A man who has obtained an app that can stop time infiltrates the girls' rhythmic gymnastics club! He plays pranks on the cute high school girl, Yuna Himekawa, who has changed into a leotard! His chance is when she uses her flexible body to perform a wide-open leg technique! He pushes the fabric of the leotard aside and thrusts his dick deep into her defenseless, exposed pussy! Time has stopped, so he can do whatever he wants. In the women's territory that he could never enter before, he spreads his old man juice all over her, soiling her lovely pussy!
