Brazilian cousins, separated by a thin wall, can't resist the temptation. They start masturbating, their moans echoing through the shared space. One cousin, hearing the other, becomes curious. He stands up, cock in hand, and sneaks a peek. Caught in the act, they decide to take it further, both stroking each other's throbbing erections. The room fills with the scent of sweat and precum as they grunt and groan, their bodies tensing with pleasure.
