The brother's massive cock, untouched until now, throbs against his sister's thigh as she tentatively reaches out to stroke it. She's a novice, but her hunger for him is undeniable. As she guides his cock to her virgin entrance, they both tremble with anticipation. Slowly, they begin to move, their bodies falling into a rhythm that's both sinful and exhilarating. The brother's cock slides in and out of his sister's tight pussy, their juices mingling as they give in to their forbidden lust.
