Vlasa and Semera's experiment in open relationship takes an unexpected turn when their neighbor Stepan joins in. Semera, on all fours, takes Stepan's thick cock in doggystyle while Vlasa watches, stroking her own pussy. Vlasa can't resist, moving in to lick Semera's clit as she's fucked, making Semera moan loudly. Stepan, loving the view, fucks Semera harder, his balls slapping against her wet pussy. Vlasa, turned on, pulls out a strapon and joins the fun, fucking Semera's mouth while Stepan pounds her pussy. Semera orgasms, her body shaking, and Vlasa cum's in her mouth twice.
