Yuna Matsuoka - "I Masturbate every day..." Prim and proper girl has first ever mind-blowing sex

We were surprised to hear that she masturbates every day. It seems that when she was a young, she was immersed in a lot of study, and this may have been a reaction to that. When I showed her my cock, she reacted in a puzzled way, but when I put it in, she looked really happy. The occasional confused look on her face was very cute.
