A slutty, overweight woman with hundreds of men under her belt was brought to orgasm by a virgin's huge penis; a hot, slutty woman, Nonomiya Amami, DVAJ-623.

A blonde, J-series girl named Yu loves sex and is an experienced, promiscuous woman (she's furious about being called a promiscuous woman...). One day, having lost a bet with her friends, Yu is forced to accept the punishment of "giving oral sex to a virgin and taking a selfie," and the one performing this task is her childhood friend. She used to think sleeping with a virgin was no problem... but unexpectedly, he has the biggest penis she's ever had! Yu experiences an unknown pleasure as the enormous penis scrapes against the depths of her uterus. Whether in a riding position or doggy style, she is completely lost in the experience of having sex with the virgin's penis, having long forgotten that this is just a punishment game.
