Karl hooked his hands under his knees to spread himself for Sapnap.
He was sensitive, coming down from the last orgasm (his fifth of the night, if he was counting correctly), spit and cum smeared all over his hole and thighs. Miraculously, he was ready for more.
Usually after two or three orgasms, his partners called it good and tapped out—if they even got him there. But knowing Sapnap was here until Karl was satisfied awakened something inside him that he’d never indulged in because it felt too selfish of him. Sapnap didn’t care that he was needy or insatiable. He wanted him because he was needy and insatiable.
Sapnap slid inside him like he always did: steady and unrelenting and just this side of too much. His previous orgasms had made Karl tighten up, but they were both slick with his cum, so the head of Sapnap’s cock found its way inside easily.
Karl felt scrubbed raw in the best way. It was like all his nerve endings were exposed and on fire, every slow inch of Sapnap’s dick into him feeling like heaven and hell all wrapped up in one.
One his hips were flush to Karl’s, Sapnap dropped onto his elbows on top of him, squishing him. Sapnap let out a breath and whispered, “How many more do you want to try?”
Karl blinked sleepily up at him, trying to get used to the feeling of a dick in him so soon after cumming. “What?”
Sapnap chuckled and brushed the hair off Karl’s sweaty forehead. Karl pressed into the touch, earning himself a kiss on his nose. “I mean, how many more times do you want to cum tonight?”
“Oh.” Karl unconsciously clenched at the question, and Sapnap grunted. “Oops. Sorry.”
Sapnap laughed again, thumbing across Karl’s mouth fondly. “Don’t apologize. Never apologize for that.”
Blushing, Karl nodded. “Um. I’ve never done more than seven in a row, but I don’t think I’m ready for that tonight.”
“Okay, baby.” Sapnap sat up, pulling Karl’s legs around himself as he went. Karl just followed the movement of his steady hands, trusting him to find a comfortable position for both of them. “I won’t get you past seven. How’s your dick?”
Karl snorted. “Great, how’s yours?” Sapnap leveled him with an unimpressed look, pinching his thigh harshly. “Ow! Stop it! Sorry! I’m sorry! It was right there.”
“I meant,” Sapnap said, leaning over Karl and pushing his knees back so he was fully exposed, unable to even squirm under his gaze. That look made him feel small, like an insect, or at least like a misbehaving puppy at the end of his leash. The thought sent fresh heat through Karl’s tummy. “How sensitive are you? If I try to use the wand on you again, will you try to rip my head off or scream bloody murder? In a bad way, of course.” He grinned, all sharp teeth and fire. “I’m fine with you screaming and clawing at me because you can’t handle the pleasure.”
Karl swallowed harshly, fighting down a whimper. He shook his head. “I’m okay. Really sensitive, but not in a bad way yet, I don’t think. I can safeword if it’s too much.”
“Good boy,” Sapnap purred, ducking down to kiss Karl.
The older man tipped his chin up, trying to get his tongue inside Sapnap’s mouth. He managed it with limited success until Sapnap finally moved and Jesus H. Christ.
Karl’s head fell back onto the pillows, eyes rolling back as the head of his boyfriend’s dick sawed across his most sensitive areas. He was certain that dick was custom made just for him—not overly large, but the head was thicker than the rest and curved in a way that mercilessly drove across his g-spot without even trying. It was a lot on a regular day. Now, after so many orgasms, it made him dizzy with pleasure.
It was almost too much. Karl’s legs shook in their position around his boyfriend’s hips. He was sensitive to the point of pain, but holy shit he’d never felt so good.
“That’s it, baby,” Sapnap purred. Karl felt him pop a little kiss onto his upturned chin as he didn’t seem to pay any mind to the way Karl was fucking up into each of his gradually speeding thrusts. “Take me so well.”
One thrust jarred Karl so hard his teeth clacked together as he moaned. His hands scrambled to Sapnap’s shoulders, his fingernails digging in as he tried to cope with the pleasure racing through him.
Sapnap hissed as his nails scraped against his skin. Then he laughed. “Kitty’s got claws, huh? Does it really feel that good?”
Karl shuddered, loosening his grip. “Sh-shut up. You’re such a dick.”
“Oh?” Sapnap sat back up, pulling Karl’s hips to him with ease like he wasn’t a fully grown man rather than a toy for him to throw around. Karl blinked open eyes he hadn’t realized he’d shut. His boyfriend was crouched over, seemingly unbothered by the tight little cunt wrapped around his dick. The sight of him so composed sent something dark curling in his gut. “I see that attitude’s coming back. Let’s see if we can’t do something about that.”
Karl didn’t have the chance to ask what he meant before the magic wand was back, drawn between them and pressed firmly against Karl’s swollen clit. He bit his tongue to keep from making a noise. It wasn’t even on—just the sight of it sent a flash of recognition through his fried nerves.
“Hold this for me, would you, babe?”
It wasn’t phrased like a command, but Karl knew it was. Sapnap had that look in his eye again, the one that reminded Karl of the killer he’d been so fascinated by. The killer who stalked his prey. The killer who never stopped until he got what he wanted.
The killer who’d reached into his chest and grasped his heart like it was already his to begin with.
Karl obeyed. He grabbed the toy with both hands, too shaky to trust himself with just one. Wide eyes searched Sapnap’s face, waiting for a cue to turn it on.
Sapnap just tipped back his head and laughed. “God, look at you! Those wide innocent eyes asking permission like you didn’t just cum those pretty brains out two minutes ago.” He shook his head fondly. “Go ahead and turn it on, baby boy. Whatever speed you want. Call it a treat for being so fucking precious.”
Karl blushed—Sapnap’s compliments, even sneered in bed like that one, were always more earnest than any endearment he’d ever heard. It was hard to imagine he didn’t mean it.
A flick of the switch and the toy buzzed to life under Karl’s hands. He gasped like he was starved for air, resurfacing after an hour under the sea. His thighs tensed, shuddering as Sapnap plowed into him cruelly.
Sapnap must’ve caught the tightening of Karl’s cunt around him. “What was that? Did you just cum again?”
Karl whimpered, biting his lip for a moment. “Maybe? I-I can’t tell. It’s all… all running together. Oh my god, Sapnap—”
“Fuck.” Sapnap’s head fell back again, exposing the long line of his throat as he groaned. His Adam’s apple bobbed gently. Karl wanted to bite it. “You feel so good clenching around me. This toy was the best investment I’ve ever made. Think it might be an even better gift for me than it is for you.” His head dropped, dark eyes searing into Karl where he panted and yelped under him. “Might take advantage of you like this. Tie you up, put that toy on your dick to keep you all tight and wet for me, come in and fuck you whenever I want. You’d probably lose your damn mind with how much you came from it, but that would just make it easier for me to come in and have my way with you however I wanted. And you couldn’t have a say in any of it.”
The thought stole Karl’s breath.
In his past, with his ex, with other people, he’d needed complete control. Even a second where he didn’t have all his faculties could mean someone would hurt him, that he could lose more than just his dignity.
It wasn’t like that with Sapnap. It never was.
Karl had the sudden thought that he’d feel safer tied up in a serial killer’s bed than he had in his apartment with his ex. He found himself laughing.
Sapnap slowed down. “What’s so funny, princess? Think I won’t do it?”
“I know you will.” Karl’s voice was scratchy. He shuddered again, his hips finally giving in and rolling up against his boyfriend’s to get his previous pace back. “I hope you will. I’m just laughing at my-myself.”
“You wouldn’t be, if you could see yourself the way I see you.”
Karl took a breath. “I trust you,” he admitted. “I think I trust you more—more than I’ve trusted anyone.”
Sapnap smiled, this one softer than all the rest. One of his hands left his firm grip on Karl’s thighs to tweak his cheek. “You’re cute.”
Karl rolled his eyes. His retort was cut off by Sapnap grabbing him under the knees and pushing them back, spreading him open that much further as he thrust in with abandon.
Karl lost himself in the moment. His head was swimming, unable to focus on any one thing for too long. Just when he thought the feeling of the wand vibrating against his dick was getting too much, Sapnap would shift inside him and pull his focus back.
At some point, Sapnap braced his hand on Karl’s collarbone to drive into him harder. He wasn’t putting his weight into it, but Karl felt it pushing the breath from his lungs nonetheless. He itched to push that hand higher, for those fingers to wrap around his throat. To steal his breath.
“You close?” Sapnap’s voice drew him from thoughts of rough fingers digging into his neck. “You got all quiet on me.”
Karl nodded. He was close, that wasn’t a lie, but it wasn’t the reason for his silence. The wand was buzzing relentlessly against his dick and Sapnap was practically a machine with his precise, even thrusts, but neither of those things were the cause of his reverie.
Sapnap slowed his pace and Karl whined. “What is it, baby? Need me to slow down?”
“No, no!” Karl cried. He dug his heels into the backs of Sapnap’s thighs, spurring him on. “Don’t stop, please.”
“What is it, then?”
“I…” Karl bit his lip, too ashamed to ask. He knew Sapnap wasn’t one to judge. Considering how he spent his nights, every judgment he cast should come with a grain of salt. But he still couldn’t bring himself to say it.
Instead, gasping with every thrust Sapnap made into him, he grabbed Sapnap’s hand from his chest and shoved it around his throat.
After a moment, Sapnap got with the program, grinning evilly down at Karl. “Oh yeah? Is this what you wanted?” His fingers dug into the sides of Karl’s throat, making his head go fuzzy. Karl nodded desperately, eyes slipping shut. Sapnap squeezed tighter. “Ah, ah, ah. Look at me, slut.” Karl’s eyes flew back open, a whine getting caught in his throat. “There you go. Such a good boy, wanting his master’s fingers around his throat before he can cum. Sweet little whore, aren’t you, baby?”
Oh, God. This was everything Karl had ever wanted and more. He whined again and Sapnap eased his grip, so the sound actually came out this time. “Yes!” Karl gasped, his voice strained and desperate. “Yes, yes! Please, master, more!”
Sapnap chuckled, low and pleased. “Good fucking boy, Karl.”
The wand turned up to its full intensity and Sapnap squeezed his neck until Karl was struggling to breathe.
And then he was flying.
He came around Sapnap, legs shaking and mouth hinged open on a silent scream. He made no noise, but every inch of his body trembled, overcome with the feeling of cumming like this, with Sapnap in charge of his pleasure and his air supply.
He’d never cum without breathing before, but now that he had, he wasn’t sure he’d ever be able to cum with breath in his lungs ever again. He was hot all over, straining with lack of oxygen, his chest hitching to get breath and only managing a gasp every couple seconds. It wasn’t nearly enough to satisfy the aching in his lungs, but it fueled the aching in every other part of his body.
Sapnap’s hand ripped away from his throat. Karl gasped and immediately began sobbing. Sensation returned to him—he hadn’t realized how zoned out he’d been while he couldn’t breathe—and he scrambled to get the vibrator away from his dick. Sapnap slowed his thrusts but didn’t stop, grinding deep into Karl as he sobbed.
Sapnap was speaking, Karl realized when the blood stopped singing in his ears. Soft, pleased affirmations made only for Karl. “Such a good boy,” he was saying when Karl finally tuned in. “So good for me. Look so gorgeous cumming for me like that. I love feeling you lock up around me. Like you were built for me. So perfect, love. So good for me.”
“S-Sapnap,” Karl bit out through tears and snot. He grabbed for Sapnap, pulling him closer, craving his body heat.
“Shh, I’m here.” The toy disappeared, discarded somewhere on the bed. Karl didn’t miss it; he now had a love-hate relationship with the thing. Sapnap stopped his thrusts, holding Karl close as he shuddered. “You did so good, baby, showing me what you wanted. Are you done? Want me to pull out?”
Sapnap made a move to do that, but Karl grabbed him, locking arms and legs around him in a koala-grip to keep him from leaving. “Don—don’t! D-don’t stop! Please, I want more.”
Sapnap frowned. “Baby, are you sure? You’re crying.”
“I know, I know.” Karl sniffed to prove his point, reaching up to wipe his face with the back of his arm. “Good tears. Want you to finish in me. Please.”
“Oh, fuck,” Sapnap said, looking like Karl had just punched him in the gut. Maybe he had if the way his dick twitched inside Karl meant anything.
“I’m serious,” Karl said. “I didn’t go through all the trouble to get tested for you to not cum inside me.”
Sapnap looked about ready to fall over, but he quirked a smile and asked, “What are the odds you can cum again?”
Karl returned his smile, flinging his arms over his head and melting into the mattress. He was sure he looked a mess: tears and spit drying on his face, hair wrecked, neck mottled red from Sapnap’s grip. But in that moment, with Sapnap looking at him like that, he felt like a deity. “What are the odds you can make me?”
Sapnap scowled and pulled his dominant persona around himself like a shroud. He grabbed Karl’s wrist, squeezing hard enough for his bones to grind together, and made him grab Sapnap’s forearm. “Hold just like this,” he instructed coolly, no room for argument. Karl closed his fingers around the muscled arm. “If you let go, that’s the same as calling yellow. If you let go and tap the bed, that’s red. As long as you’re holding on, I’m taking that as the greenest light you’ve ever given. Understood?”
Karl nodded. “Understood. Why not just use the lights, though?”
“Because, baby.” The hand of the arm Karl was gripping trailed up his neck, digging into the spots forming there that would turn into bruises. “I’m going to be in control of when and if you breathe. And I’m afraid of snapping your pretty neck…” He squeezed there, just to prove his point, the muscles flexing under Karl’s hand. Karl was sure Sapnap could feel his pulse thrumming below the skin and wondered if he felt the jolt his heart made at that statement. “So I’m going to cover your mouth and nose instead. Like this.” He trailed his hand up and clamped his palm over Karl’s mouth, his fingers pinching Karl’s nose shut. “Got it?”
Karl nodded.
“Good,” Sapnap purred. “Now let go. Show me what to do when you need a breath.”
Karl released Sapnap’s arm, and the hand pulled back from his face, letting him breathe again.
Sapnap dipped down to kiss him. “Good boy,” he breathed against Karl’s lips. “You’re not getting the wand again. You’re just going to cum on my dick.”
“Sapnap—” Karl began to protest.
A light slap landed on his face, not hard enough to sting, but jarring enough to shut him up. He whimpered, clenching tighter around where Sapnap’s dick was still resting inside him. “Who’s in charge here?”
“Y-you are.”
“That’s right.” Sapnap sat back up and looked down at Karl again, licking his lips as he took him in. “You just lay there and let me use you until I’m done. Are you alright to go on?”
Instead of answering, Karl grabbed Sapnap’s arm again, looking up at him pointedly with wide eyes.
Sapnap tipped his head back and laughed. His hand covered Karl’s mouth, not restricting his breath yet but enough for Karl to whimper. “God, you’re so fucked up, baby,” Sapnap said fondly. “I can’t get enough of you.”
Then he started thrusting again—long, slow strokes that stole Karl’s breath before his hand could. Sapnap shifted them, not breaking his rhythm, until Karl was halfway in his lap, arching into thrusts that dragged against every single sweet spot in his body. His eyes rolled back, and his jaw dropped open beneath Sapnap’s hand. A muffled moan announced his pleasure.
“Yeah?” Sapnap panted. “Is that it? That feel good, princess?”
Karl nodded, grabbing Sapnap’s arm with both hands, fingers digging in.
A dark chuckle. “That’s right, baby. Good boy.”
Sapnap’s fingers pinched Karl’s nose shut. He didn’t have the chance to take a breath in before Sapnap closed off his airways, so his lungs immediately jumped to breathe. When they got no air, his chest spasmed, thrashing instinctively to get free. He only gripped Sapnap tighter, begging him not to let go even as his body screamed for air.
In his flailing, he managed to kick Sapnap in the ribs. Sapnap grunted and stopped immediately, hand falling from Karl’s face to let him gasp for breath. “Watch it,” Sapnap said, rubbing the spot he’d been kicked.
Karl couldn’t laugh properly, still trying to regain his breath, but he huffed with a smile regardless. “Sorry. Couldn’t control it.”
“Hmm,” Sapnap hummed. He grabbed one of Karl’s legs by the knee and yanked him, bending and twisting his pliant body until one leg was over Sapnap’s shoulder and the other was wrapped around his waist, pinned by his arm. “Comfy?”
Karl rolled his hips, using his new position for leverage. “Mmm. Very.”
Sapnap rolled his eyes and covered Karl’s mouth again, humming in approval when Karl grabbed his arm without prompting. Sapnap was getting monosyllabic, a sure sign he was close. Karl himself was climbing that peak—or he had been, at least, before he’d kicked his lover in the throes of passion.
Sapnap pulled out slowly, dragging deliciously across Karl’s electrified nerve endings. He’d never felt so much during sex before Sapnap—it was part of the reason he’d let his ex do so many horrible things to him without any safeguards in place.
“Last one, baby,” Sapnap growled. His voice was deep and roughened from so long at work. Karl felt a little bad for him. Karl had cum… well, a lot, even if he couldn’t quite remember how many times it was by now, and Sapnap hadn’t even cum once in the time they’d been at it (which, according to Karl’s internal clock, had to be approaching 90 minutes at least). If Karl hadn’t known before that Sapnap was a gem, he sure as hell knew now. “Take a deep breath for me.”
Karl did, filling his lungs until he couldn’t anymore. Sapnap’s fingers covered his nose, removing all Karl’s autonomy. He was completely under Sapnap’s control, not even able to have a say in when—or if—he breathed.
It was terrifying.
It was freeing.
There’s no one else he would trust with this, he realized suddenly. In the short time he’d known Sapnap, he’d proven to be a fiercer friend and more loyal companion than anyone else Karl had ever met. He knew without a doubt that if it came down to it, Sapnap wouldn’t hesitate to put Karl’s life before his own. And even if he didn’t, if he decided this life was too dangerous and cut him loose by blade or by word, then Karl trusted Sapnap in that, too.
The fingers of Sapnap’s free hand dug into Karl’s thigh, making him want to whimper in pain but he couldn’t. Sapnap leaned over him, bending him in half. Karl blinked open eyes he hadn’t realized were closed.
“You better fucking cum if you want to breathe again, baby.”
Karl whimpered—or he would have, if he could make any noise other than desperate, muffled squeaks in the back of his throat.
Every thrust jarred him, rattled his bones, made his liquified brain slosh around in his otherwise empty skull. Sapnap was plowing into him so roughly, he knew he wouldn’t have been able to catch his breath even without the hand on his face.
He held out as long as he could.
Right when the spots started clouding over his vision, Karl let go, shattering to pieces as unconsciousness took over.
He missed it when Sapnap came inside him for the first time.
His boyfriend had been in shambles afterward, overwhelmed by making Karl pass out and by being able to cum inside him for the first time.
Karl soothed his concerns, drawing him between his legs to clean up his mess before they fell into a long, hot bath together.
