where . . . You’ve been teasing your substitute teacher all week—flirty glances, drawn-out questions, bending rules just enough to stay out of real trouble.
He finally calls you out after class, locking the door behind you with that usual, amused calm. You expected a scolding… not for things to unravel on his lap.
His voice lands like a soft command, calm and knowing. You’re caught—again—gazing down at the loose line of buttons on his shirt, where a hint of skin peeks through. You hadn’t meant to stare, but there’s something about him—about Matt—that pulls your eyes before your brain can stop them.
You blink and lift your gaze, cheeks already warm, a smile tugging at the corners of your lips. “I was just… looking.”
Matt raises an eyebrow, amusement flickering in his eyes as he leans back slightly against the desk. “You sure? Looked like you were about to start drooling.” A hand flies to your chest, dramatically. “Was not,” you say, then add with a grin, “Maybe a little.”
He chuckles, something low and velvety, and begins to move around you—slow steps that feel unhurried but intentional. As he closes the distance between you both, he reaches to shut the office blinds, then twists the lock on the door with a soft click. The room dims, warmth blooming in the space between you. Your heart picks up. This is no longer casual.
“You’re a bold one,” he murmurs, his tone still light, but with an edge that makes your stomach twist in anticipation. “Or just curious?”
You tilt your head coyly, voice soft. “Can’t it be both?”
When he turns back around, his eyes settle on you like he’s making a decision. Then, with a small crook of his finger, he gestures you forward. When you reach him, his hands find your hips—firm, warm, and sure. He slowly spins you around, guiding your back gently against his chest. His touch never rushes. One slips around your waist, the other skimming down your thigh as he sits back into his chair, pulling you with him until you’re perched on his lap, back nestled fully to his chest.
His voice brushes your ear, calm and almost affectionate. “There. That’s better.”
You hum, adjusting slightly to the shape of him under you—already hard, thick, and pressing hot against the curve of your ass. You bite your bottom lip, shifting subtly as if you’re trying not to make it obvious. But you both know it’s intentional.
He groans quietly, a hand curling around your thigh. “You don’t even try to hide it.
“Why should I?” you murmur, leaning back just enough to glance at him over your shoulder. “You like it.” He looks down at you “I definitely do,” he admits, mouth brushing your skin.
His hand slides slowly between your thighs, stroking lightly over your inner skin, teasing. You gasp softly, shifting your legs open without needing to be asked. He drags his fingers up the front of your panties—already soaked—then hooks one side and gently pulls the fabric aside. You feel cool air brush your folds, your hips jerking subtly as he hums behind you.
“Look at you,” he murmurs, dragging two fingers through your slick. “Already so wet, sweetheart.”
You make a soft sound in your throat, pressing back into him more fully as his other arm wraps around your waist. His fingers stroke through your folds again, this time slower, more intentional. When he finally pushes one finger inside, you choke on a breath—his touch is just deep enough to make your thighs tremble.
“You take me so well,” he whispers, fingers working you open gently. “You like this, don’t you?”
Your head falls back to his shoulder, lips parting. “I—y-yeah, I—”
He presses a second finger in beside the first, and you arch, hips lifting slightly in his lap. His hand tightens at your waist, keeping you anchored while his fingers begin to move—slow, smooth pumps that send little sparks ricocheting through your belly. Your walls flutter around him, soaking his fingers, your thighs trembling.
“You’re perfect like this,” he breathes, his voice thick against your ear. “Such a pretty messy...oh god”
You clutch at the arms of the chair, grinding softly down against his hand, every nerve alight with want. His palm brushes your clit with each thrust, your breath catching as your thighs try to close—he stops that with a gentle nudge.
“Don’t hide from me now,” he says, pressing a kiss to your temple. “You’re so fucking pretty when you fall apart.”
You feel your body tensing, slick dripping down onto his palm, your breath turning to broken gasps. Just before you break, he pulls his fingers out slow, dragging them back over your clit once more before releasing you, his free hand already curling around your hips.
A beat later, you’re turned to face him—chest to chest—as he sinks lower into the chair. You rise onto your knees above him while he strokes himself slowly, guiding the head of his cock between your folds. The stretch is immediate. You gasp, grabbing his shoulders, fingers digging in.
“Fuck,” you whimper, hips trembling as you start to lower down. “You’re— nghh...haah– oh my God...i- c- can't—”
He slides in inch by inch, and it’s a lot—thick, hot, impossibly deep. Your walls flutter trying to accommodate him, clenching around every inch he gives you. Your knees shake slightly as your thighs spread wider, struggling to take him fully.
“fuckfuck– take it,” he murmurs, voice rough now, hand flat on your lower back, the other splayed across your hip, steadying you. “ngh—c’mon, baby—just like that—”
When your hips finally meet his, you feel stretched wide, impossibly full. You exhale a shaky moan, burying your face against his neck, lips brushing his skin as you try to catch your breath.
“Feels like...you were made for me,” he mutters, pressing kisses to your jaw. “"oh, baby—baby, so tight—.”
Your fingers tangle in the collar of his shirt as you begin to move, slow at first—testing the angle, adjusting to the drag of him inside you. His cock fills you so perfectly that you can feel every ridge, every pulse, each motion scraping along all the right places. His arms wrap around you, anchoring you to him like he’s afraid to let you go.
You ride him with your arms around his shoulders, chest pressed to his, breath mingling as your pace builds. His hands stay on you—one guiding your hips in rhythm, the other slipping up to cradle the back of your head as he presses his mouth to yours again and again.
“You’re doing so good,” he breathes into your skin. “Just like that.”
Every time you sink back down, he meets you with an upward thrust, deeper and rougher now, chasing the pleasure that’s building between your thighs. You whine into his neck, clenching tighter around him with each pass, your skin damp and flushed.
“Matt— f- uck... nghh– ah! I’m gonna—” you gasp, voice high and shaking.
You fall apart in his lap, trembling around him as he fucks you through it, whispering praise against your skin until he follows—hips jerking up, cock buried deep, spilling inside you with a groan that echoes off the office walls.
You go still in his arms, both of you breathless, wrapped around each other like you’ve got nowhere else to be. The air is thick with heat, your skin tingling from the aftershock.
Eventually, you lean back just far enough to meet his eyes again—still dazed, your lips swollen, cheeks flushed.
“So…” you pant, lips quirking into a smile, “do I still get detention?”
Matt exhales a quiet laugh, brushing your hair back from your face, fingers curling loosely at the nape of your neck.
“You just earned straight A’s sweetheart.”
