My niece, Misono, whom I've known since childhood. I decided to take care of her while her parents were away. "I've loved you for a long time." I thought we were very close, but I never expected this...! When she took off her clothes, her baby face and huge breasts were revealed. Faced with her breasts bursting out of her bra, she was so excited that she forgot about the relationship between uncle and niece...! "I hope my first time having sex will be special." Even the immoral act of not wearing a rubber band! Little did she know that this was a trap set by Misono to make things happen.
