I invited Ria, a plain, slender beauty with abnormally lewd breasts, over to my house again today. She looks pure, but her sexual tendencies are that of a lewd, extremely masochistic girl. She seems to like me, but she has no interest in going out with me. But she's an excellent sex friend! In my bed at home, in the bath, at the entrance, whenever I got horny, I instinctively let out my sexual desires, and this is a record of our completely self-satisfied sex.
