In high school, Yoichi had it all. He was the coolest guy in school, with a loving girlfriend and a cute childhood friend that would do anything for him, so when they told him they were going to live in a share house in Tokyo for college, he wasn't worried in the least. Little did he know that the random guy that's their new housemate has a hypnotizing way with women... and a huge dick!

Back at the share house again, Yoichi's girlfriend Nao still can't stop lusting after her housemate's dick. When Yoichi comes to visit for summer break, she finally realizes she won't ever be satisfied by him and decides to give up her dignity, her pride, and her body all in the name of pleasure... all while Yoichi is asleep in the same room!
