ROYD-007 Suddenly confide in you about troubles. My sister's friend has a big breast complex, named Hagizuki Rino.

My sister's friend who often comes to our house has a complex about her huge breasts and is a shy, cute girl. When she came for an overnight stay, I got lucky and saw her in a swimsuit while we were taking a bath together, and was shocked by her massive breasts! Furthermore, the expression on her face as she tried to hide her breasts was so adorable that even though I knew it was wrong, I decided to sneak into her room at night. I couldn't hold back and ended up ejaculating inside her, but instead of getting angry, she said if I was excited by her huge breasts then she would confide in me and show them to me herself…
