That's not your girlfriend's sister you're fucking, buddy.

Lynna Nilsson, who's 40 years old and married, knew her daughter's boyfriend was coming over, but since her daughter wasn't home, she decided to put on her daughter's collegebabe uniform, and you'd best believe it looks better on this gorgeous blonde. She answers the door, and the guy assumes Lynna is his babefriend's sister. Wrong, but Lynna isn't going to correct him.
