Sandra runs the sex fight

The teacher and the teen were pitted against eachother, fucking until one of them surrendered after cumming too many times. All were too eager, fighters and audience alike.

Amber lunged at her quickly, but Miss H sidestepped and took hold of her arm. She brought her to the mat with an arm bar, Amber grunting and reaching for her hair. Sandra slapped her hand back, gripping her wrist and forcing it down. She mounted herself on Amber's back, grinding her hips into Amber's ass. The muscled nympho moaned loudly, starting to grind back into her.

"Your caveman strength won't help you now," Sandra purred viciously into her ear. "You like this? You like being the one being used like some well-crafted dildo, you little skank?"
Amber just moaned, even worse when Sandra rubbed her thigh between her legs enticingly.
