Satoshi falls in love with his friend's mother, Maki. He doesn't know what to do with his feelings, so he picks up her underwear in desperation. However, when Maki sees it, he begins to distance himself from her embarrassment. She teaches the innocent Satoshi, who doesn't even know how to masturbate, how to vent her, but he loses herself in her first pleasure and is pushed down. Maki's body can't resist the wave of pleasure to Satoshi's cock that pistons violently like a monkey many times.
