The visitor is a slender girl from the swimming club! When she's made to change into her usual competitive swimming swimsuit, it's sexual harassment treatment! A mask soaked in a liquid that makes you lose consciousness is put on her, increasing her sensitivity! Her sensitive small breasts are stimulated, and her whole body twitches! She can't stop cumming and is in a state of obedience! Unable to refuse insertion, she goes crazy for nipple kneading sex!!
