Lucky sighed, his chin resting on his paws, his ears drooped to either side. He hated visiting the vet, and yet, somehow he ended up there. At least twice a month for something stupid he had decided to do. Jump off the tallest tree at hiccup hole. Ride the wagon down the hill at the bar. Explore the inside of the tractor. Humph. And everytime it was the same old doctor, the same old precedure, The same old annoying office: Round, with steal counters, and tables lining the walls, the brown door with the stained name, the creepy looking untinsils around him, and always and the same old stupid, untasty puppy treat she gave him at the end. So when the vibrant, young brunnette walked in holding a stehoscope, Lucky's ears perked in curisoity. Who was she? What was she doing here? Was she the doctor's assisnt?

"Hello puppy! I'm the doctors assistant!" She say in a extra bubbly voice. Lucky cringed.

"My name is Veronica, and I'm here to make you allll better, puppy wuppy. " She cooed. Lucky growled quietly, rolling his eyes. OH great, the last thing he needed was this stupid baby talk. His sholder was giving him some problems, but other then that, he didn't feel any need to be at the vet. The baby talk was just making things worse. The nurse walked over to the nearest counter, and picked up a small chart, reading it over.

"So, Lucky, not feeling to well hmmm? Well don't worry, I know your scared, but I'm here to make you feel alllllll better!" She giggled. Lucky rolled his eyes again. The nurse walked over to him with her little mini flash light, and proceeded to check his ears, nose and eyes with it. All proving to be normal, save for his left ear, which she found a small cut.

"Oh dear...who knows how long THATS been there. Oh well, we'll clean you up and fix you up, ok puppy wuppy?" Veronica askjed. Lucky groaned. He was going to be sick if she kept talking like that. She walked over to something, out of view, and Lucky was left sitting on the cold table, mumbling quietly to himself about stupid nurses, and annoying tests. When the nurse returned, she was holding the themometer which only made Lucky feel worse. He didn't dread the themometer like other dogs, but he did find it a gross annoyance. He sighs and slipped into position without even asking, lowering his front pass and chest to the cold steel table, and lifting his butt in the air, tail up. The nurse gasped and reached a hand down, gently rubbing his back.

"Ooooo, what a good puppy! Wow, your really smart!" She giggled. Lucky sighed. He was wishing she would just hurry up with the themometor and get it over with when he felt it. The cold, sticky dabbing of something against his tight little tail ring.

"Wh, what is that?!" Lucky yelped, but his voice olny turned into a quiet whine when it reached human ears. He REALLY yelped when he felt it push into him, the thick, vasiline coated finger that wormed it's way into his bottom, making his toes curl. GEEZ, talk about an invasion of privacy. His eyes wide, he scrabbled at the floor with his paws, but the nurse held him still, making sure he didn't go anywhere. The pup whimpered , wriggling about as the slim pinky continue to gently pump in and out of Lucky's tight behind. And after a few seconds of discomfort, and Lucky was finally getting used to the violating digit, it left him, suddenly giving the spooted dog an empty feeling inside.

"Now hold still." Veronica hissed, before something much large began to press into his little opening. It was cold, and round. The themometer, of course, but Lucky had never felt anything like it before! It was huge!

"NGRRGGHH!!" Lucky whined, trying to wiggle his bottom away from the impaling device, but the nurce held him steady.

"Shhh, shhhh, just a little moooore." She whispered, twisting the huge object deeper into Lucky's tight rump. Lucky whimpered quietly. Strangly enough, there was no pain, and the discomfort he did feel, was ebbing away into something else. Something that was diffrent then pleasure, kind of like a fullness that wasn't so bad. He grunted quietly as it rammed itself a bit deeper into him.

"That's all of it!, Now just hold still..." The nurse said, as she walked over to the sink and washed her hands. Lucky sat there, well, he wasn't really sitting. He was leaning, chest to the floor, butt in the air, in the most vunerable position he could think of. How embarassing. And with that huge themometer sticking out of his behind like that. Lucky could feel his cheeks flush with embarassment. Geez, how did he get into this position...And soon, the nurse was back, standing next to him, smiling.

"Awww, don't be shy, that's natural." She whispered, while Lucky's ears perked. What the hell was she talking about.

"This will make things much easier, actually." She explained, and Lucky suddenly felt something very warm, and very tight wrap around his erection. Erection?! Wait a minute, when did THAT happen? Lucky's thoughts however, were suddenly disrupted when the tight hand around his cock began to massage, stroking his little shaft slowly. He cooed in pleasure, his ears held back, his tail flipping about behind him.

"Shhh, that's it, good puppy." She whispered while she masturbated him. Lucky never felt anything like it before! The human hand was giant around his cock, and so warm and tight, he wouldn't last long at all. Infact, he could feel his hips bucking against the human fist by themselfs.

"Awww, are we gonna make a mess?" The nurse cooed again, but Lucky didn't even hear. Then something new happened. The something pressed against te huge themometer, pressing it deeper into his rump, and Lucky couldn't hold it anymore. He yelped, eyes lidded, several, several hot bursts of puppy cum blasted across the floor all over the place, and Lucky nearly melted under the pleasure. Infact, the rest of the appointment was a blur. His legs felt like jelly and everything she said to him afterwards, seemed like it was coming from somewhere far away. Infact, he's even sure he got a shot in there somewhere, but really, the young pup didn't care.
