For the swimming class that starts in summer, a swimwear fitting event is going to be held at school. Hinano can't afford a new swimsuit, so she wants to get through this summer with her old one… In the midst of all this, a perverted PE teacher says 'Let me teach you some tricks' and rubs her nipples over her swimsuit, forcefully developing them! The nipples of a growing body are too sensitive, arching the body to reach climax! As the mischief escalates, the small body convulses and leaks urine! The PE teacher calls in more friends to torment the nipples! Shooting thick semen onto the tight swimsuit… A defenseless Ruri girl becomes an outlet for the desires of perverted adults. ※There are no performers under the age of 18 in this work.
