Two innocent sisters, driven by curiosity and hormones, sneak into their brother's room while he's in the shower. They find his massive cock standing at attention, left unattended on the bed. Overcoming their initial shock, they can't resist the temptation and kneel before it, their young, untouched mouths stretching wide to engulf the throbbing member. They take turns, exploring the new sensations, their tight lips sliding up and down the shaft, leaving trails of saliva.
