Peek through the therapist’s door — skinny stepsister on the couch, pretending to zone out while stepbro kneels between her thighs. Blouse unbuttoned, tits half-out of bra. He shoves two fingers inside first, then lines up that thick cock. Rides him like a cowgirl with her back arched, moaning into the pillow as he buries himself deeper. She knew someone was watching from behind the blinds when she let him take control. Ass lifted high off the couch for that deep penetration—cock hitting all the right spots until she’s screaming his name. Cumshot so messy it drips down her inner thighs before he flips her onto all fours for one last brutal thrust.
