In a dimly lit gym, Sheila, a tall, muscular woman with fierce eyes and a hard chest, works out aggressively. Suddenly, she notices a strange craving for protein. She walks to the water fountain, undoes her sports bra, and begins to suck on her own large nipples. Much to her surprise, someone else joins her.
It's Jenna, a lean, younger woman who has been secretly watching Sheila. They lock eyes, and without saying a word, Jenna bends over the water fountain. Sheila approaches her, slapping her meaty ass cheeks. Jenna moans as Sheila lowers her head, taking Jenna's erect nipple between her sharp teeth.
They move to the mats, their movements frantic and primal. Sheila rips Jenna's sports bra off as they wrestle each other to the ground, their sweat-slicked bodies grinding together in a fierce display of passionate aggression.
