Yuko, a married personal trainer, invites her friend and her friend's daughter, Aya, over for home workouts while her husband is away on a long business trip. Little does she know, the much younger Aya has been eyeing her body all along. Soon, Yuko finds herself completely overwhelmed and seduced by Aya's expert lesbian techniques.










美熟女の森下美緒・・・跡美しゅりと一緒に見ちゃうとやっぱ年の差を感じちゃいますね!そう言う意味では、この作品のタイトルが成り立っているのかも・・・ 跡美しゅりの押せ押せの攻めはいいとして、森下美緒が敏感すぎて、駆け引きの部分は薄目・・・もうちょい粘って欲しかった。
Watching the beautiful mature woman, Mio Morishita, get toyed with by the lesbian techniques of Shuri Atomi—who could easily pass for a beautiful young girl—was, in my opinion, top-tier. It’s exactly as the title suggests; the way the mature woman can't even resist and just writhes under the younger girl's caresses is incredibly arousing. If the roles were reversed, it wouldn't work like this, and mutual caressing feels unnatural; being on the receiving end of one-sided affection feels much more authentic. Since the setting is a home training session, the outfits aren't super sexy, but I actually liked that. Also, with the slender Shuri as her partner, Mio's curvy, fleshy body stood out even more, making it look extra erotic.
I love this series and own every title. Embarrassingly, I discovered Director Koyama through this series and have been a fan of his work ever since. However, this one was a letdown. Since 2 and 3 were so good, this felt lacking. The runtime was shorter, too. I believe Director Koyama is the best at 'shell-matching' (cunnilingus) scenes. I look forward to your future work. That said, the chemistry with the actress was poor. The older actress lacked intensity; I always thought the highlight of this series was the climax, but she just let the younger actress lead the whole time. Director Koyama, I have high expectations for your future projects, including casting choices.
