Your girlfriend was using your laptop and found your porn folder! She's not mad, but she deleted everything and replaced it with a video of her own. Your cum belongs to her, this is the only porn you'll need from now on. She changes into lingerie with garters, stockings, and heels. She teases you and strips off the bra and panties, and starts spreading for you. She starts fucking herself with a dildo, getting creamy until she finally cums hard on the dildo. She figures you've probably already cum, but she wants every last drop, and instructs you to keep jerking off for her while she spreads until you cum again.
