[Reducing Mosaic]HBAD-701 My friend's little sister had big tits and seemed docile, so I secretly lured her out and fucked her senseless. Turns out she was a woman who could cum endlessly. Kaito Kitamura.

Kenji and his coworkers often drink at Hiroshi's house after work. One day, drunk Kenji peeks at Hiroshi's sister, the plain Kaichi, while she's taking a bath and sees that she has huge breasts and an erotic body, making him lustful and wanting to have sex with her. Kenji takes advantage of Hiroshi's absence to pressure Kaichi, who complies with everything without any resistance. Thus, Kenji had sex with the super-sensitive and erotic Kaichi as much as he wanted.
