Nick's heart races as he hides, listening to Kathia's provocative whispers into the phone. His cock tents his pants as he watches her strip, her natural tits and big ass on full display. She sits on the bed, legs spread, fingers teasing her pussy. Nick's hand moves to his cock, stroking it in rhythm with Kathia's self-pleasure. Her moans fill the room, spurring Nick on. As she climaxes, her body convulsing, Nick can't hold back. He stands, his cock in his hand, and unleashes a torrent of cum, his body shaking with the force of his release. Panting, he watches Kathia, now sated, end her call, entirely unaware of her stepson's voyeuristic pleasure.
