A high school student like me suddenly got a 23-year-old stepmother. Even though she's my father's new wife, living with a beautiful woman with such big boobs... I can't help but use her as wanking material! Sensing my boiling sexual desire, my stepmother secretly stimulates my erect cock and relieves my sexual needs without my father knowing. Ahh... it's like a dream... but I can't be satisfied with just her mouth and boobs anymore! Please, teach me how to have sex! Recorded in digital mosaic.
