Sohee isn’t even that short, honestly. Sure, he may be on the thin side, not as stocky as Chanyoung or as built as Wonbin is, but for Korean standards, he's average height.
Obviously standing right next to Jung Sungchan makes him look ten times smaller than he is. It would upset him in any normal circumstance, but right now, it turns him on beyond belief. Sungchan’s broad hand finds its way to Sohee’s chin, his much longer fingers digging into the soft plushness of his lips. Sohee’s panting, flushed, and barely registers the fingers tracing his lips.
Sungchan bullies his long fingers into Sohee’s little mouth. Even his mouth is tiny, smaller than Sungchan’s. He can only fit a few inches of Sungchan’s length in his mouth before he gets teary-eyed and gags. Sungchan easily can swallow the entirety of Sohee’s dick, smaller in size by a few inches than Sungchan. It embarrasses him. Everything about their size differences make him embarrassed and horribly turned on.
Sungchan’s taller frame pins Sohee to the wall, practically pushing his cheek to the cold tile of the bathroom. Sohee arches when Sungchan plasters himself to Sohee’s back, forcing his chest to hit the tile. Sungchan tightens his grip on Sohee’s lithe waist, pinching the skin there.
“You’re so small, baby.” Sungchan has to practically lean down to whisper into Sohee’s ear. The younger boy just moans stupidly around Sungchan’s fingers in his mouth, pushing and arching his hips back to meet Sungchan’s thrusts. He suckles gently on the tips of Sungchan’s fingers, hazy with the fact that he’s not even knuckle deep into his mouth, just the tips of his fingers.
Sohee’s gut tightens when Sungchan hits the bundle of nerves inside of him, melting further into the bathroom tile as Sungchan supports his weight.
“H- hyung,” Sohee whines, one of his smaller hands wrapping around Sungchan’s wrist, the one supporting his waist. He can feel his dick twitch with the lack of attention, hanging uselessly in between his legs, he lets out a broken moan as Sungchan quickens the pace, hammering into his prostate. His thighs quiver with the pleasure wrecking his body, barely holding up his body. Sungchan is stupidly strong and tall and big, holding Sohee up like scaffolding on a building. Sungchan crowds him impossibly closer to the wall.
Sungchan removes his fingers from Sohee's mouth, holding Sohee by the front of his throat, pulling him backwards to lean against Sungchan’s chest. He nips at Sohee’s ear lobe.
“You’re twitching everywhere. I can feel you squeeze around me.” Sungchan emphasizes his point by placing a hand on Sohee’s lower abdomen, where Sungchan is shallowly thrusting in and out. Sohee whimpers, placing his hand on top of Sungchan’s. He wonders how thin the skin on his waist is. He wonders if Sungchan could reach so deep inside of him that his thick length could pierce through the skin, stake his claim on his body.
Sohee moans wantonly at the image. Sungchan bites at the side of Sohee’s throat, feeling the way he tightens around Sungchan at the fantasy.
“What’s going on in that pretty head of yours?” Sungchan tilts Sohee’s chin to face him. His eyes are lidded, cheeks flushed, lips bitten raw. Sungchan’s eyes rake over his ruined face, leaning in to press a passionate kiss to his pouty lips. Sohee melts into the kiss, fingers tangling onto Sungchan’s shirt on his shoulders.
A rough thrust to his already ruined hole as him yelping into the kiss, dick twitching and throbbing in between his legs again. Sohee whines, fidgeting and thrusting into the air and back onto Sungchan’s length, piercing him. He can feel every ridge of Sungchan’s cock, and it’s so so deep.
Sohee shakily brings down a small hand to wrap around the base of his dick, slowly stroking in time with Sungchan’s deep thrusts. Sungchan nips at Sohee’s lips meanly. The hand on Sohee’s lower abdomen wraps around Sohee’s practically engulfing his little hand and the entirety of his dick. Sohee moans at the pure imagery on its own.
Sungchan rests his chin on the crown of Sohee’s head, following his gaze.
“So tiny, so perfect.” He punctuates his sentence with a deep thrust, jostling Sohee, who grinds against Sungchan’s palm, his thumb catching onto the precome beading at the tip. Sohee whimpers, overwhelmed by the pleasure on both ends. He can feel how big Sungchan is inside of him every time he clenches down, every time he hits that bundle of nerves that make his dick twitch, his abdomen jump. Sungchan tightens his grip around Sohee’s hand on his dick, moving it up and down forcibly.
Sungchan sets a mean pace, rubbing the pad of his thumb against the tip, watching as Sohee cries out, tears staining his cheeks. Sungchan switches from rough thrusts, then to a slow grinding pace that sets off sparks behind Sohee’s eyelids.
“Hngngh-ff- hyu-hyung-ah-” Sohee moans brokenly, dumb. Sungchan’s hand still on the front of his throat tightens, and Sohee’s eyes shoot open. He braces himself against the tiled wall with one hand, and the other comes to paw helplessly at Sungchan’s grip on his throat, encasing the whole thing. He could choke him out so easily, leaving him strung out and dead.
Sohee moans, eyes rolling to the back of his head at the lack of oxygen as his moan dies on his tongue, clenching down on Sungchan’s tip as he slams back in. Sohee’s come spurts onto the tiled wall, all over Sungchan’s fingers. Sungchan could catch all of his come in one hand, a pathetic daintiness about his load. Sungchan grunts at the throbbing pleasure, Sohee’s hole clenching down on Sungchan’s length as he comes in waves.
He grunts from behind Sohee, grip tight on his throat as he strokes Sohee through his orgasm.
“Take it.” He buries himself with a groan as he lets his dick hit the deepest parts of Sohee, twitching with each spurt of come, pouring into Sohee’s ruined hole. Sohee slumps against Sungchan’s chest, arching as he’s filled.
“Hnggf…” Sohee moans at the sensation, twitching his hips. Sungchan’s strokes border on overstimulation as he tries to wiggle out of Sungchan’s grasp, forcing his cock deeper. He gasps brokenly, the sound tapered as Sungchan slowly lets go of the boy’s throat.
Sungchan hopes it leaves a mark on that pretty pale neck of his.
Sohee coughs, catching his breath as his thighs quiver. Sungchan presses a kiss to his cheek, holding him up by two broad hands on his hips, engulfing his waist. Sohee leans into the touch, letting Sungchan press open-mouthed kisses to Sohee’s nose, trailing down to those pouty lips, bitten raw.
“Hyung loves you.” Sungchan says gently.
