his grip, instead using it to pull Liam up onto his knees. He uses his free hand to open up his jeans, shifting them down with his boxers. Liam’s mouth waters as he looks at his dick, but he can’t let his brother know how badly he wants it in his mouth.

“Open.” Liam licks his bottom lip before slowly doing as he’s told. Theo strokes his cock a couple of times, looking down at his younger brother before pressing into his mouth. For a moment, Liam thinks that Theo’ll take it slow, draw it out, but he’s quickly proven wrong when he fully thrusts into his mouth. He gags around him for a moment, glaring up at him as tears well up in his eyes and he tries to catch his breath through his nose.

“Not so easy, is it?” Theo taunts him. Liam glares up at him as Theo slowly pulls out until the head of his dick is pillowed on his bottom lip. They stare at each other for a few moments before Theo thrusts back in. Liam’s a little more prepared for it this time, breathing through his nose as his stepbrother fucks his throat but he still chokes every couple of thrusts. Theo isn’t gentle about it, but neither was Liam when the roles were reversed. His hands shoot up, grabbing onto his brother’s thighs to steady himself. He watches as his stepbrother sinks his teeth into his bottom lip, muffling the noise trying to leave him. God, he wants to hear him. Wants to hear the breathy noises Theo makes as he gets off like he did in the shower, or in his room. Liam grabs Theo’s jeans and pulls them down farther, letting them get caught around his knees. He teases two fingers over his brother’s balls, trailing them back to tease against his hole. Theo releases his lip with a gasp and his hand tightens in Liam’s hair.

“Wha..?” His question is cut off when Liam presses the tip of one finger into him. Liam feels him tighten up for a moment before he shudders and his body relaxes.

“Li.” Theo moans out as he presses his finger further into him. His body is torn between continuing to fuck Liam’s throat and rock back onto his finger. Liam curls his tongue against the underside of his cock as he pulls his finger back out. A whine leaves Theo and he’s left feeling empty when Liam brings his hand back.

“No, no, no Liam, please..” He whines. Liam tries to pull back, but Theo is quick to tighten his grip in his hair again. He breathes out through his nose, trying not to choke on him again as he reaches into his back pocket and pulls out a small packet of lube. He tears it open and gets two fingers coated in it as Theo watches him, his lips parted around a pant. The lube is discarded onto the forest ground and Liam thrusts both fingers into Theo keens again before rocking his back onto his brother’s fingers. He finds a rhythm, fucking into Liam’’s throat when he pulls his fingers out and pulling out of his mouth when he pushes his fingers in. His moans grow louder, filling the forest around them as he gets closer. Liam looks up at him as he changes the angle of his fingers and thrusts them against his prostate. The grip on his hair is borderline painful, but the noises spilling from his brother’s lips are worth it. His own cock is hard, pressing painfully against the zipper of his jeans and weeping for attention. But he keeps his focus on Theo and his pleasure. It isn’t long before Theo is close and Liam starts rubbing his fingers ruthlessly against his prostate.

“Li…Li please…don’t stop.” He breathlessly begs. Liam rubs his thumb against his perineum, giving him a little bit more stimulation against his prostate. Theo cums with a drawn out moan, his eyes rolling back before fluttering shut. Liam swallows everything as he continues to rub his fingers against that spot. A whine of overstimulation has him pulling his fingers out and Theo slowly pulls his cock out of his brother’s mouth. It takes some shifting, but Theo is able to get his jeans back up over his hips and his soft cock tucked back into them. He crouches down in front of Liam again and ghosts his free hand across the bulge of his jeans. Liam’s hips hitch forward, seeking out the pleasure he’s been denied all night.

“No.” Theo says as he pulls his hand away. “Maybe next time.” He releases his grip on Liam’s hair and shoves him down on the ground. Before Liam has even fully registered what has happened, Theo has disappeared into the woods. Liam lets out a growl of frustration as he pushes himself up onto his feet.

Theo doesn’t get to act like a brat and get away with it.
