A little known fact about Sonic was how he hated being cold. That wasn’t an issue while he was running, the constant motion naturally kept him warm even if it was cold outside, but on the odd day off and if the blue hedgehog stayed inside he was bound to complain at some point or another about feeling chilly.

He would normally remedy it on his own with blankets or clothes, which was much better than him adjusting the air conditioning without saying anything, but it was shocking when one day Shadow had seen his partner walking around in full fleece pajamas while it was hot and humid as hell outside.

The hybrid would never complain about it though, because these days inside meant Sonic was snuggly, somewhat silent, and sleepy. It had to be his body’s way of recharging after constantly burning energy and only getting an average amount of sleep each night, frequent naps were much better than the hero keeling over from exhaustion.

So Shadow would always welcome Sonic crawling into his lap and closing his eyes for a few minutes or all day, shifting between being half-awake or asleep while purring or making half-aborted snores and hums as he dreamed, and today was no different.

Sonic had been napping all afternoon as Shadow got absorbed into watching a show about how different products and items were created or mass-produced. His head was nestled in the hybrid’s lap, nose buried into his stomach, and lightly purring at the hand Shadow was petting over his side all while beneath a quilt. Falling into a routine like this would have made the Ultimate Lifeform scoff in his younger years, the idea of domesticity and love more than enough to make him scowl back then, but now it was one of many small creature comforts that the hybrid didn’t want to live without in his older years.

Below Shadow he heard his boyfriend’s breathing change ever so slightly, and it was no surprise when the other suddenly shifted around as he stretched with a loud yawn,

“You still watchin’ tha’ show?”

Shadow hummed in reply without looking from the TV, moving his hand from being on top of the blanket to underneath it to lay on a warm hip as his thumb edged underneath the hoodie Sonic was wearing. How the other could stand that, long pajama bottoms, and a thick blanket was beyond him.

“Mmm. Wha’s been your fave one?”

“Nothing in particular, but there’s been a few about wood-working I’ve liked.”

Slowly that thumb was joined by a few fingers, and then his whole hand. Sonic gave no protest or pushed it away, which was all the permission Shadow needed to continue his wandering. He wasn’t a stranger to his boyfriend’s body, but it was something else on lazy days like this.

Underneath the oversized clothes Sonic wore, his lean body became soft and pliable from the warmth of sleep. His fur turned velvety beneath Shadow’s paw pads, and running over the other’s waist made the hero’s breath hitch while a pleased hum left his throat. The hybrid glanced down to see Sonic’s eyes still shut, and slowly began to move closer to what he really wanted beneath his hand, waiting to see the reaction it would cause.

His palm finally slid over a small, warm breast, a thumb automatically swiping out to tease at a soft nipple. Sonic shuddered before curling his chest in towards the touch, eyelids opening just enough for emerald eyes to shine at him as he aimed a knowing smirk up at Shadow.

“Looks like you’ve found something better to do now though?”

The hybrid sent his own smirk back, relishing Sonic’s soft sigh as he squeezed the handful he had. Ideally his other hand would be fondling his boyfriend’s other tit, but their current position didn’t allow it, so he made do with bringing it up to rub a blue ear. It was enough for the other to start purring while leaning into both touches and the area of the blanket just behind him to start moving as his tail wagged beneath it.

“What can I say? I prefer to see you react to my hands than watch anything else.”

Sonic gave a soft laugh that turned into a moan as Shadow’s fingers teased at a now hardened nipple, slow circles with his thumb before his pointer moved closer to gently grab and tug on it. His hips shifted beneath the blanket, and reminded Shadow of another spot he could be exploring right now.

It was cute how quickly Sonic began to pout as the hybrid swapped his hands around, although once Shadow’s left hand was in place while his right moved down, it was replaced with a needy whine.

He dipped past the waistband of Sonic’s bottoms, not surprised to find the other already growing wet, but was confused as his fingertips brushed against not his partner’s entrance, but warm and slick silicone. The action pulled a chuckle from the blue hedgehog, Shadow able to feel the movement from where his hand laid over his chest.

“Sorry Shads, looks like I was a couple steps ahead of you.”

Shadow rolled his eyes as Sonic continued to snicker, the laughter quickly changing into a moan as fingers circled around the base of the toy inside the hero, the silicone shifting as the hedgehog clenched down onto it from his touch.

“I think I could have come to that conclusion on my own. What made you want to put this in, and how long have you had it in?”

“Who said I hafta tell ya any of that?”

The hybrid raised an eyebrow, grasping the base of the plug, “Fine, be that way.” He pressed down on the toy, causing the hedgehog on his lap to shudder as it no doubt bumped against the sensitive spots inside of him. Shadow did know the reason why and could guess how long, wishing he had more than toys to give Sonic what he wanted or had caught onto what the hero was doing earlier before he settled down to nap, regardless of that teasing the other was an opportunity he could never pass up.

The position wasn’t the easiest on his arms, but Shadow kept playing with Sonic’s body to watch him slowly fall apart. Every pant and moan, each shudder and twitch, his boyfriend put on a show better than anything that could be found on TV. Eventually Sonic moved onto his back, one hand grabbing at the arm that was currently thrusting the plug in and out of him, and the other joined the hand beneath his hoodie to knead and massage his neglected pec. Sonic’s squirms and pinched eyebrows stoked the fire burning in Shadow’s own gut, driving him to lean down and catch the hero’s open mouth in a kiss, feeling the other’s hand leave his arm to dig into his quills and tilt their heads for a better angle.

All it took was a firm pinch on a nipple and pushing the toy all the way back into Sonic to make him finally lose it, feeling a whine vibrate against his lips as thighs clamped down on Shadow’s hand that rubbed quick strokes over the blue hedgehog’s dick, hips bucking as the orgasm the hybrid had brought him up to crashed over him. Only after it was done did Sonic loosen his hold on Shadow, his hand dropping down to the couch and his legs falling open, letting out a content sigh as they broke their heated kiss.

He could have kept his hand on his boyfriend’s pussy the rest of the day, to feel each twitch of the plug as Sonic pulsed around it and tease that cock until he begged him to stop, but with newly slick fingers Shadow moved his right hand back to where it started to rub against a perked nipple. It made the hedgehog in his lap moan and blue eyelids close, a satisfied smile on Sonic’s face as he rode the waves of his post-orgasm.

Days like this were few and far between, having the hero take it easy when he wasn’t busy with badniks to destroy or a public to perform for. He was more than happy to just have Sonic sleep away while within his arms, however, Shadow would never pass up an opportunity to have his partner’s body pliable, open, and responsive to his hands and his alone.

Despite his best efforts to come across as a serious, stoic kind of hedgehog, Sonic could only look at Shadow and think about the small quirks that broke the image he portrayed to the world.

His preference for the scent of lavender as well as having a soft spot for cats and wanting to run a rescue for them one day fought against Shadow’s intimidating demeanor. There was one other thing, but rather than evoke warm, cozy feelings out of the blue hedgehog, it riled him up.

Whether it was a requirement of G.U.N. or an actual thing the Ultimate Lifeform chose of his own free will, Shadow had a dedicated workout outfit. It was nothing special, nor looked to be regulated by who he worked for; it was just a simple white tank top and red athletic shorts. Sonic only occasionally caught glimpses of the hybrid wearing it, mainly when Team Dark had weeks between missions and presumably had group workouts to keep in top form, but that just made it all the better when he did get blessed with the sight of his boyfriend in this unreasonably provocative outfit.

Today while walking back into their shared home after an evening sprint, Sonic had one of these rare sightings, catching Shadow wearing the outfit as  he stood at the kitchen sink.

The red fabric of the shorts hugged the subtle curve of Shadow’s hips, the stitching on the outside framing his ass and tail in a way that made Sonic’s hands itch to grab or pull, and from memory he knew how the top of the shorts cinched in the other hedgehog’s waist that was currently covered by a sweat-soaked and almost see-through white tank top.

Even with the other’s back turned to him, black and red quilled head leaned back to chug a glass of water, Sonic could easily picture what Shadow’s front looked like. Damp fabric clinging to a dark torso, mussed white fluff poking out through the top of the neckline, and arm holes wide enough that allowed one to see the slight curve of the Ultimate Lifeforms chest.

There was only one logical course of action for Sonic after coming across such a sight, and that was to cross the apartment in milliseconds to press up against his sexy boyfriend’s back, and act on what these simple clothes did to his one-track mind.

His mouth latched onto an exposed neck as his arms wrapped around Shadow’s body, one hand grabbing at his waist to play with the top of the shorts as the other began to slide up and over fabric that covered his chest, causing the hybrid in Sonic’s arms to ever so slightly flinch and let out a grunt as he set his glass down. The blue hedgehog couldn’t keep from grinning while he sucked at sweat-tinged fur as Shadow sighed, his own hands laying over where Sonic’s were on his body,

“You really couldn’t even say hello first?”

Sonic lifted his lips up enough to respond, still grinning wide as he spoke,

“You really don’t see how hot you look in these clothes?”

Shadow huffed at that, shifting on his feet and sighing again as Sonic tucked fingers under the waistband of Shadow’s shorts and a hand grabbed at his chest,

“Can’t we do this in the shower, that way we both don’t smell like a gym bench?”

“Nope.”

Sonic turned Shadow around, pulling him into a kiss as his fingers pulled at the clothing until the hybrid was completely exposed, white chest fluff mussed down while the tanktop framed Shadow’s tits and the engorged bud of his cock poked out past the dark fur on his crotch.

The huff of resignation Shadow pushed through his nose was immediately covered with a soft moan as Sonic’s gloved fingers began to take advantage of the other’s revealed body, one hand cupping and squeezing a tit and the other bypassing the waiting cock to press into the slick hole just beneath it. 

After a second of Shadow trying to widen his stance to accommodate Sonic’s hand and failing because of the red shorts still around his thighs, he grunted and pushed the blue hedgehog back just enough to finish shoving the clothing all the way down, their kiss breaking for ruby eyes to glare at emerald ones,

“Ten minutes from now I will be getting in the shower, and if you want to join me for it, you better finish me off in the next nine.”

The hero chuckled at the words, pressing his boyfriend back against the counter and sending him a determined grin,

“Betcha I can do it in five.”

The hand Sonic was holding the hybrid’s chest with moved to instead grab and lift up a striped leg, creating ample space for his other hand to quickly thrust fingers in and out of Shadow with ease, and leaned his head down to tease and lick at the neglected nipples instead. Blue ears perked up at the sound of soft panting, the warmth in Sonic’s core stoked higher at the delicate sound. 

He sped his thrusting fingers up, switching from aimless prodding to a more focused come hither motion right against that spot that made Shadow shudder, scraping his teeth and prodding his tongue over hardened nipples and sucking on soft fur. A hand buried itself into Sonic’s quills, forcing his head closer to Shadow’s chest as black-furred hips canted onto his fingers, causing slick to drip down off his knuckles and onto the abandoned shorts on the floor.

”Damn, you’re really wet despite being grumpy about being felt up and claiming you smell-“

”Shut up and finish what you started asshole!”

Sonic snickered and doubled his efforts, his hand nearly becoming a blur between Shadow’s legs and sucking a hickey onto the side of his left tit. The hybrid held on tight, hips continuing to rock against Sonic’s hand as his panting turned into bitten off moans.

“ Ah-Almost-fuck Sonic I’m almost-!”

Three fingers and a thumb on Shadow’s cock did him in, the Ultimate Lifeform crushing Sonic close to him as he rode out his orgasm, the blue hedgehog grunting at the tight hold but grinning as he felt and heard a gush of fluid run over his hand and hit the floor.

Sonic finally pulled his mouth off of Shadow’s chest and pulled his boyfriend into a kiss, one that was slower and softer compared to the frantic energy of the past few minutes. Shadow relaxed into Sonic, pressing his nose into Sonic’s neck and humming in content as he was lifted by the other to be carried.

“I’ll be generous and say you did it in six.”

“Babe I know I made you cum in five.”

“Fine. You’re cleaning up the mess you made.”

“Okaaaaay. . . although, if we’re talking about the one who truly made the mess by being the source-“

Sonic chuckled at the kick of Shadow’s heel on his ass to stop his sentence, dropping it in favor of relishing his boyfriend relaxing further into him. He’d do as was requested of him, but not before Sonic spent quality cuddle time with Shadow in a warm bath. Not that it wasn’t rare for the Ultimate Lifeform to be lax and affectionate like this with him, but because Sonic was the only one to see Shadow in this way, no different than any other being on this planet.
