This chapter contains forced orgasim, poop (lots of it), bondage, and pranking.

Luna and Celestia

They were pranking each other again. Luna had pantsed Celestia, so Celestia had been forced to come up with a better prank. And she had. She had cum up with a much better prank.

Luna slowly woke up, her head throbbing.

"Ah, you're finally up," Celestia said. Luna tried to get up, but realized that she couldn't move. Then she realized that she was in a latex suit, shackled to her bed, her legs spread wide open, like a majestic eagle. She also had a gag in her mouth. Her tummy gurgled. "Your probably wondering what's going to happen to you." Celestia was grinning, and had something behind her back. "Well, for one thing, you're going to feel extreme pleasure. For another thing, you're probably going to feel pretty gross. While you were sleeping, I put some stuff in your mouth to make sure you wouldn't wake up. I also put in some laxatives." Luna's eyes widened in fear. "Now, don't worry, it shouldn't last too long." Celestia's grin widened. "But my other gift to you will." Luna tried to respond, but the gag rendered what she said unintelligible.

She was actually getting a little aroused. Getting used like some kind of plaything for another's enjoyment was a small kink she had. Her tummy gurgled, and Celestia snickered. "Well, sounds like the laxative is almost kicking in. I'd better give you the last gift I have before it does kick in." Celestia approached the bed and pulled out a blindfold. She wrapped it around Luna's head, tying it securely so she couldn't see, and pulled out what she had been hiding behind her back. It was a rather large vibrator, almost a foot in length, and pretty wide. She unzipped the pocket that was covering Luna's rarely used, shaved, rather wet looking neathers, flipped the switch, and stuck it in. Instantly, Luna started to moan. Celestia zipped the pocket back up and left the room, closing the door behind her.

Luna had never been penetrated this deeply. It felt pretty good, though the girth was a little wider than she was used to. Her tummy gurgled again, much louder this time, and she felt her stomach churn. Luna wasn't very excited about that. While she did like feeling used and dirty after sex, she didn't want to be that kind of dirty.

Her tummy gurgled again, and she let out a long, wet fart. She moaned, both in pleasure and in embarrassment. It smelled rancid. She was glad that no one was around to see her like this. As she released another fart, she could feel her tummy gurgle more and more intensely. Finally, she stopped farting. Instead, the farts were replaced by a strong, yet small stream of poop. She groaned, more out of disgust than pleasure.

However, this was a little hot. Her cheeks were soon covered by her poop, and it was trailing towards her back and down her legs. Luna hoped that it would end before the suit was full. As the vibrator continued to vibrate, Luna could feel her first orgasim approaching. She let out a long moan of pleasure as her thighs exploded with pleasure, her juices splattering against the suit and her legs, which were already covered in poop. Luna rather liked this, having the poop trail down her lags and up her back. It made her spine shiver with excitement.

Celestia had indeed set up a camera to observe Luna. But it wasn't for Celestia's pleasure. Celestia had set it up to make sure Luna wasn't going to overload. The laxative that Celestia had borrowed was a special brand she had gotten from Equestria. Same with the suit. It had been designed to fill up like a ballon. Though Celestia was going to use it for her own pleasure later. She heard Luna moan, though she didn't know weather it was out of pleasure or out of disgust. Celestia smiled and thought of something else she could do.

Luna's suit was filling up. Her stomach would not stop making poop, and the level had raised noticeably. It was covering her legs, and her hair was getting soaked in it. Luna seriously hoped that it wouldn't get to the rest of her head. But then she heard something. The door opened and closed. Luna moaned questioningly.

"Hello, Luna," Celestia purred. "Are you having a good time?" Luna tried to respond, but couldn't the gag muffled everything. "I'll take that as a yes." Luna heard Celestia approaching, and then felt the zipper above her right nipple moving, and fresh air rushed across it. Her perky, erect dark blue nipple was on full display for Celestia, now.

"What are you doing?" Luna tried to ask. Celestia, of course, didn't answer. Instead, the response that Luna got was something soft and wet brush against her nipple. Luna shuddered as what she assumed what Celestia's tongue wrapped itself around her nipple and covered it in saliva. Luna was moaning and moaning. She was about to cum again. As Celestia's tongue started to flick Luna's nipple, Luna let out a scream of pleasure as her thighs exploded, her cum running down her legs, mixing with the poop. Celestia removed her tongue and smiled, though Luna couldn't see it.

"Oh, what a naughty girl," Celestia said. "You actually like this, don't you?" Luna managed to nod just a little bit. Celestia smiled. "Good, then." Celestia picked up the nozzle of a conveniently close by vacuum cleaner. Luna could hear Celestia's movements, but didn't know what was happening. That made her nervous, but also excited.

"What are you doing?" Luna tried to ask. Celestia didn't answer. Luna had to wait, and when she felt something tube-like cover her areole and nipple, she frowned. What is thi-OH! AH, YES! The vacuum started to suck. Luna was introduced into a world of pleasure that she had never experienced before, and started to moan louder and louder. It was going to be hard to get Celestia back for this. She felt another oragasim approaching, and she worried slightly. Another one so soon? As she climaxed, she lout out a long single moan as her juices joined the seemingly endless stream of poop. Celestia giggled.

"You must be having a really good time in there," she said, placing her hand on Luna's face. Luna started to struggle against her bonds, trying to get out. Even though she was having some of the best orgasims of her life, she didn't quite want to be in her latex prison. The poop sloshed around, covering places it previously hadn't. The poop was reaching a worrying hight. Celestia playfully gasped.

"Oh, wow," she said seductivly. "I didn't know you had to use the bathroom that much. What a naughty girl." Luna was strangely turned on by the name calling.

"Let me out!" Luna tried to say.

"Oh, trying to talk back, now, are we?" Celestia said. "Naughty girls get punished, you know." Luna made a muffled sound of confusion. "You'll be an extremely dirty girl by the time I'm done with you." Luna moaned out, trying to say something, but Celestia had turned around and exited the room, closing the door behind her.

"NOOO!" Luna moaned out, trying to escape her bonds again. The poop was sloshing around wildly, covering her belly and entering her belly button as a small pool. Luna moaned out again. Her tummy was no where near empty! All this coming and poop was making it warmer than Luna would've liked, but Luna wasn't paying that much mind as her climax went over the top again, Luna's scream of pleasure muffled by the gag.

Celestia was relaxing in the living room, looking through a cookbook, wondering what kind of a cake she should make for Luna, after Celestia let her go.

Either way, I'm still going to need to help her clean up, Celestia thought with a snicker. I'm glad that I put that plastic covering over her bed. Celestia flipped a page and smiled. She had chosen a cake.

Almost an hour, Celestia was done. She had finished her cake, and was about to release Luna. Celestia had taken the vacuum off of Luna's nipple a while ago, and had used it to suck up as much of the poop that she could reach. As Celestia untied the shackles and removed the blindfold, Luna sat up and glared at her. the stench of poop was incredibly strong. Luna was removing her gag, undoing the bonds keeping it in her mouth. Finally, she got it out.

"Was the laxative really necessary?" Luna asked, her mouth brown at the edges, and curled into a frown. "And what was with that laxative anyway? Why was I pooping for the whole time?" Celestia giggled.

"Oh, the laxative was from Equestria," she said. "No you should go take a shower, ok? You've still got poop in your suit, right?" Luna nodded, her eyes never leaving Celestia.

"Oh, it's worse than that," she said. "I'm still pooping! I will get my revenge!" She ended her sentence with a maniacal laugh.
