Nanami, whose husband is on a business trip and who has been sexless, takes care of her nephew from her sister. The nephew is an extreme studious type and starts studying as soon as he arrives at Nanami's house, ignoring her completely. This attitude stirs the blood of Nanami's former promiscuous self, leading her to seduce him. Initially ignored, she succeeds in making him erect (with a huge penis)! Then, late at night, she initiates reverse night● and takes his virginity, but his sexual desire explodes after their first sex! Not satisfied with just one time, he forcefully has unprotected sex even when condoms run out. Furthermore, as Nanami tries to escape, he holds her down while keeping his penis inserted and ejaculates inside her multiple times!
