"Well, the handcuffs are pretty sexy, but they're not really my kind of fantasy, you know?” Kan declares satirically.
Thiu swallows hard, choking down his eagerness, already feeling the hot, high coloured blush creeping up his neck and flushing his cheeks a revealing rosy.
He's certain Kan is watching him intently, his head tilting curiously in the way it does when he's figuring something out, when he's piecing together a puzzle, the small smile swelling at his lips when he sees so easily inside of Thiu, even when Thiu doesn't mean him to.
Thiu bends forward to avoid the confrontation regarding his predilection, twisting Kan's wrist gently in his hand, his thumb pressing to Kan's palm.
The metal chain jingles quietly between the handcuffs as he works the key into the miniature lock, finally looking up when he senses Kan's astute eyes still on him.
Kan's full lips part slightly, his shrewd gaze holding Thiu’s, “leave them on,” he instructs plainly, his voice a quiet command laced with syrupy seduction.
“I..” Thiu starts, the words instantly dying on his tongue when Kan's eyes flit down to his lips as he licks at his own, his tantalisingly pink tongue moistening his lower lip, making it somehow even more inviting.
His stomach jumps and flutters, adrenaline sending blood rushing from his gut, and he gulps again against his arid dry throat, watching as a small smirk tugs at the corners of the doctor's lips.
“Stop teasing me,” he demands, exasperated, moving again to remove the cuffs from Kan's wrists.
“I'm not,” Kan huffs on a breath of a laugh, his face morphing into something much more serious after. “Look, I know I lied, but I'm serious about this. About us,” he continues, angling his body and dipping his head slightly to meet Thiu's gaze once more.
Thiu searches Kan's eyes, seeking out devious duplicity and finding none, consumed only by the fiery desire in them and the way Kan's pupils are blown wide and dark, the way they're so unbelievably, painfully honest.
He relaxes slightly, acutely relieved at Kan's earnest sincerity, allowing Kan to make his own exploration of Thiu's own eyes.
Then Kan's lithe fingers are slowly curling into the hem of Thiu's t-shirt, confidently tugging him closer, their lips barely a breath apart.
“So, you can leave them on. If that's what you want,” Kan adds enticingly, a gentle playfulness in the tone of his voice, a smile just breaking at the corners of his plush mouth, as heavenly and warm as a welcome sunrise.
Thiu can't hold himself back any longer, a broken dam of water rushing forward into Kan's space, obliterating the hairsbreadth of a gap that separated them, ravenously swallowing it down and kissing his lips.
Kan hums his delight into Thiu’s mouth, parting his lips to welcome Thiu's tongue to lave languorously against his own.
His knuckles brush the bare flesh of Thiu's stomach, and he sucks in a harsh breath, the touch cold and yet so desperately needed that his body wars between backing away and melting into it.
“Doctor,” Thiu breathes, gripping Kan's forearms for stability, attempting to keep a handle on the situation, attempting to disengage, attempting to remain professional in the face of everything that's happened since they first met.
Kan smiles against another huff of a laugh, “another fantasy of yours?” he asks mischievously before pressing his tongue suggestively to the inside of his own cheek.
Thiu scoffs, rolling his eyes, though the action is filled with overwhelming affection.
“Kan,” he corrects himself exaggeratedly.
“You really are cute,” Kan tells him suddenly, his smile widening when the crimson stain deepens across Thiu's face, his body betraying him once more, “so cute,” Kan repeats for good measure.
To shut him up, Thiu kisses him again, his hands travelling up the length of his arms, up the short sleeves of Kan's t-shirt, revelling in the goosebumps that erupt along the creamy, silken skin of his biceps, and squeezing at the firm muscle beneath.
When he pulls back, breathless and wanton, Kan lifts his arms above Thiu's head before lowering them to encircle his neck, the skin-warmed metal of the handcuffs pressing to Thiu's nape.
They kiss again then, until Thiu wraps his fingers around Kan's slim waist and pulls him to stand, turning him and walking him backwards to press him against the wall.
He takes hold of Kan's elbows, pushing up his arms, slowly unlooping them from around his neck, Kan's hands secured together above his head with Thiu's thumb curved under the chain of the restraints, keeping Kan's hands raised.
His other hand snakes between their bodies, over the soft material concealing Kan's torso, his fingers slipping beneath the waistband of Kan's trousers, stroking at scorching skin.
He watches as Kan's mouth drops open, his fingers closing into loose fists against his palms, head dropping back against the wall, his hair tickling at Thiu's skin, eyes, half hidden by lowered lashes, never leaving Thiu’s.
Biting at his lip, Thiu continues sliding his hand beneath the fabric, pressing his palm over Kan's arousal, their overheated skin separated only by the thin cotton of Kan's boxer briefs.
The shaking inhale that the touch elicits has Thiu's own erection twitching behind his zipper, his heart pounding in his ears as he finally reaches his hand inside of Kan's underwear, wrapping his fingers around the rigid heat of him.
He grips him tightly, twisting his fist to tug down his foreskin, thumbing at the florid, wet head of his cock.
“Thiu,” Kan gasps out, the handcuffs rattling against Thiu's hold when he tries to move.
Thiu lunges forward to mouth at the long line of Kan's neck, sucking kisses along the thick tendon there, groaning against his skin when Kan frantically fucks up into his fist.
Working him smooth and fast, he relishes the thick firmness of him, and the slick sound of pre-come has him breathing heavily against Kan's throat, haphazardly rutting against Kan's thigh to take the edge off of his own fervent need.
He kisses below Kan's ear and across his jawbone, his stubble scratching deliciously against Thiu's own, before taking his mouth unapologetically, his tongue delving inside.
Then he shifts the hand that's holding him in place above their heads, sliding their sweaty palms together and lacing their fingers, the fit even more perfect than Thiu had imagined.
Kan gasps at the vicious twist of Thiu's wrist, his breath hot and humid against Thiu's mouth, the noises he makes a litany of breathy moans and sensual whimpers, a symphonious melody composed only for Thiu.
Kan comes on a drawn out moan, his spend coating Thiu's palm, hot and sticky, as Thiu works him through his orgasm.
Both breathless, they kiss again, less desperate now despite Thiu's need to come, his arousal obvious in the growing dampness against Kan's thigh.
“If you take off the handcuffs, I'll give you a hand,” Kan tells him lewdly, eyes heavy lidded and coquettish.
Thiu huffs an incredulous laugh but reaches inside the pocket of his jeans anyway, fishing out the tiny steel key from inside and sliding it into the waiting lock at Kan's wrist.
