You go to school with his cum in your panties

You sit in the passenger seat of the car, the engine already running, the heater blowing warm air against your nylon-clad legs. The seatbelt presses across your chest, and every small movement makes the cooling mess in your panties shift and cling. Your thighs are still damp, the fabric of your tights stuck to your skin in places. You can smell yourself—salty, sharp, mixed with his scent—and it makes your face burn even as a low, unwanted throb pulses between your legs.

Your stepfather reverses out of the space without looking at you. For a minute the only sounds are the indicator clicking and the low rumble of the engine. Then he speaks, voice low and matter-of-fact.

“You’re going to walk into that school with my cum soaking through those little panties all morning. Every time you sit down in class, every time you cross your legs, you’re going to feel it. And you’re going to smile and say yes sir to your teachers while you do it.”

You swallow. Your fingers tighten on the strap of your school bag. The blazer feels too tight across your shoulders; the short skirt has ridden up slightly on the seat. You try to tug it down and your knuckles brush the wet patch. A small, involuntary sound escapes you.

He glances over, mouth twitching. “That’s better. You were so quiet just now but you licked your fingers clean without me even telling you to. Didn’t you?”

“Yes,” you whisper. The word feels thick in your mouth.

“Yes what?”

Your stomach flips. “Yes, Daddy.”

He nods, satisfied, and turns onto the main road. Traffic is light this early. Streetlights still glow against the grey morning. You watch your own reflection in the side window—blonde plaits, neat blazer, the collar of your school shirt buttoned high—and try to reconcile it with the sticky heat still trapped against your skin.

“When we get there,” he continues, “you’ll get out like a normal girl. You’ll wave. You’ll say thank you for the lift. And then you’ll walk through those gates knowing I’ve already used you once today and I’m going to use you again later. Your mother thinks you’re staying late for revision. I’ve told her I’ll pick you up after. You’ll wait for me by the side gate. Don’t talk to anyone. Don’t change your underwear. I want to see what’s left of it when I get you in the car.”

The car slows as you approach the school. Other students are already on the pavement, bags slung over shoulders, laughing. A group of girls in the same navy uniform glance over as he pulls up. One of them recognises the car and lifts a hand. You force a small smile and wave back, feeling the wet fabric shift as you lean forward to unclip your seatbelt.

He catches your wrist before you can open the door. His thumb presses against the pulse point.

“One more thing. If anyone asks why you’re walking funny, you tell them you pulled a muscle in PE yesterday. Understand?”

You nod. Your knees feel unsteady again.

“Good girl.” He lets go. “Now get out. And Michelle—”

You pause, one foot on the pavement, the cool morning air hitting the damp heat between your legs.

“Don’t forget who you belong to now.”

The door shuts behind you. You stand on the kerb in your school shoes, blazer buttoned, bag hanging from one shoulder, and watch the car pull away. The wetness is already starting to cool against your skin. You take a careful step toward the gates, thighs brushing, and feel a fresh trickle seep into the crotch of your tights. Somewhere behind you a car horn beeps. You keep walking, shoulders straight, face carefully blank, already counting the hours until the side gate.

You push through the main gates with the rest of the early arrivals. The navy skirt swishes against your thighs with every step, and each brush of fabric makes the sticky patch in your panties shift and cool. You keep your bag low against your hip, shoulders squared, eyes fixed on the path ahead. A couple of girls from your form call your name. You lift a hand and manage a small smile, but you don’t slow down. Your gait feels wrong—slightly stiff, thighs not quite wanting to part the way they should. You tell yourself it’s just the cold.

Inside the building the heating hits you. The smell of your own arousal and his cum seems stronger in the warmer air. You head straight for the girls’ toilets on the ground floor, lock yourself in the end cubicle, and lean against the door. For a moment you just breathe. Then you hitch the skirt up, hook your thumbs under the waistband of the tights and the little lace panties, and ease them down to mid-thigh.

The mess is worse than you expected. Thick streaks have soaked into the gusset and smeared across the front of the panties; some has already dried in pale flakes on your skin. When you touch yourself the wetness is still slick in places, cold in others. Your fingers come away sticky. A fresh pulse of heat runs through you even as your stomach turns. You wipe carefully with toilet paper, then again, until most of the visible mess is gone, but you can still feel the dampness when you pull the panties and tights back up. The fabric clings. You wash your hands twice at the sink, avoid your own eyes in the mirror, and re-do the top button of your shirt.

Registration is in ten minutes. You walk into the form room and take your usual seat near the window. The chair is hard plastic. The moment you sit, the pressure of the wet gusset against you makes your breath catch. You cross your legs, then uncross them when that only makes it worse, and settle for sitting very still. Your form tutor is already calling names. When she reaches Michelle you answer “Here” in a voice that sounds almost normal. The girl next to you leans over and whispers something about the weekend. You nod and smile, and under the desk your fingers press once, hard, against the front of your skirt, right over the damp heat, before you force them back onto your bag.

The bell goes. First period is maths. You walk the corridor with the others, feeling the slow, steady seep every time your thighs brush. By the time you sit down in the classroom the panties are wet again, and every time you shift in your seat the cool stickiness reminds you exactly whose cum is still inside them. You open your exercise book, write the date at the top of the page, and try to focus on the board. The numbers blur. Under the desk your knees press together. You can already feel the next trickle starting.
