In Juarezfist's explicit "Fist Fu," two aggressive gay men exchange blows of the fisti-cuffs, trading deep, powerful thrusts. One man, fueled by lust, forces his entire fist into his partner's gaping ass, knuckles-deep, as the other takes it like a champ, his own dick rock-hard and dripping. The room echoes with their grunts and the wet, slapping sounds of flesh meeting flesh.
