By fighting back

It was obvious that the street rat wasn't going to calm down any time soon, and the Doberman won't jump in to protect Ali, so he had only option, to fight back.

The rat ran up to Ali, trying to punch his for a second time, but this time Ali was prepared and dodged out of the way, the rat's fist hitting the trash can behind him instead, making it fall over and spill garbage on the ground. Ali pushed the rat back, before readying up a punch as well. The rat saw his attention, and decided to block his blow with his arms, Ali's punch hitting one of his elbows, dealing little to no damage. With his attempted attack failed, Ali retracted, getting himself into defensive position, already knowing that the rat would strike back.

Just as he predicted, the naked rat jumped at him, Ali was expecting another punch, but the rat instead chose to tackle him with his fat body, making Ali fall back to the floor. The Doberman watched the little brawl with a big smile, while Ali was fighting someone with much more experience than him. He tried to get up on his feet, but the rat tackled him again, pushing him back down, before getting on top of him, planting his fat butt right on his crotch and grabbing his arms. Ali had gotten completely pinned under the fat, naked rat, he could see him stare down at him grinning, while his soft cock slowly started to harden.

„Pfff, what a guard you are.” The rat said mockingly, while Ali struggled against his grasp, trying to get free and push him off, but not succeeding. The rat's strength was higher than his. „Maybe you should have kept walking, pup.”

Ali stared up terrified and panicked at the rat, who was looking down at him smiling with an evil grin. He couldn't free his hands from his grasp, his fat butt was too heavy on top of his chest to push him off, he could only move his feet that were not yet pinned under him.
