My little sister, who always tries to get close to me with a lot of skinship. She's cute, but I definitely can't feel lust for my sister. Moreover, I'm a virgin. Because I want to lose this virginity with my girlfriend someday, my sister is honestly not on my radar. But my sister wasn't like that! When I wake up in the middle of the night feeling a strange sensation in my lower body, my sister is inserting my dick!? I try to stop her in a panic, but it's too late. Having lost my virginity unexpectedly, I decided to have a serious sex session with my sister!
