Two straight brothers, alone and horny, decide to trim each other's balls as a test of their manhood. As they strip down, their thick cocks tent their boxers, betraying their excitement. They start carefully, but soon their hands roam, caressing each other's massive dicks and heavy balls. One brother, curious and bold, takes the other's cock into his mouth, sucking and stroking until his brother can't help but spank his ass, encouraging him to ride that thick cock. They moan and thrust, their taboo lust consuming them.
