An older man who obtained an app that can stop time infiltrates a women's rhythmic gymnastics team!! He plays a prank on the cute high school girl, Yuna Himekawa, who has changed into a leotard! When she performs her wide-legged technique using her soft body, it's the perfect opportunity!! He shifts the fabric of her leotard in the crotch area to expose her defenseless, bare vulva and inserts his penis deeply inside! Since time is stopped, he can do anything he wants. He sprays his essence all over the pristine vulva in the exclusively female domain that he could never have dared to enter before, thoroughly defiling it!!
