Catching your step-sister masturbating can be a turn-on. These two step-siblings were left home alone by their step-parents. Since the two are sexual freaks, fucking each other's brains out wasn't such a taboo to overcome. She was eager to melt that stiff long prick with her mouth and pussy, he was eager to cum all over her mouth. Once they got to bed, after all the other sexual activities they had, they fucked with zest as only step-siblings could.
