BLK-352 One day, I suddenly switched bodies with my sister's boyfriend and had sex with him all day long.

What on earth is going on?! My body has been swapped with my sister's boyfriend's?! My sister, who was looking at me with scorn and disdain until just now, is now inviting me with kitten-like eyes! This is the start of a crazy day! 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 you were cumming inside her so much, or that her nipples were pink.
