Chapter Text
Commonly know as futanari due to their popularity in Japan, members of the so-called third sex are simultaneous hermaphrodites possessing both a vagina and penis. Formerly rare, the population of futanari has undergone an explosion for reasons science still does not understand and continues to grow/ With pheromones that make women extremely horny and a bottomless sexual appetite, futas are the ultimate girl-fuckers. As futanari go from a rare minority to commonplace, the world will change around them. We cannot yet say how what these changes will be, but they will be sexy and very sapphic.

This series will have exclusively futa/futa or futa/female scenes. Men exist in this world, but aren't the focus and won't appear except in passing.
Chapter Text
Futanari are indistinguishable from cis girls for a large portion of their lives, only identifiable with advanced genetics testing. It's not till their late teens that they grow their penises, almost always overnight. This is also when they start making pheromones and their libido skyrockets. This means most girls don't realize they're futas until they wake up one morning with a dick, a bottomless sexual appetite, and women falling over themselves to get their cocks. The first few days afterwards are often a haze of masturbating and fucking women until the new futa can get a routine going and her lust fades to manageable (but still high) levels.

Chapter Text
Futas produce only x-chromosome sperm and so while they can impregnate women, any child would only have x-chromosomes as well as a higher chance of being a futanari as well. However, seemingly as a counter to their high libidos, futa sperm is less effective, such that even basic over-the-counter birth control can keep you safe if a futa cums inside you. Now that futas are so much more common, most girls take that kind of birth control just to be safe. Futa pheromone blockers are only so effective after all, and you never know when you might find yourself getting fucked raw by a giant girldick.

That gets a lot of the basic worldbuilding necessities out of the way so I can open up the series to more personal scenes and some more worldbuilding to build on the bases of how futas work in this setting
Chapter Text
Futanari have long been popular in Japan, where they were historically seen as blessed by the gods. In fact, the word futanari originated in Japan. In contrast to many other cultures, where futanari were seen as deviants or cursed, they were celebrated in Japan. That hasn’t changed in modern times, when the futanari population has exploded. In fact, there are many Shinto shrines that have futanari Mikos who happily give blessings of sex to needy girlcocks.

Chapter Text
Clubs in this school need a teacher to act as a supervisor. Since there are 3 futanari students, we decided we wanted to make a futa club, where the three of us could come together for support and discussion on what life as a futanari is like. And, to be honest, so we have a place to fuck each other to relieve our lust without having to get all the monosex girls involved and take up their days. We weren’t sure if we could get a supervisor, but Ms. Ramirez practically jumped at the opportunity. She said some stuff about wanting to help us learn responsibility, but it turns out she’s just really into being fucked by futanari dick. None of us are complaining about it. She’s super hot and an amazing partner.

Happy Valentine’s day. I know you love to drink my cum, so I made some fresh for you. Don’t get any weird ideas, though, this is just your obligation gift. It’s not like I like you or anything…

Chapter Text
I tutted at my patient, a futa who had only recently grown her cock and was back in my office for pain again.
“How long has it been since you last ejaculated?”
She blushed at my bluntness and mumbled something about a few days.
I sighed. “We’ve been over this before. It’s not healthy for a futanari to keep from cuming for that long. You’re in pain because you’re backed up.”
“But it’s so embarrassing,” she said.
Such a sheltered girl. I have to help her. I pulled out a lubed-up pocket pussy I kep around for just such an occasion, took hold of her cock in one hand and slipped the toy onto her as she gasped. “You have to get used to it for your health. Ask the girls around you. I’m sure some of them will be happy to help a young futa like I am. They’ll probably go even further than me. Think of how good this feels and stop holding back for your own sake.”
As I spoke, my hand moved faster and faster, forcing the pocket pussy up and don over her twitching shaft. It wasn’t long before a shot of cum, big even for a futa, burst out of her cock and splattered over the wall with a moan of pleasure. The poor girl sat slumped in her chair, gasping, but her cock was still erect.
“Can you do that again?” she eventually got out.
Oh I wish. “Nope,” I said. “You know what you need to do. Before the day is over I expect you to find some cute girl and get that cock of yours in at least one of her holes. Just ask, you’d be surprised on how many of us would jump at the chance to fuck futa dick.”

Chapter Text
When I, a futanari, became a teacher, people thought I’d be fucking the girls in my class, but I vowed not to. I got into this job because I want to help the next generation excel, not for access to schoolgirl bodies, and I made a point of showing that by refraining from sex, even as so many girls tried to seduce me. Well one day, I had missed my morning masturbation, so I was already backed up and horny as one girl started showing off her cute little butt to me. The dam broke and I bent her over and fucked her horny pussy all through lunch. I felt bad about it afterwards, but got nothing but encouragement from my colleagues. I should have been fucking my students this whole time, this is heavenly.

Sometimes it can be annoying how good futa cum tastes to women. Once word got out that a futa works here, women wouldn’t stop ordering cum coffee from the secret menu. I spend most of my day with my dick out, ready to cum in a cup. It’s nice that I get paid to cum, but even a futa can’t make unlimited semen.

“Mom, I’m home!”
Before I even had a chance to respond, I felt the familiar sensation of my pants being pulled down and a giant penis entering my pussy. Ever since my daughter became a futa I’ve become her favorite cumdump.
“That’s right, mom,” she whispered in my ear. “You love your daughter’s huge cock, don’t you? You love being my cumdump.”
I couldn’t help it. “Yes!” I yelled out in pleasure. “Yes, I love being your cumdump! I love it when you fuck my dirty holes with your cock!”
It may be wrong, but I can’t go back now. I dare any woman to live with a futa with hormones like hers and not become her cumdump. I’m my daughter’s slut now and I love it.

Oh no, not again! I hate getting random boners, especially at work. And I can’t hide anything under this skirt! Where’s that cute new intern? I need to go facefuck her until my stupid girlcock goes down again. If not, all the women in the office will be coming for my cock and I’ll get in trouble again.

Holy shit, that cute lady sleeping across from me on the train fell asleep and she’s got a serious sleep boner going on. Wait, is she… holy shit, she had a wet dream! Now she’s awake and she’s so embarrassed, it’s adorable. She’s still hard too, maybe I’ll offer her my pussy to use since she seems upset.

Apparently Gelbooru decided to change how they host their images. Since that's where most of my pictures are hosted, I need to go through and fix most of them individually. I'm working on the longer caption series first. This'll take a while, so hang in there.

I let my friend try using my cum as a seasoning once and now she’s addicted. I know lots of girls love the taste of futa cum, but this is a bit much. Now she’s here jerking me off over the shitty school lunches. I’m so going to fuck her after school today. She owes me.

This futanari bikini bottom was such a rip-off! It stops covering my cock the second it starts to get hard. Now all the women on the beach are giving me that look that says I’m not getting out of here without fucking a lot of them.

No, I didn’t hire this hottie because of her big futa dick. I didn’t even know until after she was here. But once I found out, I told her that if she ever needs some release at work, to come to me. It took a while, but she eventually showed up to my office with a tent in her skirt, all shy and cute. Since then, he’ve fucked more and more. At this point I may as well put “fuck my holes with your giant girlcock” in her job description.

I’m a personal trainer helping people get fit. Most of the time I can keep things perfectly professional, but this new client… Talk about a total MILF! She really gets my girlcock hard whenever she shows up in her tight workout clothes, showing off that incredible body of hers. Well one day I couldn’t hide it anymore and popped a boner in front of her. Turns out, she was deliberately trying to seduce me this whole time. Now I think it’s safe to add awesome sex to the schedule every time she shows up.

My all-girl’s school has most of the futas in the city as students. To deal with dozens of horny girls with dicks in the same place, the school started a system where some of us non-futas are assigned to assist the futas satisfy their cocks. That way, the futas focus on a few girls at a time and let the rest go about their normal days. It’s my week now and I was assigned to be in charge of blowjobs. So far I’ve spent a few hours with girlcocks shoved down my throat. Holy shit, this is amazing, I can’t believe I was nervous about being a futa cumdump

This casino is known for its use of sexy women in playboy bunny suits to bring in business. When the first futanari bunny girl was hired, some people were worried that a girlcock bulge would turn guys off from coming in. Turns out, having a horny futanari pin a bunnygirl to a table and fuck her in front of the whole casino was a big hit. Guys love seeing two chicks fuck, even if one of them has a dick. Now she puts on nightly futa sex shows and fucks a different bunnygirl each night.

OMG! I’ve never met another futanari before! Yeah, it’s just been me, which does mean I get my pick of cute girls to fuck, but I’ve totally wanted to meet another futa for a while! Can you do me a favor? I’ve fucked so many girls but I’ve never been fucked and I’m dying to know what it feels like. Come on, use your fat girlcock on my virgin pussy!

“What are you doing?” I asked as my girlfriend pulled my cock out of my shorts.
“What?” she asked with fake innocence. “You got a snack so it’s only fair I get to suck on something too.”
“But we’re in public! It’s a festival!”
“Good,” she said. “Maybe some other hot babes will be attracted to your girlcock and we can have a futa orgy.”
My retort died as she slid her lips down my shaft, drowned out by pleasure. I don’t know what’s going to happen, but now I just have to go along for the ride. I can’t say no to her mouth.

How did a plain, boring, nobody of a futa become friends with a popular girl like her? It turns out she’s a big foodie and when she heard that futa cum is a delicacy, she decided she needed to try it. I’m the only futanari around, so she came to me. We’ve made a nice partnership. She can’t get enough of my fresh cum in her food and seeing a cute girl slurp down my semen gets me so horny I can’t help but fuck her.

Yeah, the images are broken again. AO3 seems to have issues with Gelbooru links. If you right click the broken images, you can get the address and see them that way. In the mean time, I'm probably going to stop using Gelbooru links and host all the images on Pixhost. Between work and me being very easily bored, that might take a little while. I'll keep uploading in the meantime, I actually have a new caption ready to go tomorrow morning and I'll be using Pixhost going forward

I don’t see why my penis has to be the center of the cheerleading routine. I know everyone says that seeing a massive, cumming girlcock bouncing to the beat gives the girls in the sports teams some extra motivation, but it’s embarrassing to see everyone staring at me, or rather at my cock. On the other hand, I do get jumped by lots of horny girls every time I perform. Hmm, maybe it’s worth it.

We’ve been friends since childhood. Back then, we made these bracelets together to symbolize how we’d be best friends forever. Once she grew her cock, she was so shy and panicked. I remembered the bracelets, remembered our promise, and I knew I had to be there for her. I offered myself up as her personal cumdump, here to let her use her cock on whenever she needs. I’ll do anything fro my best friend and getting fucked by futa dick every day is an added bonus

It's been a while but I'm hoping I can start posing more frequently. I went through a bought of both depression and work being crazy busy that did not leave me in a good headspace to write. Things are looking up though.
