With a primal grunt, the dominant top pushes his hefty, rock-hard cock into his partner's ass, inch by inch, until fully sheathed. The bottom gasps, feeling every vein and ridge as the cock fills him completely. The top begins a relentless rhythm, his hips slamming against the bottom's ass, driving his cock deep. The bottom's screams of pleasure echo as the top's balls slap against his taint, leaving red welts. Cum leaks from the bottom's ass, mixing with sweat, as the top's thrusts become more urgent, chasing his own release.
