EKDV-592 My parents are absent on a trip ... When I was alone, my cute sister changed suddenly! ?? I became super aggressive and came to steal my body! !! Mitsuki Nagisa

The remarried parent's stepchild [Mitsuki] is a serious and cute sister-in-law who is popular with everyone. I was happy to have such a younger sister. One day, my parents set out on a day trip from the morning. I decided to spend the day with [Mitsuki] alone. I lived my usual life, but when I was alone in the living room, my cute addiction changed. I kissed with saliva, showed off my masturbation, came to wash my body in the bath, became super aggressive and came to rob me of my body. What should I do!
