Nanaho is my friend's sister, whom I've known since childhood. Now that she's grown up in Kokoro and body, she's become curious about sex. When I heard that she recently got a boyfriend and is enjoying blowjobs and sex, I finally started to think of her as an adult woman. I offered my stiff penis in front of my friend's sister, made her take it in her mouth, and she swallowed my semen. Unable to hold back, they both end up experiencing forbidden sex. Watch the dangerous and obscene daily life of my brother and his childhood friends.
