Nik's enormous cock throbs in his sister's delicate grip, her tiny hand barely able to encircle it. Filessa's slender fingers glide up and down the length, her palm rubbing the sensitive underside, her thumb circling the swollen head. Her breath hitches as she feels him grow even harder, her own body betraying her as she becomes increasingly aroused. She leans in, her tongue darting out to taste his salty pre-cum, her eyes locked onto the closeup view of her hand job, bringing him closer and closer to release.
