Dragon Booty 3

As Spike got off the train, he was surprised to find Twilight was waiting there for him. "Hi Spike! Welcome home!" Something was strange here.

"Uh... hey Twilight, you don't usually come to meet me at the station, what's the occasion?"

"No occasion" said Twilight "I just thought it would be nice for me to come and meet you" Spike was confused, Twilight wasn't usually this... nice, on top of that confusion also came worry, because if someone who was usually not very nice suddenly started acted nice it could only mean one of two things. One, that something very good was about to happen or two, something very very bad was about to happen. Spike was scared either way.

"Come along" said Twilight "Luna will be raising the moon in a few hours, we better get back home yeah?" Twilight turned around and began walking, when she was certain Spike was following close behind, she smirked to herself and added a deliberate and specific exaggerated motion to her walk that made her hips sway and her butt jiggle, not to mention flashing her tight asshole for all but half a second. Spike, being quite a fan of large buttocks, noticed this straight away and began to sweat. He didn't know that Twilight was doing it deliberately to try and rile him up, all he knew was that in front of him was a nice round ass that he had spent many a night fantasizing about.

Come to think of it, Spike had noticed that ever since fucking Luna and Celestia, his dreams about the derriere had lessened and he felt a lot more relaxed in his day to day life, perhaps Luna was being serious and wasn't just a horny princess after all. They reached the door of the castle and went inside, the inside was surprisingly warm, Spike could feel his energy levels rising already. Twilight had raised the temperature inside the castle for that specific purpose, Twilight was determined to get get Spike in her ass the next day and wanted to do everything in her power to make sure he would be up for it.

"Spike, would you mind coming to the library with me? I was thinking of reorganizing some books and I want your opinion, that is if you're not too tired". Since when did Twilight ask for stuff like that? She never asked for anything, she always told. Then again, Spike wasn't particularly doing anything at the moment, so he didn't see any reason why he shouldn't help out, at least she had the courtesy to ask rather than tell.

"Yeah why not, I'm not really busy with anything at the moment, don't you usually do stuff in the library by yourself though?"

Twilight giggled and said "Well yes Spike, but there's a reason for that, a rather embarrassing reason. However there isn't really any way of avoiding it, so I'll just have to hope you don't laugh at me" Spike had no idea what she was talking about until he saw the doorway to the library. This had to be some kind of cruel prank. The doorway wasn't very narrow, but narrow enough that any princess would struggle squeezing their fat rears past it, Twilight included. What the fuck was going on?

Twilight didn't waste any time and started to walk through, as Spike had predicted and as Twilight knew, she had to stop walking when her enormous ass struggled to squeeze through the tight space that most other mares would have considered not to be a problem. Most other mares weren't princesses with well endowed backsides. "Ugh, her in lies the problem, this happens every time. Is my butt really that big Spike?"

Uh oh, Spike had to answer her question in a way that didn't make it sound like he had fapped to her ass regularly ever since her transformation from unicorn to alicorn had given her some extra junk in the trunk. "Um... well, I've never really noticed the size of it, but it certainly looks like you're having trouble there... maybe the doorway is just that narrow?"

Twilight smiled, Spike was such a fucking pussy. "Well the others seem to walk through here just fine" said Twilight "Anyway, I would teleport but I'm just really tired, I don't suppose you'd mind giving me a push would you?" There was no way she could be serious, this had to be a joke. When Twilight just stood there patiently, Spike realized that she meant it.

"Um... OK" said Spike, as he nervously approached that perfect purple ass with his arms forward, ready to push her through the door. He placed his claws on her big booty and began to push, Wow, she was properly stuck in this doorway, had it always been this narrow or had Twilight somehow gotten even bigger?

"Come on Spike" said Twilight "Put your back into it, otherwise I'll never get into the library!"
Well, there was only one option now, using all of his strength he pushed with his arms, shoulders and the side of his face, almost his whole upper body feeling the warmth of her thick butt. Suddenly she squeezed through the doorway, leaving Spike to almost fall flat on his face.

"There we are" said Twilight, now come on, the sooner we start the sooner we finish..."

As time progressed, Spike was teased more and more, there were several occasions where she had to bend over for some reason, or she would accidentally brush up against him, all little things that had left him struggling desperately to hide his erection.
