Jack Waters and Rob Quin, twink stepbrothers, find themselves alone and horny. Jack, the older and bolder, suggests a game of measuring their cocks. Rob, hesitant at first, gives in to curiosity. Their hard dicks slap together as they compare lengths and girths, pre-cum leaking. The competition heats up, and soon, their mouths are wrapped around each other's throbbing members. Jack's massive cock stretches Rob's tight hole, raw and unprotected, as they fuck in every position, their moans filling the room. The taboo of their step-family relation only intensifies their passion.
