[Futa4F/GM] A clinical trial gone wrong made me grow a cock and it's out of control!
I remember every moment of that day vividly. It had been a Saturday, early in my second term of college. I'd signed up for a clinical trial that paid out pretty nice gift cards to participants. No harm in it - they'd just said they wanted a control group or something, to see if there were any side effects. I hadn't paid much attention - it had to be safe if they were doing a clinical trial, right? Plus I was just a bright-eyed college student who could use a little extra money.
When I'd arrived, they'd let me know the nature of the drug - to let women temporarily grow a penis for sexual purposes. They wanted to make sure their theorized effects on women in good health who didn't take other meds were accurate - and, most importantly, that it was temporary. Easy enough, the grad student helping me out was a cutie with a huge rack, and I'd always been curious about having a dick, even if only temporarily.
The next part is what really stuck with me. No sooner did I swallow the pill than did I feel my pussy heat up and flush, soaking itself instantly. She had said arousal was to be expected, but this was insane. My eyes flocked around looking for the most dick-like thing to shove in my cunt. She asked how I felt, if it felt okay, but I could barely hear her through the blood rushing in my ears, just nodding as I couldn't stop myself from staring at her rack.
Then I felt the *other* sensation. It was unlike anything else, a feeling of intense pressure in my pubic area before a sudden release... and the feeling of something growing. I didn't realize anything was wrong at first before I saw the assistant's expression, and realized that I had a cock. It was big, too. Way bigger than any dick I'd seen in porn or in real life by at least a good couple of inches, clearly thicker, already leaking precum so thick that it might as well have been cum from a normal man. After the initial shock wore off, the girl had been calm. Or tried to be. "Well, that's good to know," she'd said, smiling. "We might ask you a few more questions. That's... *much* larger than we expected. Don't worry. It goes away in a couple of hours." I couldn't figure out if she was flustered because something had gone wrong, or she thought the giant cock was hot. Either way, I could barely hold myself back from pushing her down and trying to shove it inside her.
As you might have figured out, it did *not* go away in a couple of hours. Or a couple of days, or months. In fact, it's been two years and I've still got a gigantic cock. Since then, I've learned a lot of its quirks. The dick kind of has a mind of its own. It gets hard when I get turned on like a normal dick, but it'll get hard at random, which is immediately followed by some of the most intense horniness I've ever felt. Horniness isn't even the word, it's like a *need* that just takes me over entirely. I could probably describe it as lifestyle ruining if I wanted to, the way it takes over my mind basically whenever it wants. No matter how many loads I milk out of it, it's always spurting the thickest semen I've ever seen, in quantities that could probably rip open a condom... if I could even fit one on the thing. I'm still figuring out how to deal with it, but at least claiming "permanent mental distress" got me a ludicrous amount of compensation. Way better than the stupid gift card.

Hiya! So, would love to chat ideas for this one! I left the exact scenes and story a little up in the air. this is the sort of thing where I'd love to view this as a jumping off point for us to brainstorm and come up with something that suits us perfectly! I left sizes up for debate, but do let me know your preferred sizes for cocks and balls!
One thing I'd love to chat about is the idea of the dick having a mind of its own and(in a way) controlling our lovely futa's mind when it gets excited, and what that looks like. Does she just get really horny, or does she get a little more insistent/needy? Maybe she gets pushier with what she wants, or rather what her dick wants? I'd be willing to explore things all the way to dub-con/non-con with the right partner, but totally not necessary! Further on that topic, how do we want the dick to control her? Does it just get hard at the wrong time, or is it actually a voice in her head trying to get her to do whatever it wants?
Other kinks I'd love to explore are tightness/struggling with insertions), breeding, pregnancy(maybe this dick just makes it *really* hard to pull out), and many others!
I'll post my full kinklist below, but please do let me know any you like/dislike, or ones you might like to add! I also have refs, so please ask if you'd like to see them!
What with Reddit axing PMs, my platform of choice is Discord. Shoot me a message here and we can chat a bit and see if we click, and go from there! I usually aim for at least 2 paragraphs per response, and would like similar from you. I'm not a stickler for word count or anything, but as long as we have enough details to keep us happy and I'm getting ideas to work with, I'm happy!
My kinks! Big/extra big cocks and balls, pregnancy, impregnation, incest, bulges, distension, tons of cum, cum inflation, spanking, public sex/teasing, freeuse, name calling(usually sweet/cute names), cock worship, non-penetrative sex(titjobs, handjobs, etc.), lactating, tight clothes, teasing, casual sex/nudity, dirty/crude talk, edging, sub futas, soft doms
Hope to hear from you!
