momo, as much of a merciless domme she wanted to be, loved fucking you. withholding you pleasure was a challenge to do so without doing the same for herself. especially when her favorite sensation was you coming on her cock.
frankly, she hadn’t expected for this to affect her as much as it had. she wasn’t going to go back on her word about sharing you, but she decided that some ground rules had to be established in this dorm first.
the alpha pulled her cock out, her hands fisting the head of her dick in a couple quick passes, and precum shone at its tip. you swallowed nervously now. the look in her eyes was particularly indecipherable.
“little whore, begging for everyone’s seed, hm?” she stood at the side of the bed where you lay, and your lips parted eagerly as she pressed it into your mouth. she pushed further until tears sprung to your eyes and you suppressed a gag. momo threaded her fingers into your hair and pulled lightly until you squeaked in protest.
“you’ll get all the cock and cum you need this week,” she growled. you nodded quickly. “but i’ll make sure that they all know you’re mine first.”
she pulled her cock out of your mouth in a sudden rush that had you gasping for air. it hung in front of you, a light string of your spit hanging from its tip connecting to your own lips.
god, you needed her.
but instead of fucking you senseless, momo only pulled herself back into her pants where it still strained quite conspicuously. she turned to peer absently into the mirror on the wall, fixing her bangs before casting a disdainful look your way.
“the group are coming home soon. clean yourself up, i think we’re having movie and takeout night.”
sana found you miserably dressing yourself and brushing your teeth.
“momo being mean?” she patted your back comfortingly. you only sighed plaintively, pitiful enough to make your friend laugh. “i guess you kinda deserved it, huh.”
you spat your mouthful of toothpaste indignantly, raising your head to glare at sana in the mirror.
“she said she wanted me to get fucked by you all.”
“yeah, but no surprise that momo wants final dibs on you.”
“well,” you stopped to gargle and spit. “she isn’t even fucking me, so i don’t know what she wants anymore.”
—
what she wanted, you discovered quickly, was to embarrass you.
you forgot what film was being played very quickly. the takeout was tteokbokki and gimmari, of which you could only stand the latter because any sort of heat would’ve fully ended you.
you were dressed in a tank top and shorts. you’d debated trying to maintain your modesty in pants that would somewhat retain your scent to yourself, but the discomfort on your skin won out.
when you shuffled out of your room to the rest of the group, conversation quieted slightly.
sana waved brightly, gesturing to you to sit between her and momo. jihyo couldn’t hide her own grin as you passed, and a jolt of arousal passed as you recalled the sensation of her turn inside you.
but now the rest of the group was attempting to carry on as usual for your dignity’s sake.
jeongyeon was desperately trying to avoid looking at you, chatting with a nayeon who was very much not trying to look away. mina appeared collected, though she bit her lip in that slight tell of hers.
the omegas were at varying levels of attentiveness. tzuyu and dahyunie seemed taken aback, while chaeyoung only giggled.
the film started. only a few minutes in, momo tapped you to sit in her lap. you complied, and found yourself sitting on the cock she had pulled out of her pants. she pulled your flimsy sleep shorts aside and slipped inside of you, rock hard with anticipation.
you stifled a sigh.
the film was apparently good. sana and the others were clearly absorbed, and you tried to feign attention as well.
until you looked to momo’s side and saw nayeon slowly stroking herself in her shorts, a spot of moisture staining their front. momo chuckled.
“you’re going to warm my cock until you can’t take it any more,” she murmured, below the volume of the television but just loud enough for those around you to hear. nayeon quickened her pace, and you blushed in embarrassment. could the others smell what was happening too?
“are you going to fuck me in front of them too?”
“no…i don’t think so. but that’s not necessary. you’re a loud fuck anyway.”
she shifted below you as if to prove your point, the slight displacement causing you to choke back a whimper.
now sana glanced over in surprise, then mild amusement, turning back to the film with little reaction.
nayeon’s pretty dick twitched. the eldest member didn’t seem too bothered about staying up much longer. you realised in a shock of fresh shame that to her you were just a quick wank. nayeon met your eyes in a smirk that ended up an open-mouthed sigh of pleasure. she came, a reasonable load of cum showering over her own skimpy crop top.
you burned with longing for her white seed. what a waste.
“what are you thinking of, you needy omega?” momos voice cut into your consciousness. “nayeon unnie only came because she thought watching you was interesting. that cum wasn’t meant to be for you.”
you hung your head, nodding.
the next half hour was spent like this; her cock warm and present inside you, you struggling to sit still and stay quiet. you knew that she was building up her orgasm as much as you were—her favourite thing to do for your heats.
you realized that your members were acutely aware of what was happening. mina cupped her bulge and sighed, but went no further. jihyo glanced back a couple times, patting your knee comfortingly. jeongyeon leaned to whisper into nayeon’s ear a few times, and judging by their quiet giggles it didn’t take much to imagine what the topic of conversation was.
sana played with your hair, fidgeted lightly on your thigh, leaned against you, fully in league with momo to gradually work you up. momo herself was an unsympathetic presence; her firm hands still on your hips and thighs, her cock still and hard inside your throbbing pussy. she leaned forward to whisper in your ear.
“who are you going to ask for first after i’m done with you, y/n?”
“i don’t know…” you sighed softly, being completely honest. none of the past day had been planned.
“should i decide for you? only the best for our best little breeding omega.”
you let out the softest whine. luckily the film was just as loud.
“momoring, please,” you gave in at the forty-five minute mark. “i can’t do this.”
“lost patience already?” she whispered back.
“momo i’m in heat, this isn’t fair…” you paused, weighing your tactics. “take me and breed me.”
you knew her own composure was wavering.
“knot me full of your cum and make me yours,” you continued. her cock twitched inside you as she flexed her muscles under you, suddenly antsy herself. her hands ran over your thighs, closer to their junction now. “momo, i need you.”
apparently that was enough encouragement, because she was already lifting you off of her and tucking herself back in her pants. as if the room wasn’t aware of what the two of you were off to do.
“we’ll finish the movie later,” momo said shortly to the amused group, following you into your bedroom.
you’d only just turned around when the door shut and momo had you pressed up on the wall, her cock hard against you through her pants. you made the most stereotypical omega whimper, palming her bulge until she let out her own sigh.
she kicked her trousers off, pulling the crotch of your shorts and underwear again to plunge into you, fucking you into the wall behind you. you keened obscenely.
“momo, fuck,” you chanted breathlessly, the sensation of her cock sending fireworks though your body as it pressed deeper inside you. nearly an hour of cockwarming had made the two of you desperate. you loved your momo like this–lost in your scent dripping of heat and need, her basest instincts seeking your cunt and making you hers, hearing you cry out in conjunction with her own pleasure.
just as you felt like you’d develop bruises from the roughness of her fucking against the wall, she took you toward the bed instead. her cock leaving you made you a little crazier, quickly getting on your knees and presenting for her. “please, please,” you whispered until she was back inside, and everything felt right again.
your alpha found your hair and pulled lightly but firmly, her other hand pulling you against her with every thrust. for a moment you were just putty in her hands, surrendered to her. the thought of being used for the alpha’s pleasure was what gave you your first climax.
the pulsing around her cock was unbearable, you knew. momo panted harder, in the way you knew she got when she was so close, but was just holding on a little longer for you, to get every final drop for you. she knew how to sate you, to give you what you didn’t even know you needed.
her knot was swelling, large and firm at the base of her alphahood. if it hadn’t been for your heat wetness and receptiveness, fitting it inside would’ve been overwhelming. but now it felt like momo had been created to complete you. it finally slipped all the way inside, but she thrust a few times with it, reaching into parts of you you hadn’t known existed. tears sprang to your eyes at the sensation, doubly so when you felt her bite down into your shoulder (a half-mindful compromise from a real mark) and finally empty into you with a guttural moan.
there was nothing quite like the sensation of being filled while in heat. evolution had lead to this moment–the feral bliss of being claimed and bound to an alpha, giving you what every fiber of you being had demanded with white-hot, mindless intensity. your muscles spasmed helplessly, as did her hips erratically against yours. you knew your high pitched babbling was definitely audible, but you couldn’t care. the thought of the other members listening to you being bred only made you even more gratified.
“good girl,” momo murmured, leaning down to speak into your ear. you sighed at the praise, your pussy fluttering. “such a good breeding omega.”
she laid the two of you down, spooning tightly. for once your heat seemed satisfied, the seed of two alphas sating the desperation that you’d endured that morning. you felt full, curled against the warmth of your alpha.
momo pressed a gentle kiss to your sore shoulder. “i’m sorry, i got a bit carried away,” she murmured, real regret tinging her voice. you shook your head.
“no, it’s okay. it’s hot.”
“oh,” momo laughed lightly. “okay.”
you sighed, listening to the movie play muffled in the next room. “you’re so good to me, momoring.”
“it’s the least i can do, y/n-ie,” she replied, giggling at your dopey silliness. you shook your head sleepily, backing further into her hug.
“no, i mean, in general.” you yawned, your thoughts dissolving into drowsy nonsense. “you’re really…nice to me…”
“of course, baby,” she nuzzled your neck. “go to sleep now.”
but you were already halfway to a deep, satisfied slumber.
