In the dimly lit, private gym, the trio begins, Kira and Nadia in matching workout gear, Peter in loose shorts. As they stretch, Peter's eyes linger on their tight bodies. Kira winks, knowing the real workout is about to start. Nadia, eager and innocent, doesn't protest as Peter pulls her into a kiss, his hands roaming her teen curves. Kira joins in, sucking Peter's cock as he fucks Nadia from behind. They move to a threesome, Kira riding Peter while Nadia licks her stepmom's clit. Throughout the workout, they're freeuse, Peter fucking them anytime, anywhere, until they're spent, their bodies marked with sweat and cum.
