She has her way with you

Before you can answer she shifts her weight, grinding her thick, muscular thighs against your hips. The singlet does nothing to hide the heavy press of her massive tits as she leans down, trapping your arms under her bulk. You try to buck her off, but it's like trying to move a parked truck. Osla just chuckles, low and amused, and rolls her hips deliberately, rubbing the crotch of her singlet against the growing bulge in yours.

"Coach said practice," she murmurs, voice thick with amusement. "So I'm practicing keeping you down."

She reaches down between your bodies, thick fingers wrapping around the outline of your cock through the thin fabric and giving it a firm squeeze. You grunt. She squeezes harder, then starts stroking you through the singlet while she keeps you pinned, her other hand planted on your chest like an anchor. Every time you try to twist free she just presses more of her weight onto you, crushing you into the mat until the air leaves your lungs in short, helpless bursts.

Osla leans in close, breath hot against your ear. "You're hard already. Cute."

Eventually she lets you up, only long enough for the next "match." The second you stand she clinches, locks her arms under yours, and lifts. Your feet leave the mat. A second later the world flips as she suplexes you flat onto your back hard enough to knock the wind out of you. She lands on top again, this time straddling your chest, massive thighs pinning your arms while she grinds her singlet-covered cunt right against your face.

"Pin," she announces, grinding harder. "Stay down, bitch."

She stays there a few extra seconds, rolling her hips so you can feel the heat and dampness of her through the fabric, then hauls you up by the singlet straps like a ragdoll and throws you into the next hold. A rear choke this time. One thick arm snakes around your throat from behind while her other hand locks it in place. She drops to the mat with you trapped against her, legs wrapping around your waist in a body scissors that squeezes the air out of your lungs. You can feel her big tits pressed against your back as she flexes, cutting off your air until black spots dance at the edges of your vision.

When she finally loosens the choke she shoves you face-down, mounts your back, and starts humping against your ass in slow, heavy thrusts, still talking shit the whole time.

"Look at you. Can't even stay on your feet. Just a soft little toy for me to break."

She stands, drags you up by the hair, and the cycle repeats. Another takedown. Another pin. Another round of her using you however she wants. Sometimes she sits on your face while she strokes your cock through the singlet. Sometimes she flips you onto your stomach, yanks the crotch aside, and grinds her thick thighs around your shaft while she pins your wrists above your head. Sometimes she just lies on top of you in full mount, crushing you under her bulk while she dry-humps until the mat is damp beneath you both.

Every single time she takes the top position. Every single time she decides when you get air, when you get friction, when you get to move at all. Verbal abuse pours out of her between pins.

"Pathetic."

"You're not even trying."

"This is what you signed up for, right? Getting dominated by a real athlete?"

"Keep moaning like that and I'll make you cum right here in front of everyone."

By the time the coach's whistle finally cuts across the gym your body is a map of mat burns and her fingerprints. Osla is still on top of you from the last pin, one heavy thigh locked across your hips, her hand still slowly stroking your cock that she pulled free several matches ago. She gives it one last firm squeeze, then tucks it back into the singlet like she's putting away equipment, as she sits on your face and lazily pulls you into one last body lock.

The coach calls everyone to the changing rooms. Osla still on your, pushes her ass into your face and gives you one last hard squeez to make your body creak, before finally letting you go.

She stands up in one smooth motion, offers a hand, and hauls you to your feet as if you weigh nothing.

"Good practice," she says, smiling, still completely in control. "Now be good and get your clothes and come to girls changing room, straight to my stall, I'll have my shower stall open." And leaves for the girls changing room. Not bothering to look back
