With suitcases sprawled across the bedroom, step-siblings are in a rush to pack for their holiday getaway. While folding clothes, the stepbrother can't help but stare at his sister's plump, round ass in tight shorts. She catches him, playfully bending over to give him a better view. He can't resist, moving in to slap and grope her big butt. She moans, pushing back against him, then turns around to unzip his pants, revealing his throbbing cock. She strokes it, then takes it in her mouth, deepthroating him. He picks her up, placing her on the suitcase, and fucks her hard from behind, her big ass jiggling with each thrust. She screams in pleasure, spreading her ass cheeks, encouraging him to go deeper. He does, slamming into her until he creampies her pussy, their vacation plans now including a lot more than just packing.
