Dark side (a Y/Choi Sungyoon x male reader story)

Ch 5

Slowly waking up I feel a little confused and still have a hot achy feeling in my body. Blinking away the sleepiness I pause when I notice I'm naked and being held against Sungyoon who also isn't wearing any clothes. Eyes widening yesterday comes back to me like a ton of bricks I remembering the experiments and the excruciating pain and horniness. I also remember something completely snapping in me it like my instincts completely took over my body and mind. Swallowing I try to maneuver myself out of Sungyoon's arms still feeling that hot achy feeling only for his grip to gently tighten he pulling me back to him with a husky "don't go." I blush a little as his eyes open he looking down at me with a strange look he murmuring huskily. "You smell so good." I bite my lip my stomach flipping with arousal and that weird wetness starts to form again. "S.... Sungyoon...." He cuts me off with a firm kiss I freezing up at first before my instincts take over again and I kiss back eagerly. Suddenly I'm being gently laid fully back against the mattress with Sungyoon hovering over me he running his hands all over me and I let out a little moan arching into his touch. We slowly pull away from the kiss and he gently enters a finger in me I letting out a loud whine bucking my hips downward. "Please!" He pulls his finger out then positions himself at my entrance before he gently enters me we both letting out loud moans that full complete feeling hitting me again. "Oh god move.... Please." He groans and starts a slow but sharp pace little moans and whimpers of pleasure leaving me only to cry out when I feel him hit that spot in me. "Sungyoon!!" He moans and hits that spot with each thrust cries of pleasure leaving me as I claw at his back and shoulders in ecstasy. "God Sungyoon c... close!" He growls and speeds his thrusts up a little burying his face against my neck. "Finish for me. Let go." I whimper then scream out in pleasure as I finish he quickly joining me and I moan when I feel him inside me I feeling completely dazed. We stay together breathing heavily when my mind starts to slowly clear I immediately feeling embarrassed and anxious when I realize that whatever they gave us yesterday must've drugged us and messed with our instincts or something. Sungyoon slowly starts to move he pulling out making me wince slightly at how sensitive I am he giving me a concerned look. "Did I hurt you?" I blush but shake my head no reassuringly my voice a little hoarse from the screaming I did. "Just really sensitive." He slowly nods before saying softly. "I'm sorry for taking you without us being in our right minds." I give him a reassuring understanding look. "It's okay. They obviously drugged us with something that made our instincts go crazy. And I'm glad it was at least with you and not a complete stranger." He immediately looks angry and protective when I say that. "I won't ever let anyone else even try to touch you." I blush a bit at that before saying appreciatively. "Thank you Sungyoon." Our eyes lock and I get this weird feeling in my stomach and chest. Like a strange warmth. Staring at each other we unconsciously start to lean forward our lips becoming inches apart when there's suddenly a loud commotion coming from outside that sounds like an explosion it snapping us out of our daze. Quickly scrambling to my feet I grab my clothes tugging them on Sungyoon doing the same then we rush to where the hidden door usually is we yelling out for help. After a few minutes the door opens to reveal Sungyoon's leader he looking relieved when he sees us. "Come on hurry and we'll get out of here." We both nod and rush out of the bright room that I admit I'll kind of slightly miss. Quickly running through the large building we meet up with everyone at an exit the kid looking a little grumpy and annoyed about something but he ushers us to come on we leaving the building as fast as possible. Once we're all away from the building as far as possible I look at everyone with a raised eyebrow feeling grumpy. "Sure took you guys long enough to get us." The guys leader speaks up defensively. "Blame Cyrus he wouldn't let us make a move for the longest time. We finally tracked you down and had to fight him on coming and getting you." Sungyoon and I both turn to the kid with raised eyebrows and wary looks he saying defensively. "It's not what you're thinking! I just had to ensure you two stayed there for a while." I immediately give him a sharp look. "Why? Because we both went through hell with experimentation and abuse." He flinches looking upset and guilty. "I know and I'm sorry but it's for the good of the future." I scoff angrily. "How was leaving us there for the good of the future?! Huh?! Tell me! Because I don't think anyone should have went through what we did!" He flinches before blurting out in an upset tone. "Because it was to ensure I was born okay!!" I go quiet at that and give him a confused look like he's insane. "To ensure you were born? What exactly does that mean?" He goes quiet and I give him a sharp look. "So help me kid you better spit it out or I'll encase you in darkness because I am seriously not in the mood." Sungyoon speaks up beside me his tone slightly softer. "Just explain." Cyrus lets out a puff of air. "I had to make sure you two were captured and went through the experiments because without them experimenting on you guys I won't be born because you guys are my parents." I stare at him for a moment before saying in disbelief. "You're fucking crazy. I'm a guy I can't get pregnant." He winces and rubs the back of his neck. "The experimentation they did on you guys made it to where Micah your biology was altered to the point where your body now has the ability to carry kids." He then shifts a little awkwardly. "So um when they gave you that last injection it made you basically go into heat like a female animal and Sungyoon they injected you with some things to make your instincts take over while around Micah. It's why I was so reluctant to let the guys come get you because I didn't know if it was enough time to get the serum injected in you and for you both to be together." I stare at this kid in complete and utter disbelief before saying in denial. "Nope. Hell no. I am not going to get pregnant it's not possible." The kid frowns looking upset. "Dad please." I flinch at that name shaking my head. "I will not believe anything until I have scientific proof." Cyrus's mouth just barely lifts up before he turns to Sungyoon's leader. "Call Sungyeol hyung and have him do a check up please." The man raises an eyebrow but nods and I look confused. "Who's Sungyeol?" Sungyoon gives me a reassuring look motioning to the leader of the group. "He's Daeyeol hyungs brother and a doctor." I slowly nod feeling wary. "Alright then." We then head to the guys headquarters after Daeyeol makes a call and I'm lead to a medical room where a tall older man is standing he giving me a kind smile. "I heard about you two being experimented on and needing a check up. Who wants to go first." I gently shove Sungyoon towards him he giving me a slight look but lets the man give him a check up he looking curious when Sungyoon can see, hear and smell way better than a usual human. Once Sungyoon is cleared it's my turn I gulping but I head over and I can also see, hear and smell better than usual humans. The older man then has me lay back against the examination table I reluctantly doing so and he wheels out an ultrasound machine. "Lift your shirt up please." I swallow but do so and he squirts some gel on my stomach before pressing the wand thing down on my stomach he moving it around only to pause staring at the screen. "It seems your inner anatomy has changed completely. You have inner female anatomy and a uterus to carry a baby. I don't know if you'll be able to get pregnant though." I immediately pale my eyes going to the kid in disbelief but now that I study him I see why he looked so familiar because he has my eyes and a lot of Sungyoon's features mixed with mine. He gives me a little reassuring smile saying softly. "So do you believe me now?" I gulp and look over at Sungyoon. "So we're going to have a son...." He nods and I run a hand through my hair anxiously. "I don't know about this. I'm seen as a supervillain for gods sake and I can't raise a baby with someone I just barely know." I see Cyrus look scared as his hands start to fade. "Dad seriously! You can do this! Please!" I frown before saying in panic. "Okay! Okay! fine!" His body starts reappearing he looking relieved. "Thank you." I sigh and look at Sungyoon pitifully. "I guess we're stuck together now. At least to co-parent." He places a comforting hand on my shoulder. "I'm sure everything will be fine." I slowly nod then rub my eyes after wiping off my stomach with a towel feeling exhausted Sungyoon's expression softening. "Let's get you some rest." I go to get up when Sungyoon gently scoops me up into his arms he carrying me out of the medical room and to the room he got clothes out of when I first arrived. He gently lays me on the bed I immediately relaxing at the nice comforting scent and I almost immediately fall asleep.
