"I can't laugh. Not yet." Spike told himself as his mouth was twitching upwards. He walked casually back towards the library using all his will power not to burst out in happiness at his success. He wasn't planning on anypony currently outside learning about his secret, especially right after he successfully got his prize.
Less then five minutes ago, Spike was able to pull off his diaper "heist" and did so with practically no errors. "I've gotta admit, that was just too simple. I was honestly hoping for a bit more of a challenge. Oh well, I can't complain about an easy win. Spike thought to himself in a cocky manner.
"I never would've believed taking risks like that would be so exhilarating. My heart was pounding at some points and it felt amazing. Heck, it's still pounding." Spike told himself as he got high on his current adrenaline rush.
Spike then forced himself out of his adrenaline high, attempting to return to his logical self. "Focus Spike! That may have worked out well the first time but that may not happen if I take another risk. I have to stay calm and collected. I can't let this win make me feel invincible"
As Spike quietly scolded himself, he reached the library door with all his bags. He then walked inside the dark library, seeing a very much awake owl waiting to greet him.
"Ah Owlicious, I see your as vigilant as ever" Spike told the Owl who looked at Spike with a curious stare.
"Relax. I just needed to pick up more animal food for Fluttershy, which I'll drop off at her house tomorrow." Spike told the Owl as he placed the animal food in the kitchen and filled up his new bottle with milk making sure it was clean first AND making sure he wasn't seen while doing so.
As Spike began to walk to his room with his saddle bag he glanced over his shoulder. "I'm going to be going to bed a bit earlier tonight so please don't interrupt me unless it's important."
The Owl simply made a "hoo" sound which Spike interpreted as "are you felling alright? It's not even 9:00pm." Spike reached the door to the bedroom and replied to the curious owl. "I'm doing alright, just had a long day is all."
Spike walked into the bedroom closing his innocent looking eyes. He then closed the door behind him and opened his eyes slowly which now looked far more piercing and reptilian while also filled with immense pain and desire. Spike then quietly spoke. "In fact, I'm perfect now that I've got what I want.
Spike then takes the diapers and foal supplies out of his saddle bag, opens up all his supplies, and sets his baby bottle filled with milk next to his basket, all while laughing quietly as his eyes began to get misty. "Finally. Finally, I got my diapers. It felt like it took forever but it's finally time. No more worries, no more distractions, no more responsibilities, no more expectations, and for now, No. More. Pain.
Spike then looks carefully at his diapers. He didn't check to see if he got any with tapes or not. To Spikes surprise, the package is half and half. He could've sworn diapers were only sold with or without tapes in a single package, yet the proof was right in front of him.
"It looks like both Celestia's sun and Luna's moon were on my side today." Spike silently told himself with a grin showing off his fangs as they reflected moonlight off of them.
Spike then decided which diaper he'd wear. I guess I'll just put on one of the pull on diapers. If I knew I could get away with wearing a diaper with tapes then I would. If I used a diaper with tapes then I'd have to actually use it for its intended purpose since I'd be wasting the diaper if I didn't, which I'm not sure I can get away with just yet."
Spike then placed the plastic from the foal diaper package on the floor to use as a makeshift changing mat, grabbed the foal powder, and grabbed the diaper, while trying to figure out what he needed to do. "I should be able to do this. "I've helped out with diapering the Cake twins before. The only difference this time is that I am diapering myself. Since I'm using this pull on diaper, I only have to worry about the amount of powder I use in the diaper and rub on the 'diaper area'."
Spike then sat on the "changing mat" and lied back. He then started to tip the foal powder over slightly and shake it. Instantly, the white powder fell on his "diaper area". He then lifted his legs high in the air and applied the powder to his bottom, blushing the entire time as thoughts swam through his mind. "T.. this kinda feels nice. I kinda feel like I'm getting a diaper change. I wonder what it would feel like to have another pony diaper me though. It probably won't ever happen since I don't plan on telling a single soul about this."
Spike's heart was fluttering, his cheeks were tinged red, and his body felt lighter than a cloud. It was kinda embarrassing even with nopony in the room watching but at the same time, it just felt so... right. "Wha... What is this feeling? Is this what it feels like to be truely happy? I mean I've felt happy before, but this feeling... It's on a whole new level!" Spike said to himself as he wholeheartedly embraced this new feeling with a bright, cheery smile and breathed in the sweet foal powder smell.
Spike then sprinkled some powder in the diaper and slid it up his legs while he slipped his tail through the hole in the back. As he did so, he couldn't help but giggle childishly at how thick and comfortable the diaper felt between his legs as he unknowingly bounced on his freashly padded rear causing crinkles and a tiny puff of powder escaped his diaper.
Spike suddenly realized what he was doing and stopped moving all together. The only way to tell that he wasn't a statue was by looking at his reddening face. "Why did I just do that?! Not that it was bad or anything. I mean–" Spike then cut off those questionable thoughts and smiled with his still slightly pink cheeks. "You know what, it doesn't matter. I can't deny that just bouncing with my diaper on was fun and I don't want to deny it either."
After bouncing a few more times on his padded behind, he moved his bed and opened up his "hidey hole". He then proceeded to place his extra diapers and his "changing mat" inside for future use. He also pulled something out, a plushy which looked fairly similar to Rarity. He then closed up the hole and put his bed back in place, all while he was accompanied by crinkles.
"I wonder what drinking from the foal bottle will be like." Spike then grinned cutely and giggled. "I guess there's only one way to find out."
Spike hopped into his basket, pulled the covers up to his neck, grabbed the foal bottle in both claws, and started to suckle. It was a bit hard at first to get the milk out but he soon got a rhythm going as cool milk began to flow gently into his mouth and down into his stomach.
Spikes mind went blank as he closed his eyes and suckled his bottle without a care in the world and with a content, peaceful smile on his face. If anypony had seen him now then they probably would've mistaken him for a baby or at the very least, a toddler. After a few minutes his mind came back to reality as he realized he'd been suckling on air for about thirty seconds. He then slid the bottle out of his mouth creating a small "pop" sound and placed the bottle next to him in his bed.
"Mmm, that seemed to taste better then normal. It also felt really nice. Really relaxing." Spike groggily thought to himself and then yawned.
He then grabbed his Rarity plushy and hugged it tightly, ready to enter dreamland. After a few minutes however, Spike felt he was missing something.
After a few moments of thinking, Spike realized what he was missing.
He grabbed his tail and slid the tip of it inside his mouth and started suckling on it just like a pacifier. His tail filled his mouth perfectly, almost as if it were meant to be there. Now hugging both his tail and his plushy closely with his covers as well as his comfortable diaper keeping Spike warm, he knew now that he was ready for bed.
As Spike was starting to drift off, tears slid down his face. These weren't tears of sadness though. No, these were tears of absolute joy. Spike realized this was the best feeling he could ever remember as he finally felt special and loved. Hopefully he will get to feel like this more often. He can worry about that later though. For now Spike is content with how he feels right now and that's all that matters.
"Nini Wawity" Spike groggily lisped around his tail to his plushy while continuing to suckle his tail as he fell asleep in the safety and security of his comfy diaper like the baby dragon he truly felt like on the inside.
