"want to prep me?"

mark asks when he crawls back to join jaebum in his bed, lube and a foil package in hand. jaebum's cheeks flame with embarrassment. mark chuckles lightheartedly at him.

it's not that he doesn't want to prep mark, ease him open with his fingers until his eyes are glazed with lust, mouth open but no sound, silently begging for his cock. it's just he doesn't know how. mark takes his embarrassed silence as a no.

"it's okay. I can-"

"no. I mean, yes. I want to..." jaebum stumbles with his words. he licks his lips in nervousness and mark can't help but to lean over and takes his mouth in a hungry kiss.

"but?" he breathes against jaebum's lips after releasing the bottom one between his teeth.

"I don't--don't know how." jaebum sighs shakily back

"don't worry. I'll teach you."

mark sinks down on him, eyes closed, jaw slack, body language belying nothing of the shyness people assume once meeting him.

jaebum runs the pads of his fingers over taut muscles of mark's stomach, in what he hopes is a reassuring manner.

mark is a steady hot tight burn around him, jaebum trembles from the effort of not starting to thrust up instantaneously once he's bottomed out in him. mark laughs softly at him, mouth coy before bending down to lick a bead of sweat trickling down jaebum's neck. he groans at mark's movement, hips jerking, and said male gasps and clenches around his cock in surprise.

"shit!" jaebum curses, grabbing mark's wrist, "did I hurt you?"

mark shakes his head no and asks, "are you ready?"

mark doesn't wait for jaebum to respond and lifts his hips up before quickly sinking down once more in one fluid motion.

jaebum's hips working a steady rhythm into mark, hands reaching over and parting mark's asscheeks, exposing his glistening hole as it swallows jaebum's cock whole.

he pushes mark chest down on the mattress with a palm on his back, urging the older male to pop out his hip at an angle.

mark can only wrap his arms around his pillow and stifle wanton moans as jaebum hits his swollen prostate with precision.

mark's cock is slapping against his stomach and on jaebum's thighs but he couldn't care any less as the way jaebum is circling his hips as he's fully sheathed in mark's tight heat is almost enough to make him come.

almost. he needs a little more.

mark's body reacts on its own as he finds himself pushing back, grinding his taut ass towards jaebum, seeking more friction as he meets him thrust for thrust.

jaebum grabs his bouncing cock and a strangled moan of blind pleasure tumbles out of mark's mouth when jaebum gives the head a firm pinch between his thumb and forefinger and slicks the neglected length with precum. mark throws back his head and another moan is out when jaebum presses a bit of nail into the slit.

it doesn't take long for mark to come, not when jaebum finds his circumcision scar and relentlessly rubs his calloused thumb over it until mark is screaming his throat hoarse. he's begging jaebum not to stop until he's shooting lines of white and trembling violently, jaebum's name tumbling from his lips as he does.
