Takeshi, who came to Tokyo for the university entrance exam, decided to stay at his older brother's house in Tokyo and take the entrance exam. My brother's wife Maria, whom I met for the first time in a while, is a gym instructor and is attractive with her toned body and G-cup breasts. Takeshi becomes lustful for his sister-in-law and thinks that he can somehow have sex with her, so he buys an aphrodisiac on the internet and puts it in his protein shake. Maria, who was exercising in the living room, drinks the aphrodisiac protein while exercising. Maria's body gradually begins to heat up due to the aphrodisiac effect, and she instinctively touches her crotch and masturbates. She was attacked by Takeshi who was watching the situation, but she ended up asking for his cock herself. Gangimari NTR, Maria Chihaya's creampie ban lifted!
