Hottie Camie, my girlfriend's sister, is a tease. She knows I'm watching as she changes into her skimpiest outfit, her young, round ass and firm tits on full display. She catches me looking and smiles, biting her lip. I can't take it anymore. I push her onto the bed, her laugh turning into a gasp as I tear off her clothes. She's wet, her pussy glistening. I shove my cock inside her, making her cry out. She's tight, her muscles clenching around me as I pound into her. Her fingers dig into my back, her nails drawing blood as I fuck her harder. She comes with a scream, her pussy contracting around me, milking my cock as I fill her with my cum.
