Brazilian cousins, bored and horny, find themselves alone in the house. They start masturbating in separate rooms, the sounds of each other's pleasure echoing through the walls. One cousin, unable to resist, sneaks into the other's room, catching him mid-stroke. They lock eyes, both rock-hard and eager. They continue jerking off side by side, their hands working feverishly, until they both explode in simultaneous, messy orgasms.
