The scene opens with Amy, a busty blonde in her thirties, lying naked in bed, breathing heavily. Her pussy is still dripping wet from the non-stop sex she had all night long, leaving her inner thighs sticky. She closes her eyes, trying to catch her breath, but can't shake off the intense orgasms that rocked her body. A figure approaches the bed, and she recognizes it as her younger sister, Sarah. Sarah, dressed in an indecently short skirt and no panties, smirks as she climbs onto the bed. She straddles Amy's chest and slowly grinds her pussy on her sister's face. "Enjoy the taste of your own pussy, sis?" Sarah whispers, her voice dripping with lust. As Amy tries to protest, Sarah shoves two of her fingers deeper into her mouth, causing Amy to gag on her sister's finger.
