"My first masturbation was rubbing..." These perverted girls learned to masturbate from a young age and soothed their bodies by rubbing their crotches against the futon... We asked these girls to show us the origins of pleasure! The girls were confused at first, but gradually they remembered the climax points and became absorbed! They masturbated in earnest, twisting their hips as their instincts dictated... This is a work that is sure to excite you, if you love masturbation!
