I never imagined that my mother's best friend would have such a voluptuous, curvy body... The son can't take his eyes off Mika's I-cup breasts. He wants to find a way to get closer to her, but he rarely has the chance to talk to women and lacks the courage. If things continue like this, nothing will happen. In his desperation, the son uses Mika's underwear for masturbation while she is in the bath, but at the worst possible timing, Mika comes out of the bathroom...
