One day, Yumi consults her sister Rin about wanting to have sex with her own son. Initially shocked, Rin reveals she shares the same taboo desire. They decide to swap sons to satisfy their urges. The seductive, heavy-breasted mothers begin their lewd games...




















This is an extremely perverted work featuring a biological son instead of a stepmother, and even depicts a nephew-swapping scenario where sisters exchange sons. As someone who only watches for Rin Aoki, I usually don't care for anything other than her solo works, but the synergy with Yumi Kazama here creates an eroticism you just can't get in a solo film. Among her many co-stars, Yumi Kazama is definitely the best. Notably, you get to see a stylish Rin-rin without her usual hair and makeup or nails, and the dialogueโfilled with slang alongside her moansโdoubles the eroticism. I've seen her masturbation scenes in many films, but here she even performs finger penetration, which she rarely does elsewhere. Perhaps because it was filmed at a resort, the outdoor scenes have a sense of liberation that creates a different kind of erotic atmosphere compared to indoor shoots. As an aside, I laughed when a dog suddenly appeared out of nowhere to sniff around after she finished him off with a handjob. It's surprisingly humorous, too.
It felt like watching two different AVs playing at the same time; there was zero chemistry between Kazama and Aoki. Even if lesbian play was off the table, they could have at least fondled each other's breasts. I also wanted more variety, like having two male actors go after one actress at the same time.
I rented this because I like both of them, but there's too much oral and only one actual intercourse scene at the end. Even the finish is just simulated, so it's a shame there's no cleanup.
For a cheap 1480 yen title, the balance between the two was pretty good. Yumi Kazama was the focus, but Rin also gave a solid performance throughout the 95 minutes. You can tell they saved on production costs by filming out in nature.
