Zuzana Z, the gym's youngest and most flexible member, invites her new friend for a late-night 'training session'. They start with some basic stretches, but Zuzana has other moves in mind. She pulls out a shiny dildo, running it along her friend's inner thigh, making her shiver. They kiss, their tongues dancing as Zuzana's fingers find their way into her friend's tight pussy. She slips the toy in, moving it in and out slowly, her friend's moans driving her on. They switch places, Zuzana's eyes locked on the toy disappearing into her friend's eager cunt.
