After his father remarried, Banji finds himself living with his young stepmother, Rin. Having been raised under strict academic pressure, Banji knows nothing about sex and is still suffering from nightly emissions. Feeling responsible as a mother, Rin decides to take matters into her own hands: 'I'll teach you how to handle yourself properly. Keep this a secret from your father, and no touching me!'








This work is excellent! The actress's earnestness is cute, her looks are alluring, and above all, she's overflowing with maternal instincts, which adds a great flavor. Watching this changed my preferences a bit—I realized that curvy, voluptuous women are also great. There are many stories about affairs with stepmothers, but I've never seen one that depicts the characters' inner lives and the mother-son dynamic so carefully. It's so well-made it could almost be used as a sex education manual. Also, for an AV, the BGM is used effectively throughout to build the atmosphere, and the song choices are quite good. The story structure also has detailed direction at every turn, making it high-quality as a drama as well. That strange look the stepmother gives her son in the final scene really fuels the imagination. I'm looking forward to Part 2 to see what happens next. There's a slight sense of awkwardness due to the age gap with the actor playing the high schooler, but for me, this is definitely a permanent keeper. P.S. It's hilarious when the actor (the son) occasionally breaks character while getting a handjob!
I've bought many of Rin-chan's works, but I've never seen her play a stepmother who provides 'sex education' like this before. It seems the experience she gained after transitioning to AV wasn't in vain. Her sexual sensitivity is high, of course, but her technique has also improved significantly. For example, using her mouth to put a condom directly onto the penis is a common technique used by 'sex workers.' It really shows she's been trained by working both in AV and high-end delivery health services. There are only two actual sex scenes, which is a bit low. Perhaps it couldn't be helped since the plot involves teaching sex through thigh-fucking as part of the 'education.' Still, a development where he forces penetration might have been good too. Regardless, if you had a stepmother with such massive breasts living under the same roof during your student days, you'd definitely do her without a second thought. Rin-chan's polite-speech sex education was stimulating enough to make you think just that.
