It seems that a swimsuit fitting will be held at school for the pool lessons that start in summer. Hinano-chan wants to get through this summer with a small swimsuit because she can't buy a new one... In the midst of this, a perverted gym teacher says "I'll teach you a secret technique" and has her nipples played with over her swimsuit, developing forced cum! Her plump nipples, which are still developing, are too sensitive and cause her body to arch backwards and climax! While twitching her small body with escalating pranks, she has a squirting climax! The gym teacher calls in more friends and torments her nipples! Pouring thick semen onto her tight swimsuit... The defenseless girl becomes an outlet for the desires of the perverted adults. *There are no performers under the age of 18 in this work.
