"Why won't this stop?" Ryuko groaned, the pillow clenched between her knees as she bucked against it wildly, cock drooling pre onto it as she did what she could to handle herself. It was embarrassing as all hell to know that once she took up Senketsu's power, she had grown a dick. Not a big dick. Just a normal looking, maybe average-ish penis. But a penis between her legs. Balls too. Her body had been changed in ways that she wasn't going to fight over too much as she just tried to work through things and live a life as normal as she could get. Her genitals really were not as big a concern to her; there were much bigger, much more important things in her life.
But here, in nothing but her pajama top and her panties, she was desperately trying to make her dick go down again.
It was hard at the worst fucking times. She wasn't even always aroused when it happened, it just got hard out of nowhere and she was left fumbling her way through dealing with the most embarrassing of sensations. The tenting in her skirt and the strain inside of her white and blue panties was infuriating. Her panties were being made a total mess of with her cum, which she now produced. Not in any ludicrous volume, but to someone who wasn't making semen up until a few weeks ago, the volume was genuinely troubling. She tried to work through it and work around it, but she failed miserably.
Ryuko's go-to technique was pillow humping. Grinding away at a firm pillow and riding it out was the best way to go, with some occasional touches here and there to add onto things. It was all very simple, all very steady and understandable, and Ryuko felt confident in all of it. But with a dick, that wasn't working out for her like she wished it would. She didn't cum quite right, even sometimes having half-orgasms where she came a bit but felt little from it. Penises seemed like weird, unwieldy things she hadn't even the first inkling of how to manage, and Ryuko was far too embarrassed to want to ask anyone for help. Who would she even ask? Barazo? No, that wasn't happening.
So she did it herself. With her dick pinned down between her body and the pillow, sticking out the top of her panties and occasionally leaking pre, she did her best to give up to the pressures hitting her. Even if it didn't always feel particularly rewarding, the only way to make it calm down and cooperate was to force the issue. Her hips moved with the burning, dizzy pressure and panic she was trying to work through, and each push felt just that little bit better, trying to deal with this pressure to the best of her abilities. Ryuko worked harder at this, worked to bring around some shred of focus while desperately seeking relief. As frustrating as it was, she needed this.
Cumming under all this attention and excitement was her only real shot forward, and she threw herself readily into it, a gasping mess ready to come apart at the seams under what rushed through her, and she was devoid of sense through all of it. Groaning, grunting, and gritting her teeth, Ryuko tried not to make much noise in all this commotion, not wanting to bother anyone or wake up Mako. It was her most hopeful way forward, the desperate, hard-fought relief she needed and the only way to handle herself. This time, she got some hard-fought relief, groaning her way through cumming all over the pillow and her top, and she felt some shred of relief and sense as she ached through this, slowly grinding to a halt and then finally pulling off of the pillow entirely.
She stuffed it under the blanket. It was one of a ton of pillows in the house, and she never rested her head on it. It got hidden between her legs as she slept. Sometimes, she woke up hard and already grinding on the pillow. But what was important was hiding it from everyone out of embarrassment, and as she felt the post-nut lethargy start to take her, Ryuko was at least confident she could slide into slumber without problem, breath slightly shaky, and the warming sensations coming on with shaky, aimless delight.
******************************
"What is this?" Mako asked, staring at the cum stains inside of Ryuko's panties with terrified eyes. She shouldn’t have been creeping around in her friend's underwear anyway. Her offer to do the laundry absolutely wasn't about that at all, she promised. But once she saw the crusty, white stains there, panic set in. Someone was using Ryuko's panties and cumming in them! Mako definitely hadn't been doing it, which was reason enough for her to be absolutely furious, barging out of the bathroom holding a pair of Ryuko's used panties and rushing into the room to alert Ryuko to the problem. She suspected it may have been her brother, and she figured she should warn Ryuko and see what she'd do with the information.
Rushing into the room, she was ready to warn Ryuko of the rogue pervert soiling her panties, but as she barged into the room, she caught something else.
With Mako off to do the laundry, Ryuko hoped she could get away with masturbating before she got back. It was just a quickie, but as per usual, she went for the pillow, hunched over it and feverishly rubbing, cock begging to let go, but as the door swung open, Ryuko got only about three bucks of her hips in before realizing she was being watched, shrieking and falling off of the pillow, a whining mess trying to hide herself. "Mako?" she gasped. "What's going on? W-why do you have my underwear?"
Mako stared at the bulge in Ryuko's panties. The telltale swell of a cock caught her eye there, and realization dawned quickly on her, realization coming on even stronger as it hit her. Nobody had been stealing Ryuko's panties to cum in; Ryuko was the one cumming in all of them. "You too?" she gasped, eyes widening, still holding a pair of Ryuko's panties.
"Put my underwear down!" Ryuko shouted. She hid herself away from view, pivoting into a precarious position just to avoid being exposed like this, burning with absolute panic as she tried her best to cover for this now, failing miserably at playing convincing. She had been caught masturbating, and she knew it.
"I thought it was just me," she said, rushing forward, eyes gleaming. "You're so cool but now I know you're trans, too!" Mako wasn't exactly a calm or composed girl in the first place, but she found herself burning with even more energy than normal. "We have so much more in common!" She pushed forward. "It's great. It's great! I feel so much better knowing I have a friend who understands. But you could have told me sooner!"
The degree to which Mako looked overjoyed and excited made Ryuko briefly almost lie about things, but she had to tell the truth. Had to say it to someone. "I'm not, sorry," she said. "This penis grew when I started using Senketsu. I wasn't born with it, it just showed up. But thanks for trusting me enough to share!" That last part came on as a clumsy afterthought in the realization that she had just been opened up to in a major way by Mako, and she didn't want to come off like she was ungrateful or judging her at all. Mako was still her closest friend, no matter what, and she didn't want to leave any doubt or question about that.
Mako wasn't sure exactly what to make of that. She believed it, but it sounded weird to her. "Well, we still understand each other!" she said. "Two girls with dicks. Best friends! With dicks!" She was ready to spin this into a positive. I found cum stains in your panties, and I was so scared that my brother stole them to jerk off into, but no. It's just you! A-are you okay though? You're cumming in them a lot."
"Yeah, it's fine. I guess. I don't really know what else to do. I'm trying my best to get off, but it's tough."
Mako tilted her head in curiosity. "It is?" Even if Ryuko was new to having a penis, she couldn't have been having that much trouble, right?
"Well, it's so much work! Grinding against the pillow and trying to cum takes so much effort."
"You don't grind on the pillow." Mako drew closer. "Ryuko, you don't know how to masturbate."
Ryuko's cheeks lit up. She didn't? That was bad enough, but the real trouble was the fact her eye caught the stir of something tenting at Mako's skirt. She sucked down a nervous breath, her thighs pressing together as she tried to hide her bulging panties. She was still hard, too. "How am I supposed to masturbate?"
"Can I show you?" Mako was even closer. Incredibly close. If Ryuko didn't want her to be here, this was probably too close. But Ryuko wanted her there, and she was in fact just close enough. Her hand drifted slowly forward, inching toward Ryuko and offering to help.
For someone masturbating as much as Ryuko had been, she felt like she didn't understand this body part in the least, and like all of her frustrations tied into not knowing how to 'do it right'. But if she trusted anybody to help her, it was Mako. She trusted Mako with everything. "You can show me," she said, her legs loosening up, opening for her friend as she sat nervously there, looking up at Mako. "I really need to get past this."
Mako was ready for it, slipping her hand down Ryuko's panties and gripping her cock with a confident, firm squeeze and a readiness to do what she could for her. "The best way to masturbate is to use your hand," she said, gently wriggling Ryuko's panties down so that her cock poked out and she could better grasp it, having the freedom and motion needed to stroke along it. In contrast to everything Ryuko expected out of Mako, she approached stroking her dick with a careful, calm pace that took its time with her. "How's that feel?'
The firm grasp of a hand taking hold of her dick made Ryuko shudder, and the strokes caught her off guard, made her head ease back. The feeling was a lot more than she'd been getting by rubbing against something. Especially with how warm and soft Mako's hand was. "That feels better already," she said, looking up at Mako's smile, then down at the caress of the hand pumping along her cock. The direct application of pleasure in ways she had never felt better hit her with a lot more intensity than she was expecting to feel, but she was ready to open up to all of it in pursuit of some sort of relief. "Should I--can I try it on you, too? For practice." Those last two words came out hastily, pushing on with a good, big excuse for why she wanted to touch Mako's dick.
"Of course!" she said. "Just reach under my skirt and do everything I'm doing." Mako couldn't help but keep looking down at Ryuko's dick, a strange excitement washing over her as she kept up with all of this. Even if she wasn't born with it and had a penis for reasons that still didn't make any sense, Mako was glad her best friend was in a similar boat to her in some way, and she used that excitement to keep pressing on with the stubborn fever of needing to give her the pleasure and lesson she offered.
Clumsily, Ryuko shoved her hand up Mako's skirt and reached into her panties, taking hold of her dick and beginning her clumsy attempts to mirror everything that Mako did for her. She had her work cut out for her here, trying to find a good angle of approach on this while working in careful, precise motions that focused on meeting her pace. The feeling of a dick in her hand was a lot to take in, doubly so given it wasn't her down dick, but she was desperate to learn and eager to find some way to keep up with all this weirdness as she gave in with careful, hungry motions back and forth to tend to what was being asked of her. "Am I doing it right?"
"It's great!" Mako said, smile brightening as she urged Ryuko along, begging her to keep up with all of this. "You're doing great. Just keep stroking at the same pace I am." Some moans escaped from her mouth as she kept things slow for perhaps the first time in her life. It was right to, giving Ryuko the time to focus and to take care with her every motion, not getting too caught up in anything or worrying about the overbearing pace that any of this could push. She was careful, steady, and with all of this fine control came something that steadily intensified the pressures between them. The patience and the control behind all of this needed precision, and she worked with great care and precision to keep up with all of it.
The pillow didn't compare. Ryuko felt amazing, the pleasure shuddering its way through her body with something utterly primal. She didn't hold back her moans, even if the volume of them was probably a bit suspect and overbearing. Ryuko just felt so good, and everything inside of her pleaded for this chance to let go, embracing the bizarre pulses of heat that shook her. She needed to do something to keep herself steady, dealing with the eruptions of desire and heat that found their way through her. Pumping along Mako's cock and trying to keep up with this was an incredible feeling, and feeling the hand keeping its pace helped hold her on track, urging her along in the loving pace she showed the dick in turn. It was all she could do to praise and adore her.
But it felt amazing. The cock throbbing in her hand urged Ryuko on just as hard, as she realized how good she was making Mako feel. She was doing a great job here, and the two girls reduced each other to moaning wrecks both needily stroking one another, completely lost in this spiral of desire and hazy need, loving every second of what they could do to the other as they gave in deeper. It was a lot to take in, and every motion felt like a chance for them to continue losing themselves to it, growing more eager and fitful in their desire and their fever. Together, they were in a spiral downward that left them both feeling incredible, and there was no reason for either to slow it down. Not when it was taking such a grand and excitable toll on them both.
Working at the same pace helped even up the gap, Mako and Ryuko both going at this with little in the way of sense. They were getting closer, stroking one another and urging themselves closer to ruin, when Mako said, "I really like the feeling of cumming in my panties. "And you have such cute panties." She used her free hand to tug the blue and white striped underwear back up, even if it made her hand clumsier, and did the same with her own, restricting Ryuko's movement a bit. "Really, really cute panties! They're so sweet. I did think something a little perverted when I saw them, but I promise, I didn't do anything with them before I noticed the stains!"
Ryuko found herself too worn down and shaky to care. "That's fine," she moaned. "I just want to cum. This is so much easier!" She was sure that doing it with Mako had an effect, but the feeling of being pushed so much quicker toward orgasm than normal was exciting. It would sometimes take so long rubbing on the pillow. Here, it wasn't very long at all until she was losing herself. "I'm going to cum! Mako!"
"Ryuko!" Mako gasped, just as ready to give in. Together, the girls came in their panties, blowing their loads into it and making gooey, warm messes out of their underwear. Shivering, staring at one another, both felt a sense of relief hit them as they drew slowly back, as they let the pleasure linger a moment. "You did great."
Slumping back with her breath right and her cock pulsating, Ryuko felt better than she usually did when she came. Not so ridiculously or overbearingly better that everything in her life was different, but it felt so much more direct than her trying to ride the pillow like she still had a vagina. And now she had proof of that, slumming there, feeling the hand still holding onto her dick as she looked at Mako. "Thanks," she said softly, breath shaky. The hand was still on her cock, and she found herself clumsily aching her way through wondering if she should ask if they could do more.
Mako looked down at Ryuko's panties again, more fixated on how her dick looked in them than on her dick in general. "Can I try your panties on?" she asked. There was such a hopeful, shaky look in her eye. "A fresh pair! I mean a fresh pair. But they... They look really cute. And they make your dick look cute. I want to see if they make mine look cute too!"
Ryuko had gone along with a lot already, and so far, this thing with Mako was more enjoyable than the bulk of what she had messed with or fumbled into. So she went with it. "Sure," she said, biting her lip. "I think it would look cute, and I want to see."
Mako hopped up to her feet and rushed to where Ryuko's underwear was without asking or letting her get it, just going straight for it in a fitful and aggressive push to get the pair she wanted. One to match Ryuko, given all her panties were the exact same stripe pattern. She let her own drop and hurriedly tugged the underwear up her legs. "These are so cute!" she shouted, pulling them up and then tugging her skirt up to expose the way she bulged out against the blue and white stripes. "Do I look good?"
Ryuko was getting hard again already as she nodded in firm, needy approval. "It looks great," she said, doing nothing now to hide her arousal, or to hide the way she was giving in to this. "You really like panties, don't you? And cumming in them."
"It's so much hotter to use these to cum in than to use some napkins," she said. "And I love how it feels on me. It's so snug." She bit her lip, drawing slowly closer. "Hey uh. You know, there is a way that you can feel good with grinding, you know. It doesn’t always have to be hand stuff."
The information itself wasn't all that important to Ryuko. Masturbation tips didn't mean too much to her after that very satisfying orgasm she'd just had, but Mako sounded like she was offering a chance to get off again, and if it was with Mako, she was all ears. "How?" she asked.
Taking it as an invitation and throwing herself forward with a hasty and eager need to throw her way into this, Mako pushed against Ryuko, urging her to lie on her back as she straddled her, tugging one of Ryuko's legs and settling it down over her thighs she pressed her bulged-out panties up against Ryuko's. "Something like this," she said softly, smile growing as she began to grind against her. "The pillow isn't going to do as much for you as this will."
Ryuko groaned as she felt the cock press against hers, both of them grinding together while stuck inside of the panties. "That's nice," she moaned, staring up at Mako with an excited desire to see where this could all go. "You feel a lot better than my pillow."
Mako had done a good job of containing her excitement, but her patience did have limits, and as her hips began to rock aster and greedier along, she felt herself getting more fitful and excitable, pushing in with a pleasure and a heat she felt much more direct and much more ready to go all out with. Her hips had significantly more urgency to them this time, expressing deepening desperation and a desire to keep riding this all out, unable to hold herself back and begging to give in to the spectacles taking her. It was a lot, and every motion of her hips provided her with just what she needed. This was a kind of grinding that Mako could get behind, and pressed down just a bit more snugly still against Ryuko.
Grinding her hips about in steady motions, Ryuko knew she was only just adding in to what Mako was taking point on, as the overbearing throbs of pleasure kept her falling deeper, kept her feeling utterly spectacular in the weight of shaky need pushing her. She didn't know what to make of most of this, falling ever lower into a state of baffled heat and of confusion too grand to be able to handle. Mako was doing all the work, contrasting the pillow Ryuko had to ride by doing all the riding herself. But more than that, the feeling of a cock rubbing against hers with only the fabric of their underwear between them made for a radically different feeling, made for something that they could lose themselves too fully. It was maybe too much to handle, but that only made it more exciting to hold firm against.
Ryuko had already blown a load in her panties, forming a wet spot bleeding through that Mako paid extra attention to as the cum began to dampen her own panties. She focused on rubbing her head there in particular, not getting her panties that wet, but certainly adding a bit extra to it, adding a sensitivity that had her moaning out even louder. "I knew this would feel amazing!" she gasped, head rolling back and every sloppy motion of her hips adding into this. Mako was breaking ground here too, and it felt like amazing ground to break.
Their moans were even more fitful and excitable in this state of raw desire, the delight burning hotter through them, and there felt like way too much here that neither knew exactly what to do with. Ryuko and Mako both soaked in the intimacy of this, eyes locked as they used this as their way to bond together, growing hotter and greedier through every throb of delight that took them. It felt incredible, bringing them deeper satisfaction and an appreciation that didn't want to stop. They were getting closer, bodies grinding harder and hotter back and forth in the senseless, dizzy embrace of pleasures that had them both locked in place, desperately trying to deal with this and to give in in a way they could enjoy.
And then, finally, they lost themselves. Gasping out in unison again, they let each others' names ring out as they came into their panties. There was no restraint, no sense. No moment where either tried to contain themselves. They came again, Ryuko adding onto the mess in her panties, while Mako happily blew her own load into another pair of Ryuko's underwear, finding a twisted thrill in doing so. Even as her cock let loose, she was happily bucking about, still riding along and heaving her way through these pleasures. Dizzy need and a ferocious desire to keep riding out left her shaky, frustration still lingering through her as she reached about, biting her lip and slowly grinding her way to a halt.
Their breath was tense, bodies clinging tightly together, and even the gooey afterglow was all the better for how they could linger warmly together like this.
Ryuko wasn't sure what to make of it, but as Mako pulled back and looked down at her panties, she knew two things. One, she was going to need some more underwear, because it seemed like she'd be sharing. Two, masturbating was going to get a lot more exciting, and probably never have to be done in shameful secret alone again.
