Misako (the hot young neighbor next door) has asked Tetsuya to come over to her place and help her with her cleaning. Even though their relationship is like older sister and younger brother, he definitely feels very attracted towards Misako. Due to a mishap from Tetsuya she finds out that he has an erection. He though she will scold him, but instead of that she tells him that holding back is bad and if he wants she will help him masturbating.
You know how this one will end, right 😉
