Two straight best friends, bored and alone, decide to pass the time by exploring each other's bodies. One starts by gently stroking the other's cock, feeling it grow hard in his hand. The recipient, hesitant at first, soon gives in to pleasure, pushing his hips forward. They move to the couch, the top spitting on his palm to lube up his buddy's throbbing dick. He straddles him, sliding down onto that thick meat, taking it deep. They grunt and sweat, fucking hard, their friendship evolving into something raw and primal.
