Erotic torture using a timer-controlled vibrator. Riko is a sensitive girl who gets paralyzed by the intense vibrations. With a penis attachment and her hands bound, she’s subjected to an hour of non-stop, random stimulation.











There's no unnecessary interference (direction, camera work, editing), so it feels raw and genuinely erotic. It makes you realize that it can be this sexy even without the act itself... In fact, because there's no sex, I found myself getting excited over things I usually ignore in AVs, like the way she brushes her hair, the skin spilling out from her underwear, or the gloss on her lips. Combined with Riko Sato's natural, simple charm, it feels like we're playing naughty games together. She's not a classic beauty, but just like how someone looks prettier when you fall in love with them, by the second half, I was already hooked. Recommended for those who are bored with standard, formulaic AV production.
Maybe she's trying too hard to hold back the pleasure from the vibrator, but she just keeps breathing rhythmically like she's in labor. When I think of Sato Riko, I think of 'ahegao,' but this was just a weird face, probably because she was holding back. I was hoping for more intense, full-blown climaxing, so it was a letdown.
