An expansion to the canon

Starfire felt a warm glow in her chest. Her stomach was full and she would have been content to simply lounge on the sofa, perhaps even take a nap. The gentle rays of the sun through the large glass windows of the main living room seemed to agree with that train of thought.

She raised her arms in a stretch and yawned thoroughly.

“Starfire, please, listen.” Raven entreated her. She opened her eyes. What did her friend want now? “He’s done something to you.”

“Me?” She looked over to Mumbo who was whistling innocently. “Friend Mumbo, I thought you said milking friend Raven’s tits would help, but she still seems… not right.”

“Weird. Wonder what it could be then. I have no clue.”

“There’s nothing wrong with me! That madman is what’s wrong.”

Starfire was beginning to seriously worry. Her friend seemed to be under some sort of misconception about her other friend. Was this some sort of Azarathian thing she didn’t understand? Or maybe it was a Raven thing, like that one time they had gone inside her head and her emotions had taken control.

“Best to just humor her for now.” Mumbo offered. “See if it goes away on its own.”

Starfire nodded. Friend Mumbo was usually right about these kinds of things (even if he had been wrong about the need for milking). She had long ago improved on her social skills with respect to interacting with earthlings and the various other aliens she called her friends, but people were just generally a mysterious bunch prone to all kinds of oddities that still perplexed her.

Friend Raven continued talking in generally the same manner, so Starfire did her best to tune it out. She closed her eyes again and laid back on the ever comfortable red plush sofa. Today really was shaping out to be a strange one. First the dimension merging, and now Raven’s odd behavior; what next? Best to just let come what may.

It was in that mild repose that Starfire felt a sort of… burning sensation. A kind of simmering fire in her bottom. Kind of like a bug bite. She shifted around on the sofa, but that didn’t seem to help. She rubbed her skirt-clothed butt into the cushion, but again, such had no effect. Rather the opposite. The sensation only seemed to grow stronger.

What a pain in the grebnacks. She just wanted to have a nice day and now her body was making that impossible. And it wasn’t like there was a Tamaranean doctor on hand to ask about it. Usually that was fine because unlike earthlings, Tamareanean’s didn’t often suffer illness (or injury) due to the ultraviolet conversion system that supplied their powers. But there were exceptions to every rule and apparently her butt was one of them.

She stood up and excused herself. Floating off, she traced the hallways until she reached her room and entered the adjoining bathroom. She turned around so her back was facing the mirror and looked over her shoulder. She raised her skirt and examined the orange skin below.

It looked… normal. Starfire had what she would call a slender form. Her superheroine lifestyle and her alien physique stripped away fat and replaced it with a not-quite muscular, but certainly svelte form. Her modest breasts and butt were part and parcel of that. No blemishes either, which she thanked her mother for daily. Nothing strange on the outside at least.

What could it be?

It was while she was looking in the mirror, after a few minutes of inspection, that she experienced a surge in temperature. Her butt began to glow with a corona of green flames that normally signified a usage of her powers (often to blast a villain). Then, with a sudden burst, her butt expanded. She yelped involuntarily in surprise at the outward motion of her rear. From what was slightly larger than flat, it grew in one jump to what she would call moderately plump. It was enough that she had actual curves! Her hands moved, almost subconsciously, to feel them. They were big enough now that she couldn’t easily fit the whole of them in her hands anymore. She gripped them and a spike of pleasure ran through her. Not only were they larger, they were more sensitive now as well.

Was this some sort of second growth spurt special to Tamaraneans? Not that she wasn’t thankful; she wouldn’t say it out loud, but some of the superheroines that she had known had been more blessed in the feminine than herself, and she had been – only slightly, jealous of their gits.

The glow around her asscheeks subsided. But her questing hands couldn’t stop playing with her ass. It was like, along with the increase in size, a need to play with her butt had been implanted as well. Her eyes were locked on the way her butt deformed and moved under the ministrations of her fingers. It was just so mesmerizing.

“Nggh.” She could feel herself getting closer. It was like there was a cord tied between her ass and her pussy, each pinch or grip strumming that and sending her closer and closer to cumming. And she couldn’t stop. She didn’t want to stop. “Nggggggh.” Her teeth clenched on her bottom lip.

And then in a cascading wave of pure bliss, she came. “Oooooohhhhh.” She came from just playing with her newly expanded ass and nothing else. Her cunt drooled onto the floor. She’d have to clean that up, but for the moment she couldn’t think of anything in particular except for reliving that pleasure in a hazy afterglow.

It was only after an indeterminate amount of time that she was able to think again. And her first thought was how she was going to explain this whole situation to the team. Would they accept her like this? This new Starfire? Of course they would. It was just a small difference after all. Everything would be the same as normal, barring the need for a slightly larger skirt. Her current one only stretched to halfway down her asscheeks, hardly fit for public or private company.

Hmm. In the meantime perhaps it would be best to cover that area. Starfire reached over to the towel rack and confiscated her showering towel for a makeshift skirt. She wrapped and tied it around her waist, and the purple wool did a much better job of hiding her rear, though it couldn’t completely obscure the fact that her posterior protruded that much further than it did before. Oh well. She’d get Cyborg to make a new pair tomorrow (he was always happy to do so, and she enjoyed his craftsmanship).

Right. Nothing to it but to face the music. She puffed her cheeks out and then blew out. Best get to it. She floated out of her room and back to the common room.

“Yo Star, want to join us for a board game? Beast Boy’s picking. ” Cyborg called out to her when he saw her enter the room.

“Yeah!” That sounded like just the thing to distract her from her new circumstances. She floated over to the kitchen table. Beast Boy was shuffling around in the cabinets to the side. The rest of the team was sitting in various states of distraction. Robin was focused on his communicator. Cyborg has a mobile terminal he was plinking away on. Raven was jiggling her tits up and down, letting them plop onto the table before raising them up with hands cupped underneath, while saying how demeaning it was. Terra was blowing bubblegum bubbles lazily. Mumbo was shuffling a deck of cards repeatedly. Normal stuff. Starfire took her own usual seat closest to the wall.

“What’s up with the new duds?” Cyborg asked, nodding to her towel.

“Oh. Nothing.”

“Uh huh.”

“New duds?” Beast Boy, carrying a Justice League themed Monopoly box, echoed in question.

“It’s nothing!” Starfire protested. This however only served to pique his interest.

“Oh, I gotcha. Nothing.” He set the board on the kitchen table. “Brb. Get it set up while I’m gone.” He did a spin and walked out of the room. The team opened the case and started doling out the fake money and choosing their pieces. Starfire for her part chose the dog, which she always thought was cute. She didn’t notice when a pair of green hands reached up from a supine body and pulled down her towel.

“Aha!” Beast Boy cried out. Starfire shrieked and stood up subconsciously in shock, inadvertently revealing her ass to the team members on the side of her. They all exhaled at the sight.

“Star!” Robin was shocked. How could she have tried to hide something like this from them? “What happened to your… your… butt?”

“I… I…” Starfire struggled to put words to her thoughts. “I don’t know. I think it might be some Tamaranean thing.”

Robin nodded. “It’s quite… bigger.”

“I’d say.” Cyborg helpfully added. “It’s practically a booty. Actually, I’d say it is one by the standards of the law. Which means you’re breaking ordinance 1.3.267, Starfire.”

Starfire’s mind blanked for a second trying to recall the specifics of that law. She didn’t want to appear dumb, but legal stuff never held her interest and as such she didn’t really keep it locked tight in her memory banks.

She finally broke and asked Cyborg, “What was that again?”

“Oh, you know, the one where any woman with a butt of classification booty or larger has to get their butt smacked whenever they enter a room by all the occupants of said room.” Cyborg recited as if quoting a piece of text directly, which he probably was.

“Oh.” Starfire remembered now. She had even participated plenty of times enforcing the law on other women with booties. How had she forgotten? Something… something… she shouldn’t break the law, should she? Besides breaking the law, it would be unfair to dish out what she couldn’t take. Though, there was a part of her that wasn’t sure. “Is there a grace period? It’s been a bit since I entered the room.”

“Hmm, we are heroes after all; we’re not above the law.” Robin let a grin slip past his face. “But luckily I know that there’s a grace period for growth spurts as stated in section 567, so we’ve still got a couple minutes to finish the requisite smackings for any built-up entrances.”

Good. Starfire didn’t want to be a criminal; that was for sure. “Got it!” She gave everyone a thumbs up before hiking her skirt up for the second time that day. She then bent over and presented her ass to the rest of the Titans.

“Please, friends, smack my booty.” Starfire entreated her teammates, and they happily obliged. One by one, they queued in a line. Robin was first. He seemed quite eager, and Starfire would be lying if she said she wasn’t happy he was her first in this respect. His green latex gloves glistened and he flexed his fingers.

“Ready?” He asked her, ever the gentleman. She nodded, and he raised his hand high, and then with a sharp motion, it dropped like a rock upon her naked orange butt. She yelped as it connected. It didn’t hurt or even really sting; actually, it felt rather nice, almost like a good minute or two of her previous self-ass-groping condensed into a single action.

“Thank you, friend Robin.” She made sure to beam widely to show her appreciation. He shrugged like it was nothing before making way for the next in line. Beast Boy this time. He had that look on his face when he got a new toy (nowadays that was something music related). So, seeing that, she wasn’t surprised when he shifted form to a dog and gave her behind a swat of his paw. It stung a bit more than Robin’s human hand, but it still wasn’t anything harmful to her tough Tamaranean skin. Though it did have a pleasant aftertaste of pleasure much the same as the previous smacking. She bit her bottom lip again, trying not to show how this was affecting her.

“Next.” Beast Boy called out, wholly unnecessarily, to Cyborg. Cyborg looked miffed about having to be dragged away from his botnets to even bother with this. He quickly gave her a tame smack with one of his metal hands. It felt cool for the brief moment it was in contact, but the burning sensation inside it left was anything but.

And then there was Terra. The girl kept to herself most of the time, but she was still an honored and important part of the team. Had been ever since she joined after those dreadful early years. And plus it was nice to have another girl on the team. Starfire loved Raven for who she was, but having an equal balance and someone else to hang out with on occasion was a nice bonus for Starfire.

The blond walked up and eyed Starfire’s rump like it was some alien thing. Which, Starfire supposed, was technically true to the earthling, but really, Tamaranean and Earthling physiology wasn’t that different. “Go on. Don’t be shy.”

“I wasn’t being shy, idiot.” Terra huffed and raised her hand. It was a pale thing. Terra didn’t get outside much. She spent most of her time training or reading. The callouses on it were a sign of the former. The hand hung there, like it was paralyzed by indecision, but then, with alacrity, it swung down and swatted Starfire’s ass. Starfire’s mind short-circuited for a moment under the **** of pleasure. When she came back, Raven was standing in Terra’s place.

“Starfire, I know he’s making you ignore me. But I’m saying this for my own benefit as much as yours. I’m being made to do this. When we break free, remember that. We’ll get our bodies back to normal too, don’t worry.” Raven was muttering something, but Starfire couldn’t quite understand.

Anyways, Raven raised her left tit with both her hands, and then wielding it as a sort of heavy weight, let it fall on Starfire’s ass. It thudded down with a thunderous clap as the two pieces of flesh collided. Oh. Oh. Ohhhh. That was nice. Starfire hadn’t thought about her friends using something other than their hands, but the larger surface area did provide a more spread kind of pleasure, if a tad less focused.

Raven moved out of the way, and the last team member stepped forward. Mumbo took a bow facing stage left, then another stage right as an unseen audience applauded for him. Raven clapped too. “Thank you, thank you. And now for the grand finale, the great Mumbo himself, here to render to booty what it well deserved.”

“Geez, you don’t have to make a show of everything, you know.” Terra said under her breath. Mumbo seemed to hear that as he adopted an aghast expression.

“But I do, my dear. It’s in the contract.” He unfurled a large scroll hanging in the air in front of him. It was full of tiny text, which he helpfully magnified with a prestidigitated magnifying glass. “Right there you see, ‘Mumbo must make a show of everything.’” He furled the scroll and stuffed it in his jacket. “So without further ado…”

He put his white gloved hand to his mouth and stuck his thumb inside. And then he started inhaling and exhaling large breaths, and with every breath his hand grew in exponential size, until it was at least as big as him. Like the others before him, he raised it up, and then let it descend until its downward arc made it collide with her ass. Unlike the others though, it was a feather light touch. Presumably due to the weightlessness of the magic air with which it was filled.

“I couldn’t stand the thought of harming such a pretty little butt.” He crossed his heart with his other, much smaller hand.

“She can take it.” Robin argued defensively for her, which touched her. She could of course, having just done so.

“Oh I know, but I’m foolish like that I suppose.”

“That’s all of us then. Can we get back to the game?” Cyborg tried to get them on track.

“Sure.” Mumbo nodded. “But just between you and me, I think you might want to study up on the ass laws.” He gave Starfire a nudge in the shoulder. “Right, Tamaranean-girl?”

Starfire had no clue what he was implying, but Mumbo liked to act mysterious even when there was nothing to be mysterious about, so she filed that away and turned about face so she could take her seat again.
