As the dawn breaks, a tattooed goth girl stirs in her sleep, unaware of the volcanic eruption about to happen. Her step-brother, horny and eager, positions himself behind her, his massive cock ready. In the tight confines of their RV, he pounds her doggy style, her big, inked ass jiggling with each thrust. He cums four times, each load coating her backside, dripping down her thighs. She wakes just in time to feel the last surge, groaning softly as he marks her as his.
