ADN-795 I started to see my tomboyish friend with huge hidden boobs as the opposite sex. Tsubaki Miyahara.

Tsubaki is part of the group that always hangs out together. I had never thought of her as a member of the opposite sex, but after she was confessed to by my friend, my perception of her changed a bit. 'Should I go out with him?' she asked me for advice, and even though I didn't want to, I acted like it was no big deal. Around the time I started realizing my own feelings, Tsubaki invited me. "I decided to go out with him, so let's have sex one last time."
