The sexy Lilly Hall lives with her annoying prankster boyfriend JMac. JMac's newest way of having fun is to sneak up behind Lilly around the house and pants her, showing off her gorgeous ass. They make a wager: if JMac can pants Lilly three times in a week, she has to let him fuck her ass. Prank master JMac has no problem succeeding, pantsing Lilly for a final time as she does yoga. Lilly, annoyed but horny, is true to her word and lets JMac pound her ass with his big cock.
