#he (begrudgingly) coexists with everyone else and behaves lmao

[sukugo]

sukuna and gojo use binding vows for sex, taking things like orgasm denials or touch deprivation steps further, where the other is contractually bound to not be able to do certain things, like touch themselves or touch the other etc etc 

one such instance being a vow where gojo has a vibrator up his ass, but he can't touch himself or remove it, until sukuna specifically, pulls it out.  

he keeps the vibe in throughout the day, with sukuna controlling it remotely, even as they both go throughout their separate days.  

gojo goes to have his usual breakfast, and meets yuuji at the dining room, they greet and sit next to each other. yuuji is, as always, energetic and excited to see him 

they make conversation, until gojo gives a jolt and starts twitching and huffing. sukuna has turned the vibrator up all the way. yuuji worries and panics and asks him what's wrong. gojo gives a breathy laugh and reassures him. he motions low and tells yuuji about the vibrator inside him, through sudden jolts and soft whimpers.  

satoru complains about it, and yuuji advices to remove it or go and take care of himself.  

except gojo states that he can’t and yuuji puzzles.  

"it's... a pact—mmh!" 

"a pact???" yuuji's voice rises in volume, but he visibly calms, shoulders dropping into a fond sigh. "sensei, you really are..." that's all he can manage to say. reprimand is useless. gojo likes it, yuuji is well aware, he is enjoying every second of this, even as he complains.  

gojo gives a few odd jolts, undoubtedly an odd pattern of intensity from the vibe, yuuji can guess. sudden irregular ups and downs that are not taken well by the man.  

satoru clicks his tongue. "what is that guy doing?" he actually looks irritated for a moment—a look yuuji doesn’t get to see often—until it’s broken with a sigh and his pleased, calm demeanor returns, mimicking the soft waves of pleasure across his thighs. 

still, yuuji can see his hands crumpled at his sides, undoubtedly wishing to use them.  

that's when satoru perks flares up all of a sudden.  

"actually, yuuji,” he turns to look at him, grinning. “you can help me" he opens his legs and lifts the edges of his kimono, his dick peeking out the fabric. yuuji gulps at the sight. satoru motions to it, giving yuuji a wordless look. yuuji hesitates for a moment, but complies, taking his hand to the cock, and starts stroking. 

satoru crumbles under the touch, immediately breathing out his nose and muffling moans. he leans into yuuji, wrapping an arm around his shoulders, fingers clasped in yuuji's kimono, nuzzling into his hair and whining in his ear.  

satoru's sounds fluctuate in pitch and volume, making it known when his vibe's gotten stronger. yuuji keeps his pace and satoru spills in his hand. he twitches and sighs, soft breaths against yuuji's flushed ear. 

yuuji stares at the cum in his hand.  

"you can wipe it on me,” satoru tells him with a breath that's calmed much too fast. “my clothes are already soiled anyways". and yuuji feels bad for it, but he obeys nonetheless.  

satoru takes a hand to yuuji's chin and turns his face to him and gives him a kiss. short and sweet.  

"as a reward." he smiles at yuuji. the boy surprises but takes it happily, cheeks warm and eyes softened, albeit a bit timidly. a tinge of disappointment colors the edges of his face. 

"you want more?" satoru brings his face to yuuji's again. the vibrations have reached a slight plateau, so his voice is steadier.  

yuuji’s face widens a bit, but he nervously chuckles, pulling back from gojo's face. "no, it's alright," he lies. "i don't want sukuna to kill me" 

but satoru’s already pulling into him, breathing into his lips. "i won't let him <3"

"that's...actually reassuring......" yuuji’s eyes flutter shut as satoru's lips meet his again.  

and with that, they're kissing and slowly the vibrations and gojo’s twitching start again. satoru moves atop yuuji's lap to straddle him, and while they kiss, yuuji takes his hand between them and jerks him off again. satoru moans and gasps into his mouth, each jolt mirroring the pulses against his prostate.  

they separate for gojo to bury his face in yuuji's shoulders, arms hugging his neck. he humps into yuuji's hand until he comes against him again. 

he pants and huffs atop the boy, catching his breath. yuuji's gentle arms hold him, fingers rubbing slow circles at his back.  

satoru's breathing calms against yuuji’s neck. 

"yuuji, u're such a good boy."  

yuuji's heart and dick swell.
