Mariela's fingers dance along her slick folds, her breath hitching as she teases her clit. She leans back, eyes closed, imagining Dario's touch. Lost in her fantasy, she doesn't hear him enter. Suddenly, she feels his gaze, hot and intense. She opens her eyes to find Dario watching her, his cock tenting his pants. Embarrassed yet turned on, Mariela invites him to join her, eager to turn their unexpected encounter into a steamy duo.
