This is really two movies bundled on one disk.

The first is the stepson fantasising about his very young and beautiful stepmother after peeping on her making love with his father or when she is masturbating. She sees him peeping and invites him to her bed. The only issue I have is that I did not understand how much was the son's fantasy and how much, if any, was reality.

The second movie is about the stepmother pulling her stepson out of work because she suspects he is having a gay relationship with a colleague. She then teaches him the sexual benefits of being straight by masturbating in front of him then introducing him to sex.

The only saving grace is getting to watch the delectable Chitose Hara's beauty for over four hours. However, even that would not make me watch this twice.
