My big-ass stepsister catches me masturbating with her panties in her room. She struts over, her round ass swaying. "You like my panties, don't you?" she asks. I nod, unable to answer. She smirks and slowly begins to strip, revealing tight curves and a juicy ass. "Why don't you have some fun with both of them?" She hands me her panties and climbs onto the bed, presenting her tight asshole. I slam my cock into her, making her gasp. It fits perfectly, stretching her anus with each thrust. Grabbing her hips, I pound away, hitting that sweet spot inside her. Her walls clench around me as she cums, moaning loudly.
