Of course her boyfriend had to fuck her older sister up the ass when they went to visit over the holiday, it was only proper manners. However, they quickly ran out of lube, so she spent the week wetting his cock with her mouth every few strokes he slammed it up her big sister’s asshole. The taste of her older sister’s ass was a bit much at first, but she quickly got used to it. She already had plans for dumping out the lube the next time they came to visit her.
