I came home from work to find my stepsister lounging on the couch, her voluptuous curves barely concealed by her skimpy lingerie. She invited me to join her in a steamy threesome with her new sex doll, and I couldn't resist the opportunity for some amateur action. The moment we got down to business, the doll's fake tits and tight ass took center stage, as we indulged in some intense anal action. The sight of my stepsister in the throes of pleasure with the toy was a sight to behold, as she moaned and writhed in ecstasy. The climax was nothing short of explosive, as the doll's mouth eagerly devoured my throbbing member, leaving me in a state of pure satisfaction. This homemade FFM encounter turned out to be far better than I had anticipated, and I can't wait to do it again.
