Logan Pierce is engaged in a game of "I'll show you mine if you show me yours" with Aria Alexander when Aria's stepsister Jessa Rhodes walks in on their fun. The blonde is immediately upset, saying that she thought she was Logan's favorite. Piqued, she pulls off Aria's panties and then forces Logan to choose which vagina he likes better.

Unable to pick without trying out both pussies, Logan sets to work making his decision. He starts out with finger fucking both girls in tandem, but soon the competition escalates into the two girls seeing which one can give the best blowjob.

Before Logan knows it he has managed to instigate a full-on threesome with the two stepsisters. The girls take turns letting him fuck their horny little pussies and eating each other out as they work out their sibling rivalry in the sexiest possible way. Soon Aria and Jessa have coaxed Logan into a climax of his own all over their lusty faces. As they bask in the afterglow, Logan finds that he still must decide whose pussy is best.
