Leo, engrossed in his book, is startled by his cousin's oily fingers tracing his cock through his shorts. She's lubed up, ready, and hungry. "I've been watching you, Leo," she purrs, "I know you want this." She pulls out her greased-up ass, rubbing it against his hardening length, her slick juices soaking through his clothes. Leo, unable to resist, grabs her hips, pulling her closer as she moans, "Fuck me, Leo. Make me your oily, ass-fucked cousin."
