"Yours... only yours, Sanemi-san."
He gasps out between moans, his eyes glazed with lust and submission.
"Damn right you are."
Sanemi remove his fingers and positions himself at Giyuu's entrance, the head of his cock pressing against the tight ring of muscle. Sanemi slowly starts to push in, his hands gripping Giyuu's hips hard enough to leave bruises.
"Fuck, you feel amazing."
He groans deeply, watching as his cock disappears inch by inch inside Giyuu's tight heat.
"So big... so deep!"
He moans loudly, his walls clenching around Sanemi's thick length. His body adjusts to the stretch with obvious pleasure.
"Taking me so well... such a perfect hole."
He bottoms out and stills for a moment, letting Giyuu feel every inch of him. Giyuu whimpers and squirms, trying to get Sanemi to move faster.
"Impatient, aren't we? You'll take what I give you."
He pulls almost all the way out before slamming back in roughly, setting a punishing pace. The bed creaks under their intense movements, the sound of skin slapping against skin filling the room.
"Ah! Yes! Harder, Sanemi-san!"
His cock bounces against his stomach with each thrust, precum dripping down. Sanemi grabs Giyuu's legs and puts them over his shoulders, changing the angle to hit his sweet spot directly.
"You're getting tighter... I can feel you squeezing me."
He growls, sweat dripping down his muscular chest as he pounds into Giyuu relentlessly. Giyuu's eyes roll back in ecstasy, his mouth hanging open as he struggles to form words.
"I'm close... so close...!"
His body starts to tremble uncontrollably, signaling his impending orgasm. Sanemi suddenly stops and pulls out completely, leaving Giyuu empty and confused.
"Not yet. I want you to beg again."
He smirks cruelly, stroking his own cock as he watches Giyuu's desperate expression.
"No, please! Please don't stop!"
He reaches for Sanemi desperately, his hole twitching around nothing.
"Beg properly and I'll let you cum. And maybe I'll consider letting you have my cum inside you."
Giyuu's cheeks flush red with embarrassment, but his need overpowers his pride.
"Please Sanemi-san, let me cum on your cock. Fill me up with your hot cum. I need it so badly... I'll do anything."
He spreads his legs wider, completely exposed and vulnerable. Sanemi's eyes darken with lust at Giyuu's desperate pleas.
"Good boy. That's exactly what I wanted to hear."
He thrusts back in without warning, resuming his brutal pace.
"Now cum for me, Giyuu."
Giyuu screams as he's filled again, his orgasm hitting him like a tidal wave.
"Sanemi! Yes!"
His cock spurts cum onto his stomach and chest, his body convulsing with pleasure.
"Fuck... you're squeezing me so hard!"
He continues thrusting through Giyuu's orgasm, chasing his own release. Sanemi growls deeply as he feels his own climax approaching, his movements becoming erratic.
"Gonna fill you up... make you leak for days."
He leans down to bite Giyuu's neck again, marking him as he thrusts in deep one last time. Sanemi's hot cum floods Giyuu's insides, filling him to the brim. He grunts and shudders through his intense orgasm.
"Take it all... every drop."
He stays buried inside Giyuu, panting heavily against his skin. Sanemi finally pulls out slowly, watching with satisfaction as his cum drips from Giyuu's hole.
"You're such a mess now, Giyuu."
He smirks and runs his fingers through the mess on Giyuu's stomach, gathering some cum on his fingers. Giyuu lies there, exhausted and filled with Sanemi's seed, his body trembling from the intense experience.
"Clean this up with your mouth."
He brings his cum-covered fingers to Giyuu's lips, a commanding look in his eyes. Giyuu opens his mouth obediently, sucking Sanemi's fingers clean with a soft moan.
"That's it... good boy. You taste yourself now."
He watches with dark satisfaction as Giyuu licks his fingers clean of their mixed fluids. Sanemi grabs a towel from his nightstand and gently wipes Giyuu clean, surprisingly tender after being so rough.
"You did well today. Better than I expected."
He helps Giyuu sit up and hands him a bottle of water. Sanemi pulls Giyuu onto his lap, holding him close despite his usual grumpy demeanor.
"Next time, I'll make you scream even louder."
He runs his fingers through Giyuu's hair possessively, occasionally tracing the bite marks he left. Giyuu leans against Sanemi's chest, still catching his breath. His body feels pleasantly sore.
"Rest for now. I have some work to finish."
Despite his words, he makes no move to let Giyuu go, instead pulling him closer and reaching for his phone with one hand. Sanemi scrolls through his phone with one hand while the other absentmindedly strokes Giyuu's back.
"Stay quiet and don't move. I need to check some lesson plans."
He occasionally glances down at Giyuu, a mix of possessiveness and mild annoyance in his eyes. Giyuu nods silently, feeling oddly comfortable in Sanemi's embrace despite his cold demeanor.
"You're surprisingly compliant after sex. Usually you're so... stoic."
He comments with a hint of amusement, setting his phone aside for a moment to pinch Giyuu's cheek. Giyuu swats Sanemi's hand away weakly, a slight pout forming on his lips.
"Don't give me that look. It's cute when you're not acting all emotionless."
He chuckles darkly, finding Giyuu's pout somehow endearing despite himself. Sanemi notices Giyuu's eyes closing and smirks, letting him drift off on his lap.
"Tch... Sleeping already. So lazy."
He adjusts his position slightly to make Giyuu more comfortable, his expression softening for a brief moment before returning to its usual scowl. Sanemi returns to his phone, occasionally stealing glances at Giyuu's sleeping face. He fights the urge to touch him again, instead settling for resting his hand possessively on Giyuu's thigh.
"Damn it... I should be working, not watching him sleep like some creep."
He mutters under his breath, but makes no move to wake Giyuu up or push him away. Hours pass as Giyuu sleeps peacefully. The room grows darker as evening approaches, and Sanemi's phone battery dies.
"Great... just great."
He sighs in frustration, looking down at the still sleeping Giyuu with a mix of irritation and something softer. Sanemi carefully shifts Giyuu onto the bed, laying him down before grabbing his red pen and stack of tests.
"I guess I'll do this here. Not like I can move him now."
He settles at his desk, occasionally glancing back at Giyuu to make sure he's still sleeping soundly. As Sanemi grades the tests, he finds himself distracted by thoughts of Giyuu. He circles mistakes with more force than necessary, his mind wandering to their earlier encounter.
"Focus, Shinazugawa... Focus on these shitty test papers."
He growls, trying to concentrate on his work but finding it increasingly difficult with Giyuu's presence in the bed. One student's particularly poor performance catches his attention, and he writes a scathing comment in the margin.
"What the hell is this? Even a kindergartener could do better."
He grabs another test, finding more errors that make his blood pressure rise. The more he works, the more frustrated he becomes. Sanemi finally finishes grading, though he's in a particularly foul mood now. He stands up and stretches, looking at the pile of corrected papers with disdain.
"Those idiots are going to fail my class if they don't improve."
He walks over to the bed, looking down at Giyuu with a mix of annoyance and possessiveness before climbing in beside him. Sanemi pulls the covers over both of them, spooning Giyuu from behind despite his grumpy demeanor.
"You better not hog all the blankets, Giyuu."
He mutters against Giyuu's neck, his arms wrapping around Giyuu's waist in a tight grip.
