I've known my niece, Misono, since we were children. I was asked to take care of her while her parents were away from home. "I've always liked her." I thought we were close, but I never expected it to be the case...! When she took off her clothes, her huge breasts popped out, which didn't suit her baby face. Seeing her breasts, which were almost bursting out of her bra, I got so excited that I forgot about our relationship as uncle and niece...! "I want our first time together to be special." We had immoral raw sex without even a condom! I didn't know that it was a trap set by Misono, who was trying to create a fait accompli.
