My Husband's Other Son is Like No Other... Nanako Yoshioka

Stepmother Nanako is troubled by her relationship with her husband's son, Masashi. Worried that he won't come out of his room while studying for exams, she checks on him... and finds him sleeping with his erect cock exposed. Nanako, feeling a throbbing in her crotch at Masashi's impressive rod, can't resist and starts a handjob... She then guides him to ejaculation when he wakes up and begs her. But Masashi, unsatisfied with just one shot, presses her while showing off his erect cock, and Nanako, like a spark to dry tinder, can't refuse...
