DON'T READ THIS CHAPTER IF YOU WANNA KEEP THIS PG. It gets a bit explicit.

This goes into some weird territory. Sooooo... Hope you all like it! Please comment because I really don't know if this one was good or not. I'm bad at writing along these lines.


"Yes dad," Alex sighed. Her dad was being a special kind of annoying at the moment. "I'm eating well."

"Don't worry, Jeremiah!" Kara was squished up right next to Alex, happily chewing on some twizzlers. "I'm feeding her!"

"Thanks, Kara!" Jeremiah said, knowing Kara could hear him.

"You're welcome!"

"Alright, alright. We have work to do, gotta go!" Alex was eager to get off the phone. Kara had an exam coming up soon and Alex had to help her through it. World History was particularly hard for Kara to get through because she always got so frustrated with how things happened and why they happened.

"Okay honey, I love you!" Jeremiah said, waiting patiently. Alex groaned, cheeks flushing at the affectionate way Jeremiah spoke to her. She was a grown woman!

"Okay dad, love you, too! Have fun on your business trip!"

"I'll be Peru. And I'm not going yet! I'm going to be back in Midvale probably before I go, so will I see you and Kara there?"

"We'll try!" Alex was barely keeping back a growl of impatience. "Okay, bye! Have fun!"

Kara leaned in, eager to call out her goodbyes, too.

"Bye, Jeremiah!"

"Bye, girls!"

Finally, Jeremiah Danvers hung up the phone. Alex plugged her device in at her nightstand before flopping back on the bed next to Kara.

"Okay, so what's the problem?" Alex asked, looking over the page that Kara was reading. "It's basically memorizing dates and events, right?"

"It's not just memorizing! I have to write an essay on all of this!" Kara waved her hand around at all the textbooks on their bed.

"Who told you to take 'The Effects of Colonization on Turtle Island', 'Intro to the Islamic World', 'The African Diaspora in the Americas, 1492-1804', and 'Intro to Chinese History' with the language of instruction being Chinese." Alex asked bluntly. "Maybe you shouldn't overburden yourself."

"Uh, I believe the correct Earth idiom to use is, 'pot calling the kettle black'. Aren't you working your way through some PhD programs right now?" Kara asked sweetly. "Don't you already have enough credits to graduate but you're still-eep!"

Alex had rolled Kara over and pinned the woman, growling playfully. Kara mock-struggled a bit, but let Alex pin her down, grinning up at her sister.

"I win." Alex replied smugly. Kara pouted a bit before she rolled them over so quickly, Alex wasn't sure how she ended up on the bottom of this little wrestle pile. Alex smirked up at Kara, knowing that the Kryptonian sometimes did like to use her strength and show off a little bit. This was one of the ways she liked to do it.

"Say you give." Kara demanded.

"Never!" Alex said laughingly, putting up a fake struggle while Kara sat on Alex and kept her hands trapped above Alex's head easily. Alex bucked up, grinning. Usually, Kara would make some over-dramatic supervillain speech, but Kara's previously mirthful mien to change to a wide-eyed, deer-in-headlights look. Alex could also feel Kara's grip on her hands suddenly loosen that iron-tight grip, so Alex took the opportunity to wrap her legs around Kara's waist and flip them again.

"Got you!" Alex grinned, sitting on Kara smugly. One second Alex was sitting, knees on either side of Kara's waist, and the next she was thrown off Kara, sent tumbling off the bed.

"Alex! Are you alright?" Kara super-sped to the end of the bed, helping Alex up gently.

"Kara!" Alex rubbed the back of her head, checking to see if there was a lump. "That hurt!"

"I'm sorry," Kara looked genuinely remorseful. "I g-guess I just, I got… never mind."

Alex sighed, reaching up and raking her fingers through Kara's unruly hair.

"It's okay. This has been your first accident in a long while which is really good!" Alex flopped back on the bed and patted the spot next to her. "But enough goofing around, let's continue."

"A-Alright." Kara stuttered, crawling back next to Alex. They continued going through the chapter in the book that Kara was having trouble with, Alex noting briefly that Kara was at least taking this seriously and no longer treating this as just another cuddle fest, though she seemed extra squirmy. The end of their wrestle play-fight had been a little blip in their usual trouble-free existence and Alex didn't think more on it.

But by next week, Alex was noticing something was up. Kara had been acting weird. And Alex just couldn't figure out what the problem was. It was just that, for more than a few days, Kara had not been able to look her in the eye and Kara had also been running off, telling Alex she was going to study at the library instead of at home. Alex had instead bumped into Kara-when she was supposed to be 'at the library'-at a cheap cafe. Kara had immediately slammed her laptop closed when she saw Alex. Good thing they had chosen a really durable laptop for Kara. The real hammer on the head was when Kara didn't roll over to spoon her at night and religiously kept to her side of the bed.

The third night in a row with no rollovers from Kara, had Alex frowning over her breakfast at Kara. Alex had made them pancakes and Kara had been wolfing them down as normal. Except she wouldn't meet Alex's eyes when Alex tried to talk to her. The whole week Kara had been sneaking around and avoiding Alex and Alex was starting to get kind of hurt, as she stabbed at her eggs grumpily.

"Alex?" Kara's voice was tentative. "What's wrong?"

"I don't know. Can you tell me?" Alex replied in Kryptonian. Her snappy response made Kara tense up.

"I don't know what you mean." Kara replied nervously. Alex, not feeling like dealing with this, got a tumbler and poured the rest of her coffee in it.

"Well, I'm going to lessons. Please clean. I'll see you later." Alex was out the door. Alex was annoyed and angry, but things were still good, they were so good right now. Alex was doing really well in school. Her parents were proud of her. Alex didn't know how she even managed it but her profs all backed her one hundred percent and had basically tricked her into applying for several programs… it was… sweet how much they wanted her to succeed and she was trying hard not to disappoint them.

And Kara. Kara was taking her one hundred and one different courses, and doing spectacularly in them. She had finally decided on a double major, History and Philosophy, But sometimes Alex would see Kara flipping through Alex's textbooks with more than passing interest. The questions she asked made Alex realize Kara's knowledge of the subject was greater than maybe even Alex's or her profs.

Having Kara around, just having her there, made things so much brighter. Nothing was insurmountable and nothing was so difficult that Alex couldn't come back from, not when she knew Kara had gone through so much worse. Alex would admit to anyone that Kara was one of the bravest, kindest, and strongest people that she had ever had the privilege of knowing. She might even go out and say that Kara was THE bravest, kindest, and strongest person in the world. Kara just made everything BETTER, for some reason. And Alex always knew that Kara was better than her at everything, even if Kara never saw it that way.

So Alex worked hard, not just for herself, but for Kara, to keep pace with her alien sister, but that required a lot of time on Alex's part. After her little tiff in the morning with Kara, Alex had gone to her class, then to her teaching assistant gig. Alex had her labs after that, THEN some in-office hours, so naturally, Alex had missed dinner. Alex hadn't called Kara back when Kara messaged to ask where Alex was, only sent a terse three-word message saying 'I'll be late'.

Kara had replied, her missive sweetly worried, telling Alex to call her when she was on the way so Kara could heat up food for her. Alex had chosen, obstinately, to not call at all, and not send a message when she was on her way home. Alex was the 'older' one here! She didn't need Kara worrying about her.

But maybe if Alex had called in advance, it would've prevented the highly awkward situation of Alex walking in to see Kara with her pants down to around mid-thigh, sitting down on a towel on the sofa, trying hard to… it seemed like she was trying to pump something up and down in the general vicinity of her groin.

"Ah! Oh god! I'm sorry!" Alex dropped her bag on the floor, frozen to the spot, thankful she had closed the door behind her.

"Alex, don't look!" Kara screeched, her hands over the cylindrical contraption that was… staying put right over Kara's pelvic region.

"Is that… are you…" Alex gaped at the black coloured silicone… sex toy. It was definitely a sex toy. Oh my god, Kara was using a sex toy.

"STOP LOOKING!" Kara screeched, her glasses slipping down her nose. The Kryptonian was so flustered, she seemed torn between getting up and running to the washroom, and trying to curl in on herself to hide the contraption. Or probably, Kara just wanted to curl in on herself and die from embarrassment.

"Kara, please just-just, I'm going to leave and can you just put yourself together and-" Alex fumbled behind her, trying to cover her eyes while trying to find the doorknob.

"No, Alex, I… I need help." Kara sounded distressed enough that Alex lowered the hand covering her eyes to try and look at Kara-only in the face. Nowhere below the neck.

"Kara. What-I'm afraid to ask." Alex kept her hand up, the height and position of her hand helping to cover up Kara's body from view, so Alex could look Kara in the eye without seeing that… thing.

"I'm stuck." Kara said miserably. "I can't get out."

"What." Alex dropped her hand now, stunned. "You're what?"

"Stuck." Kara repeated miserably, humiliated and looking so ridiculous with that… black silicone thing stuck there.

"Okay, did you… stick it in… too far?" Alex was now trying not to laugh, because what other reaction could she have to something like this? It was either that or stick with that uncomfortable feeling that was whirling in the pit of her stomach.

"Alex…" Kara was close to tears now.

"Oh, Kara." Kara's tears had always been one of Alex's weakness, and Alex found herself at Kara's side now, belatedly realizing now she was up close and personal to the contraption jutting out from Kara's groin.

"Is that, um," Alex frowned at the long black… tubular thing. It was really big. "That's not like, a dildo."

"I don't have…" Kara's voice lowered, the discomfort and the sheer awkwardness would've been funny if Alex didn't know that Kara was a second away from crying. "Well… I can… but… I did it this way."

Alex followed Kara's gaze to the box on the table with a stereotypical bug-eyed green martian on the box, followed by descriptions on how this 'product' was so awesome it was out of this world. Alex waved at the box, not knowing what else to say.

"So… your… thing… is stuck in… that… thing?" Alex tried to be as serious as possible, but she couldn't help the smirk that was growing on her face.

"Alex!" Kara whined, this time actual tears at the corner of her eye. "Please!"

"Okay, okay. Have you just," Alex made a ripping motion with her hands. "Just tried to rip it apart?"

Kara still looked ashamed, but had a slightly scandalised look on her face. "I spent like a hundred bucks on this!"

"Oh my god, Kara." Alex let out an exasperated groan. "I will buy you another one!"

"No! This is already humiliating enough, can you PLEASE help me get this off?" Kara pulled at the black… fleshlight, wincing as she did so.

"Hey, hey, hey. That can't feel good." Alex tried to take on a purely professional air. "How did you… how did you even-"

"I put it in." Kara pressed a cushion over her own face, too embarrassed to be having this conversation with Alex looking at her face.

"You put it in."

"I… I put my… my thing into this thing. And then… it felt good for a little bit." Kara's voice was muffled and Alex tried not to laugh at how miserable Kara sounded. "But then it… it was too… rough?"

Alex frowned, thinking a bit. She picked up the box off the coffee table to examine it.

"Don't look at that!" the cushion was thrown to the floor and Kara made a mad grab for it, Alex holding it out of reach.

"Stop that. I'm trying to read the instructions. We're trying to solve this." Alex cleared her throat, using her teaching assistant voice. "It says, 'pour lube in and enjoy'. Did you pour lube in?"

The throw on the couch went over Kara's head.

"Kara." Alex put the box back on the table.

"No. I didn't."

"You just… put it in."

"... yes. Oh my god can we just not talk about this?"

"Did you try to…?"

"I tried everything! I was trying to… to make it feel good again, and maybe I would… make some… lubrication…" Kara's words ended in a garbled mix of barely understandable English and Kryptonian. "But it just hurt!"

"We might have to just rip it-"

"Do you have lube?"

"No. I don't keep lube in the nightstand on my side of the bed that I share with you, Kara." Alex deadpanned. She rubbed her chin, really trying to solve this conundrum. "Unless… vegetable oil?"

"No, oil degrades the silicone."

"So you can research lube but not remember to use it?"

"I forgot to buy it, okay? And I was just… I thought… I was just so ready!" Kara wailed. "Can you just bury me in a hole?"

"Again if you rip-"

"No, it's like two hundred dollars!"

"You said a hundred!" Alex gaped at Kara.

"The website said this was the best!"

"How is some silicone worth-oh my god, I'm not going to ask. Okay." Alex looked at the black tubular thing. It was almost translucent, but the black colouring hid Kara's… thing a little bit. Alex could still see the outlines of it, which was moving very minimally since it was entrapped.

"Can you withdraw it back in-"

"No. I'm-no. Just, no. I can't."

"Alright. Okay. Okay. Um." Alex watched Kara… wiggle minutely inside the silicone trap. "Maybe human sex toys weren't made for… alien genitalia. Um."

"Alex." Kara drew out the last syllable in a plaintive whimper, her face appearing from under the throw. The sound of Kara's voice… did things to Alex. Alex could feel the flush crawling up her neck and deliberately looked down at the silicone toy more closely, trying to avoid looking Kara in the eye.

"You've been pulling. Maybe try… wiggling it side to side?"

Kara eagerly did as told, but after a good maybe twenty seconds of trying, Kara was close to tears again.

"Kara, you're hurting yourself." Alex placed a hand on top of Kara's to stop her from trying. Kara went still at the touch of Alex's hand on hers.

"Can I… can I try?" Alex was trying not to die of embarrassment. But Kara was just too impatient to wiggle herself out of it.

"Um." Kara put her hands down in the couch, watching Alex with a strange look on her face. "Uh, yeah. Sure."

As gentle as she possibly could, Alex took the silicone toy in both hands. Kara sucked in a breath slowly through her teeth, as Alex got a firmer hold on the silicone toy and tried to twist it carefully but stopped at the grunt Kara gave. Alex then tried to wriggle it upwards and off Kara's junk, as gently as possible. Kara let out a low hiss, as the silicone stopped moving upwards.

"Seems like you've created too much suction." Alex hummed, not looking up at Kara's face. Alex gave the silicone contraption an experimental squeeze, and Kara let out a low, strangled groan.

"Sorry did that-"

"No, it's… " Kara's eyes were closed and her hands were fisted, pressed against her side. Alex didn't know what possessed her, but she gave another slow squeeze of her hands. Kara's head lolled bonelessly to drop back on the headrest, the noises that escaped Kara's throat filled Alex with a heady kind of weightlessness.

"Kara?"

"It… it feels good."

"Oh."

Alex didn't know whether to stop or not. Her heart was pounding and Alex was trying frantically to catalogue the responses her body was giving and explain away why she felt such a deep jerk low in her abdomen when Kara had responded to her touch. Alex dealt with these confusing feelings by trying really hard to just systematically and clinically keep a checklist of the way her body felt. That really didn't help, though, to focus on how her body was agonizing over… something… and the feeling of that something welling up inside her. Alex felt like she was drowning.

"Alex… try… again?" Kara panted, sounding so much like she was begging.

So Alex gave another little squeeze that had Kara's hips pumping up once in a short, powerful thrust that petered off into lazy undulations of Kara's body. Alex watched, entranced, on the precipice of some horrible feeling, watched Kara fucking into the toy, into Alex's clenched hands.

"Alex?" Kara's voice was high and breathy. "What… what is this?"

"Sorry, I just wanted to see if it would, I don't know, help. But if this-I'm sorry, I'm really sorry, I know this is probably really bad touching, so… oh shit. Oh shit, is this bad? I'm sorry. I-" Alex let go of the toy, wiping her hands on the front of her jeans, then used the back of her hand to swipe at the sweat beading on her brow.

"No." Kara still sounded breathless. "I-I think… it's helping? It's helping so… please? Please just… continue. It's okay. Really, Alex."

Kara watched Alex, her eyes half-lidded, her movements lethargic. But when Alex placed her hands around the toy again, she could feel Kara pulsing inside of the silicone encasement. Alex had to break eye contact, giving a wordless nod as she squeezed again, testing the give of the toy, wondering how it felt like, what IT would felt like.

"Alex." Kara's hands, clenched at her side were shaking, from the strain, her hips lifting up off the couch. "Please."

Alex gave small rhythmic squeezes, staring at Kara's… thing, twisting inside the confined space. This was… all a bit much. But Kara needed her help and Alex knew maybe this was a bit TOO MUCH and she should've insisted on opening up this silicone trap. But this was fine. This… was fine. If Alex repeated that to herself enough times, it might just be true.

As Alex squeezed, she tried to come at this in a more… analytical way. If she pretended this was just an experiment, then this wouldn't be weird. Alex could see how there were some wet spots inside the silicone toy, could hear that there was give inside the silicone toy.

Meanwhile, Kara was giving these slow wave-like thrusts, putting her whole body into the movement, the wet, squelching noise of Kara moving inside the black-coloured fleshlight filling Alex's ears. Alex tried to keep it… methodical. Kept track of the pressure Kara liked, adjusting the grip of her fingers, trying to give minute little pumps to work the lubrication around the inside of the toy. Alex concentrated on the sounds Kara was making, the deep groans and the barely audible whimpers, and occasionally, the whispered Kryptonian word or two that would make Alex's ears burn and caused her insides to clench.

"Alex… Alex, please. Please. Please, please..." Kara was begging so nicely, her feet planted on the floor of their apartment. Alex didn't know if Kara was trying to stop herself from thrusting up into the enclosure of Alex's hands or was trying to get more leverage to do so. There was enough lubrication inside of the sleeve for Kara to slip out easily.

Kara let out a little mewling noise of displeasure as Alex, with a last tightening of her hands, pulled the device off gently, the truly obscene 'schlorping' sound of Kara coming out of the trap almost made Alex choke on her own spit. Kara's thing came out, bulged and engorged, a deep scarlet colour before it shifted quickly to a iridescent blue, then a violet.

"It's fine, Kara. You're out." Alex rubbed along the jut of one of Kara's hips, holding the silicone toy in the other hand, opening facing upwards, so it wouldn't drip all over their floors.

"I'm not done." Kara's eyes met Alex's pleadingly. "Alex…"

"Kara." Alex didn't know what kind of expression was on her face but it made Kara's face fall.

"I'm sorry. I'm sorry, this was totally inappropriate. I apologize." Kara covered her junk with one hand and Alex couldn't stop her eyes from wandering down to this… thing wriggling underneath Kara's hand.

"Please stop staring at my ovipositor." Kara implored.

"Ovipositor… is that, is that like the word for penis?"

"No, this isn't a penis. It's an ovipositor." Kara cupped both hands over her ovipositor now, as it tried to curl around her fingers or wriggle it's way out between Kara's fingers. They fell into silence again. Just sitting there wordlessly, Alex still holding the silicone toy and Kara, horribly mortified.

"I'm sorry." Kara repeated miserably. "I'm really sorry."

Alex let out a long sigh, then gingerly placed the silicone toy in the box on the table, so it stood up and it wouldn't spill.

"Is this part of your Stage of Growth?"

"Yes." Kara sniffled. "It's the last part. We register and submit samples. For the Fertility arm of the Science Guild. It's a part that all adult Kryptonians go through."

"Okay, well, so, there's like no sex?"

"No, the technicians deal with that, too. We don't have much desire under Rao's red light, but we have that part of us dealt with, just in case."

Alex blanched. "They… neuter you?"

Kara scrunched her face up. "I… guess. But not like how humans do to their dogs. It's a process that I can't really explain since it'll just seem like it's magic to you. It's fine though, everyone gets it, especially the men with the pouches."

"Seahorses." Alex shuddered, remembering the video she watched once, of a seahorse father giving birth. She was not going to ask about Superman's junk or the birthing process. Definitely not.

"But it's… not like a seahorse ovipositor." Alex nodded at the squirmy mess under Kara's hand.

"Let's not talk about this." Kara was grimacing, clutching at her genitals and trying to get them to calm down. All of this would be hilarious if not for the fact that Kara looked so absolutely unhappy.

"Is this why you've been acting so weird?"

"I was doing research. I don't have Viox to ask anymore or to posit the effects of Earth on my body, so I looked up human mating."

"And you got…?" Alex looked at the box, then back at Kara.

"It was all just porn." Kara said miserably. "My friends are all dating and having sex, but I don't know what that is, Alex."

"Oh."

"And I don't know, I don't know if I'll… hurt anyone." Kara's words were barely audible.

"Kara, did you try to talk to Eliza about this?"

The look on Kara's face said it all. Alex understood right away. Eliza had become a somewhat of a maternal figure to Kara on Earth and was also Kara's doctor, but Kryptonian social etiquette still held strong and Kara would balk at some of the examinations. Usually, AI's not unlike Viox would do all kinds of scanning without touching a person or removing any clothing. It was different for Kara, to get accustomed to the prodding, the customs, the practice of medicine of Earth.

"Alex... what if I can never go on 'a date'?" Kara asked quietly. "What will I do when I get to the sex part?"

"No, Kara. Don't ever think that." Alex shot that idea down quick. "Sex isn't always involved."

"But it is if the person you're with is 'special'. That 'special someone'."

"It's not-"

"But maybe that's what the other person wants." Kara was visibly upset. "What if I can't ever have someone because I can't give them that? If I have to be on Earth, I have to get used to Earth relationships."

"So you just wanted to try that to see if you'll hurt anyone?" Alex nodded at the silicone thing again.

"...yes."

A sudden thought left an unpleasant feeling in the pit of Alex's stomach. "Do you like someone?"

Kara looked up at Alex, the flush on her cheeks having nothing to do with her recent exertions as she nodded meekly. Just the confirmation of Kara's interest in someone, the sign of her really hitting puberty made Alex feel like all the air had been knocked from her lungs.

"Congratulations!" The false-cheery voice sounded shrill in Alex's ears. "Do I know them? It's that weird kid with the patchy beard, isn't it?"

"Don't be mean, Alex." Kara managed a small smile.

"Well, can you… I mean…" Alex waved at the silicone toy, suddenly very eager to help Kara, so that she can at least chase away that feeling that felt like it was squeezing the air from her lungs. "Just…"

"I can… keep my ovipositor inside. But I wanted… I wanted to try that." Kara's ovipositor was now lying limp in her hands, moving sluggishly but still looking swollen and a bit slimy.

"Well, if you want, I can… help? Well, with trying to figure out, like, anatomically how it would work. And I could… supervise?"

Kara shook her head and chuckled. The chuckle turned to an all out laugh and a few seconds later, Alex was joining Kara in the laughter, too. The situation was just so outside of normal. It was one of those situations you just HAD to laugh off or else it would be weird forever.

"When we're old, we're going to look back on this and be like, remember when I helped get you out of that silicone vagina?" Alex joked. Kara stopped mid laugh, choking on air. As she coughed, Alex's attention was caught by how Kara's ovipositor split into… THREE separate tentacle-like thing at a particularly hard cough, before wrapping and twisting together into one squirmy strand.

"Your thing is like a mimic octopus." Alex shook her head. She had never seen Kara's ovipositor up close before. Alex knew what Kara looked like naked, which was very much like a regular human being with what appeared to be regular human female genitals. Now Alex knew for a fact that Kryptonian ovipositors were usually retracted in the body.

"I guess there's some passing resemblance." Kara looked down, her hand slowly stroking at herself before she suddenly seemed to realize what she was doing and stopped.

"I'm sorry."

"No, it's… you know, you can go ahead and-I'll give you some privacy. I can just… you know, just-" Alex got up and waved wildly in the direction of the washroom. "I'll go take a shower."

"Wait!" Kara called out, sounding a bit desperate to stop Alex's retreat. "Um… were you serious?"

"About?"

"About helping me." Kara chewed on her bottom lip nervously. "Because I kind of… I want you to… watch."

It felt like the bottom had dropped out in Alex's stomach and a feeling of anxiety hit her.

"What?"

"Just-just so I don't get stuck again! And I feel better. With you here. This was actually kind of really scary." Kara admitted.

Alex laughed again, not knowing what to say, laughing until she saw that Kara definitely wasn't laughing and now looked a bit hurt.

"You're serious? You're scared?"

"I've never even-I don't know what I'm doing!" Kara pointed at her thing. "I have no reference for this, just porn, which I read was not that reliable. And my case doesn't seem to have any kind of remote Earth equivalent, besides some nature documentaries I remember watching. Anyways, if you could treat me like a test subject or something, help me find out more about my… condition… then it won't be as scary."

Alex opened and closed her mouth a couple of times, doing a pretty good impression of a fish. Alex was stuck. She had offered to help… but hadn't thought of what that help would actually entail.

"Kara-"

"It's okay." Kara waved her hand frantically, then slapped it back on her ovipositor which had started comically looking like it was… waving at Alex. "No, I get it, it's a stupid idea."

"No, Kara, I-I'm not that experienced at all. I'm not a pro on this topic." Alex chewed her bottom lip nervously. "It's not like I've had sex yet."

"What?" Kara seemed stunned. "But you've gone on dates-"

"What did you think I did during those dates?" Alex was slightly offended.

Kara shrugged uncomfortably. "I don't know. I don't like to think about it. Not after… well. I just tried to ignore it."

Alex knew that Kara was referring to that time when Alex was supposed to go to Rebecca's house for a sleepover.

"Kara," Alex had always been so tactile with Kara and couldn't help touching Kara's knee, trying to ignore how Kara trembled under her hand. "I didn't do anything. The closest to ANYTHING was when I was making out with one of the guys that my friends had set me up with, and he kind of… blew in his pants."

"Ew." Kara breathed out, sounding disgusted but also a bit… relieved?

"Yeah. So." Alex shrugged uncomfortably. "If you want me to, I don't know, watch you so you feel more comfortable, um, sure. But I can't give you tips or anything because I firstly have no relevant experience and secondly, your thing is literally from out of this world, as are you."

"So… you'll watch me?"

"As long as we never tell my mom." Alex winced, the image of Eliza clear in her mind's eye. "I do not want to explain to her what we are doing."

Kara crossed her heart with one hand, her eyes zeroing in on the silicone toy resting on the table, absolutely ready to continue her experimentation. Alex sighed, picked it up and handed it to Kara.

"Alright. Do you want me to just, um," Alex scooted backwards to the far end of the couch. "I'll be here, kay? Just watching."

"Okay." Kara sat with her legs crossed under her, settled back into her side of the couch, facing Alex. Kara's nervous smile thinned into a look of determination as she held the toy over her ovipositor.

"Oh, one second." Alex jumped off the couch and was back with a pad of paper and a pen from her discarded bag that she had left on the floor. "Okay, go."

"Alright-"

"Wait." Alex stopped Kara again.

"Whaaaaat?" There was a definite whine in Kara's voice.

"Are you just going to just jam it in?" Alex looked at the toy dubiously, and the wriggling mass protruding from Kara's nether regions.

"Sure!"

"No, this is how you got stuck last time." Alex sighed. "Can you-can you put it in slowly?"

"How?" Kara pouted.

"Slow. Just take your time."

Kara frowned but did as told, holding the opening of the toy towards her genitals and inching it slowly towards herself. Splitting into four, the ovipositor twisted itself together again and corkscrewed into the toy slowly. The entry was accompanied by Kara's almost soundless exhale. Just a little staccato of sound, a puff of air forcing its way out of her throat.

Alex watched in fascination as more of Kara's ovipositor slipped out of Kara, filling the black-coloured silicone. It was a slow-moving, pulsing mass, and the ovipositor seemed to be able to piston itself forward. It reminded Alex of how snakes moved.

"Can I ask questions?" Alex inquired, stopping Kara in her tracks.

"Umm… Mmm… yes." Kara nodded, before continuing her slow push into the toy.

Since Kara had managed to lubricate it-'with my help' Alex thought, before slamming down on that thought-Kara was slipping inside smoothly, her coo of pleasure raising the tiny hairs on Alex's forearms.

"Do you, I mean, is it moving by itself?"

"Y-yeah."

"Like, are you controlling it?"

"Mmhm." Kara hummed, plenty distracted, but eyes intent on Alex's face.

"So you don't use your hips-"

"Alex… when you…" Kara interrupted her sister. "...how do you… was it-"

"I just, like, with my hands." Alex knew what Kara wanted and tried to explain as best as she can, using her hands to make an awkward squeezing motion with both hands. "Kind of like, how sometimes… you know."

"Alex… what… what do you mean?" Kara's eyes shone with curiosity.

"Just… like how a girl might feel. You know, inside." Alex mumbled. But Alex knew Kara could hear her, saw those blue eyes blink at Alex behind her glasses, before taking on an excited gleam.

Kara looked down at the toy in her hand, giving an experimental squeeze before going a bit slack-jawed, her eyes closing at the sensation of the pressure. Alex saw Kara's hips jerk up messily trying to thrust into the toy but only succeeding in popping out of it, dribbling a clear viscous substance onto the towel on the couch, the same substance oozing out of the toy.

"Kara," Alex watched, wide-eyed as Kara, eyes still closed, tried to unsuccessfully stuff herself back into the silicone vagina, groaning in frustration when she only managed to miss the mark, smearing the outside of the silicone hole and her hands with the thick, clear liquid.

"Slow, Kara." Alex tried to keep her voice low and calm, despite feeling like she didn't have enough air, the shallow breaths she'd been taking was doing nothing to get rid of that drowning feeling.

"Alex. Alex… … oh." Kara groaning out her name as her ovipositor seemed to heed Alex's instructions and carefully slithered back inside the toy.

Kara calling Alex's name stirred a feeling almost like pride in Alex, an egotistical pride that she could make Kara feel like this. And selfishly, Alex was proud that she was probably the first and so far the only one to make Kara feel this way.

"Is that… how you feel?" Kara was looking at Alex again.

Alex avoided Kara's scrutiny, jotted something down, some inane observation so it would give her something to do while Kara's gaze remained on her.

"Is it, Alex?" The haughty tonal notes of Kara's native Kryptonian sent a shiver down Alex's back.

"Yes." Alex tried to act distracted, tried not to meet Kara's eyes. Maybe this wasn't such a good idea. Kara's low groan hit her right in the guts, and it was making Alex feel kind of like the thermostat had been turned way up.

"Do… all girls… do that? Squeeze?" Kara's breathing was a bit reedy.

"I'm not sure." Alex squirmed in her seat. Kara paused for a second, straightening her legs out in front of her but keeping her knees bent. Planting her feet on the sofa and still facing Alex, Kara pumped in and out of the tight silicone enclosure in slow motions, her hands squeezing sporadically.

"When? When do you…?" Kara asked. Alex shrugged, embarrassed by where this conversation was going and how Kara's eyes never left her face.

"When I'm, um," Alex licked her lips nervously, trying to think of the words in Kryptonian. "When I… when I need. When I want."

"What… do you… need? What do… you want?" Kara kept asking questions and Alex squirmed uncomfortably, mortified that she felt wet. That this little exercise that she was doing with her Kara, who was supposed to be her sister, was making her REACT. And when Alex looked at Kara-flushed, clueless, trusting, Kara-she could feel herself, feel herself NEEDING, clenching on nothing, dripping with the evidence of how incredibly turned on she was right now.

"Alex-" Kara let out a little choked cry, rolling onto her knees, her eyes dark and focused in on her. When Alex saw Kara's nostrils flaring subtly, she knew Kara was picking up her scent.

"Don't smell!" Alex protested, crossing the distance of the couch to slap Kara on the shoulder lightly. "Don't!"

"But… you smell so good." Kara chuckled, low and deep, the low fire in the pit of Alex's stomach roaring into an inferno at that horribly attractive voice. Kara was close enough to scent at Alex's neck, snuffling lightly, centimetres away from Alex's skin.

"This is your fault!" Alex proclaimed, flustered.

"How… is this… my fault?"

Alex froze when the Kryptonian leaned in even closer to sniff at her, crouched over her, hands still wrapped around that ridiculously contraption. Kara pressed her nose against the exposed skin of Alex's neck, laying her head on Alex's shoulders, breathing heavily through her mouth.

"I'm… scared." Kara admitted, her breathing shaky. Alex replied by wrapping her arms around Kara's back and holding Kara as close as possible, without getting in the way of what Kara was doing. Alex held Kara tightly as she moaned into Alex's neck, Kara's hands working between them. Alex was afraid to move, just held on tight, her breathing getting as ragged as Kara's, feeling the flex of muscle as Kara's body heaved and quaked, responding to the pleasure.

Alex held on through the shuddering jerks of Kara's frame, through the frantic, irregular breaths of air that tickled Alex's skin and made Alex shiver. Alex held on when Kara pressed her mouth against Alex's neck suddenly to muffle her groan when Kara started spasming. The reverberations of the sound through Alex's skin sending something like electricity coursing through Alex, the tight feeling in her stomach exploding into something warm and liquid.

And when Kara finally slumped bonelessly onto Alex, Alex held on and leaned back, using her body to pillow Kara's. Alex had to clear her throat a couple of times before she could get the words out.

"Are you okay?"

Kara nodded and mumbled, sated-drunk, her head still nestled at the crook of Alex's neck. Alex rubbed her cheek against Kara's forehead, knocking against Kara's glasses, wondering at this sweet scent in the air. Kara lifted her head to nudge her nose against Alex's jaw affectionately, almost like a cat. And when Kara's lips followed and lingered against Alex's face, Alex didn't make a sound of protest, just held her breath and wondered what would happen next. Could feel the question in the air, in Kara's body, stopped mid-movement so Kara could regard her. Kara nuzzled against Alex's cheek again, testing that boundary, breathing in deep, and letting out a tremulous sigh that tickled Alex's neck when Alex didn't withdraw or push Kara away.

"Alex-"

Alex's stomach let out a loud growl, destroying whatever moment they were having.

"Oh, you haven't eaten." Kara struggled to get up, placing her toy carefully on the coffee table. Alex glanced down, blushed, and looked back up right into Kara's eyes, both knowing what she had been staring at.

"It… went back in." Kara mumbled. She sat up gingerly, then stood, running her hands down her abdomen and thighs, making a face at the stickiness left behind. "I'm going to clean myself up real quick and then get dinner ready for you. I-I saved you something."

Before Alex could reply, Kara had already zoomed away. Alex was left sitting there, feeling like her world had shifted sideways. The only thing she could do was pick up her pen and pad of paper, jotting down all her observations as quickly as possible.

It was just an experiment. It was just Alex helping someone understand the effects of Earth on their alien bodies. It wasn't unlike observing and dealing with reactions to the common cold on some aliens. What she did was… fine. It was fine.

Alex wrote a title to her paper-she decided it would be in the format of an academic research paper-and reassured herself that many notable scientists, like Dr. Alfred Kinsey studied sexology and were well-regarded by the population at large despite the scandalous nature of their topic at the time.

"Fuck." Alex put her pad of paper and pen down, running her fingers through her hair, belated remembering what her hands had been doing just before.

"Alex." Kara, fresh out of the shower, had already changed into a tank top and comfy flannel pants. "Are you okay?"

"Yeah," Alex waved Kara away. "I'm okay. I just need a minute. Shit. Shit shit shit."

"Alex, it's okay-"

"No, I feel like, what I did… Kara, I'm sorry, I shouldn't have. If-if it was weird, if you don't feel comfortable-"

"Stop freaking out, Alex. It's fine. Really." Kara gathered up the towel on the couch, making sure that none of her… secretions… had leaked through, shaking her head. "I should be the one who's worried, you know? I wanted you to. I asked you to do it so if you're thinking you did anything bad to me, it's not your fault. Did you-was it not ok? I'm sorry if-"

"No," Alex let out a sigh of frustration. This wasn't the problem. She had been willing to do it. She knew Kara wanted her to, accepted that Kara had told Alex in no uncertain terms to help her. "It was fine, Kara. I'm glad I could help."

"Then it's fine with me, Alex. Really." Kara still looked happy and sleepy, her features relaxed. "You really helped. I've been feeling really like, you know, restless and kind of like, how you were saying you needed something. I felt… itchy, um. Yeah. And you got me out of my toy."

Kara picked up her toy and zoomed away, leaving Alex with her thoughts for a minute before zooming back sans towel and toy.

"Go change into something more comfortable, I'll reheat the food I left for you." Kara shooed her away. Alex obeyed, still too overwhelmed to say or do anything. The day was catching up to her and what had just happened… she needed more time to process. So Alex pushed it all into the back of her mind, and went to the bathroom and stripped off all her clothes.

"Take a quick shower! The food's gonna be quick!" Kara's hollered. Alex answered back in a normal volume, knowing Kara could hear her. Then she stood there, naked, just looking wearily at herself in the mirror. Alex could still feel the tension thrumming through her body. Whatever happened tonight had changed something intrinsically in the sisters' relationship, and Alex didn't know what to make of it.

But right now, all she could see in her mind's eye was Kara, her foster sister, fucking into a silicone toy, watching her with bright blue eyes behind black-rimmed glasses. And Alex could feel herself growing slick at the thought, her body more honest than she will ever be. Alex's body was telling her exactly what she needed. What she wanted.

Who she wanted.

Who she needed.

Wearily, Alex dragged herself into the shower and hoped that the water set to freezing would wash away these truths.
