Hibiki Otsuki, who claims that her nipples are her erogenous zones, is tested to see if she can cum just from her nipples! Every time her nipples are played with, Hibiki's body twitches and arches as she cums. However, when the stimulation continues, she screams so loudly that the staff is amazed, and she cums just from her nipples. Hibiki's nipples become so sensitive that she can't stop cumming and she has multiple orgasms!! It's really erotic to see a woman cum just from her nipples.
