What on earth is going on!? My body has been swapped with my sister's boyfriend!? My sister, who looked at me like I was trash and looked down on me, is now inviting me with kitten-like eyes! An incredible day is about to begin! The day has finally come when I can have sex with my cute sister, who has a bad attitude! Little sister...I didn't know you were doing such perverted things on a daily basis. Big brother, I had no idea that you were cumming inside her so much, or that her nipples were pink.
