Dibs! A pretty common way amongst step-siblings to call front seats, best views or even prime beds or bedrooms. Haley is just too fast for her step-brother Jimmy on their family vacation and calls dibs on the nice bed - leaving Jimmy a nasty old couch or lousy bunk to rest on. Jimmy at least gets to shower first but he takes forever and Haley isn't having it. She walks in on her step-brother and catches him jerking off! Haley offers to finish him, if it'll speed things up and free the shower. Jimmy is surprised but accepts the offer and Haley begins to jerk her stepbro's big boner right there in the bathroom. She pulls her tits out to help him a bit and even drops to her knees to suck her step-brother's cock. But Haley gets horny and tells her step-brother they should go to the bed together. Jimmy eats his horny little step-sister's pussy and then thrusts into her from behind. Haley is impressed with her stepbro's big dick as he pounds away at her tight little pussy. Haley rides her stepbro, twerking her little butt all over his cock. Jimmy fucks his step-sister real good, making her cum repeatedly on his stiff knob. He finishes by nutting all over Haley's face - she excitedly runs to get her turn in the shower now!
