Ian was coming home off the bus when his mom was just getting back from walking their dogs to the nearby dog park and back. This was probably when the trouble began. His mom walked some of the neighbors dogs along with her, pride and joy daisy. The family’s only dog, who the mother loved and the father didn’t really particularly like. She enjoyed Ian’s company so he never minded her, she often napped on his bed while his parents were at work, only Tuesdays and Fridays were days where they both home before he got off school, usually it took till 8… Ian went as usual to his room opened his laptop and opened YouTube watching videos till the next day. Daisy hopping in the bed and giving him a few sweet licks on the cheek,
The family knew they never fixed the dog, and she would go into heat occasionally, this was never an issue for the family who was usually prompt to give her diapers, shooed away any males and figured in the long run they were saving money. But this time was unexpected, Ian awoke in his bed hearing lapping sounds coming from nearby, looking up and wiping his eyes he saw daisy licking her cunt with a fervor beside his bed on the carpet, his parents always swatted at her and made her stop but his emotion was more of fascination, he had never seen what happens if she kept going, watching her breaths get faster and faster he felt his already solid morning wood flex and rush. She licked harder and harder at her swollen cunt till she whimpered, shook, and looked very happy. He just watched her cum, why was that so hot? He thought. Before he knew it she was licking again. Damn she really needs it bad he thought! His parents had went to the farmers market, his older brother and his girlfriend were upstairs. Alone. He went to take a shower gathering his clothes, stripping before he left. As he was lifting his shirt from the clean hamper it was slightly covering his face daisy seized her opportunity and gave his soft dick a lick! This sent shivers up Ian’s spine and the warm tongue felt so good, but one lick was enough! Ian pulled away rushing to the shower not thinking to scold her, but never thinking of this idea before! He pissed feeling a little odd he he lifted up a foot and felt freer hiking his leg. Hoping in the shower he quickly washed, then his mind got carried away with him he began thinking of daisy… her heat, how he felt he could almost… smell her from here… his young prick rising to attention along to his heartbeat. He would want to hurry if he wanted to do anything at all before his parents got back which could be anytime! He turned off the hot water and dried off, not putting on any clothes he ran through the hallway to his room. Unable to find daisy, he reluctantly decided to try to go find her nude instead of searching through the clothes. Knowing he was pretty much home alone as his brother and his girlfriend never left their room. Sneaking around looking for daisy he almost turned back his mind becoming conscious of just how weird this was. When, daisy came trotting in from the room behind the stairs, he could smell her he realized and with that he called her to him and took off toward his room her following at his heels. When they got in he shut the door and opened the blinds to make sure his parents were not home. And looked over daisy, her tail was hiked unusually, probably from her heat, she was panting and happy, he ran his hands all over her his dick rising as he thought about her hind legs he moved his hands closer to her snatch. Feeling for the first time ever a vagina he was so hard, it was warm and swollen… begging for something to be put in as he was inspecting her pussy she turned around and licked his dick again sending shockwaves of pleasure throughout his young body, he got an idea. He played her in his belly with her legs spread and as she licked his ready cock he plunged himself into her cunny, making her hump his face and whine. He couldn’t get enough she tasted wonderful, not aware of his change at all he scooted her down her getting the message practically did everything herself sitting on his young cock, Ian felt some deep primal urge within him, something he had never felt before, he HAD to mate with her, breed her, give her his puppies. He MUST. Plowing hard and going to town he didn’t notice his new knot, slap slap slap Pop! Aaaauuuuuuhhhhh he moaned as he came deep within her, only it didn’t stop. Pulse after pulse kept filling her up. He then tried to pull out but couldn’t every movement making his member more and more sensitive it felt the best to stay still and let it pump, which felt very good. He didn’t know why he was stuck but he did notice fur all over his crotch and belly, he couldn’t see his face was already slightly morphing, no time to react He suddenly heard a door shut! His parents were home. He quickly covered up with a blanket and played down on his bed with his dick stuck in the dog below him. Panting heavily, each spurt driving him mad with orgasmic energy. He almost couldn’t contain his will to moan and whine, hairs were deputing in his arms and face now, he reached and turned off the light and had just enough time to lay back down acting like he was napping which he often did on Saturdays. And his mom checked the room over and left for the kitchen.he could hear her asking where daisy was before pouring some food in the dog bowl. Oh no! He thought he felt her begin to rise up and pull on his knot, it felt like she was going to pull his dick off, here daisy! Pop! She licked herself a few times and ran toward the food bowl. He looked up feeling happy dizzy, a little worried but almost inebriated he couldn’t make heads or tails of his situation his dick looked weird now it was pointy and there was 2 swollen balls in either side of the base like extra testicles, it continuously bobbed up and down as it spurted more cum, transforming him more and more by the second he looked at his hands which were paws and back again at his butt to see a new tail. He cried, he knew he couldn’t tell anyone they would find out what he did somehow thinking it was that. He couldn’t think straight so at one point he just gave up. Collapsing into all fours as his transformation completed. His family unaware. He ran out the doggy door on the side of the entryway by the room behind the stairs before anyone noticed.
