While receiving erotic instruction inside the store, a beautiful girl suddenly appears, gently kissing me and touching my body. Yuka guides my hands to her breasts and pussy, letting me insert my fingers. She takes me to a room, gives me a blowjob, then tempts me with "Penetrate me from behind..." leading to standing doggystyle. Finally, she lies on her back and squeezes out every drop of my semen. Apologizing, I'm taken to a secluded spot where she dominantly makes me lick her entire body. She hands me a vibrator, inexperienced at first, but midway screams out "No, I can't take it anymore!" We enjoy hardcore sex in various positions, mostly with her on top.
