Author's Note

After insanely long wait it's finally here: the last chapter. College plus other commitments made it really hard to create time to finish this. I do hope to create another story in the near future if I get the time and motivation, don't know what that next story will be though.

Anyways, thanks to everyone who's read this, hope you enjoy a quick little finale.

Conclusions

Twilight trotted home in absolute disgrace. The falling rain easily matching her mood. She had just finished up at the magic expo, where she presented the results of her experiment. It seemed to be going well; until they banned her for "unethical practice". However, since Twilight's spells technically hadn't caused any harm and there were no specific rules against what she did they were unable to go any further than that. Even if they could, those in charge decided it would be better to just kick Twilight out and cover the whole thing up to avoid attracting controversy.

Perhaps it was for the better though. She didn't have to worry about it anymore. Although, there was still the nagging issue of what to do about Rainbow Dash now. Twilight had yet to find any spells to reverse the ones she had been using the entire time. So it was likely that Rainbow would just have to lose the weight on her own. "As long as she doesn't find out I'm the reason she got so huge in the first place, I'll be fine."

She entered her library with a sigh of both exhaustion and relief. She was home, the project was done, and now it was time to move on to something else. She soon found Rainbow Dash laying on the new couch that was purchased before Twilight left on her trip. Rainbow had become too large for most normal furniture to handle. A couple broken chairs served to drive that point home. It wasn't hard to see why this was the case; Dash herself was large enough to be a couch. She opened her eyes as Twilight walked in, smiling as she spoke, "Hey, Twi. How was the big trip?"

"It went great,"Twilight responded while putting on a fake smile and biting her lip slightly, "Absolutely perfect."

"That's good to hear,"said Rainbow Dash as she slowly got up from the couch, grunting as she struggled to lift her massive frame. At this point she was probably one of the heaviest mares Twilight had ever seen. Her gigantic, round,bulbous belly stretched so wide that it forced all four of her legs to take a wide stance. It also hung so low that it seemed to be slightly grazing the ground. Rainbow's flank had continued the trend of outpacing her flank. Her rear and hips had grown so large that Twilight could see them bulging out even while being in front of Dash. All together Rainbow Dash was a lovely sight to come home to. It was a shame the experiment was over now, but at-least the results were spectacular.

"Anyways, I'm going to go grab a quick snack," Rainbow Dash broke the silence as she begin slowly hauling herself across the room. Her entire body shook and wobbled with every small step. Twilight became so enthralled that she was caught completely off guard when Rainbow swung her lower body around with surprising speed and force; knocking Twilight into a nearby wall.

Twilight rubbed her head while trying to regain her senses, "Owww, Rainbow! What was that f-", her protest was cut off as she saw Rainbow Dash backing up towards her. Rainbow's titanic, blue flank was beginning to overtake her entire frame of view. Realizing the dilemma, Twilight attempted to use her magic to push Dash away. However, Rainbow was far too heavy and Twilight far too stunned. Soon she found herself being engulfed by thick flesh as Dash slowly laid down on top of her. Rainbow's belly pinned down most of Twilight's body, while Twilight's face was squished directly between two humongous flank cheeks. She reached out her hooves to try and push Rainbow Dash off, but found nothing but more and more soft flesh. There didn't seem to be any end to the rump that was trying to squash her.

"I know about your plans to turn me into Rainblob,"said Rainbow with a bit of snarl. She certainly sounded angry, but there was a hint of mischief as well. She had Twilight right where she wanted her. "You got pretty close, but the experiment's over. Now it's time to reverse all this."

Twilight knew for the sake of getting oxygen it would be best to agree to Rainbow's demands. However, part of her was enjoying this. It felt so amazing to be surrounded by a flank that was so huge and round, and so plush. If only she had a breathing spell to cast on herself she could spend all day burying her face and hooves into the endless expanse of Dash's rear. In the end her desire for air overcame her lust as she tapped on Rainbow's flank in submission.

Rainbow Dash lifted her body up just slightly, giving Twilight enough space to start catching her breath. "Alright...*pant*...you win, Rainbow.."

"Good. So reverse all of this."

Twilight carefully worded her response, "Well, I don't actually know how.."

Rainbow Dash apparently didn't like that answer, "Then you better get ready to take another plunge."

"No, wai-!" Twilight's protest was cut off as she was once again submerged in Rainbow's massive flank cheeks. The two giant oceans of blue flesh overwhelmed her senses and took her breath away in more ways than one.

"I'm not even putting my full weight down" Rainbow Dash said in a mocking tone, "Just imagine if I did though." To emphasize her point, Rainbow put a slight bit of pressure on Twilight. Twilight gasped as she felt the air being pushed out of her. She began to fear she would suffocate like this, but at the last moment Rainbow Dash picked her body up again. "So, I hope you thought hard about what I asked you, because I'm getting kind of tired and you make for a nice bed..."

Twilight composed herself and heavily thought out her answer. "Okay, Rainbow. I'll figure out how to reverse the damage. Just please...let me breathe for awhile."

"Good enough for me," said Rainbow Dash as she gave Twilight a bit of space and turned around.

"There's just one thing, Rainbow,"said Twilight, "How did you find out?"

Rainbow Dash stepped out of the way, revealing a very flustered looking Spike. "I'm real sorry Twilight, but I just had to tell her. When I found out what you were doing...I just..."

Twilight sighed, "No,Spike. It's alright. I deserved this. Rainbow Dash, I'm sorry. I was wrong to use you the way I did. Could you forgive me?"

"Well, we'll see how my new weight loss goes," Dash answered, "If it works out, we're cool. But if I'm still packing on pounds, I'll turn you into Twilight pancake."

The teasing note in Rainbow's voiced made it impossible for Twilight to tell if she was joking about that threat or not. It was a shame Rainbow Dash's beautiful new figure would soon start slimming down, but Twilight at-least would have the pleasure of watching a massive, round belly; and huge,sweat-drenched flanks bouncing and wobbling everywhere during Dash's exercise. Plus, who knows? Perhaps the time would come for a new experiment someday...
