Twilight knew she was walking a little odd and she looked back as she took a few more steps. "Gel! How much of you is inside me?" She lit her horn and blinked, suddenly depositing both of them in her usual guest room.

The changeling around her gripped a little tighter, making her struggle to take each step. "More than usual. We have some things to talk about but, before or after I make you get so horny you forget your own name?"

The mare froze in place, images of herself trapped in a pod, of her body being ravaged by the changeling, they all vied for her attention as she found herself just nodding.

"That isn't an answer, dear princess." Gel squeezed more and Twilight would have collapsed under her own weight were he not holding her up. "Tell me, Princess Twilight Sparkle. Tell me what you want me to do to you?"

Her thoughts raced, a pod would be nice but she was sure he didn't have one at hoof. "Uh, I want you to fill me, front and back, you have enough now… I want to be full but free to squirm and struggle, but don't let me stand or use my hooves." She blushed, even though she was sure Gel had read both her secret diaries, she blushed that there was another pony who knew her secrets. The fact the stallion held the knowledge only proved to excite her more.

"Is my filly sure that she will be suitably aroused by this?" Gel flexed inside her, using a new trick he had been practicing. With a series of contractions and forming a little tube, the changeling started to inflate that ball of himself in her womb, growing Twilight's belly bigger and bigger.

"Please… all of me…" Twilight was fighting herself, it felt very uncomfortable being as big as he was making her, but even that only served to enhance the pleasure from her fantasy made real.

"Since you ask so nicely." Gel withdrew his mass from her womb, pouring himself out and around her, he made sure to inflate within so that the mare shouldn't feel any change in size. Moving their legs, Gel walked over to the bed and climbed carefully up onto it. "This is where your prison of pleasure will be." He whispered the words as he pushed into her throat. None of it felt as sexual, for him at least, as the dream did. He wondered briefly just how he had felt all of… that. But there was a job ahead.

Twilight tried to respond but the tubes sinking down her windpipe made her mouth work and not a single word came, fortunately as Gel sank in she worked her throat and mouth muscles, her body resisting the intrusion into a place that wasn't meant to be this full. Her body was released of Gel's restraining hold and she found herself suddenly feeling like she was choking. She felt her body spasm and buck with no urging from her, writhing as her gag reflex fought a losing battle. Gel was inside her and there was not a thing Twilight Sparkle, Princess of Magic and Friendship, could do.

Gel let the mare struggle and move, he was sure she would be trying to talk and plead, but he knew from her diary and the waves of hot pleasure feeding him that this was exactly what she wanted. His questing tendril found and opened the last valve to breach the mare's belly and, inside, he started to swell out, using his new trick to make his lover feel very very full. "Hungry, Twilight? Maybe another hayburger?" He added a little more to the size in her belly. "Just nod my filly, nod and you can eat another."

Twilight was panting out of those tubes leading to her nose. She was so full with just her womb and belly inflated. A spasm of pleasure ran through her. She nodded. Twilight couldn't hold back, she bucked and whimpered, her climax rushing in as her belly reached a point where she was sure she would burst from pressure alone. Her muscles contracted tightly around Gel, again and again, her throat milked at him just as much as her breeding passage did. Then she felt a questing poke at her, recently at least, well used tail-hole.

"That is two places, should we go for three? I think a filly asked for three." Gel spoke directly into her ears as he started to push in, his own form the perfect lubricant for the mass that worked and pushed, claiming Twilight's last remaining passage. Her muscles tried to fight it, but there was nothing she could do to stop him, her body was too worked up for any magic and physically, the changeling held all the cards.

Gel was running low on body-mass, his recent growth aside, he wouldn't mind being a bit bigger, if only for these situations. Lacking any more mass, instead he started to inflate the mare's colon, spreading her rump out so her back-end would be pudgy indeed.

The aching and basic need to void herself consumed Twilight, but no matter how she worked her muscles, how hard she bore down with her body, she couldn't shift Gel from her body. She was in heaven, her own little version of it. She sat still for a moment, just bathing in the sensations of being so full.

"Twilight." The word sounded like the stallion was singing it. "Twilight? You still with me?" Twilight nodded her head, she was near to climax again, just from laying there. "Twilight I found another place." This actually stirred the brutally intelligent mare to think, to engage the mind that had been set adrift. "Would you like me to fill it? I promise I will be gentle." She nodded, she nodded so much she lost her control and her body pushed her to her peak again.

Gel felt her tremble and buck, judging her release to be the perfect time. Carefully, making a part of himself very, very thin, he poked at a little orifice he knew was there.

Her legs kicked and Twilight tried to get up, she was still struggling against her climax, though, and all she could do was writhe as Gel started to work into her urethra. That was certainly not a place they had agreed on! But… but it felt good. Everything felt good. Twilight slumped to her bloated side again as she felt that new tendril, feeling so very huge, slither and work deeper and deeper. Her legs moved and she tried to get up.

Twilight's legs slipped and she fell back to the bed. Something was wrong and she pressed one hoof to the floor beside her and felt the tip glide with not a jot of friction. The tendril found a new sphincter inside her and, with a little effort, squirmed at it and opened it up.

"Come on Twilight, we need to go to the bathroom, I can't fill you there if you are already full. Naughty mare, in future you will want to empty your bladder before our games." Gel turned Twilight's head so that she saw where the bathroom was. Ten feet away. Twilight worked herself to the edge of the bed by repeatedly squirming and flopping and set to try and tumble off to the floor. Instinct tried to force her wings to spread but she felt the tight grip that pinned them to her back.

Gel inflated Twi's rear a little more, judging she was up to the extra size and figuring it would be more incentive.

Twilight tried to moan, to cry out, to demand him to stop and let her free. She didn't want to be free, but there was a limit to things and her bladder… that was a limit for her. So why was she crawling to the bathroom on her belly? Why was she trying so hard to get in there, to empty herself so he could fill the space? Her brain was confused but her body wasn't. Swimming, Twilight made poor time, particularly when she climaxed hard again, but at last she was at the bathroom door.

Gel looked at the handle, thankfully the mare wouldn't have to deal with that, it was slightly ajar. He felt the determination in Twilight with every inch of ground she gained and, soon, was at the tiled device that served ponies. "Good little filly, now get yourself over the drain now, time to go." Gel was astounded at the sheer willpower. He felt Twilight climax again as he called her a filly, but she kept moving, kept squirming and getting her back legs over the middle of the drain.

The relief was quick. Gel simply made the tiny shape in Twilight's urethra hollow and, even as Twilight realized she had not a bit of control over the action, she was given relief. "There there, all of it will be gone and you know what I am going to do then, Twi?" Twilight squirmed, she didn't need to be in the embarrassing room anymore. "This."

Twilight Sparkle felt as her bladder started to not just signal that she needed relief again, but it told her in no uncertain terms that she was very full and needed to go again, right now! She bucked and squirmed, kicking and fighting the feeling within her. She knew she didn't need to go, but she also knew that Gel wouldn't let up. Her back hoof connected with something solid and she heard a door slam shut.

"Oh dear, looks like this is your new home for a while, princess." Gel's mocking words had the desired effect and with a hot blush, Twilight Sparkle came hard. Her writhing motions were random, her body fighting to be able to resist the intrusions that had her mind so very aroused. Twilight's bladder tried to empty, her muscles squeezed, her sphincters opened up, everything a mare needed to do to relieve herself was done but there was no relief in sight. And worse, that confirmation, that very fact, pushed her to another orgasm.

Twilight lay on her side, on the bed. Behind her Gel was pressed in against her back, the stallion nibbling lightly at her neck. She was being spooned by a very naughty pony. "So, out of ten?" Gel stopped nibbling long enough to ask her the question.

She thought on it. Being so full, bigger than a pregnant mare and in more than one place… "Fantastic and you know it… eleven."

Gel would purr if he was a cat. "So, able to think enough now?"

Twilight nodded, feeling the back of her neck press in against his throat.

"Good. As you felt, I am a bit bigger. Princesses Celestia and Luna asked me to… drain Chrysalis a bit, so they could have her out of her pod and talk to her safely. This seems to be a consequence." Gel reached a hoof around and between Twilight's front legs, rubbing slowly. "Luna helped me… that is why she gave us that dream, to pay me back for my work…" Gel was blushing, not that Twilight noticed.

"That dream was fun do… do pods really do that?" Twilight's own hoof betrayed her, straying down to rub her belly and thighs.

"They can be programmed to bring such pleasure. I will get us one for home." Gel nibbled Twilight's neck, he could smell her arousal build again. "But more news before we talk of sinking you into a tentacle-filled pod." This made the smell grow faster. "When Chrysalis came out I… she seemed defeated, mentally. She asked to stay in the pod for a year."

"Uh, so…" Twilight's hoof stopped, Chrysalis seemed to be one of the few things Gel could talk about that would turn her off.

"So, being in a pod, for that length of time… it makes you feel happy, very happy, all the time. You can't stop it and slowly, your own memories are replaced by that feeling. With a year in there she will wake with nothing." Gel just held Twilight to his chest.

"That… why would she want that?" Twilight blinked, her mind working to try and make sense of what she was being told.

"I think after a little time in there to cool down, she hated herself almost as much as we do." Why was Gel crying? He couldn't work out either why or how, but the thought of the proud and dominant queen sacrificing herself seemed like the very opposite of the selfishness she normally showed.

"So until she rises again, what of the changelings?" Twilight wanted the topic to shift and it seemed like a good way to do it.

"They were a little miserable, they were being held on the outskirts of the city." Gel had to press a hoof to her cheek and flow a plug into the mare's mouth to stop Twilight from interrupting him. The smell returned. "I have taken responsibility for them. I couldn't not do it, they needed somepony who could stand, at least a little, against Princess Celestia. I have negotiated their rights." Gel finished and drew back from Twilight's snout, rubbing her formerly puffy cheek in apology.

It was a testament to their strange games that Twilight didn't even consider being gagged while talking with Gel to be odd or remarkable. "They will be allowed in the city?" He nodded behind her. "Good, you weren't the only pony under her spell and I bet there are plenty of good ponies looking for homes."

"Twilight, are you thinking of adopting?" Gel teased the mare, his hoof lowering from her cheek down to her belly, rubbing all the places on the way.

"No! I mean… they couldn't all be bad."

"You are right, they are mostly just ponies. One drone, it seemed, was stationed in Canterlot before the invasion, for quite some time. She was called back by Chrysalis, but left a wife here. They have reunited… adorably." Gel gave a sigh, remembering not just the scene of the pair but their taste. "Oh, another thing that has cropped up with this… mojo, in me. I can taste, sort of, other ponies' emotions."

Twilight snorted. "You could do that already."

"No, I mean all ponies, just being near somepony means I can feel the love, the pleasure… I am trying to work out ways to block it." Gel sounded a little worried to Twilight.

Twilight thought on it. "Do you actually feed from them while it is happening?"

"I… I don't know."

"This means we need to do an experiment." Twilight sounded about as excited as Gel had ever heard her. "Oh this will be awesome." The spike in her feelings puzzled the changeling, but he knew one thing for sure, he would have to work out a way of building this enthusiasm into their games.
