My girlfriend, dressed in nothing but a negligee and a hungry smile, straddles me on the couch. She grinds against my hard-on, her wetness seeping through the thin fabric. I grab her hips, guiding her as she rides me, her tits bouncing enticingly. She leans back, exposing her neck, and I suck and bite, leaving marks. She moans, her pussy clenching around me. I can't hold back, and with a final thrust, I fill her with my hot cream, my hands gripping her ass tightly.
