student/teacher

i can’t get back to sleep so here’s more omega teacher shinji & alpha student shirou!!

the school had to be informed of shirou bonding shinji, but it was regarded as an incident that couldn’t have been helped considering the circumstances. they are both given wellness exams and counseled about their relationship in concern to the conditions of their union, which is likely to be a common thing in the grander scheme of things among people with secondary genders. they are given specialty suppressants that are much stronger than those given to a typical alpha or omega since they’re needed to control shirou’s pheromone release and shinji’s release in reaction to him, which has already begun to make him dizzy and lightheaded during classes. they do a decent job helping them function normally in their daily life, but considering shirou’s exceptional background they aren’t exactly foolproof. shirou is still far more susceptible to detecting pheromones of other alphas, especially since shinji has begun to start showing more physical indications of being an omega. it can’t be helped, but it still makes the both of them tense.

one day after school shinji is feeling weak and with vertigo enough to have to find another teacher to lead the kyudo club. shirou is immediately by his side, having felt his small but growing feeling of distress. shirou insists on helping shinji get home, which only furthers the gossip and rumors about them among the other students.

shirou walks shinji home, stopping to let him rest every so often. in the morning during homeroom he felt fine being able to gently soak up shirou’s fond and protective feelings. it’s become a comforting warmth. but after, once he’s settled into that state of complacency with a natural increase in his scent it then becomes much easier for him to soak up the eager and agitated pheromones of other alpha students and faculty. it’s gotten to the point where it’s so overwhelming that it’s become difficult to get through the entire day on his feet.

he’s red faced and panting as he sits beside shirou, trembling and starting to sweat. he wasn’t supposed to to start his heat for several weeks, but from constantly absorbing such strong alpha pheromones it’s triggered a weakness in him. as he can feel himself begin to slowly leak, he distantly but urgently insists they get up and get back home.

once he staggers through the door and hears shirou lock it, his knees immediately buckle. of course, shirou is there to eagerly catch him and support him, easily picking him up. shirou has gotten a lot stronger lately. he’s taller; more broadly shouldered with more pronounced biceps. with glazed over eyes and an urgent whine, shinji breathes hard, not even able to articulate that he needs to lie down. he used the very last of his will to be inside the safety of his home.

shirou wastes no time getting him onto the bed and starts to remove his sweater and shirt, resisting the surging impulse to simply rip the fabric off his body. as it is he accidentally tears buttons off of shinji’s button down shirt. heated skin exposed to cool air, shinji’s chest immediately begins heave with an increasing need and shirou can’t help but admire him. with his hair sweat soaked and sticking to his face and his hands anxiously gripping the fabric of his sheets, shinji whines in a way that he would never register as his own voice. it hits shirou at his very core and he can’t help but touch. with his strong hands he gives into his fascination and begins to touch him and enjoy how he trembles when he strokes and cups at shinji’s chest, admiring the developing shape and the soft puffiness of his nipples. as he thumbs over them shinji moans and arches his back, pressing himself further into shirou’s hands. he’s more than happy to oblige. his hands wander down shinji’s torso, thumbs pressed into soft skin now covering his hip bones before unhooking his belt and tugging his pants down. shirou can’t help but admire shinji’s whole body for a moment, noticing all of the subtle changes that he has caused. knowing that shinji is very much a work in progress produces such a burst of warmth within him that he doesn’t waste any more time — he removes his clothes and gingerly picks him up, he places him in his lap and immediately bites him as he begins to finger him at the same time. shinji starts to deliriously beg for him. it was all he needed to hear. it’s the easiest thing for shirou to situate him properly so shinji to can lower himself down into him at his own pace.

shinji’s pace, however, is quick — desperate and frantic. feeling himself full of shirou’s dick is enough to bring him to tears, his need to be satisfied having quickly pulled him into a fever-like state of urgency. with shirou’s hands lovingly gripping and kneading at soft hips he helps move shinji, delighted by the sounds he makes and the way that he pushes himself down into him with an eagerness he hasn’t experienced yet. it inspires both a fondness and carnal emotion within him. he bites into shinji’s perpetually healing mark, feeling him quake as he starts to sob. his voice is low and rumbling when he tells shinji how cute he is.

eventually shirou can’t take it, and he flips shinji around so he can push into him with all of the energy he’s been holding back. he hooks shinji’s legs over his shoulders and presses into him deeper than he ever has before. it makes him hiss in such a possessive way as shinji continues to sob without restraint, both in delight and dismay as he feels the pressure and tightness swiftly increasing between them. shinji squirms as they’re locked together on shirou’s knot and while he feels mentally incapacitated, shirou tells him how good he is and taking all of him.

when shirou finally releases, rocking into him with as he throws his head back. shinji’s voice dies in his throat at the electric sensation of being filled. it happens again and again until there’s so much pressure that he passes out, still very much attached. shirou knows and feels that shinji is safe and overloaded on pleasure without a second thought and finishes so lovingly, lying down to collecting his body back into his chest and stroke his hair back to kiss his forehead. as they eventually unlock from one another shirou can’t help but marvel how stretched and warm shinji feels as he pulls out. he thinks that shinji has to be really strong to endure this with such happiness and that omegas really ought to get more credit.

when shinji comes to the first thing he feels is a very distinct sort breed of pressure. with everything that’s collected inside him, the fullness that he feels makes an overwhelmed sensation wash over him as he instantly remembers how it felt to have shirou’s knot inside him. he feels cum slowly leak out of him and recognizes the dry stickiness that coats the inside of his thighs. a moan catches in his throat as he shifts his body and still feels how impossibly full he is. it’s so satisfying he almost doesn’t want it to go away. still, he has more than plenty of time to enjoy it. shirou has him pulled close, fingers grazing over shinji’s skin and breathing into the crook of his neck. his teeth tease over the mark as he brushes his hand down shinji’s chest and presses his fingers curiously into shinji’s lower abdomen, pressing them into the soft skin. the slight rise to his stomach makes him spark with all sorts of possessive emotions as shinji trembles. he doesn’t want this to go away either. one way or another he feels a carnal sort of desire to see and feel shinji full of him at all times. shirou licks at shinji’s mark until he can feel his body relax against him, having fallen into a deep sleep.
