Pipsqueak's fetish trouble

It was evening, like usual. Pipsqueak was used to this routine, having dinner with the princesses, cracking jokes with the royalty, then having intimate relations with his lover, the beautiful princess of the night, Luna. This time was different, though. Luna seemed very excited. Pipsqueak had to admit, he was excited too. As of today, Pipsqueak was now royalty.

Luna had adopted him after he was abused by his parents one night. He had been trying to keep it a secret that his parents were angry drunks to protect them, but after they nearly killed him this time, he had no choice but to tell somepony. Honestly, he was glad that he did. His parents had reached the point it would only get worse.

They arrived at the room and Luna opened her chamber's doors. The room was massive and adorable. The walls were pink and decorated with lots of white frills. The bed looked like a little filly's bed, only, in princess size. Pipsqueak smiled. Luna could be so adorable sometimes. Pipsqueak looked over at Luna as she closed the chamber door.

"Princess, aren't you going to make yourself smaller again?" Luna turned towards him and smiled. "Oh, Pipsqueak. not tonight. Tonight I want to try... Something different. Why don't you lay on the bed and wait for me while I get something."

Pipsqueak obeyed. He felt his belly fill with butterflies. This was exciting. He watched as the princess went to her closet to pull something out of it. It looked like a small frilly pink dress, appropriately sized for a young filly.

"I thought you said you weren't going to change your size tonight." Luna smirked slightly as she replied "I know." The dress flew over Pipsqueak and was suddenly forced onto him.

"W-wait! B-but I'm a colt!"

"Not tonight, you aren't," Luna said as she finished putting the dress on him. "Tonight, you're my little filly. My little foal, even."

Pipsqueak was taken off-guard by that last bit. "F-foal?" Before he could say anymore, he felt the skirt of the dress being pulled forward as The princess pulled some more items from the closet with her magic. A strap, no, several straps! A strange looking bottle, some cloth, a crib, and a pac-wait, a crib?! Pipsqueak started to get nervous. Was she serious? He was so worried about the crib that came out of the closet he neglected to pay attention to the several diapers that Luna had suddenly prepared to tape up on him. Once the first tape was pulled to secure the diaper, Pip snapped out of his focus on the crib.

Pipsqueak was about to protest when the princess had placed a pacifier into his mouth as a sort of substitute for a ball gag. "We don't want baby whining while we diaper her up, do we?" Luna said as she finished putting the third diaper onto the now helpless Pipsqueak. Then she decided it was time to allow some questions and pulled the pacifier away from his mouth.

"Luna?" "Yes, little Pipsy?" Pipsqueak blushed at the nickname. "Why are we doing this?" Luna perked up as he asked this. "Well, Pipsy, every night before, you were dominating me. I decided to make tonight special, and now I am the one dominating you."

Pipsqueak then felt something inside of him. He felt Luna's presence inside his body. She was using magic to fondle his insides! He started to worry a little before he felt her magic go towards his prostate. as soon as Luna's magic reached there, it started to massage his prostate, causing little Pipsy to moan audibly.

Luna let a smile creep over her face as she knew what to do next. She then used some magic to cover Pip's penis so he would be unable to blow his load, no matter how strong the urge to release. Pip felt this, and discovered that he rather liked being helpless. He actually liked being the submissive one.

Grrrrrrwwwrrrl!

Pipsqueak blushed a little as his stomach rumbled. He did have a rather small dinner tonight.

"Aww, is little Pipsy hungry?" Luna asked. Pipsqueak gave nothing more than a sheepish nod in response. "Okay, my little foal, drink up!" Luna said as she revealed her nipples to Pip. Pip stared, curious as to what to do. Luna laughed, "Come on, little one. Drink up!"

Pipsqueak suddenly felt his entire body being forced to crawl over to Luna. He felt his head being lifted up to stare right at her nipples. Was he supposed to suck on them? He decided that was what he should do and put his muzzle to one of the nipples before he started sucking. He was instantly rewarded with warm milk. It tasted strange, but for some reason, Pip didn't pull away. For some reason, he didn't want to pull away. he kept sucking on the milk that was rushing from Luna's nipples.

Pipsqueak finally got his fill from Luna and gasped for breath after a long while. Luna smiled and burped him. Pipsqueak was blushing furiously at this point. "Okay, little Pipsy, nap time"

Pipsqueak looked up at Luna and started to pout a little. "I don't need a nap! When are we going to-" he was interrupted by Luna sticking the over-sized pacifier into his mouth and strapping it onto him. Pipsqueak saw her float one of the strange bottles over but didn't pay it much mind. Bad idea. He suddenly felt something pushed into his butt and then he felt it fill with water. He was getting an enema! Pipsqueak quickly turned his head to see Luna smiling at him. Something seemed off about her smile. It was almost as if Luna actually BELIEVED Pipsqueak was her little foal daughter. Then Pipsqueak heard her sing something.

"Hush now, quiet now, it's time to lay your sleepy head..." Luna was singing a lullaby, and she was using her magic to make sure Pipsqueak got sleepy. It worked, and as Pipsqueak fell asleep, she put him into her old crib. This was already a great start. Soon, she would break him, and he wouldn't be able to resist. Luna then took her magic and instead of sealing his penis, she started to stroke it. She intensified the magic that was fondling his prostate. Then she used her magic and sped up time inside his testicle sack, causing his body to create a surplus of semen. His balls inflated and he was on the verge of sexual climax, even though he was still sleeping. He was going to cum at any moment now, and Luna knew just when to time it. She intensified the movement of her magic and just as Pipsqueak was to ejaculate, she used her magic to move his penis downward towards the middle of his diaper. He came at the same moment he released his enema. Now his diaper was filled with his feces in the back, and just like if a filly did it, the middle was wet with his cum.

Luna had a plan for her lover. She knew that if she did this every night for a long enough period of time, his body would be trained to recognize the stimuli and he would cream himself whenever he had a bowel movement in his diaper. He would be trained to be her little foal. Luna smiled as she pulled the pink blanket over Pip. She noticed his face turned bright red as a smile crept along it. Oh, was he in for a surprise when he woke up. In fact, she already knew what she would say to him when he woke up. She was going to break this colt, and make a sissy little filly. Luna then kissed Pipsqueak on the forehead before she headed out of her chamber. She would return once she brought out the moon.
