Kimberly’s sister was visiting from the other side of the state for the week, so she knew that she’d be on ass and balls duty while her sister got to suck her boyfriend’s cock and get fucked in the ass.

It was only fair, after all, Kimberly got to have her ass, cunt, and mouth used by her boyfriend all year, but her older sister only had a chance to service his cock a few times each year. She couldn’t be greedy and it was the polite thing to do, allowing her sister primary slut status on her visits.

And after all, when Kimberly visited her sister in the Spring, her sister’s husband would be fucking her tight ass the entire time.
