BRK-011 - Training my best friend's mom, Kyoko

Junichi is still treated like a servant by his childhood friend Naoya, even in college. But he has a secret motive for hanging around: Naoya's mom, Kyoko. When Junichi finds himself alone with the sexually frustrated Kyoko, he can't resist taking advantage of the moment. With the help of an aphrodisiac, the once-composed Kyoko slowly turns into Junichi's submissive toy, crossing lines she never thought she would.
