A beautiful day began in a big Pokémon daycare in the Unova region. After spending a few months on the warm and paradisiacal beaches of the Alola region, our Pokémon breeder returned from his vacation and started a new day in his apartment. The caretaker was called Sean and lived with other workers in a small neighborhood where he had the job, a 10 minutes from his apartment. Her boss was very proud because she could tranquilize the most aggressive Pokémon with his "special care treatments". Some of them were more tenacious than others and after his "treatment", Sean was always accompanied by many Pokémon. Sean went to the bathroom to take a good shower before he started his work. Her boss only gave him permission from his "training and special care" when he had a lot of work and gained very fast the confidence of the Pokémon he cared for and trained. Sean comes out of the bathroom with a towel tied around his waist and went to the kitchen to prepare his lunch but suddenly someone knocked at his door. When he opened the door was Phil, one of his companions with an Alolan Vulpix on their arms.

"Good morning, Sean. Did you sleep well today?" asked Phil with a sleeping face seemed that he slept nothing during the night.

"Yes, I slept perfectly. Something happen? You caught me coming out of the shower." says Sean

"Well, one of our classmates tried to do a special treatment last night but he didn't notice that some Poison-Type Pokémon have the Poison Point ability and is now in the hospital." said his companion.

"Oh, my. But they only do it as self-defense. You have to be very careful when is time to treating them. A Nidoqueen poisoned me accidentally and then she went for a Pecha Berry to cure me. Since that day, I treated many Poison-type Pokémon and I'm immune to poison. I hope our partner will recover soon. Are you hungry? I'm going to prepare breakfast." says Sean

"Oh, all right, thanks." says Phil.

He left his vulpix on the ground and entered in his apartment. Sean went to his bedroom to get dressed and then prepared a big breakfast full of energy for both of them, because today they had a lot of work and could not fall to her boss. After breakfast, they left for work. When he arrives, many Pokémon were happy to see him and wanted to train with him but first he had to do the tasks he had been assigned. Sean went to pick up the keys to the store while the Pokémon group was following him.

"Come on guys, your special training we'll do it later. Go play with the other caregivers." said Sean

They all went a little sad for not training with Sean while the caretaker was going to get the keys. Walking down the corridors, he found another colleague of his, Martin, who had started a few days ago and helped him to guide him through the place. Sean arrived to a big rest room and there was a blue door separated by other two that were the toilets. Sean marked a code to unlock the door and the two came in to pick up what they needed. Sean found the keys to the store while his partner couldn't find the key that he needed.

"Sean, Which one is the key to the mating room? Is the one with a heart keychain, wasn't it?" Martin asked.

"Are you there today? Many of them become very aggressive when it is their mating season. And by the way, is the keychain that has a female Pikachu not that." says Sean to Martin that he had other key with a Garbodor's keychain.

"Oh, my bad. This is the key to the garbage. All right, thank you very much." said Martin.

His partner left for his job while Sean was on his way to the huge warehouse to review and replace everything that was missing. Before entering to the warehouse there was a screen where he had to write down the manager name that was doing the task for that the other employees know who did it. Sean completed the pages and with the list that he had picked up earlier in her boss's office, he went inside and started doing the inspection.

"Let's see... I think it will be necessary to organize the warehouse again because there are many things that are missing..." thought Sean checking the shelves full of materials, utensils and cleaning products that had while he's walking between the narrow corridors.

Sean continued to review the huge warehouse and entered in a huge cold chamber where the berries and energy shakes were stored for the Pokémon. As he left the cold chambers, Sean finished scoring all that was missing and saw a Snivy waiting for him.

"Oh, hi. I haven't forgotten about you. Let me close the warehouse, make some calls and start your training." Sean said.

The Snivy only nodded staring at the huge bulge that was marked in Sean's trousers. He was very envious of seeing that huge cock for a normal human and wanted to have it just like him. Many Pokémon who were in the place told him that he was the best caretaker of the Pokémon daycare. The Snivy thought without stopping to look at Sean's crotch while they were back: "If I train with his penis, I will be as big as him when I evolved into Serperior?"

Sean left the keys to the warehouse and went to the front desk to get the list of the Pokémon that he should train. When he checked the list, he found out that Snivy wasn't on the list.

"He'll probably be in charge of another caretaker. I'll go to get him for know that I'll take care of him by myself." thought Sean.

The Pokémon breeder left with the Snivy in search of the caretaker and found him training with a huge Goodra.

"Hey, Louis. I came to tell you that the Snivy you have to train, I'll take care of it." said Sean.

"Understood, but you must give me one of your list to change." said Louis.

"In which of them are you interested? I have many Fighting-type Pokémon." Sean said.

"Let me see the list." said Louis.

Sean delivered the list and his partner looked at the Pokémon he had. He showed interest in Medicham and made the exchange. The two caretakers left to train with the Pokémon assigned to them while the hours passed quickly. The night came and almost all of Sean's Pokémon evolved except the little Snivy that was a little more difficult to evolve. Some of them were more difficult to evolve because they disobeyed their orders or attacked them but with their "special training", he relaxed them immediately. He was always the last one out of work as the Pokémon loved being with him. At the end of his turn, he went home to replenish his strength. Six months passed, since Snivy trained with Sean using his "special training was the only Pokémon with which he had more difficulties. He was a very obedient and affectionate Pokémon but it was hard for him to learn new moves. After the meal and completed the training with the Pokémon that had been given, he reserved a training room for only with the Snivy. Sean trained hard the Snivy until he finally evolved to Servine. The grass-type Pokémon seemed very happy but smiled slightly looking at the crotch of his caretaker.

"Well, I think you still have some strength left for a special workout. Are you ready?" asked Sean.

The Servine pounced on Sean lowering his pants and underpants showing the huge cock of his caretaker. Sean sat on the floor resting his back on the wall and the Servine began to lick his cock as if it were a lollipop. Then he began to suck everything that his mouth could contain. Sean watched as the Servine started using Wine Whip to masturbate his huge cock until he started to cum in Servine's mouth. Sean looked at how he swallowed everything and his stomach began to swell quickly, raising Servine's level at a dizzying speed while the cum came out all over his mouth.

"Relax, there's no hurry. Then we'll have a good shower." said Sean.

After a few hours of special training, the Servine was satisfied and full while Sean was going to the locker rooms to shower and go home. When he finished changing, took the Servine with the other Pokémon to rest. The Servine saw that his cock had increased in size and went to rest as tomorrow would continue with his training. Another six months passed, and Servine was always the last one since his caretaker was more time with him even on his breaks. After each workout, another caregiver made him exercise to lose weight even though he was not very happy. One day, Sean was in the cafeteria and Servine had followed him to continue his special training but Sean had done it a few hours ago. The caretaker sat in one of the seats and began to eat quietly. The Servine with his Wine Whip pulled down his clothes and licked his lips. He uses Grass Knot to immobilize his legs so he could not escape and opened his mouth, starting to suck the cock to his caretaker. Sean was surprised and looked under the table and saw the Servine sucking the cock. His legs were immobilized and he couldn't escape.

"What are you doing here? Aren't you supposed to be exercising to lose weight with another caretaker?" said Sean

The Servine was concentrated in sucking his cock and suddenly his body began to glow up. Sean saw that the Servine grew and increased in size, throwing the table and chairs around the floor until his evolution had ended. He was now a huge and obese Serperior but that meant that his training had to be more intense than before.

"Serperior, be a good boy and stop. We've trained before." said Sean.

The Serperior ignored him and continued to sucking his cock until he cums in his mouth. The Pokémon cheeks swelled but Serperior learned a new move, making him swallow it right away and Sean cums very quickly as if it were a hose. Sean covered his mouth to not scream as he was using Giga Drain to swallow up the last drop of his huge ball. The Serperior stopped and hugged Sean with his body. His cock was almost as big as his caretaker and Sean decided to take him to the gym to do exercise because he was fatter than his previous workouts. Once ordered the cafeteria, he took him to the gym for another caretaker take care of him. Sean went on with his tasks until he came home. Two weeks passed after Servine evolved and Serperior was already an addict to Sean's special trainings. Every time that he saw him alone, the snake tried to catch him and be able to do extra workouts with Sean. The caretaker tried to avoid him but even though the Pokémon was fat, he had a great speed. After many failed attempts to dodge the Serperior, Sean decided to rest for a moment in a tree but in a few seconds the caretaker would be ambushed again. The Serperior with his Wine Whip, destroyed his clothes and began to suck his cock quickly. Sean could not react in time and was subjected by the snake for a long hours.

"Serperior, you've become an addict. This is the ninth time you do this! Aren't you going to get tired?" said Sean.

The Serperior continued to sucking his cock ignoring his caretaker and his only goal was to swallow his cum and that his penis was the biggest of all the pokémon daycare. He wanted to be king of the place with the biggest cock. After several Giga Drain, the Serperior already seemed satisfied. Now that his cock was the biggest, his next goal was to find a partner. While the obese Serperior was leaving, Sean was able to get up but his legs trembled because of the intense blowjob that the Serperior had made to him.

"Looks like I'm done with Serperior. Now I can take care of the other Pokémon." said Sean

Sean returned to the locker rooms to wear new clothes while the Serperior was looking a mate. He found an attractive female Serperior shiny with other Serperior but seemed to have a lot of competition. He approached but was attacked by the other males. He attacked them, too, but the females seemed to be bored with so much fighting. One of the Serperior showed his cock to show that he had it bigger than the other rivals. All the males did the same and the females began to show interest in them again. He was the last one. Everyone made fun of how fat he was and believed that his cock would not be enough to seduce them but he just smiled and began to have the erection. Bit by bit he overcame his rivals but also began to surprise and intimidate the females for his massive growth. His cock continued to grow until he compared his cock with the other rivals and was very convinced that the Serperior shiny would be interested in her. The males were stunned and saw that all the females had fled for unknown reasons. The other Serperior were angry with him and went behind them, leaving him behind but he would not give up. The months passed and Sean while was working, he looked as the Serperior tried to seduce a female and was successful. He was no longer fat when he trained him and the other caregivers gave him all the affection that he needed. The hardest thing was mating. Of all of them only a huge Aurorus could with him. After many attempts, the Serperior could mate even though the Aurorus fainted when the Serperior ended. They were couple months but in the end, the Serperior began to lose interest in her and decided to look for his caregiver. He looked everywhere but he couldn't find him anywhere until he went back to the locker rooms where he found Sean taking a shower. The Serperior slowly approached to the caretaker and coiled him with his body, surprising Sean.

"Hey, big guy! What are you doing here?" asked Sean.

The Serperior had a huge erection and smiled his caretaker with a big smile.

"Oh, you want to thank me for the special training? How naughty you are." said Sean.

The Serperior him rammed his huge penis in his butt and seemed to fit him like a glove. It was better than Aurorus. In a matter of minutes he started to cum, making a large pool of cum on the ground but it was only his first round. His stomach began to grow and the Serperior continued to cum without stopping.

"So much energy! You're going to flood the whole locker room. Luckily, I'm the last one to out of there and there's nobody here." said Sean

The Serperior continued to fuck his caretaker for a few hours and his tummy was really bloated until he can't contain more and every time that the Serperior cums, a small waterfall of cum came out of Sean's butt flooding the changing rooms. Finally, the Serperior was happy and satisfied with his training. Sean's belly was really heavy and so big that his clothes were narrow but luckily had wider clothes as many Pokémon made him that kind of gratitude. Finally, Sean took the Serperior with the others to rest and went home. A few weeks later, Sean realized that the Serperior was gone and he was informed that his trainer had already come for him. Who will be the next Pokémon to train with caretaker Sean? Who knows...?
