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

Ch 4

*weeks later*

Over the next few weeks Sungyoon and I are both subjected to multiple different experiments. When we aren't being experimented on with multiple injections and blood work Sungyoon and I stay stuck in the white room where we talk about our lives and everything. Slowly waking up I blush when I see I'm snuggled right up against Sungyoon I quickly moving his arms away from my waist and scoot aside I sighing and run a hand through my dark red hair. Soon though the hidden door to the room slams open Sungyoon jolting awake and then suddenly we're both being grabbed with bags put over our heads I squirming in panic. After a while of being carried I feel myself be set down on a cold table and the bags ripped off of my head. The head scientist and doctor both approach me. "Today we're going to try a new serum to see how it reacts." I frown and try to get up and run but I'm immediately forcefully dragged back onto the table where I'm held down, restrained and injected with the glowing blue serum. I then continue trying to fight them off only to immediately be knocked out a little bit later.

*later on*

Slowly starting to wake up I groan feeling hot and achy all over I slowly trying to sit up only to immediately fall straight back onto the bed with an annoyed groan. I then suddenly feel a weird sharp pain run through my body I letting out a little cry. I curl up in a ball the weird pain getting worse and more intense. After a while of panting and crying through the pain I suddenly hear the door open I looking up to see Sungyoon being carried inside he being set on the bed beside me. I swallow a little my nose wrinkling as a really nice scent comes from Sungyoon I getting this hot needy feeling in me. After a moment Sungyoon starts to stir I seeing his nose wrinkle and a groan leaves him as he slowly opens his eyes. His gaze immediately goes to me and our eyes lock when I suddenly feel a sharp cramp run through me a little cry leaving my lips as I hug my stomach and feel something wet leak through my pants. Sungyoon immediately sits up looking worried his nose wrinkling. "Are you okay?" I whimper a little pitifully feeling that achy neediness run through me. "I don't know what they did but I'm hot and it hurts and feels like I need something." Another gush of wetness comes from me my mind getting fuzzy from the intoxicating scent of Sungyoon I letting out a little whine of pain and need. Sungyoon covers his nose he letting out a little groan. "Why do you smell really good?" I squirm and whine something completely taking over me as another giant puddle soaks through my pants. "P.... Please...." Something seems to snap in Sungyoon as well because he growls and gently moves so I'm pinned against the bed he crashing his lips onto mine. I moan immediately kissing back desperately my skin burning up and I feel a deep empty achy feeling inside me. We slowly pull away from the kiss I panting and whine with need. "Please!" Sungyoon groans and moves ripping my shirt off of me and he buries his face in my neck nipping and kissing leaving marks. "Mine." I shudder and whine instinctively saying in a submissive tone. "Y.... Yours." He growls and moves tugging his shirt off then rips off my pants and underwear I shivering at the cold air only to moan when I feel him enter a finger in me my entrance coated in a slick wet substance. He slowly enters a second finger in me and I moan bucking my hips down against his hand begging mindlessly. "Please!!" He groans and pulls his fingers out then undresses the rest of the way before he gently enters me we both letting out loud moans of pleasure I feeling a completeness fill my soul. "M.... Move...." He groans and slowly pulls out before thrusting back in I moaning loudly in pleasure. He starts a slow gentle pace burying his face in my neck and nuzzles against it with a moan. "God you smell so good." I whine exposing more of my neck to him only to cry out when he hits that special spot in me. "Sungyoon!" He groans and hits that spot with each thrust I whining and crying out in pleasure clawing at his back and shoulders. "G.... God Sungyoon c... close!" He growls and speeds his thrusts up a little murmuring huskily in my ear. "Finish for me. Cum all over my cock." I scream out in pleasure as I finish my body arching off the bed and I dig my nails into his shoulders shuddering when he lets out a loud moan and topples over the edge as well I feeling him inside me. Breathing heavily my minds still in a complete daze I feeling exhausted as Sungyoon slowly pulls out and moves so we're cuddling he burying his face against my neck saying in a husky voice. "Sleep." I grumble a little but slowly doze off from exhaustion.
