Heeseung had you straddling his lap on the living room couch, your knees digging into the cushions on either side of his thighs, skirt shoved up around your waist, panties long gone somewhere on the floor. His hands gripped your hips hard enough to bruise, guiding you down onto his cock again and again with slow, deliberate rolls that made your eyes flutter.

“Fuck, look at you.” he murmured, lips brushing the shell of your ear. “Taking me so deep even when your boyfriend’s probably jerking off to the thought of you right now.”

You laughed at his words, and clenched around him on purpose just to hear the choked groan he let out.

“He probably is.” you said, rolling your hips in a slow grind that dragged every thick inch of him against your walls. “Poor thing. Thinks I’m at yoga.”

“Yoga…” he repeated mockingly. “Yeah. Stretching real good right now, aren’t you?”

You answered by slamming down harder, making him curse under his breath and tighten his grip until your skin whitened under his fingers.

Your phone buzzed on his coffee table, once, twice then started ringing properly. The screen lit up with “boyfie ♡” and a photo of your boyfriend smiling sweetly at the camera from last summer.

Heeseung’s eyes flicked to the screen, then back to your face.

“Answer it.” he said quietly.

You raised a brow, still bouncing lazily. “You sure?”

He reached over, snagged the phone before you could, and swiped to accept the call. He put it on speaker and held it between you, his other hand sliding up to palm your breast through your thin top, thumb flicking over your nipple.

“Hey, baby.” Your boyfriend’s voice came through. “You okay? You’ve been weirdly quiet today.”

Heeseung’s lips curled. He didn’t speak yet, just watched you sink down on him again, watched the way your mouth parted on a silent gasp.

“I’m fine.” you managed. “Just…working out.”

Heeseung mouthed the word “working out” at you with exaggerated innocence, then he finally spoke.

“She’s getting a real good cardio session in right now, buddy.”

A beat of silence.

“…Who the fuck is that?” Your boyfriend’s tone sharpened instantly.

You laughed, rolling your hips in a slow circle that made Heeseung’s cock throb inside you. He leaned forward, lips brushing your throat as he answered.

“Her personal trainer.” he said smoothly. “She’s been coming to me for… what, four months now? You should see how flexible she’s gotten.”

You bit your lip to keep from moaning outright when Heeseung suddenly bucked up into you.

Your boyfriend’s voice cracked. “What the hell are you talking about? Baby, where are you? Who is this guy?”

You leaned closer to the phone, voice sweet and syrupy even as you lifted almost all the way off Heeseung’s cock and then dropped back down in one smooth motion.

“I’m at his place.” you said simply. “Getting fucked the way you never could.”

Dead silence on the other end.

Heeseung chuckled low in his throat, the sound vibrating against your skin. He took the phone from your hand entirely now, holding it up so your boyfriend could hear every slick sound your pussy made as you rode him.

“You ever make her sound like this?” Heeseung asked conversationally, like he was genuinely curious. “All wet and desperate? Nah, you didn’t. I can tell. She’s so fucking tight right now because she’s actually getting filled for once.”

Your boyfriend made a strangled noise. “You’re disgusting. Both of you- ”

“Am I?” Heeseung cut him off, voice becoming meaner. “Or are you just mad she’s bouncing on a real dick instead of faking it for your two-minute pity fucks?”

You laughed again and reached down to rub tight circles over your clit while you kept riding him. The added stimulation made your thighs shake.

“He’s right…” you panted into the phone. “You never hit it right. Never made me come. I faked every single time. Every. Single. Time.”

Heeseung groaned at your words, hips snapping up to meet your next drop so hard the couch creaked.

“Fuck, baby…” he muttered, just loud enough for the mic to catch. “Tell him how many times you’ve come on my cock this week alone.”

“Eight.” you said immediately even though your voice was starting to tremble. “And that’s just since Monday.”

Your boyfriend’s breathing was ragged now, furious and humiliated all at once. “You’re a fucking- ”

Heeseung cut him off again. “She’s a fucking dream, man. Pussy so good that my cock never goes down.” he said. “And you’re a disappointment. Always have been. That’s why she’s here, dripping all over me while you sit there with your sad little dick in your hand.”

You moaned openly now, no longer bothering to hide it. Heeseung’s free hand slid down to grip your ass, spreading you wider so he could thrust up even deeper.

“Tell him.” Heeseung ordered, lips against your jaw. “Tell him who owns this pussy now.”

You leaned toward the phone. “You never did.” you said to him. “Heeseung does. He fucks me the way i want and need. He makes me cream all over his dick, he comes inside me every single time and I beg him for it.”

His thrusts turned rougher, each one forcing the air out of your chest.

“You still there, man?” he asked mockingly. “Or did you hang up crying?”

No answer, just harsh breathing.

“Good.” Heeseung said. “Listen close then.”

He dropped the phone onto the cushion beside you both, angling it so the speaker was pointed right at where you were joined. Then he grabbed your hips with both hands and fucked up into you hard and fast, making you cry out, head thrown back.

The wet slap of your bodies, your gasping moans, the filthy squelch every time he bottomed out, it all poured through the speaker.

“Fuck, Heeseung- ” you whined, nails digging into his shoulders.

“Come for me baby, come on.” he growled. “Come while he listens to what he’ll never have.”

You shattered almost instantly, back arching, thighs trembling, a loud moan tearing out of you as your pussy clenched around him. Heeseung didn’t stop, just fucked you through it until your vision whited out and your voice cracked on his name.

When you finally collapsed against his chest, arms wrapping around his neck, he picked the phone back up.

Your poor boyfriend was still on the line, still breathing like he was dying.

Heeseung’s voice was calm, almost gentle now. “She’s gonna stay here tonight.” he said. “And tomorrow. And probably the rest of her life. So don’t wait up.”

Then he ended the call.

You lifted your head, still flushed and a bit out of it, you smirked at him.

“Damn, that was mean baby.” you murmured.

He just kissed you, tongue sliding against yours like he was claiming every inch of your mouth.

“You loved it.” he said against your lips.

You grinned, pressing open mouthed, lazy kisses against his neck.
