This series focuses on "leg-straight orgasms," a natural, instinctive bodily sign of ecstasy rather than a staged performance.

In this installment, Hibiki Uta, who claims to have been secretly masturbating in the corner of her legs since she was little, shows off her leg-straight orgasms multiple times.

The two sex scenes include V-shaped leg spreads and orgasms where her soles are wide open! If you straighten your legs while watching this, you're sure to experience a synchronized orgasm!
