BLK-352 One day, I suddenly switched places with my sister's boyfriend and fucked all day long. Kanasato Miri.

What the hell is going on!? My sister's boyfriend and my body have been swapped!? Just a moment ago, she was looking at me with eyes that said I was trash, despising me, but now my sister is looking at me with kitten-like eyes, trying to seduce me! This is going to be one crazy day! Even though her attitude is bad, my incredibly cute little sister, the day has finally come where I can fuck her! Sister... you've been doing such perverted things all along. I had no idea you were getting creampied or that your nipples are pink.
