Joe, engrossed in his game, is startled when Jenny, his fiery-haired stepsister, reaches over to stroke his cock. She watches his screen, her eyes flicking between the action and his growing bulge. Her tattooed arm moves rhythmically, her small tits heaving with excitement. Joe's breath hitches as she twists her wrist, speeding up, her red hair cascading over her shoulder. She leans in, whispering, "Cum for me, big brother." Joe's body tenses, his load shooting onto her eager hand as she milks him dry.
