IESP-681 - 碓氷れん レズ解禁 妹に恋した私

One of the better ones in this series. It felt like watching a couple of close friends.

It starts with them undressing in the changing room before their bath. They soak in the tub and share a lesbian kiss. The post-bath kissing scene is quite long. I kept wondering when I'd finally see them fully undressed or naked. Ren starts by aggressively seducing Yu. Ren is wearing salmon-pink panties, and just when I was wondering what color Yu's underwear was, it turns out she's commando—what a shock. It ends with a beautiful lesbian sex scene.

This is why the 'Lesbian Unlocked' series is so dangerous. The 69 scene in the middle is practically a work of art at this point.

The height difference and the sister dynamic worked well. It was a classic setup where the younger sister goes after the reluctant older one. I was disappointed that the anal wasn't visible and the 69 scene was lackluster. I don't think this is for impatient viewers. Both of them looked great, though.

There are more intense scenes in other entries of this series, but considering the chemistry and the emotional intimacy between the two, this is the masterpiece. Above all, they are both gorgeous. Just stunning. I really savored that sticky, lesbian-specific atmosphere. I can't believe this was Ren Usui's lesbian debut. If she's still active, I hope she keeps doing these. She's more erotic than most veteran actresses.
