My childhood friend is always defenseless and unguarded in front of me. One day, I looked next to her and saw that she was not wearing a bra and her nipples were erect! I touched her Kokoro and she seemed embarrassed, so I started to play around with her and twisted her nipples, and she had a series of explosive orgasms! My childhood friend, who I had been treating as a male friend, has become a slutty woman who asks for penetration while teasing her nipples! And I suddenly felt like a woman and my heart was beating fast... Our relationship changed drastically from that day on.
