In the dim light of the Colombian afternoon, Mary and her uncle Carlos share a secret glance. Carlos, a rugged, older man, has always been a source of fascination for Mary. Today, she's dressed to impress, her curves accentuated by her tight dress. As they talk, Mary's hand brushes against Carlos' thigh, lingering. Carlos looks at her, understanding her silent invitation. He leans in, kissing her neck, making her shiver. Mary turns to face him, their lips meeting in a hungry kiss. Carlos' hands roam her body, squeezing her ass, making her moan. He pushes her dress up, revealing her smooth, tanned thighs. Mary reaches for his belt, unbuckling it, her hand slipping inside his pants. Carlos' breath hitches as she grips his hardening cock. He lifts her dress fully, revealing her black lace thong. He slips a finger beneath the fabric, feeling her wetness. Mary bites her lip, her eyes fluttering closed. Just as Carlos is about to push her thong aside, a knock at the door startles them. They quickly compose themselves, their hearts pounding, their bodies aching for more.
