Like your typical stepsiblings, Holly and Rion are constantly bickering. They try to call dibs on everything, but it means that they’re always on guard and making deals with each other. They devise a new set of rules where calling dibs is sacred and undeniable. The first thing Rion calls dibs on is Holly’s ass and her mouth. With that being the case, Holly calls dibs on Rion’s cock. The stepsiblings fuck each other to their heart's content and use each other as they please.
