“One, two, three. One, two, three. Just like that, okay?”
Changbin’s breath came out in shudders, so noisy that you wondered if he could even hear you over them. Judging by his scrunched up nose and furrowed eyebrows coming together to form an adorable look of concentration, you doubted it. He was focused on one thing and one thing only.
“Binnie,” you sang. “Are you listening to me?”
Just to make sure you had his full attention, you brought the steady roll of your hips to a halt, keeping your strap buried inside him, but denying him the friction that had wiped all coherent thoughts from his brain. His body rocked for a few seconds more even after you’d stopped, operating purely off muscle memory. Then, it turned into squirming, hips twisting helplessly in the sheets to try and regain the buildup of pleasure he’d suddenly lost. You watched him wiggle around, half-amused, half-endeared as he finally blinked his hazy eyes open to process what was going on.
“Mm?” he mumbled; drowsy, like he’d been stirred from a dream. “S-sorry? I didn’t…”
His gaze fully refocused to find you smiling down at him. On your end, you could’ve sworn his pupils dilated just a little bit more, painting his irises black and glazing them over. They looked so innocent, you’d never guess what he was really pleading for.
“I said,” you began playfully, running your palms up his twitching thighs just to tease him. They felt especially thick under your touch with all the tension they were holding, you couldn’t resist digging your nails into his flesh, hard enough to leave crescent-shaped indents behind. The tight clench of his muscles was almost as satisfying as the sweet little gasp he let out. “Are you listening to me?”
Changbin swallowed down the saliva that had begun pooling in his mouth, sucking in a deep breath to find his voice again. “O-oh, yeah.” He shifted on the mattress to inch himself closer to you, as if your strap didn’t already have him filled to the near brim. “Yeah, listening. Sorry.”
“What number are we on, baby?”
He paused, doll-like lips curving deep into a pout. It was almost cute enough for you to let him off easy—almost.
“I…I don’t—” he chuckled nervously, eyes flickering to the side. “F-four?” You shook your head. “Five?”
You could tell he was growing restless, even when he was doing his best to behave himself. His dick twitched against his stomach, crying out for you to just forget about the count and start thrusting into him again. All the blood in his system must’ve pooled hot in his abdomen by now, you couldn’t even blame him for not being able to think straight.
“S-sorry, I really can’t remember,” he stuttered, embarrassed. “Again?”
It was the second or third time Changbin had lost track by now, and he once again found himself cursing the second he’d ever let his pride rope him into this tortuous little game you’d proposed. He’d never been one to back down from a challenge, even if it was a challenge that you both knew full well he’d fail miserably at. That, combined with his insatiable need to impress you clouding his better judgment, had him playing right into your hands.
“I can multitask!” he’d protested. “Do you know how much work it takes to be this cute and sexy at the same time?”
“So much work,” you’d agreed solemnly, trying not to crack a smile over the defensive squeak in his voice. “Then this should be no problem for you, right?”
From the moment you’d first bottomed out inside him, Changbin had gotten the sense that he’d already lost.
“I’m trying to help you, baby,” you pouted down at him. His eyes fluttered shut as you dragged your index finger along his plump, wet lips, mesmerized with the cute popping sound they made every time you prodded at them. “If you’re too dumb to count by yourself, just repeat after me.”
“N-no, Binnie’s smart,” he insisted, muffled by your finger. His legs squeezed around your waist like they had a mind of their own, trying to rub against each other and generate some friction. “Not dumb. I can do it, lemme do it.”
“Yeah? Let’s try and make it past three this time.” You gave his cheek an affectionate pat. A shiver ran through his body as your hands glided down to his hips, gripping his soft flesh to stabilize yourself before inching out of him bit by bit.
Immediately, Changbin’s attempt at counting was cut off by his own whine, stretching out for every second the silicone dragged along his walls. Then, you heard it, shaky and breathless as you pushed back inside him.
“O-one.”
His stomach rose sharply under your palms as you pulled out a second time. Before you’d even snapped your hips forward again, he gasped out a “two”, all too eagerly. You giggled, waiting a few extra seconds just to test his patience
“Two,” he repeated with a tinge of desperation. He looked lost, like he was genuinely wondering if he’d already managed to mess up the order somehow.
You felt a tinge of pity; he really was trying his hardest for you. So, you followed through, deciding to take it slow this time so he actually stood a chance in counting your thrusts. His foggy brain was grateful for it, but his body, not so much.
“Th-three—ah. Three. Faster, please?” he barely got the words out in time before he felt that delicious stretch again, coaxing an especially high moan. “F-four.”
You could practically taste the hunger rolling off his skin in warm waves. Every needy noise that grew louder his throat, every jerk of his hips begged you for more, even if he knew he wouldn’t be able to keep up with it. His teeth sank into his bottom lip when you pushed back inside of him without missing a beat—faster, just like he’d asked for, and as deep as your position would allow. You dragged your hands up and down his stomach in unison with the slide of your strap; such a simple touch, but enough to disrupt his concentration all over again.
“Fi—” he began. His voice failed him, cracking pitifully as you grabbed his bouncing chest at the very same instant you brushed against his sweet spot, digging your fingers hard into the plush skin. “F…f-fi…fuck.”
He squeezed his eyes shut, throwing his head back against the pillows as his resolve fully crumbled. The sensation of your palms pressing against his nipples was already dizzying enough, but once you took the hardened buds between your fingers and pinched, he was a complete goner. He made no effort to keep counting even when you didn’t stop rocking your hips, instead letting his mouth hang open uselessly, spilling out another long, shameless moan that made goosebumps rise on your skin. Just a few strokes in, and he was already so far gone.
You let him get away with it for a bit longer, taking the time to admire his dark, messy curls sprawled out against the white pillowcase, even fluffier than usual from all his tossing and turning. Everything about him was so soft. His pecs spilled out between your fingers as you pawed at them, his full cheeks were flushed red and his lips were swollen into a cute, puffy ring after how much he’d nibbled on them. It took all your willpower to not give in to the irresistible sight and keep pounding into him until his head really was too empty to think anymore.
“So pretty, Binnie. Wanna keep you like this forever,” you murmured. You could feel his heartbeat pick up over the praise, pulsing faster under your palms. Then, all at once, you forced your hips to stop and snapped him out of his daze yet again. “But a pretty boy like you still needs to listen.”
“M-mmph,” he mewled. His body chased after your touch, protesting the loss before he even fully realized what was going on. “N-no. Sorry, I’m sorry. Don’t stop, please?”
“I only stop when you stop.” Your hum was deceptively sympathetic as you watched him fist the sheets in frustration, biceps bulging and chest heaving. His throat bobbed as you closed his slack jaw and tilted his chin up, brushing your thumb delicately over his tiny scar to urge him to look at you. “What’s got you so distracted, hm? What’s on my baby’s mind?”
He forced his eyes open again, so dark that you could see yourself reflected in them clear as day. They gave you your answer before he even said it.
“You,” he breathed. It was a reply he’d normally be proud of, but with the way you were staring him down from above, he couldn’t stop a sheepish giggle from rising in his throat, lips twitching at their corners and cheeks bunching up.
“Me?” you echoed. “Or this?”
You slid your strap back inside him in one sharp thrust, angling it so that the tip rolled against the roof of his walls and hit his prostate perfectly. He cried out as if on command, high-pitched and sweet. “Ah! Yes, r-right there.”
Even your own rules were becoming less convincing of a reason to deny him when you knew those were the kinds of sounds you’d be missing out on. But you were on a mission, today; teaching Changbin how to multitask, or, toying with his body until he couldn’t take it anymore—whichever came first.
“There’s my answer.” You feigned disappointment, flattening your palm against his stomach and pressing down right around where you guessed the head of your strap had reached inside him. “All you care about is being filled up, huh, baby?”
“N-no, no.” His hand pawed around blindly in the sheets for a moment before he found you, grabbing on to your wrist and pushing your hand harder against the soft pudge of his tummy. You weren’t sure if he’d done it just to gain some kind of stimulation, or because he was just aching to be as close to you as physically possible, but to his credit, he forced himself not to lose his train of thought even as the sensation had his eyes rolling back.
“Binnie’s a good boy. ‘M only like this ‘cause of you. I need you, please.”
He was right; he was such a good boy. He could forget how to count, forget how to close his mouth, forget how to listen, but he’d never ever forget how to say please. That was something you didn’t have to teach him. Still, you didn’t give him what he wanted just yet, instead tracing gentle patterns on his skin, just above where his cock was leaking out tiny drops of precum. It took a few moments for him to connect the dots, but finally, he rasped out the word you were looking for.
“Four…n-no, wait, it was five,” he stammered. “Please, don’t stop, please?”
“Good boy,” you cooed. Grabbing hold of his thighs, you used all your strength to pull your bodies closer together, lifting his legs and settling them around your waist for easier access. A cute, flustered giggle escaped him as he scooted down the mattress, melting into a sigh of pleasure when you were able to nestle your strap even deeper inside him than before.
His fingers sank into the sheets, gripping them so tight that you could see the muscles in his forearms flexing. “S-six,” he gritted out. “M-mm, feels so good. More, please, more.”
The sound of skin on skin began to fill the room as you finally picked up your pace like Changbin had been begging for. You made every stroke count; deep and heavy, pulling out until just the head of your strap was left teasing his entrance, then sliding all the way back inside until your hips smacked against the back of his thighs. The new position immediately took a toll on him, you could tell by the growing lapse in his counting. Every time you left his walls fluttering around nothing, it took a few seconds before he remembered to call out the next number, just so he could feel the relief of you burying the toy inside him again.
“Nine,” he gasped. The building pressure in his core drained his concentration little by little, making for an adorable show of reactions for you the more his self-control slipped. Every pretty sound he made rang out in the thick, hot air around you, unrestrained and heavenly. Your gaze fell from his blissed out face to where his dick laid half-hard against his stomach, bouncing from the impact of your movements. It gave you an idea.
Changbin choked on his next number as you brought your hand to his head, scooping up the tiny beads of precum and curling your fingers around it. You felt him swell in your grip almost instantly, and when you began to pump his cock along with your thrusts, he fully throbbed in your hands with a fresh wave of heat.
“El-elev—ngh,” he slurred out, barely intelligible. “Three…four. No, t-ten.”
“Four? Ten?” you mimicked. “That’s not right, baby. Try again.”
You swirled your thumb around his leaking tip, effectively fizzling out the last of his thoughts. It was hopeless; the strokes of your hand were mixing up with the pump of your strap, muddling his everything together until he couldn’t distinguish between the pleasure. “Six…n-no, ah. Good, so good. I c-can’t—”
“You usually listen so well, Binnie,” you frowned. “What happened to my good boy?”
Changbin bit down on his bottom lip, so hard that you worried his cute little fang might dig deep enough to split the plush skin. You timed your thrusts seamlessly with the rhythm of your hand, sinking down on his cock as you pulled out of him, and gliding back up his length as you bottomed out again.
“Y-your hand,” he whimpered. “It’s confusing me, I can’t…feels too good.”
“Should I stop touching you, then?”
You released him from your grip, letting his dick fall against his stomach to twitch over the loss. His hips surged up in protest, a soft whine spilling out of him and growing even louder when you pulled your strap out of him in one fluid motion, leaving his walls clenching wildly for you.
“No, no,” he groaned, locking his ankles around your waist to try and bring you closer. “Please, ‘m so close. Please.”
Taking the silicone into your hand, you lined it up with his entrance, pressing the tip just hard enough against him to add an exhilarating pressure. His reaction didn’t disappoint; a full-body shudder, rippling through his muscular thighs, making his chest jump and his biceps tighten.
“You want it, baby?” you asked sweetly, circling the head of the toy around his rim.
“Yes, yes, please.” The way he rolled his body was nothing short of sinful, you almost gave in right there. His tiny grunts of frustration only grew the more your strap prodded at his hole, teasing the sensitive nerve-endings without giving him the satisfaction of slipping back inside. “Please, b-been so good. Give it to me, please.”
“I know, baby.” You inched the toy away before he could get any real stimulation out of it, brushing its slick tip against his inner thighs in a playful taunt. “Just tell me where we left off, and I’ll fuck you like a good boy.”
Changbin shot you a look of pure helplessness, eyebrows scrunching in dismay as it dawned on him what you wanted.
“I-I…I don’t remember,” he mumbled, not even trying to muster up a guess before he surrendered. “I got it all mixed up, I can’t—”
“I thought Binnie was smart?”
He squeaked in protest as you pulled your strap completely away with a click of your tongue. “I am! I a-am. Again, please? I’ll try again.”
It wouldn’t make a difference, he knew that as well as you did. But he said it anyway, as a last resort—anything to feel you stretching him out again, anything to hear you whisper honeyed praises into his ear as he fell apart for you.
“You’re hopeless, baby,” you murmured, brushing back his fluffy bangs to reveal his eyes. They were wide as moons, full of desperation and welling up with tears at their corners.
“Please.” The droplets spilled over before he could blink them away. You softened as they trickled down his flushed cheeks, darkening his eyelashes and glazing over his pupils.
“You’re crying?” Gently, you cupped his face to soothe him. You could feel the heat radiating off his skin as you wiped away his stray tears, only for new ones to take their place again. “You want it that bad, angel?”
The wet gleam in his eyes spoke for itself, but still, he managed a tiny nod.
“You look so pretty like this,” you marveled, rubbing the pad of your thumb under his eye to scoop up another bead trailing down his face.
Despite himself, Changbin perked up over your words. “Pretty?” he sniffled.
“Mm.” A mix of lube and tears smeared his skin as you tilted his chin up, looking him straight in his eyes to admire the fresh droplets gathering at their edges. They caught the light like rhinestones, a visual captivating enough for you to give him anything his heart desired in that moment. “Beautiful boy. My pretty little crybaby.”
Changbin’s nose scrunched up, a shy, downturned smile tugging at his lips. He knew there was a condescending hint to your words, but when they were spoken so sweetly, when you called him pretty in that voice—when you called him yours in that voice—he could do nothing but melt.
“Seriously. Don’t you like me too much?” He pawed your hand away in embarrassment, but you didn’t miss how his face lit up, visibly yearning for more compliments, for your approval.
You let out a fond hum. Just like that, you’d found the key to keeping him motivated. He sucked in a sharp breath of surprise as you took hold of your strap, realigning it with his entrance.
“Let’s try again.” You tapped the head of the toy against his rim, just to bask in the way it made him wriggle in the sheets. “Show me how good you are, baby.”
He nodded again, still timid, but revitalized by your encouragement. His lips puckered into a cute little rosebud for you, and with a soft giggle, you took the hint, leaning down to press them against yours. The wet trails on his cheeks cooled your skin as you kissed him, slowly, dragging your lips past the corner of his mouth to kiss away away his tears, too. His shaky sigh fanned out around you, warm and feather-light as you sank back into him, all the way to the hilt of your strap.
“One.”
You rested one hand on the mattress, bringing the other back to his dripping cock. It was still fully hard even after being neglected so long, jerking gratefully in your palm as you began to stroke it again.
“Two. Th—mm—three.”
“That’s my boy,” you praised. “I know you can do it for me.”
You matched the rock of your hips with the glide of your hand, just as you’d been doing before. It immediately took effect on Changbin, slurring his speech and making his face scrunch up. But he kept trying for you.
“Four…ah, please.”
“Good boy. Keep it up, okay?” You rolled your strap against his sweet spot, teasing it repeatedly with the curved silicone tip before pulling out again.
“Five. F-five, again, please.”
You indulged him. “Doing so well for me, Binnie,” you crooned, swiping your thumb over his swollen head and making his hips buck. “My smart boy. My good boy.”
“Mm, mm. Binnie’s smart. Your s-smart boy,” he agreed. He was so simple; spurred on by your doting, even as that familiar, hot coil in his abdomen started nipping at the edges of his mind again. “Your g’boy…ngh. So good.”
More tears trickled from the corners of his eyes as he squeezed them shut, trying to get ahold of his thoughts long enough to get out the next number. You were being so patient with him, so kind to him, he had to do his best for you.
“Six,” he whimpered. A new wave of droplets spilled over, this time, because the pleasure was growing too strong to bear. You picked up your pace as you drank in the addictive sight; his clenching stomach, tear-stained face, his bulging muscles grasping at the sheets. He deserved it when he took it all so well and looked so good doing it.
“Seven, eight—close! I c-can’t—!”
“Almost there, baby. Just a little more,” you encouraged him. “You’re so perfect like this. Don’t you wanna show me how pretty you look when you cum for me?”
His dick stiffened in your hand, both over your words and the way you wrapped your palm around its sticky tip. The squelching noise that each roll of your hand created started to mess with his head again, distracting him from his count.
“Eight…e-eight—ah, please. Please, please, please. ‘M gonna—”
“C’mon Binnie, you’re so close. Don’t give up now.”
“Ten, n-no, nine? Nine—?”
He clenched his jaw, hips surging up and walls tightening around your strap like he was afraid you might pull out at any moment. It was useless. No matter how desperately he tried to concentrate, the pressure in his stomach consumed everything else, emptying his mind a little more each time you filled him up. “S-sorry, ‘m sorry. It’s so good, t-too good.”
“I know, baby,” you purred, sensing that he’d reached his limit. “It’s okay, let it all out for me.”
Changbin’s words melted into moans again as you thrust into him with more force, giving him no chance to brace himself for each dizzying stroke, let alone keep track of them anymore. He wasn’t sure if it was because of how tortuously long the buildup to his climax had been, but the sensation creeping up on him felt more intense than usual, like a dam of water waiting to break. Everything felt amplified—the drag of the silicone along his ridges, the sensitivity of his nerve-endings at every point of contact, the dancing of your fingers around his cock—it was all dialed up to a hundred.
You thumbed at his leaking slit, unprepared for just how powerful of a reaction it’d elicit from him. He stiffened beneath you as a jolt of pleasure shot straight to his core, breaking the dam loose all at once.
Changbin’s broken sob sent a shiver down your spine. He arched his back off the mattress as his orgasm racked his body, spurting his release against the pad of your thumb. You stopped rocking your hips to admire him, completely taken by the sight unfolding before you. His cock pulsed in your hand with every wave of pleasure that passed through him, spraying out more cum than you’d ever seen before. It was noticeably different from the sticky white ropes you were used to—watery and messy. The streams splattered against his contracting stomach, glazing his skin with a translucent layer of fluid and coating your hand in the process.
He was panting by the time the last few drops of his release spilled from his aching head. Even as it dribbled down his hips and sank into the sheets underneath him, he didn’t quite understand what had happened, far too preoccupied with the tiny aftershocks rippling through his body.
Your fingers uncurled from his dick, letting it fall limply against his ruined stomach. He flinched as you ran your hand over his soft, soaked flesh, still hypersensitive after the climax that had shaken him more intensely than either of you bargained for.
“Look at that, baby,” you marveled, holding up your dripping fingers for him to see. “Your dick’s crying, too.”
Changbin’s eyes fluttered open, shiny with residual teardrops. They widened when he registered why his skin felt so wet, why the bed beneath him felt so sticky and warm, and why his muscles felt deliciously sore, like when he stretched them after a good workout. His cheeks flushed beet red, legs squeezing around your waist in a pointless attempt to cover himself.
“Oh my God. I c-can’t believe—” His face was hot with shame as he buried it into his palms, muffling a noise that sounded something between a giggle and a miserable wail. “I didn’t mean to. W-wait, don’t look, please.”
His babbling trailed off when you stroked his stomach, a gentle touch that masked how fast your heart was still racing over the effect you’d had on his body. You wanted to make it happen again.
“That was intense,” you murmured. “Are you okay, Binnie?”
He couldn’t find the courage in him to reply, too mortified to face you after making such a wreck of himself, too dazed to string a proper sentence together. All he could manage was peeking out shyly between his fingers.
You rested your hands over his to tug them away from his eyes and get a look at him. A soft objection rumbled in his throat, but he let you, anyway, mustering all his self-control to not shove his face in the pillows and hide away from your stare.
“M okay,” he reassured you quietly.
“Felt good?”
“Good,” he mumbled. “Too good. Wh-what did you do?”
“Ask yourself that, baby,” you drawled. Changbin shivered as you gave his hips a squeeze, an embarrassing mewl slipping past his lips when he clenched around your strap reflexively and realized it was still nestled deep inside him. “Look at the pretty little mess you made for me.”
Changbin let out another low whine. He gave up on maintaining eye contact, turning his head to squish his heated cheeks against the pillow. “Binnie’s shy.”
“You’re so cute.” You ran your fingers through his messy curls to ease his mind, relieved when you felt some of his tension relieve under your touch. “Do you have any idea how hot that was?”
Your words seemed to snap him back to his senses, clearing the fog in his head and reminding him of how he’d even reached this point in the first place. He made a tiny grunt of effort as he scrambled to prop himself up on his unsteady elbows, eyes widening with guilt. When he spoke, his voice was shot, edged with a delicious rasp after how much he’d strained it.
“I…” he giggled nervously. “I-I lost count again.”
You puffed out a light laugh of your own. Even you had completely forgotten about keeping track of your thrusts after watching Changbin fall apart so beautifully for you. Your little experiment may not have worked out, but you were far more interested in the outcome, anyway.
“Guess we’ll just have to keep practicing, yeah? Until we find out how many it takes for you to cum for me like that again.”
