Dan grows a sheath

    by: The GrandDuke of Owls Author IconMail Icon
Dan continued to try and resist the unbelievable urge to have sex with his girl friends dog, as they continued to talk about their plans for their dogs. Just when he thought he was about to give in, Dan felt a tug on the leash and realized that Kat had finished talking with Jen and was starting to walk home. He quickly got to all fours and padded after her. She looked down at him with a smile and said,

"You looked like you were enjoying yourself back there. Don't worry, we made arrangement for the two of you to meet and really get to know each other."

Dan listened with horror at these words, "You wouldn't! I'm not a dog! Please just let me go!"

Jen just laughed at him. "Why would I let the family dog go? Oh, you will have that bitch, and from what I saw earlier you will like it too. Now come on, we have to go home and get you ready for your date tomorrow."

Dan spent the rest of the walk home trying to figure out how to get out of the mess he was in. His thoughts kept getting interrupted though by his new nose which was extremely sensitive. Every once in a while he would smell dog urine, or some other scent and start over to it to get a closer look until he realized what he was doing and forcing himself away. Every time this happened, his sister would just smile, knowing that it wouldn't be long until his mind was completely canine. Dan breathed a sigh of relief until his Mom looked over and said, "Did he do his business? If he goes in the house again we will have to chain him outside."

Dan looked at Kat with outrage when she said, "No, he only peed and didn't poop. It may be safer to just leave him outside for the night."

Dan said "I'm not sleeping outside like a dog! It's supposed to rain tonight!"

Kat ignored I'm and said to their mom, "I'll just take him out to his doghouse then."

With that she gave a tug on the leash, but Dan had sat down, trying to stay inside. "I won't do it!"

Kat just looked at him sternly and said, "Dan, heel!" Intently all of the muscles in Dan's legs uncurled and he rose to all fours obediently following her out the door. He felt his body moving but he couldn't stop himself. As soon as they were in the back yard, Kat looked angrily at Dan.

"Don't you ever disobey me again!" she said

"Disobey? I'm NOT your dog I'm your brother! I'm a human being!"

"That's funny. You still think of yourself as a human. Hate to break it to you but humans don't have tails or sleep outside" then she smiled and winked at Dan, "And certainly don't go around licking their cocks."

Dan suddenly felt like his cock was on fire. He let out an oddly high pitched yelp but the pain went away just as quickly. He then sat down to inspect his cock but looked normal. Looking at it he was over come with an urge to suck on it. He struggled to stop himself but could feel his back curving lower forcing his mouth closer toward hit prize. With his mouth barely an inch from his cock he stuck out his tounge and began to lick at it. As he did, a bunch of skin began to move up from his groin covering his cock and sealing it in a sheath. This didn't stop Dan though who continued to lick at his encased cock with a passion. The tip of a thin red cock emerged as his lick brought jolts of pleasure to his core. He could feel himself about to cum but this excited him even more, licking away at his new dogie cock. His ball churned letting out large amounts of canine sperm into Dan's waiting mouth which he happily swallowed. It was only then that Dan came down from his lust looking around in horror to find that Kat had tied his leash to a dog house and left him sitting outside.
