Justin and Emma, siblings bound by blood and forbidden desire, sneak into the bathroom, their hearts pounding in sync. They stand before the mirror, Justin's reflection showing his throbbing cock, Emma's revealing her glistening pussy. They cannot resist, their hands reaching out, touching, exploring. Justin's fingers trace Emma's slit, her wetness coating his digits as she whimpers. Emma wraps her hand around Justin's shaft, stroking him firmly, feeling him grow impossibly harder. Their eyes locked in the mirror, they give in to their taboo temptation, their bodies craving the release only they can provide.
