DEAR LITTLE SISTER

In one of Titan Towers many rooms, sat a lonely girl. Well, calling Starfire a girl wouldn't exactly be right. She was a Tamaranean, a particular species of aliens that resembled humans in most aspects. Though her current situation was quite the peculiar exemption to that rule. Starfire was going throught a particular phase of her life. Every once in a while, in the last few days, a new mutation would appear on her body. Be it a horn protruding from her forehead or a bunch of hair growing on her feet, she was slowing getting uglier and uglier. For this reason, she has stayed behind as her friends had gone out to rescue the city. Starfire was part of a group called the Teen Titans and she helped them keep the city safe. Because of this she felt even worse about her situation. She had to stay in the tower or else her friends would send her away because she was an horrible monster, that was what she thought. With this idea in mind, Starfire remained locked in her room until the Titans came back from the mission. Or at least this was her plan, until someone knocked at her door.

"Who's there?" asked Starfire, covered in her blanket.

"Who? It’s me silly, Blackfire!"

"Sister! It has been so long! But I can't see you now, I don’t feel very good"

"What? That's nonsense! Don't worry, your big sister is here to help..."

Blackfire entered Starfire's room and was at first confused to see her little sister all covered in a blanket. She quickly took it away from Starfire and saw at once all the weird mutations on her little sister's body.

"Now you see, I'm a monster! I don't know what to do!" said Starfire while crying.

"Oh don't worry, I'm here now, everything is going to be ok. But first, where are the friends that you told me so much about?"

"Sniff, they're out for a mission. I hope for some days, until I go back to being normal."

"Perfect!" thought Blackfire with a grin on her face.

"Dear little sister, I fear it usually takes more than just a couple of days for the transformation to be complete." "T-transformation? But when you transformed you only turned purple!"

"It is different for every Tamaranean, but don't worry, there's a way to speed up the process, though it is odd and difficult."

"R-really? Please sister, do tell me! I want to be normal before my friends come back!"

"Ok ok, I'll tell you. Thought it’s strange our parents never told you. Maybe they were waiting for the transformation to began?"

"No, they haven’t. So, what I have to do?"

“Ok... Basically, you’re transforming because your powers are out of control, is that clear?”

“Mhm, yes?”

“Then, If you obtain full control over your powers, you can control the transformation and you will go back to being normal.”

“Oh, now I see… but then how can I control my powers?”

“That’s not too hard, we have to make you weak enough so that controlling them will be a piece of cake. And the method I know will let us do that in less than a couple of days.”

“Great sister! Don’t make me wait, what is it?”

“I’ll tell you I’ll tell you…”

Starfire nodded excited, waiting for the solution.

“I will have to absorb your powers in the next few days, and, in order to do that...”

“Yes?”

“… Well, in order to do that, I have to… eat you. Eat you whole and keep you inside my stomach, until the transformation stops.” There was a long pause between the two sisters. For Starfire, what she thought was her only hope to get back to normal was now an horrifying experience. She couldn’t believe that her sister suggested something so crazy!

“A-are you sure, dear sister, that there’s no other way?”

“I fear not. I had to do the same thing for my transformation. I never told you before because it kinda… embarrassed me. But is the only way for you to quickly get back to normal and stop looking like some kind of monster.”

The last word really scared Starfire, just as Blackfire hoped. The little Tamaranean was truly scared that her friends wouldn’t accept her like this and such an horrifying proposal suddenly seemed like the only solution to her fears.

“I... I’ll...”

“Yes sister?” asked Blackfire, while slightly covering the grin on her face with her hand.

“I’ll do it. If it’s the only way to get back to normal before my friends come back then I have no choice. But if anything goes wrong I want you to get me out immediately, sister.”

“Oh, I will. You can always trust me, I’m your sister afterall.”

Blackfire then went over Starfire’s bed and hold her hands, gently.

“Here, I’ll guide you throught the process little sister. It’s not as scary as it seems, just keep going once you’re in and it will be over soon.”

Blackfire closed her eyes and opened her mouth, as wide as she could. Starfire stared at it in awe. It seemed strange to her that her sister could swallow her whole, but now she had no doubts about it.

Starfire hesitated in the beginning, but this was necessary if she wanted to be normal as soon as possible. Besides, Blackfire was her sister, she knew what she was doing.

With new resolve, Starfire started by putting her hands in Blackfire’s mouth and was startled as her sister moaned in delight of the upcoming meal. Then, her hands were inside and soon her arms followed. “O-ok sister – Starfire said reluctantly – I’ll go further...” And so the little Tamaranean kept going, Blackfire’s lips quickly wrapped around her arms, until both sister’s nose bumped into each other.

Blackfire opened her eyes, she had been likely lost in her thoughts until that moment. She watched Starfire: it was clear that her little sister was still scared just by looking at her face. She gave her a wink to calm her down before she opened her mouth even wider. Starfire understood what she had to do and proceeded to move her head inside Blackfire’s mouth.

As she dived in, she felt the virbant fleshy walls that tightly wrapped around her head. The wet and warm sensation that she was feeling was strange to her at first but she got used to it eventually. In the dark depths of Blackfire’s throat there was no way for Starfire to see but she could guess what was going on. Her sister’s lips had just moved past her shoulders and now she was getting to her…

“Hey! - yelled Starfire - careful with those!”

Blackfire stopped for a second: she didn’t listen to Starfire but she wanted to fully savour this part of her meal, her sister’s soft and sweet breasts. She moaned in delight as both orbs of flesh plopped into her mouth. With a resounding “GULP” they were soon sent down, clearly visible as two big comical bulges inside her throat. She kept going, soon her lips got past her sister’s waist and eventually only Starfire’s legs were flailing outside her mouth.

At this point all that was left for Blackfire was to tilt her head back and to let gravity do the work. She slurped her sister’s legs like a big pair of noodles and when she reached her feet she tickled her just to tease her a little more. And finally, after one big and resounding “GUUULLLPPP”, she sent what remained of Starfire to her awaiting stomach.

“Ahhhhh – Blackfire sighed in relief – See sister? That wasn’t so bad and it didn’t take too long.”

Starfire was now completely inside Blackfire’s stomach. It was cramped and warm but after she settled in a better position she didn’t mind too much.

“Y-yes, I’m alright, thank you sister.”

“No problem. It will be over in a couple of days.”

Now full and satisfied, Blackfire leaned over her bloated belly and licked her lips, still full of Starfire’s sweet flavour. She happily watched as her belly grumbled and sloshed with her little sister inside, all had gone according to her plan.

[...]

The next day, the little Tamaranean slowly woke up in her new fleshy home. She didn’t know that the Teen Titans hadn’t returned yet, just as she had hoped. She was startled as she was moved from side to side, as Blackfire woke up as well.

“G-good morning dear sister – said Starfire – Have you slept well?”

“I sure did little sister, I had a great meal after all.” replied Blackfire while patting her stomach.

“S-sure...”

“Ahahah, don’t worry, I’m just teasing ya. It’s time for breakfast!”

Blackfire propped herself up from the bed, althought with more effort than she had anticipated thanks to her huge belly. She headed for the kitchen, her sloshing stomach swayed back and forth all the way. She arrived at the fridge and saw that there was a full carton of milk. She grabbed it without second thoughts and chugged it down. The refreshing taste that filled her mouth was heavenly, althought for Starfire it was quite the cold shower.

“H-hey sister! - yelled Starfire while shivering – B-be careful, please.”

“Oh I’m sorry. Don’t worry, they say milk does wonders to your skin, ahahah.”

“I guess so...”

After Blackfire drank all the milk, she jumped on the couch in the living room, which made her belly wobble left and right, much to Starfire’s dismay. She then took a controller and began to play some videogames.

“Sister please be more careful! It’s quite cramped in here...” asked Starfire as politely as possible.

“Shhh, quiet in there, you almost got me killed!” replied Blackfire, clearly focused on the game.

“Oh, I’m sorry sister, didn’t mean to...”

“I said quiet!” yelled Blackfire with a grin on her face. […]

Almost a week has passed since Starfire was swallowed down by her older sister. At this point, she had no power left, but just as Blackfire said, the mutations had slowly dissapeared, just as she had hoped. However, if that were the case, why she was still inside her sister’s stomach? shouldn’t her sister be letting her out by now?

Blackfire was watching a film in the living’s room, with a bowl full of pop corn. As she ate the salty treats one after the other, Starfire was getting more and more annoyed.

“Dear sister – asked Starfire firmly, althought it was easy to tell that she had gotten weak just by hearing her talking – shouldn’t I get out now that I’m back to normal?”

“It’s not that easy, little sister. We must be sure that I completely absorb your powers, or the transformation may come back again in full force. Just UUUUUURRRRRPPP hang in there.”

The acidric stench of Blackfire’s belch wasn’t the nicest thing for Starfire to smell. And after that she noticed that the gastric juices were beginning to rise, something that didn’t happen in the previous days.

“S-sister – asked Starfire, worried – are you sure everything is alright?”

“Oh sure, everything’s going according to plan, dear little sister...”

[…]

The situation just got worse the next day for the little Tamaranean. She was now submerged in the gastric juices and she felt more cramped than before. She began to realize that she had been fine inside Blackfire’s stomach until that moment because of her powers.

Meanwhile, Blackfire was feeling incredible! The power boost that Starfire gave to her was a pleasant surprise. To make the most out of it, she went to the training room and began to work off some of the extra pounds that she was gaining. Her enormous gut was a bit in the way, it sloshed loudly each time she did one of her special moves but she managed.

After an intense session of exercises, Blackfire stopped for a moment. She played around with her flabby, soft tummy as she cleaned the sweat on her front with a towel. It was much warmer and smoother than the previous days. She could clearly hear gurgling noises coming out of it. But she was shocked to suddenly hear her little sister talking to her.

“S-sister – whispered Starfire, with the little strenght that she had left – you planned to get rid of me from the start, didn’t you? But why?”

A wide grin appeared on Blackfire’s face as she jostled her stomach.

“You finally figured it out, dear little sister! Yes, I never meant to let you out.”

As the truth was finally revealed, Starfire was filled with rage and unleashed a green blast with all the power that she had left. Unfortunately for her, most of her powers had been absorbed by her older sister. What was, in her mind, a powerful blast of energy ended up being a tiny explosion that barely jostled the stomach containing her.

“UUUUUOOOORRRRPPPPP”

With a huge belch, Blackfire released trails of green energy from her mouth, the last pityful attempt of Starfire to escape.

“At first, I wasn't planning to eat you - explained Blackfire – but once I saw just how desperate you were, I knew I could make you do anything I wanted. It made it so much easier, it was great to trick you right into my gut and as a bonus you gave me an extra boost in power, which is always nice. I just hope I’ll get a nice boost in looks too once I’ve finished with you.”

“B-but why do this to me? We are sisters...”

“Oh sure we are, but I couldn’t care less. Some idiots wants to catch me because I took a bunch of stuff from them and if I take your place on this planet they will never found me.”

“That’s absurd! That can’t be it!”

“Well, you’re quite perceptive little sister. That wasn’t the only reason I came here. You took what was always mine, the right to be queen of Tamaran. Our parents even sent me into exile when I fought them for the right to the throne. Once I knew that you were here on Earth I had to take everything from you, like you did to me. Next I will take your place with the Teen Titans.”

“N-no, you can’t… you monster!” “Oh but I will. I already know everything that I need, you told me everything about them!”

Blackfire laughed maniacally as she caressed her gurgling belly

“I really liked to talk with you one last time, little sister. But I think the time has come to sleep you off, for good. All this exercise has sure made me sleepy...”

Exausted, Blackfire made her way to Starfire’s room and jumped onto the bed. She sunk with her face into the pillow, while her soft belly got squashed under her body, much to Starfire’s dismay.

“Please sister – pleaded Starfire, for the last time – let me out.”

Unfortunately for her, Blackfire had already fallen asleep.

[…]

Some days had passed since then and the rest of the Teen Titans had returned from their mission. All of them where shocked when they saw Starfire’s new look. She didn’t seem sick anymore but she had a modest pot belly and her breast and bottom were also fatter than before.

“Hey Starfire, you look kinda… chubby.” Beast Boy said reluctantly.

“Beast Boy, that’s no way to talk to a lady” Cyborg yelled in shock.

“Nope, he’s right.” calmly added Raven.

“C’mon guys, the important thing is that Starfire is ok.” concluded Robin.

“Thanks, I’m so happy you’re back, my dear friends!” happily exclaimed Blackfire. Colouring her hair red was enough to look like Starfire, even the Teen Titans couldn’t tell the difference. For the time being she just had to act like her sister.

“Now that you’re all back, what do you think if we go out on a party?”

“Yeah, that sounds great!” all exclaimed, except for Raven, who didn’t looked quite conviced. “I guess so...” replied Raven, while looking suspiciously at Blackfire.

As the Titans left the tower, Blackfire remained behind a moment, gazing at the back of Raven as she caressed her pot belly.

“Guess what little sister? I think I found out who will be joining you next…”
