Angle grinding & prone position masturbation, secretly and uncontrollably raising legs masturbation FGAN-165

Unlike the exaggerated orgasms and M-shaped leg spreads often seen in adult videos, this is real masturbation! It features fetish masturbation themed around angle grinding and prone masturbation, primarily the earliest forms of masturbation for girls. It also includes leg-raising masturbation, a form of masturbation that feels immoral and can't be resisted, done secretly because of a small trigger.
