While at a sleepover around her friend's house, she hears her friend's hot Dad fucking his wife. She's always fancied the older man and hearing them fuck in the other room makes her so wet and horny. Desperate to cum, she waits until everyone is dreaming to raid the washing basket and finds exactly what she was looking for - his wife's panties, covered in his cum from where it leaked out of her pussy after they'd had sex. She immediately begins smelling and tasting the cum covered panties, before slipping out her tits and rubbing his still sticky cum all over her nipples. Playing with and tasting his cum gets her pussy dripping wet, so she slides her pajama bottoms across and begins to use his cum to tease her swollen clit. But... she needs to feel his cum inside her and desperately hopes that it might get her pregnant. She scoops up a few finger's worth of his spunk and pushes it deep inside her pussy, using it to masturbate. She struggles to stay quiet as she finger fucks herself with her cum covered digits, while licking the rest of his sticky residue from his wife's dirty panties. All that's left is a wet stain on them now where the ropes have soaked into the fabric... so there's only one thing left for her to do to make sure she uses up every last drop of the precious liquid. She struggles to stuff the huge granny panties into her tiny little cunt, but her wetness helps, and soon she's full to the brim with the huge panties. She rubs her clit, her pussy still sticky with his cum, until she reaches an intense orgasm with his wife's panties filling her from the inside. She pulls them out afterward and proudly shows off how clean and cum-free the material is now... now that it's all deep inside her little body.
