My future omega wifu (Alpha!Osomatsu x Omega!Reader)

🍋Finally!

It's Christmas. White snow covers the town this year luckily right into Christmas eve. Your parents wanted to have you, but they asked you when Osomatsu was cuddling you. So you couldn't resist his glares and said you'll come over around new year's eve.

Osomatsu wasn't fine with that even, but he could bear a few days without you. Even thought he would be pretty lonely. But you have this year a very special present to Osomatsu that he might like. Or more like, he would love it. You hope.

You two sit together in the kitchen and eat a special cake that only comes out at Christmas. For you pure heaven while Osomatsu enjoys to see you eating it. He's teasing you every year with gaining weight if you eat the cake all by yourself. But he only can tease you like that if you eat the cake. Or else he would need to sleep on the couch for a few weeks and isn't allowed to get any kiss from you or giving you some.

Osomatsu did this the first and last time. You too because he wasn't giving you any space to breathe after the weeks were over. Anyways, we miss the main theme here.

While Osomatsu eats a slice from the cake with an bored expression you feel rather anxiety. Osomatsu notice of course that you didn't eat one single bit from the cake you love even more than your fiancé. "(Y/n)?" "Y-Yes?!" You jumped slightly when Osomatsu suddenly speak up.

"You okay? Your face is really red. Do you have a fever?" Osomatsu ask concern. You shake your head quickly, but keep your eyes down at your cake. Osomatsu hums and eyes you up and down. 'Why is she acting so weird today? The last time I saw her like this was when we moved in together. Hmmm ...' You feel even more nervous from all the staring. You press your legs together while your body trembles slightly.

" ... Say, when can I have my Christmas gift, (y/n)?" You flinch and hold your breath in. Osomatsu smiles slightly, because he figured out what he gets from you. But where is the fun if he wouldn't let you say it? "W-Well um..." You glance up to Osomatsu, but when you see him staring at you with half closed eyes and already taking your clothes off like this your face turns completely red.

You look down on your legs again while pressing them harder together. Osomatsu stands up and walks over to you. "You need to tell me~. I really wanna know what my future wife is giving me before our wedding next year~." When you feel Osomatsu's hot breath against your ear a shiver runs down your spine. "Y-Your p-present um ... i-it's uh ... w-wait here a sec!" You suddenly stand up and leave panicked the kitchen. Osomatsu smiles a little and sit down on the chair. Waiting for you to come back.

After a few moments you came back with a small card in your hands. "Mpfh?!" But instead of handing it over to Osomatsu you throw it into his face and rush quickly out of the kitchen again. Osomatsu pouts and picks the card up. He turn it around with an bored expression before the card crumbles between his fingers. On the card stands: "Eat me"

Osomatsu's eyes turning red before he chuckles in a low voice. 'So you want it that way, eh? Fine with me~.' Osomatsu stands up and throws the card away. "(YYY/nnn)~! You know hiding is not possible for you~!" Osomatsu coos through the hallway. He scans the area before walking over to the bathroom. Your scent may be in the whole apartment, but Osomatsu always knows where you are when you sweat just a bit. And right now, it smells like you didn't took your suppressants today.

Osomatsu opens the bathroom door. Everything looks normal, but Osomatsu notice something. The cover from the bathtub is not completely on the edges. Osomatsu gabs the end from the cover and with one move it lays on the ground. "Ah..." But a t-shirt from you lays inside the empty bathtub. Osomatsu chuckles and turns around. 'She's really good~.'

Osomatsu steps inside the bedroom. Shutting the door a bit louder. "You're pretty smart, (y/n). But I know you since you were a kid aaaand..." Osomatsu put one hand under the bed and grabs something. "?!" Within a second he pulls it out.

Your face is red like a lobster while you look a bit helpless at Osomatsu up. He smirks before stroking your thighs, causing you to whimper slightly. "...I know how much you love it to hide under the bed~." Osomatsu licks his lips before lifting you up from the floor. "Uff!" Only to throw you onto the bed and to hover over you. Lust filled his eyes when he sees you finally under him with a shy and submissive face.

"O-Oso-mpf?!" Osomatsu smashed his lisp down onto yours. Kissing you hungry like he always wanted to. Osomatsu licks over your lips, but you keep them shut. You gasp when Osomatsu grinds against your still covered core. Osomatsu slips his tongue in your mouth. You moan when he press his tongue against yours.

Osomatsu starts to dry hump against you. He loves hearing you moan like this and can't get enough of it. But the best part is still coming. Osomatsu pulls away, what cause you to moan out loud. "You said I can eat you, right (y/n)~?" You flinch when a hand goes under your skirt and a finger gets pressed against your already wet underwear. "Looks like someone's excited~." "Aaah~!" You moan when Osomatsu pushed the underwear aside, only to puss his index finger inside your pussy.

"Mmm~ your so wet (y/n)~. And just from dry humping~?" Osomatsu hums in your ear. Sending you shivers down your spine. You moan when Osomatsu starts to trust his finger in and out. He put his face in the crock of your neck and inhale your sweet scent. "Huaaaah~! Your smell is sooo sweeeet~!" You moan louder when Osomatsu starts to lick your neck.

Osomatsu adds another finger and spread them, in order to stretch you out. Your heat starts to kick in. You clench your teeth hard together before moaning again and covering Osomatsu's hand in your cum. Osomatsu pulls his hand away and wipes the cum at the blanket away. Starting to pull his sweatpants down along with his underwear. "O-Osooo~" You whine.

Osomatsu smirks slightly and knock his forehead softly against yours. Pulling your skirt and underwear slowly off. "Yes?" You pant softly while looking with half lidded eyes at Osomatsu. "Pleeease~" "Please, what?" Osomatsu purrs and starts to lick your neck again. You moan and put your arms around his neck. "I ... I want ... you inside meee~!" You cry desperately while a few tears collecting in your eyes. Being in heat and don't get what you need hurts in your abdomen.

Osomatsu chuckles in a low voice before lifting your legs up. "As you wish~." "Oooh~" Osomatsu plunges deep into you, causing you to let out a loud moan. Beside pain you only feel pleasure. Osomatsu starts to trust into you and gets even faster with every time you call out his name. Until it's the only word you know. "Ah~! Oso~! T-Too deeeeep~" Hot tears running down your face and you reach your hands out to Osomatsu. Wanting to hug him close and getting a kiss.

Osomatsu understands what you wants and smash his lips down onto yours. Causing you to moan inside his mouth while he press his tongue against yours. When Osomatsu hits suddenly a special spot you moan even louder. Osomatsu pulls away and growls slightly. Trusting faster and harder into you. Hitting your sweetspot every time.

"O-Oso~ ah~ I-I cum~" Letting out a loud moan who is audible in the whole apartment you came onto Osomatsu's dick. "?!" When he pulls out, Osomatsu turns you suddenly around on all fours. You moan loudly when Osomatsu trust back into you. You start to see stars and some babbled words leaving your lips.

Osomatsu groans and bite down in your neck hard. You let out a whiny moan before cumming again. Osomatsu stills inside you with a growl. You flinch when Osomatsu ties you together with him. "W-Wha-" "I-It's ah~ o-okay, (y/n). I we-oh~ a c-condom." Osomatsu moans while his cum collects in the condom.

Since alphas cumming longer and more than others they have special condoms if they don't want their mate to get pregnant. But they are pretty expensive, because it's a special condom.

After a few minutes Osomatsu pulls out. To his luck the condom can handle so much cum. You whine when he does so, but your heat cools down. "Huaaah~! I feel sooo much better~!" Osomatsu throws the condom in the trash before pulling you close to him. Hugging you with a love sick look in his face. "Thank you so much for this present (y/n)~!" Osomatsu wants to kiss you, but he can see now that you fall asleep. Looks like having sex for the first time is too exhausting for you.

Osomatsu smiles softly before pulling the blanket over you two. Giving you a kiss on the forehead before turning the lights off. "I don't need to hold back anymore~. But for now, I'll let you rest (y/n). You're mine forever anyways."
