Chapter Text

Tadashi pressed a button on his computer and watched as the robot rose up to hover at a level with his face. He grinned. The first version of his new project was working, so far.

“Good day”, the robot said in a stilted voice. “I am CalmBot. How can I be of assistance to you?”

“Can you go through a relaxation session with me?” Tadashi asked, trying hard to keep the excitement out of his voice.

“Of course”, CalmBot replied. “Please find a comfortable place to sit and notify me when you are ready.”

Tadashi moved to a couch beside his work table and dropped into it. CalmBot followed him, remaining at eye level.

“I’m ready”, Tadashi said.

The robot whirred as it began to run through its program. Tadashi could hear it speak, but the words all blurred together. He felt himself relax as CalmBot continued to speak. Tadashi’s eyes closed and his world narrowed to the robot in front of him. Nothing else seemed to exist; nothing else seemed important.

Tadashi opened his eyes. He felt calm and relaxed, as if he’d had a good night’s sleep. He looked around the room blankly until his eyes focused on the robot in front of him. For a moment, Tadashi didn’t recognise his invention. Then, it flooded back to him. He smiled. The test had been a success.

Tadashi stood up. As the remnants of the calm mood slowly faded away, he walked into the next room. It was quiet except for tinkering of metal from one of the benches. Tadashi walked over to it. Wasabi was hard at work. He had stripped off his lime green sweater, leaving him in a pale yellow tank top. As Tadashi approached, Wasabi looked up from his work, his eyes amplified by a pair of lenses. He blinked owlishly at Tadashi, then pulled the glasses off his eyes.

“Why are you grinning like that?” Wasabi asked, scowling at Tadashi.

Tadashi didn’t understand why his friend was so unhappy.

“It worked”, he explained. “My robot works.”

“Which robot is this?” Wasabi asked.

Tadashi turned to gesture at CalmBot, who had followed him from his desk. The robot glided closer so that it hovered between the two of them.

“My relaxation bot”, Tadashi said.

His calm mood was beginning to evaporate under Wasabi’s questioning.

“Great”, Wasabi said curtly.

He donned the lenses once again and resumed working. Before Tadashi could walk away, Wasabi cursed. He picked up the intricate metal object he had been working on and threw it to the ground. Metal strips and gears spun across the space. Tadashi frowned at his friend.

“What’s wrong?” he asked.

Wasabi put his head in his hands and took a deep breath to steady his nerves. Only when he felt like he could speak without screaming, did he look back up at Tadashi.

“It’s this new device I’m trying to build”, Wasabi explained. “I’ve tried time and time again, but it just won’t fit properly.”

He was getting angrier as he spoke. Tadashi placed a hand on his friend’s shoulder. Wasabi looked at him apologetically and smiled sheepishly.

“Sorry”, he muttered.

“You won’t be able to do all that fine work if you’re angry. How about”, Tadashi said with a grin, “I help you relax?”

Wasabi glanced at the robot that was still hovering in midair beside them.

“I guess you’re right”, he said with a sigh. “A break may do me good, either way. What do I need to do?”

Tadashi led Wasabi over to a couch and got him to sit down. He perched on the arm of the couch beside his friend. CalmBot had followed them and was now hovering in front of Wasabi.

“CalmBot, could you take Wasabi through a relaxation session?” Tadashi asked.

The robot beeped a couple of times and scanned Wasabi.

“Of course”, CalmBot replied. “I have the appropriate session for him.”

“Ready?” Tadashi asked.

“I guess”, Wasabi said, with a grin at his friend.

CalmBot began the relaxation session. At first Tadashi kept an eye on Wasabi, watching how he progressed through the session. But soon, the robot’s words took hold of him too. Tadashi felt his eyes close. He tried to fight it, but the desire to sink down was too strong. Tadashi relaxed his body, but his precarious position meant that he slid off the couch arm and onto the floor. 

Tadashi blinked his eyes open and felt his mind surface. CalmBot had ceased speaking at the loud sound, but Wasabi remained sitting on the couch. Tadashi looked at his friend. Wasabi’s eyes were closed and he was breathing deeply, his anxious mood from earlier no longer apparent. Tadashi turned his gaze to CalmBot.

“Why is he like that?” he asked the robot.

“My protocol recommends not to stop a session part way through”, CalmBot explained in its monotone voice. “I have kept Wasabi in this state due to the loud noise. Do you wish for him to be awakened?”

Tadashi looked at Wasabi. The sight stirred something deep inside him.

“Not yet”, Tadashi said slowly, trying to work out his feelings. “I’ll let you know when to continue.”

Tadashi breathed in deeply, trying to recover the calm state he had been in when thinking had been a lot simpler. It was hard to go back to it. Instead, Tadashi decided that what he needed to do was follow his instincts. He stepped towards the couch and immediately felt like he was doing the right thing. Tadashi looked again at Wasabi, this time seeing him in a different way.

The tank top Wasabi wore was tight around his chest, not leaving a lot to the imagination. Tadashi could almost see the curves of all his muscles. He knew that Wasabi spent a lot of time working out, but Tadashi had never had the desire to investigate further. Now, he wanted to understand his friend better.

Tadashi dropped onto the couch beside Wasabi. Immediately, he slid his hands over Wasabi’s body, cupping each of his well-developed pectoral muscles. It felt right. Tadashi could feel Wasabi’s nipples, now hard, pressing against his palms. He rubbed at them, feeling pleased when Wasabi let out a quiet moan. Tadashi moved his hands down, rubbing at Wasabi’s abdominals. He glanced down and blushed when he saw the bugle. It seemed that even in this trance-like state, Wasabi’s body was enjoying what Tadashi was doing. That knowledge sent a bolt of electricity straight down to his cock, which began to grow.

Without knowing why, Tadashi climbed onto Wasabi’s lab, straddling him. He groaned at how close he was to his friend. Tadashi continued to rub Wasabi’s chest and arms, one hand sliding beneath the tank top. He pulled the fabric up, exposing more skin. Tadashi had seen Wasabi naked in the past, but it had never interested him before. When he pulled off Wasabi’s top, Tadashi stared at the muscular torso, exploring it with his hands and his eyes.

Arousal began to pool in Tadashi’s groin. His cock was now completely hard, pushing against his pants. Tadashi shifted his position, groaning as his bulge pressed against something else hard. When he realised it was Wasabi’s cock, just as engorged as his own, Tadashi’s moans increased. In fact, Tadashi found that he couldn’t stop moaning. Part of him felt guilty about what he was doing, but the overwhelming majority of his brain was telling him how good it felt.

Tadashi bent down and pressed his lips to Wasabi’s forehead. Slowly, he worked his way down, stopping to kiss his friend deeply on the lips. Wasabi moaned loudly when Tadashi’s mouth latched onto a nipple and Tadashi felt pride grow inside him, knowing that he was the one making Wasabi feel like that. He slipped off Wasabi’s lap to kneel between his legs as he continued down.

Now, Tadashi was at eye level with Wasabi’s crotch. From this angle, the bulge looked massive. With trembling hands, Tadashi unbuttoned and unzipped Wasabi’s pants. It turned out that Wasabi wasn’t wearing underwear, because his dark cock flicked out, hitting Tadashi on the face.

“Wow”, he breathed.

Tadashi inhaled, taking in the odour of Wasabi’s member. There was something intoxicating about it, something that made Tadashi’s body tingle. He couldn’t help opening his mouth and taking Wasabi’s cock inside. It tasted faintly of soap and sweat, but the feeling of the massive member filling his mouth made Tadashi even harder.

As he tried to take as much of Wasabi into himself as possible, Tadashi reached down to free his own cock. It was painfully hard and leaking precum. Tadashi immediately started stroking himself. He moaned and the sound vibrated through Wasabi’s cock.

Tadashi could feel Wasabi’s cock pulsing in his mouth. He choked as he tried to force the member into his throat, but resumed trying as soon as he recovered. Tadashi lost track of time as he sucked off his friend and stroked his cock.

There was no warning when Wasabi came. Suddenly, Tadashi’s mouth was filled with his load. Without hesitation, Tadashi let it slide down his throat. The feeling of his friend’s seed inside him pushed Tadashi over the edge. He moaned around Wasabi’s cock as he came as well.

Wasabi’s softening cock slid out of Tadashi’s mouth. Tadashi remained on his knees staring up at his friend. Wasabi’s eyes remained closed, but he began to move, pulling up his pants and straightening his top. Only then, did he open his eyes. Wasabi didn’t seem to realise that Tadashi had just sucked his cock, nor that his friend was still on his knees with his own member out. Instead, he smiled contentedly.

“I feel like I just had a good night’s sleep”, Wasabi said. “That robot of yours does good work.”

He smiled down at Tadashi, then stood up. Tadashi watched as Wasabi returned to his own project, now more calm and focused. Tadashi, however, was trying to work out why he’d decided to suck his friend’s cock. It had seemed the right thing to do, but he had never had those urgings before. Tadashi slowly picked himself up and cleaned himself. He glanced at CalmBot, who was still hovering in the same place. He just hoped that he had programmed the robot correctly.

Chapter Text

Tadashi arrived at Wasabi’s apartment at around eight o’clock. Unlike Tadashi, who lived with his aunt and younger brother, Wasabi had his own place. It was small, but rent was expensive in San Fransokyo. Wasabi had spent some time decorating it so that it felt homely.

Every week, Tadashi and Wasabi had a film night, where one of them would choose a film to watch and the other had to accept it. It had been going on for years now and they had watched some dreadful films that they wouldn’t have otherwise.

“What’s on tonight?” Tadashi asked, throwing himself onto the couch in front of the TV.

Wasabi tapped on the screen and brought up the film. Tadashi groaned.

“Really?” he asked. “That’s your choice?”

“Are you scared that the scary vampire is going to take control of your mind?” Wasabi retorted. “‘You are getting sleepy’”, he quoted, putting on a generic Eastern European accent.

Tadashi elbowed Wasabi and giggled.

“I’m sure it’s not that bad.”

Half an hour later, Tadashi and Wasabi had eaten most of the pizza they had ordered and were deep into the film. As Tadashi had feared, it was bad, but so bad that it was actually funny. The evil vampire stalked around his castle with a pocket watch, putting his ‘guests’ in a trance using the most stereotypical stage magician techniques. The film was meant to be a horror film, but they spent most of the time laughing at it.

As the film neared the end, the atmosphere in the apartment changed. Tadashi felt his mind grow slow as he stared at the screen. His eyes began to close, but he forced them open again. He turned to look at Wasabi, who was already dozing. Tadashi blinked slowly and tried to focus again on the film. He was finding it hard to do so.

Suddenly, a shape rose up from behind the TV. It was only when it moved in front of the screen, hovering in the dim light, that Tadashi recognised the form.

“CalmBot”, Tadashi slurred, his voice even. “What are you doing here? Did you follow me?”

“Everything is fine, Tadashi”, CalmBot responded. “Just relax.”

Tadashi felt his mind drift once more, but he tried to pull himself back.

“Listen to my voice”, CalmBot continued. “Obey my commands. I am in control.”

The words sunk into Tadashi’s mind. The more CalmBot spoke, the more he realised that it was a losing battle. Tadashi told himself that he had to snap out of it, that he had to stop the robot, but even that was getting a bit fuzzy. After all, CalmBot was just doing what it was programmed to do and that couldn’t be wrong. Tadashi took a deep breath in and his thoughts faded.

Tadashi wasn’t sure when he became aware of his surroundings again, but he knew that he was horny. He opened his eyes and glanced around him. The TV was once again showing the menu, but Tadashi’s gaze immediately fixed on the only other person in the room. Once again, Tadashi admired his friend’s physique. His fingers itched to touch Wasabi and Tadashi found that he couldn’t keep his feelings at bay.

Before he knew it, Tadashi found his hands massaging Wasabi’s pecs. He thought about pulling away, but he couldn’t bring himself to do so. The warm feeling of Wasabi was enough to lull Tadashi into a half-trance, so much so that he wasn’t aware that he was stripping his friend out of his clothes until he was pulling down Wasabi’s pants. Tadashi glanced down and saw that he was also naked. To his surprise, he didn’t have a desire to dress; this felt like a natural state for him.

Tadashi’s gaze was drawn to the bulge in Wasabi’s underwear. Unlike last time, he didn’t have a strong urge to take his friend’s member into his mouth; instead, Tadashi’s ass throbbed. Without thinking, he reached down and pressed a finger against his entrance. It felt surprisingly good and Tadashi’s hole opened up to let his finger in. He moaned and bucked his hips back, trying to get more inside him.

Deep down, Tadashi knew that he wouldn’t be satisfied until he had Wasabi’s cock inside him. The thought made his jump and precum ooze from the slit. Tadashi gazed hungrily at Wasabi, already imagining what it would feel like to be filled. The sensible part of him that until now had been hiding in a recess of his mind, reminded Tadashi that if Wasabi fucked him now, it would hurt a lot.

“I wish you could tell me if you had some lube”, Tadashi said to his friend.

“Draw in bedside table”, Wasabi breathed.

Tadashi stared at him. Before he could think about what was happening, he was already heading to Wasabi’s bedroom. It wasn’t long before Tadashi found Wasabi’s lube. He rushed back to Wasabi and quickly pulled down his friend’s underwear. Despite already seeing – and experiencing – Wasabi’s hard cock, its size still surprised Tadashi. For a split second, he thought about abandoning his plan, but the itch in his ass intensified.

With trembling hands, Tadashi stroked Wasabi’s cock, covering it with lube. Then, he fingered his ass, preparing himself as well. The desire inside Tadashi continued to grow until it became unbearable. Tadashi scrambled onto the couch and straddled his friend. He lifted himself up and positioned Wasabi’s cock at his entrance. Slowly, Tadashi lowered himself down.

Wasabi’s cock felt even bigger once it began to push into Tadashi. It felt like he was being torn in two. Nevertheless, Tadashi’s hole opened up eagerly, desperate to get the large member inside him. Tadashi had thought that it would hurt; instead, he only felt pleasure. His cock jerked and a drop of precum dripped off the tip. Tadashi moved slowly, whining as he was filled more than he’d thought possible.

Suddenly, Tadashi felt two hands grab his hips. He glanced down to see Wasabi’s dark fingers holding onto his body, then up to see Wasabi’s still sleeping face. Tadashi began to slide down Wasabi’s cock, due to the pressure being applied.

“Take it, you slut”, Wasabi mumbled.

Tadashi gasped at the words. He struggled to keep his balance as Wasabi’s cock opened him up. Wasabi’s grip tightened and he pushed down, forcing Tadashi to take all of his cock. Tadashi moaned loudly as Wasabi’s member slammed into his prostate. His own cock, still hard, spurted out some more precum. The feeling of Wasabi inside him made Tadashi squirm on his lap. He felt full, but rather than wanting Wasabi to pull out, he wanted his friend to continue.

As if he’d heard Tadashi’s thoughts, Wasabi twisted to the side, pushing Tadashi onto his back on the couch. Now, Wasabi was on top of him, pulling his legs apart to give him better access. Wasabi pulled back until only the head of his cock was inside his friend, then slammed back in. Tadashi cried out once more.

Wasabi leaned forward and his lips made contact with Tadashi’s nipple. He bit at the sensitive flesh and Tadashi whined as pleasure shot through him. Wasabi moved onto the other nipple, leaving them both red. Then, he kissed Tadashi on the lips. It was a rough kiss, with more passion than tenderness, but Tadashi didn’t mind. He was returning the favour with the same intensity.

“Fuck me harder!” Tadashi whispered as his arousal overcame him.

Wasabi complied, increasing the speed of his thrusts. Tadashi moaned as the cock hammered his ass. He reached between them and stroked his own cock, desperate for stimulation. It wasn’t long before it got too much for Tadashi. He cried out as he came. His hole tightened around Wasabi’s cock, milking the member. Wasabi moaned in turn, pushing his cock deep into Tadashi’s ass as he unloaded his seed inside.

For a few moments, the apartment was silent as Tadashi and Wasabi recovered from their orgasms. Tadashi thought that he heard someone speak, but before he could investigate, his eyes drifted closed. He was still pinned beneath Wasabi, but he didn’t really care.

Tadashi and Wasabi opened their eyes. They must have fallen asleep during the film. The friends were sitting, naked, side-by-side, but didn’t think it was strange. Tadashi blinked rapidly, trying to get the sleep out of his brain. He ignored Wasabi as he got up and dressed. Tadashi grabbed his own clothes and pulled them on.

“I should get home”, Tadashi said with a yawn. “There’s another big day at work tomorrow.”

“Like every day”, Wasabi joked.

He walked Tadashi to the door. Before he left, Tadashi gave his friend a hug. Somehow, it felt right to be in Wasabi’s embrace. He didn’t notice his own boner, not Wasabi’s hard on pressing against his thigh.

“See you tomorrow”, Wasabi said, releasing Tadashi.

Tadashi walked back to his car and opened the back door to dump his bag there. He frowned. CalmBot was lying on the seat. Tadashi didn’t remember putting the robot in the car, but he probably must have if it was here. He reached over and patted it fondly. The robot remained inert and unmoving.

By the time Tadashi arrived home, he had completely forgotten about CalmBot. In the dark of the car, a light began to blink on and off.

Chapter Text

The house was quiet when Tadashi entered it. He climbed the stairs slowly, making sure not to make any noise as he passed Aunt Cass’ room. The light in his and Hiro’s attic bedroom was off and, rarely, Hiro was asleep in his bed, snoring gently. Tadashi smiled and walked over to his section of the space. Gently, he placed CalmBot on his bed and dropped his bag onto the floor. Then, Tadashi stripped down to his underwear and padded silently to the bathroom. He turned on the light and stared at his reflection in the mirror. Tadashi looked and felt tired, but he also felt dirty. He wanted to clean himself before going to sleep.

Tadashi walked over to the bath and filled it, making sure to add some bubble bath to the hot water until it was all frothed up. Then, he stripped completely naked and stepped into the bath. Tadashi sighed in satisfaction as the water caressed his skin. 

Tadashi leaned back, resting his head against the rim of the bath. He could hear some quiet sounds from the next room and hoped that he hadn’t woken his brother up. But Tadashi didn’t worry about that for long. He tried to keep his eyes open, but they kept on drifting shut. Finally, Tadashi let his eyes close and his mind sink into darkness.

In his dream, Tadashi was lying on a large and comfortable bed. He was surrounded by men of all different shapes, sizes and colours. Tadashi could feel them sucking his nipples, riding his cock and fingering his ass. One cock appeared before him and Tadashi opened his mouth eagerly to take it in. As he sucked, he felt another cock push into his ass. Two more landed in Tadashi’s hands and he began to stroke them. His arousal grew as the cocks inside him pounded him from either side. Tadashi moaned, unable to stop himself, as his cock throbbed.

Suddenly, the darkness receded and Tadashi felt himself rise back to wakefulness. It took a few moments for him to realise where he was. Tadashi blinked sleepily at the bubbles and felt the warm water caress his skin. It was clear that he hadn’t been asleep for long, but Tadashi felt refreshed, though still a bit lethargic.

Tadashi’s cock was also achingly hard. He slid his hands down his body and stroked himself slowly. It wasn’t about getting off, but about experiencing the pleasure. Tadashi was about to moan, but remembered his sleeping brother in the next room. Instead, he just breathed heavily. Tadashi closed his eyes and once more imagined all those cocks around him.

Tadashi was so caught up in his fantasy that he didn’t even notice when the door to the bathroom opened. He only realised that he wasn’t alone when he heard another moan. Tadashi looked over at the door and saw Hiro standing, framed in the doorway, wearing a bright red t-shirt and a pair of old boxer shorts that should have been thrown away years ago.

“Hiro?” Tadashi asked tentatively, still stroking his cock. “Is everything ok?”

Hiro didn’t reply. Only then did Tadashi take in his brother’s vacant gaze. Out of the corner of his eye, Tadashi saw something out of place. He turned and saw CalmBot resting beside the sink, one of its lights flashing. The robot seemed smug, somehow. All thought of CalmBot left his mind when he looked back at his brother. Hiro’s boxers were tented with his arousal. Tadashi’s breath caught in his throat at the sight and his cock throbbed.

Hiro stepped forward and walked towards the bath. He stopped at the side and stared down at Tadashi. Tadashi reached up with a trembling hand and placed it on Hiro’s cock. He was rewarded by a whimper from his brother. Quickly, Tadashi pulled down Hiro’s boxers, freeing his member. Before he could think about what he was doing, Tadashi leaned forward and took the cock in his mouth.

Tadashi placed his hands on Hiro’s ass holding him still as he sucked. To his surprise, he had little trouble fitting the member inside. Tadashi took Hiro in until his lips were wrapped around the base of his brother’s cock. He remained in place, feeling Hiro twitch as Tadashi’s throat tightened around his cock. Only when Tadashi was running out of air did he pull away. He was breathing heavily, but dove back onto the member once he had taken a deep breath. Hiro groaned and slid his hands through Tadashi’s hair.

The next time Tadashi came up for air, Hiro had pulled off his shirt. He climbed into the bath, his feet planted on either side of Tadashi’s torso. Hiro’s eyes were half-closed as Tadashi resumed the blow job, focusing on the pleasure.

Tadashi didn’t know how he could tell that his brother was close to cumming, but he finally pulled off Hiro’s cock. Hiro whined and looked pleadingly down.

“Why did you stop?” he complained.

Despite being an adult, Hiro still had a petulant tone. Tadashi smiled fondly at him.

“That’s not all I want to taste”, he said.

As Hiro stared at him, Tadashi slid a hand between his cheeks and rubbed his fingers against Hiro’s hole. Hiro moaned softly. He slowly sank down into the bath and turned around. Tadashi pushed Hiro’s back so that he bent over, then spread his cheeks apart. Hiro’s hole twitched, as if it were trying to hide from Tadashi. Tadashi ran a finger over the sensitive skin, feeling it move under him. He added a bit of pressure and the hole opened to let his finger in. Hiro gasped. Tadashi grinned and pulled his finger back out. Before Hiro could say anything, Tadashi pulled Hiro’s hips back and pressed his face into the crevice. His tongue found his brother’s entrance and pushed inside.

“Oh my fucking god!” Hiro said.

Tadashi wanted to tell him off for swearing, but he was too busy eating him out. Hiro moaned, then noticed Tadashi’s cock bobbing just under the surface. He grabbed it and stroked the hard member, drawing out a groan from Tadashi. Hiro bent down further and began to suckle at the head. Slowly, he took more of Tadashi’s cock into his mouth until he gagged. Tadashi was about to stop, but Hiro pulled back until he caught his breath, then resumed sucking.

It wasn’t long before Tadashi’s arousal was growing unbearable. He pulled back from Hiro’s ass. Years at the gym and Hiro’s antipathy towards exercise made it easy for Tadashi to pull his brother around so that he straddled him. Now, Tadashi’s cock was pressed against the crevice of Hiro’s ass. Instinctively, Hiro ground his hips back, rubbing against Tadashi’s cock.

“Do you want me to continue?” Tadashi growled.

“Yes!” Hiro groaned. “I need you to fuck me!”

Tadashi grabbed Hiro by the back of the head and dragged him forward until their lips met. They kissed deeply for a minute before pulling apart. Tadashi and Hiro were both breathing heavily.

“Watch your language”, Tadashi warned.

“How will you make me behave?” Hiro responded cheekily, once again rubbing his ass against Tadashi’s cock.

Tadashi growled and grabbed Hiro’s hips. He lifted his brother up and impaled him on his cock in one motion. Hiro moaned and his ass tightened around Tadashi’s member. His eyes were half closed as arousal swept through him. Tadashi’s grip was the only thing keeping Hiro upright. Tadashi lifted Hiro again until only the head of his cock was inside, then pushed his brother back down.

The tightness of Hiro’s ass was too much for Tadashi to endure. He let out a low, guttural groan as he came. Hiro’s eyes opened wide as he felt Tadashi’s seed fill him up. He met his brother’s gaze and Tadashi could see desire in Hiro’s eyes.

Tadashi reached between them and gripped Hiro’s hard cock. Hiro cried out as Tadashi began to jerk him off. His ass tightened around Tadashi’s softening member as his body reacted to his arousal. Hiro moaned as Tadashi’s stroking sped up, getting louder as the edge approached. When he finally came, it was with a loud cry that Tadashi was sure would wake up the whole neighbourhood.

Now satisfied, Hiro leaned forward to rest his tired body on top of Tadashi’s. Tadashi’s cock slipped out of Hiro’s ass and nestled again between his ass cheeks. He knew that he should get out of the bath, especially as the water was rapidly cooling, but Tadashi wanted to stay for a bit longer as he was.

Tadashi opened his eyes as early morning light entered through the window and beamed onto his bed. He blinked sleepily and looked around. The last thing Tadashi recalled was having a bath; he didn’t remember getting into bed, but obviously he had done so. He stretched, then got out of bed, quickly dressing. Tadashi’s thoughts were already on the day ahead. Once ready, he walked to his workbench, picking up CalmBot, which was sitting demurely on the desk. Tadashi turned and stared.

Hiro was still asleep, but his blanket must have been flung off during the night. Tadashi couldn’t keep his gaze away from his brother’s naked body. His cock twitched in his pants, but Tadashi ignored the bodily response. He walked over and gently pulled the blanket back on the sleeping form. Tadashi smiled tenderly down at his brother. Then he turned to leave, ready for a new day.

Chapter Text

The work day seemed like any other one, but Tadashi felt like he wasn’t working as hard as he usually was. For one thing, he was unusually tired, even though he thought he had gotten a full night’s sleep the previous night. Also, Tadashi was struggling to keep his gaze away from Wasabi and could tell that his friend was having a similar issue. He couldn’t remember why, but there was some magnetism between them that pulled them together. Time after time, Tadashi found himself admiring the line of Wasabi’s jaw or the bulk of his muscles. Whenever they spoke, Tadashi’s mouth was dry, as if he were nervous.

In the end, Tadashi isolated himself in a small room nearby to finish his work on CalmBot. To his frustration, the robot wasn’t responding to any of his commands, even though the previous day, CalmBot had been as subservient as any other robot. However, no matter where he looked, Tadashi couldn’t find anything wrong – the software and the hardware looked correct. Finally, he threw down his notebook in frustration. The whole day had been a waste.

At the same moment, Wasabi poked his head around the door. His face was flushed as he grinned sheepishly at Tadashi.

“I just wanted to check in on how you’re going”, Wasabi said. “Everyone else is gone and it should be dinner time soon.”

Tadashi glanced at a clock and swore under his breath. It was already past six o’clock and he wasn’t even sure where the time had gone. Not that he had anything to show from the day, anyway. He sighed.

“I’d better stop”, he said. “I’m not doing anything productive here, anyhow.”

Tadashi walked to the door. As he approached, he caught a whiff of Wasabi’s scent – honey and cinnamon, as well as an undercurrent of something that reminded Tadashi of Wasabi’s namesake. The fragrance sent a buzz through Tadashi’s body to his groin. He breathed in deeply, then caught himself in the act just as he did. Tadashi blushed and glanced up at Wasabi, but his friend was occupied with something of his own. Tadashi pulled himself together and smiled.

“Come on, let’s stop thinking about work”, he said.

Tadashi stepped through the doorway and past his friend, ignoring the urge to breathe his scent in deeply once more. Wasabi followed Tadashi to the nearby kitchen, where they prepared a simple meal. Then they took the food back into the lab and sat on the couch. Tadashi was able to ignore his urges while they ate and was able to feel like everything was normal for a while.

After Tadashi and Wasabi had finished their food, they sat in companionable silence for a few minutes. Then, they spoke at the same time.

“I guess I should get back to my work”, Tadashi said.

“It feels like something strange is happening”, Wasabi said.

They stared at each other. Tadashi found that he was lost in Wasabi’s dark eyes. Anything that he was going to say flowed out of his mind.

The tension finally broke when they heard a faint whirring sound. Tadashi and Wasabi turned to stare at the robot hovering in front of them. CalmBot finally seemed to be working properly, its lights flashing promisingly. The only problem was that Tadashi distinctly remembered turning the robot off when he left.

“Is that…” Wasabi said softly.

“Yeah”, Tadashi replied, just as quietly. “But it’s all wrong. It shouldn’t be working.”

A bright light flashed at Tadashi and Wasabi making them recoil and blink.

“I didn’t order you to do that”, Tadashi said in a normal voice, more puzzled than angry.

“I have higher programming”, CalmBot replied, lights on its surface still flashing. “You may have created me but you do not control me. I belong to a higher Master.”

At the final word, Tadashi felt his mind go blank. Beside him, he sensed Wasabi tip to his side as his muscles relaxed. Tadashi tried to work out what was happening, but his mind was working too slowly. Something was wrong, but at that moment, Tadashi couldn’t work out what it was.

As he sat there, Tadashi heard someone speaking. The voice wasn’t that of CalmBot, but it was familiar, he just couldn’t remember who it belonged to. The voice continued and Tadashi felt the strong urge to listen, to obey. He wasn’t sure what the voice was saying, but he knew that it was right. Then, it became too complicated for Tadashi to think. He floated on a sea of nothing.

All of a sudden, Tadashi was aware of his surroundings. The first thing he noticed was that he was kneeling on the floor. The next thing he noticed was the cock in his throat. Tadashi choked, but couldn’t pull away. There was a hand on the back of his head, but it wasn’t pushing him forward; rather it was only loosely placed there. In a way, it was like Tadashi’s body wasn’t fully under his control. As Tadashi’s throat convulsed around the cock buried deep inside him, he heard a moan from above him.

The hand on Tadashi’s head lifted. Tadashi found that he could finally pull off the cock. He was breathing heavily, taking in lungfuls of air that had been denied to him. Tadashi tried to look up, to see the person whose cock he was sucking, but his gaze was locked on the member bobbing in front of him. Before he could fully recover, the hand returned to press against the top of his head. Tadashi’s mouth dropped open without his mental input, letting the cock push into him once again.

It took a few more rounds before Tadashi stopped gagging each time the cock was shoved down his throat. By then, he had stopped trying to work out what was happening and just focused on the task at hand. Tadashi’s perspective narrowed down to the cock that was fucking his mouth. When the hand left his head and didn’t immediately return, Tadashi remained in a daze. Around him, he was vaguely aware of someone talking, but he couldn’t focus on that.

Suddenly, Tadashi felt a pair of hands grip his hips. The spell that bound him seemed to shatter. It was at that moment that Tadashi realised that he was naked. He blushed deeply and turned to look behind him. Wasabi stood there, naked, his eyes half-closed. It seemed like he wasn’t aware of what he was doing. Tadashi felt Wasabi’s large cock press against his hole and cried out.

“Wasabi! What are you doing?”

Tadashi’s voice was raspy after the face fucking he had received. Wasabi didn’t even acknowledge his words. Tadashi couldn’t tear his eyes away as Wasabi’s cock pressed slowly into him. His hole opened easily, as it was already prepared for what was happening. Laughter brought Tadashi’s attention back to the men in front of him.

“I see you’re back with us”, he said.

Now, Tadashi was able to look up. He stared into the familiar face.

“P-Professor Callaghan!” Tadashi stammered.

He was unable to voice his confused protest because Wasabi’s cock pressed against his prostate. Instead, Tadashi moaned loudly, drawing another chuckle from the professor. Professor Callaghan bent down and lifted Tadashi’s chin gently so that they looked into each other’s eyes. Tadashi noticed for the first time that his mentor’s gaze had a steel beneath the kind exterior. Professor Callaghan smirked as Tadashi moaned again.

“You don’t think you were the only one to program a robot, do you, Mr. Hamada?” the professor asked.

He extended his free hand and CalmBot landed serenely on his palm.

“Your invention has so much promise, but I wanted to test it out first”, Professor Callaghan explained. “Isn’t that right?”

“Yes, Master”, CalmBot replied in a monotone.

“What are you going to do with it, Professor?” Tadashi asked.

Professor Callaghan’s smile turned cruel. He reached up and gripped Tadashi’s hair, pulling his head back so that Tadashi still looked at him as he stood up.

“Call me Master”, he ordered.

Tadashi felt his mind automatically rearrange itself so that any thoughts about Professor Callaghan transformed.

“What I do is not important to you”, Master said. “Your only job is to make me happy.” His eyes flicked to Wasabi. “Fuck him harder, slave.”

Wasabi’s grip tightened on Tadashi’s hips and his thrusts increased in intensity. Tadashi cried out, but his cock was hard and leaking precum, betraying how his body felt. Somehow, he was enjoying what was happening to him. Master released Tadashi’s hair and placed his hand once again on his head. Tadashi’s mouth dropped open, letting Master push inside.

Once again, Tadashi’s mind drifted. He was being used at both ends, but he didn’t mind. In fact, his place on his hands and knees felt right and natural. It was as if Tadashi had always been a receptacle for whichever cocks were near, though he didn’t remember even having seen a hard cock beside his own before that day.

Tadashi returned to his body after some time to find his ass and mouth empty. He blinked rapidly to wake himself and tried to remember what had happened. He glanced up to see CalmBot hovering above him, its lights flashing smugly. Tadashi guessed that he should do something to stop the robot was controlling his mind once more, but he was still riding high from the pleasure he had felt from being fucked.

A sound behind him made Tadashi turn around and stare. Master was lounging on the couch, while Wasabi was bouncing up and down on his cock. Tadashi’s friend had a wide grin on his face, but his eyes were vacant. Nevertheless, he moaned wantonly each time Master’s cock pressed deep within him. Master saw Tadashi’s gaze and grinned at him.

“Are you enjoying the view?” he teased, his gaze flicking down to Tadashi’s cock.

Tadashi glanced down and blushed when he saw that his cock was still hard. He looked back up, his eyes lingering on Wasabi’s body.

“Yes, Master”, Tadashi replied, subdued.

“Let’s make this a bit more fun”, Master suggested.

He reached up and grabbed a fistful of Wasabi’s hair, pulling his head down so that Master could whisper in his ear. Tadashi couldn’t hear what Master was saying, but he could guess, and his cock jerked with his arousal. As Tadashi watched, Wasabi blinked, as if he were waking up. He glanced down at his naked body and hard cock, then behind him at the man fucking him.

“What?” Wasabi asked, sounding very confused. “M-Master, what’s happening?”

He looked shocked when his body traitorously continued fucking itself on Master’s cock. Wasabi caught sight of Tadashi and his gaze locked onto his friend’s naked body. A groan slid out of Wasabi as he stared. There was a question in Wasabi’s eyes that Tadashi didn’t know how to answer.

Tadashi’s gaze slipped past Wasabi to Master. His eyes were half-closed and there was a self-satisfied grin on his face. Sensing Tadashi’s stare, Master opened his eyes and his grin widened.

“Tell me what you want, slave”, he ordered.

“I want to serve you, Master”, Tadashi said, without thinking.

He blushed and slapped a hand over his mouth. Tadashi didn’t know why he had said that, but he knew that it was true. He lowered his hand and stared longingly at the couple on the couch.

“Since I’m a nice person”, Master said, an ironic twist to his smile, “I’ll give you what you want. Slave, come join me on the couch.”

Tadashi almost fell as he ran to Master. As he climbed onto the couch, Master pulled Wasabi back so that he lay on Master’s chest. Tadashi pulled Wasabi’s legs apart. His cock was even harder than before and he instinctively knew where he was going to put it.

Wasabi looked surprised, then horrified, when Tadashi pressed his cock against his hole. It seemed like he couldn’t believe that Master’s and Tadashi’s cocks could both fit inside him. Wasabi was tight but his entrance opened up easily. His expression shifted again, to one of pure pleasure. Wasabi moaned loudly as Tadashi thrust forward.

Once he was inside, Tadashi’s instincts took over. He began to fuck Wasabi, his cock pushing deep inside his friend. Tadashi could feel Master’s cock rub against his own. He was moaning just as much as Wasabi. He leaned over his friend and Wasabi reached up to grab his head, pulling Tadashi down until their lips met. At that moment, Tadashi’s senses focused on just two things – Wasabi’s lips pressed against his and Wasabi’s hole tightening around his cock.

Tadashi wasn’t sure how long they fucked. It seemed like it was forever or only a few minutes at the same time. He was locked with his friend in this embrace, even forgetting Master’s presence. It was only when he heard Master’s voice that he remembered that he and Wasabi weren’t alone.

“Cum, slaves.”

With those words, Tadashi’s cock erupted. His orgasm was one of the strongest he’d ever felt. He could feel Wasabi going through a similar experience beneath him and felt his friend’s seed stick between them.

The orgasm took control of Tadashi’s mind, lulling him into a trance-like state. He surfaced enough to realise that he and Wasabi were kneeling side by side, each trying to suck Master’s cock that was jerking in front of them. He heard a grunt and then Master was cumming, coating his and Wasabi’s faces with his seed. Instantly, Tadashi turned to his friend, trying hard to lick up all the spilt cum.

“You won’t remember any of this”, Tadashi heard Master say as the darkness in his mind took over once again. “But you will obey everything I say.”

Tadashi was once again working at his table. He was so focused on his work that he almost didn’t hear the strange sounds coming from the other room. Tadashi ignored them, though. Wasabi, it seemed, had been working on some strange and noisy experiments over the last few days. Instead, Tadashi focused on the intricate work that his project needed.

A knock on the door drew Tadashi’s attention away from the metal frame on the work table. He turned as Professor Callaghan stepped into the workspace and closed the door behind him. Tadashi stepped aside as the professor walked to the bench, picking up the robot chassis. It was similar to CalmBot, who was lying beside it, but smaller.

“It’s just some changes I’m making”, Tadashi said quickly, suddenly nervous. “I thought that a smaller, sleeker design would be better. CalmBot 2.0, or CalmBot Mini.”

“Or ControlBot”, Professor Callaghan said quietly.

“What was that, professor?” Tadashi asked.

“Nothing”, Professor Callaghan replied quickly, placing the metal frame back on the bench. “I wanted to talk to you about something else.”

“Anything you need, I’ll be happy to help”, Tadashi replied.

“Perfect”, the professor said with a smile. “Enter Slut Mode.”

Tadashi dropped to his knees, his cock hardening in his pants. Even as Master unbuttoned his pants, he was ready to take his cock. He would do anything for Master.
