Your thighs were starting to burn.
You’d been riding Nagi for who knows how long. The rhythm had gone from eager to lazy, your hips rocking slower, more out of habit than lust now. He barely even looked at you. Just laid back on the couch, one hand behind his head, the other loosely gripping his controller.
Eyes glued to the screen.
Not on you.
Not on how your cunt squeezed around him with every bounce. Not on how flushed and sweaty you were, clinging to the curve of his broad chest with trembling thighs.
You huffed, rolling your hips once more, but his reaction was minimal—a distracted grunt, a faint twitch of his fingers around the controller.
That was the last straw.
“Gosh,” you muttered under your breath, slowing to a near stop. “That’s boring.”
His fingers froze.
The controller clattered to the floor.
Silence.
You blinked. “Wha—”
Before you could finish, you were flipped.
Hard.
Your back hit the couch cushions with a muffled thud, and Nagi was suddenly on top of you, towering, eyes heavy-lidded and unreadable—but something dark had sparked behind them.
“Boring?” he echoed, voice low, dangerous. “You said riding my cock is boring?”
You swallowed. “I-I didn’t mean—”
His hand wrapped around your throat—not tight, just enough to make your pulse jump.
“I was letting you be in control,” he said, calm but sharp. “Didn’t know my princess would act like a brat about it.”
He didn’t give you time to respond. His hips snapped forward in one brutal thrust, burying himself to the hilt in one go.
You gasped—choked, actually—arms flying to his shoulders as he filled you so fast it made your walls clench tight around him.
“Oh,” he said with a lazy smile. “That got your attention.”
Then he moved.
Fast. Deep. Merciless.
His cock pounded into you, every thrust angled to hit your sweet spot with maddening precision. The wet, slick slap of skin echoed loud in the room, mixed with the sound of your stuttering moans.
Your nails dug into his arms. “S-Sei—!”
He didn’t stop.
Didn’t even blink.
“You’re bored?” he muttered, pulling out halfway just to slam back in harder. “Let me fix that.”
You couldn’t even catch your breath.
Your legs were spread wide, trembling as he fucked you open like he was trying to ruin you—his full weight pressing you down into the couch, one hand gripping your thigh and pinning it up, the other bracing near your head.
“You sound pretty into it now,” he muttered, voice breathy as he drove into you, pace relentless. “Not so bored anymore, huh?”
You were trying to speak, but your words broke apart into whines—your body trembling from the overstimulation. You could already feel your orgasm rising way too fast, heat coiling deep in your belly, your clit throbbing with every deep stroke.
And he knew.
“Ohh, you’re gonna cum?” he cooed mockingly. “Didn’t even ask for permission. Tch.”
His hand slid between your bodies, and he rubbed your clit fast. Not gently—mean. Two fingers circling harshly, forcing the orgasm to come crashing into you like a train.
You came with a sob, body arching, eyes rolling back, cunt clenching hard around his cock.
But he didn’t slow down.
“You thought you were done?” he said flatly. “Nah.”
He pulled out and flipped you like it was nothing.
Now you were face down, ass up, exactly how he liked it.
Your arms barely held you up. Your knees were weak. Your pussy was dripping, twitching from the orgasm, and you had no chance to protest before he shoved back inside you from behind, bottoming out with a filthy squelch.
The sound you made was practically a scream.
“You’re gonna take all of it now,” he growled. “Since you were so ‘bored.’”
His hand tangled in your hair, yanking your head back as he slammed into you over and over. Every thrust forced your hips forward, made your ass jiggle, made your cries sharper. Your vision blurred. You were so overstimulated your body couldn’t keep up—hips jerking, walls fluttering around him helplessly.
“Listen to that,” he breathed against your ear. “Listen to how wet this ‘boring’ dick is making you.”
You were choking on your own moans.
“Sei, I-I can’t—too much—”
He leaned down, chest against your back, hand snaking under you again to rub your clit mercilessly. “You can. You will.”
You came again—harder this time. Your body spasmed, thighs quaking. But he wasn’t done. Not even close.
He kept going.
Using you.
Dragging orgasm after orgasm out of your overstimulated body until tears blurred your eyes, until you were babbling nonsense, hips jerking from how raw and sensitive your cunt had become.
And finally, when your legs collapsed under you and you were trembling, breathless, face buried into the cushions—he finished.
With a groan, he buried himself to the hilt and came deep inside you, thick warmth flooding your insides, pulsing through your wrecked cunt.
He stayed there, cock still twitching inside you, as you whimpered beneath him.
“Still boring?” he asked lazily.
You didn’t answer.
Couldn’t.
You were too wrecked to speak.
He chuckled under his breath, pulling out slowly, watching your cum-dripping hole clench around nothing.
Then he leaned down and whispered one last thing:
“Next time, don’t talk shit.”
