I endured one hour of gut punishment

I loved watching him endure those incredibly violent, brutal blows, without the slightest mercy.

Each blow was incredibly violent, whether it came from bare hands, boxing gloves, or a belt. He had no chance, no mercy.

I loved that the blows continued despite his attempts to stop them, always incredibly violent, without the slightest mercy.

Count on me to inflict even more atrocious torture on him, with brutal blows to the stomach, without the slightest mercy and without the slightest chance.
