[M4F] Taking a 'sexual compatibility test' with your best friend is all just fun and games right?
This post is: OPEN
PartnerMatch was the name of the app taking the internet by storm. The name made it sound like it was just some new dating app; one of dozens, forgettable. And yet it had quietly dropped onto the app stores and spread by nothing but word of mouth. People posted about it on the internet, incredulous about the results, driving traffic to the app. Videos started popping up on Youtube of people doing the test in the app and getting quite shocking results. It had slowly but surely taken over the online discourse, with people praising its predictive abilities and questioning the results in equal measure.
So what does it actually do? Put simply, it takes some mundane information about you and uses the magic of 'AI' to find the perfect sexual partner for you among all the people who've taken the test. It asks you your name, birthday, height, favourite foods, movies you like or dislike, when you last ate cake, what the colour green smells like to you, what sort of music makes your mind vibrate... Questions that sound either completely unrelated to one's sex life or plain absurd. Somehow from that seemingly useless data it produces a match, and nobody knows how. The people who are singing its praises don't seem to care though, since there is a startling accuracy to its findings: It's brought people together who have always quietly had crushes on one another. It revealed the hidden kinks of partners in dead bedrooms, revitalising their sex life. It's also resulted in tons of hookups and new relationships starting, using the 'contact my match' feature. There is still plenty of doubt around the veracity of these stories. It could all be marketing after all. Still, the volume of testimonials at least indicated there's something to the app.
That's why me and my best friend Samantha are currently installing the app on our phones. We were hanging out and got to the topic of that new app everyone's talking about. "Why don't we just install it and see what happens? I'd like to see what kinda nonsense the app claims about me." I said jokingly. Samantha laughed and agreed, convinced it would all be just hype and nothing more. The app downloaded quickly, and once it opened we were presented with a simple interface. Questions and text boxes to fill in our info, on a plain background. It asked me my name, the name of my first pet, whether I knew how to ride a bike, what kind of pancake I liked best... nonsense really. I laughed at each new question, feeling less like I was taking a test about my sexual preferences and more like being interviewed by a 5 year old.
"How the hell do they find your perfect partner with this info?"
"I know right, ridiculous. Let's just see what this dumb bot spits out."
The test took about 15 minutes, and when we finished a popup informed us the matching process could take up to another 15 minutes. I put my phone down and sighed. "Well, looks like we'll have to wait. I'll go grab us some drinks and we'll..."

I hadn't even gotten up off the couch we were relaxing on before our phones pinged, simultaneously. We each picked ours up with renewed excitement. Did it get a match that quickly? How?
At first surprise, then shock, then curiosity. The result it displayed for us was... each other. I was her match, she was mine. I stared in disbelief at the results screen:
Strong match!
+++100% mutual body type preference, ++very high kink compatibility, ++similar sexual endurance, +++located near one another, ++already familiar with one another.
Below that was a whole slew of different specific factors that made Samantha my perfect match. From the big and obvious like her huge bust, to details like the texture of her tongue, or the way she shaved her pubic hair.
We looked up from the screen and shared a look. Many different emotions swirled in our eyes as we tried to find the words. I was suddenly looking at my long best friend in a very different light. Sure, she was hot, and my type, but is she really into all the same stuff that I'm into. 100% body type preference too? Not like, 95% or something? She is my perfect match? I could hardly believe it at first, but if I stopped thinking of her as just a friend, I could feel a part of my brain light up like fireworks.
After a long and awkward beat of silence, Samantha was the first to say something. "...is... is your dick really that girthy?". She was blushing a deep red as she said it, and so was I. I couldn't deny it, but I also couldn't confirm it. For some reason, I just blurted out "...w-w-want to see... for yourself?"

Hey there, thanks for reading that big ol' prompt! I'll keep things short from here. I'm looking for someone to play this friends to fwb/lovers plot. I heavily prefer this be a long term thing, where the above is just the start of a new relationship. We'd use the info granted by the app to fulfil each other's greatest sexual desires, maybe even the things we couldn't tell anyone else about. This could also be a romantic thing, with the sex leading to a genuinely happy relationship outside the bedroom. Perhaps there's a catch, like the app requiring us to do increasingly racy things to unlock more information, or requiring we pay for using the app with recordings of our wild mating sessions. I'm open to swapping ideas back and forth, and appreciate creative partners!
Part of the deal with this plot is that I'm willing to leave a lot of the details of my character up to you. I can fill in any blanks myself, but I want to play your ideal guy. The guy that's been your friend for the longest time, so you've forgotten how much he makes your heart, and pussy, ache. In return, I'd like it if you'd do the same for me. If you're open to it I have some drawn/hentai refs you could play, but character descriptions work for me too.
I'm located in the Amsterdam timezone, I can write about 2-4 paragraphs per reply on average, I prefer writing in 1st person but don't mind 3rd, and if you also prefer using Discord then please mention that in your introduction. You can find my kinklist below. I'm a switch, but this list doesn't fully reflect my sub side, so ask about that if you're interested. I'd also like you to send a (short) kinklist in your first message.
Hope to see you soon!
