Isaac shifted a bit as the heat finally took over. His eyes glowed and his claws dug into the wall in front of him. He focused on Scott's paw over his own. He howled as Scott's thick member scraped across his small bundle of nerves. He whimpered as he feel Scott practically pull all the way out, only the howl again and pant like a bastard in heat, which he was, when Scott slammed back into him.

He saw stars and he craved more. He built up speed, and moved in time with Scott's thrusting getting the maximum pleasure for both of them. Isaac clenched the muscles in his ass creating a vice like grip around his member. His own cock was rock hard and throbbing, leaking precum all over the stall wall even without any stimulation on his cock.
