Simon tossed a stick across the yard and Sparky instinctively chased it. Mike whimpered but followed the bitch, trying to catch up to her and suckle. Sparky kept nipping at the pup, at five months he was ready to be weaned. Sparky brought the stick back and Mike was on her instantly.
Simon was intrigued by his brother's persistence. He hesitated before throwing the stick again, an idea growing in his mind. The dogs went out again, same thing. Sparky tried to concentrate on the task at hand and Mike chasing her. When the dogs came back this time, Simon picked his brother up and carried him over to a lawn chair.
Sparky looked at the boy, but Simon just tossed the stick away. sparky ran to the back of the yard to try and find it. "So, Mike's hungry, huh?" Simon opened the zipper on his shorts and fished out his engorging member."Here you go!" Mike, his last vestiges of human intelligence aghast at what he was about to do, instinctively licked his brother's cock and began to suck fiercely at it.
Simon moaned as the the boy-dog got more and more enthusiastic. "Oh, yeah! Good boy!" Mike gulped. He didn't have a choice in the matter for now. Having his brother's velvety young cock in his mouth was a strange sensation. It's shaft throbbed against the puppy's cheeks as the pre-cum trickled down his throat.
Simon's body jerked as he came closer and closer to cumming. At last his man-juice gushed forth, choking his brother in one final, violent thrust of orgasm.When Simon recovered, he pulled the puppy away from his cock and set him on the ground. "That was great! I think I'll enjoy having my very own....cock-hound!"
