In the dimly lit gym, Megan and August, clad in tight workout gear, await Maya Farrell, their bisexual trainer. As Maya arrives, her eyes linger on the wives' bodies, sparking an unspoken agreement. The workout begins, but it's not long before hands wander, caressing muscles that aren't being exercised. Maya's strong hands grip August's ass, making her gasp. Megan, watching, can't help but touch herself. Maya smiles, pulling out a harnessed dildo, and the real workout begins. The wives take turns riding Maya, their moans echoing in the empty gym, as they fulfill their cuckold fantasy, craving more of their trainer's dominance.
