Supergirl Takes a Backseat

    by: Haro-Haze Author IconMail Icon
Kara fought in near-total darkness to escape from Ruby's iron grip, rolling between her fingers without relying on her super-strength too desperately, realizing that she might become even smaller if she continued to use her powers.

The bug sized Kryptonian woman heard the mysterious sound, sending a shiver down her spine for some reason. She may have only been 12 years old, but fear of the unknown drove Kara into a state of panic as she wondered what Ruby had in store for her.

Fortunately, Kara wouldn't have to wait very long for an answer, as Ruby rolled the tiny Alien between her fingertips, pinching her torso tightly to keep her from moving around and escaping. Being held at chest level, Kara failed to notice that anything had changed. What was Ruby planning?

She looked at Supergirl with pity in her eyes, still finding it hard to believe that her hero and idol was now even weaker than she was. However, Ruby was also excited by the prospect of helping and protecting Supergirl for a change. Supergirl had done so much for the people of National city over the last two years, and now Ruby had a chance to repay her kindness.

"I'm sorry about this Supergirl, but if I'm going to keep you safe and protect you, then I'll have to confine you so you won't fight back. So until I think of a better location for you to spend the rest of the week, I'll be keeping you between my butt cheeks." Ruby muttered, almost inaudibly, but Kara's super-hearing allowed her to make out every horrifying syllable.

Fearing the worst, that Ruby wasn't joking around, Kara looked down at Ruby's waist see that she'd already unbuttoned her jeans. However, they didn't fall or sag, meaning that they were unusually tight on the young girl, a bi-product of her growth, no doubt, but a detail that would make Kara's potential confinement that much worse.

"Ruby, you can't be serious about this!" The shrunken Supergirl yelled, shocked by Ruby's bold choice of location for her as she tried to pry herself free from between the giant girl's monstrous fingertips.

"Please don't be mad, Supergirl I promise it's soft down there. Here, let me show you!" Ruby announced, a little too excited as she rushed Kara down her body, holding her hero at eye level with the back of her jeans. End to end, the structure of Ruby's butt took up nearly her entire field of vision, like two rounded billboards placed next to one another for competing hotels.

The moments that followed were full of Awkwardness and shame for Ruby as she remembered what kind of panties she was wearing. Struggling to shuffle the denim fabric under her buttcheeks with only one hand, Ruby revealed a 50-foot-wide Kryptonian symbol for hope, spread across the back of her underwear, the same symbol Kara wore across her chest.

Shocked, Kara stopped her struggles and looked upon her family's crest with horror. The symbol that stood for hope dwarfed Kara, on the backside of a girl half her age no less, filling her with a sense of despair.

"I'm sorry about this, I had no idea when I put these on this morning I'd be introducing the real Supergirl to my butt!" Ruby announced, looking back at Kara over her shoulder with flushed cheeks.

These words snapped Kara back to the harsh reality she now faced as Ruby slid her hand between her underwear and skin, pulling the fabric away from her skin enough to bring Supergirl in for a closer look. Kara screamed for Ruby to stop, "Please, you don't know what you're doing! I have to leave to stop Nimball!" Kara shouted, beginning her struggles all over again.

Ruby lifted Supergirl over her butt by a few inches, high enough to get a good view of her bare buttcheeks below. Ruby was attempting to put Supergirl at ease, she wasn't trying to tease or belittle Kara in the process, but that's precisely the effect it had on the shrunken Alien woman.

"See, just like I said, nice and SOFT!" Ruby said, rushing Kara into the surface of her right cheek, not holding anything back in the process since she thought Supergirl was indestructible. However, she did need to breathe, which was something Ruby neglected to think of during her little demonstration of how soft and malleable her skin was.

Kara screamed into Ruby's flesh, pounding on the skyscraper-sized girl's buttcheek with both her fists, trying to force her to stop, but it came across as little more than a tickle for Ruby. A sign that Supergirl was ready for more, Ruby decided it was time that she introduced Supergirl to her new temporary living space.

Ruby ironed her hand, she knew Supergirl didn't like one bit of this arrangement, but she was doing it for the tiny Kryptonian's own good. "I'm sorry about this Supergirl, but you've left me no other choice. Until we can bring you back to your normal size, you're no longer a Superhero! You're simply my doll!" Ruby paused, dragging Kara's face and body along the surface of her right butt cheek, towards its twin, "...and good little dolls do as their told!" Ruby announced, shoving Kara between her buttcheeks, trying to make sure she didn't send her too deep into her buttcrack.

Then, once Supergirl was secured between her cheeks, Ruby pulled her hand free of her pants and allowed her panties to seal Kara inside, instinctively clenching her cheeks out of fear that Supergirl might escape otherwise. However, Kara could hardly move, let alone plan her escape as the soft walls of Ruby's butt flesh overpower the shrunken Girl of Steel. Every attempt to fight back was denied by and opposition of equal or stronger resistance.

However, it wasn't long before Ruby began to shake things up, hiking her jeans up to her butt, tosing her cheeks around with Kara inside. She was surprised by how easily she could overpower Supergirl at her current size, believing that she had made the right choice in confining the tiny hero to her butt. If Supergirl was this easily defeated by her, then there's no telling what her enemies could do to Supergirl.

Kara endured the humiliation of being easily contained by the young girls' butt, and continued her struggles as Ruby jumped on her tiptoes, hiking her pants over her butt in one fluid motion. For Supergirl, however, this motion resulted in the equivalent of a cave in, as the soft walls entombed her body, giving her little space to move or breathe.

Ruby stood still for a moment, noticing an end to Kara's constant struggles, feeling relieved when she felt Supergirl twitching between her rear cheeks. She realized that having her hero trapped between her buttcheeks was something she'd have to get used to, realizing that the first step in doing so was just that, the first step with Supergirl between her buttcheeks.

Ruby began walking around the room, shyly strolling as she walked in circles, catching a glimpse of herself in the mirror as she turned. She noticed the distinct lack of change in her butt's appearance. She could feel every move the tiny Alien woman made, but to the rest of the world, her butt looked the same, nobody could've guessed that it was a prison strong enough to conquer the Girl of Steel.

That's when Ruby realized another hurdle she'd have to overcome to get accustomed to having Supergirl so close to her butt, sitting down. She couldn't very well stand for days on end while she waited to see if Supergirl would grow back to normal, but using her hero as a seat cushion went against her kind nature.

That said, she didn't have much choice in the matter since the alternative was allowing Supergirl to roam free, using her powers' until she shrunk to a microscopic level, something Ruby could not allow, as she walked towards her bed. She turned and stood still for a moment, pushing her hips towards her bed to sit down, preparing herself for several possibilities in the process.

"I'm sorry about this Supergirl, but I have to test you out as a seat cushion now," Ruby announced, sending Kara into a panic as she heard Ruby's words. The one alarming her most was Ruby's use of the word 'Test' which most likely meant that using her as a seat cushion was something Ruby planned to do frequently.

Ruby wasn't the least bit surprised by Supergirl's reinvigorated struggles. The tiny superhero responded to the young girl the way she imagined anyone would if she referred to them as her seat cushion. But that was precisely the reason Ruby couldn't hold back any longer. She had given Supergirl the courtesy of heads up and was now mentally prepared to drop herself onto the bed, falling onto the soft surface below with a bounce.

Of course, Ruby's bed was a much more forgiving surface than something like a chair would be to Ruby's butt, pushing her cheeks either in or out, while also allowing them to fall into the bed. Sparring Kara the fate of being entirely entombed by Ruby's butt as the cheeks squeezed her from all sides. It was still much worse than when Ruby was standing, but not as bad as it could've been. Something Ruby had taken into consideration when choosing her bed for her to test sitting on Supergirl.

What Ruby didn't take into consideration was how much she enjoyed sitting on Supergirl, finding the tiny Girl of Steel's struggles to be somewhat comforting.

What happens next?

1. Ruby is focused on getting Supergirl help,she calls Alex and plans to meet her. Unfortunately for Kara, she has to ride her bike to get there.

2. Sam comes in and makes Ruby come down for dinner, forcing Ruby to keep Supergirl a secret during the meal, trying to not react to her movements.

3. Kara is unable to breathe under Ruby's weight and passes out after being sat on for a few minutes, waking up to the face of Ruby, only this time she's sewn into the back of her Supergirl underwear.
