The Futa Experiment: A Descent into Euphoric Depravity

The flickering neon sign above the dilapidated motel cast a sickly green glow on the flyer clutched in my hand. “Seeking Strong Volunteers! High Pay! Excellent Benefits!” It was a lifeline, a glimmer of hope amidst the crushing despair that had become our reality. Job prospects were nonexistent, and the meager savings we had scraped together were dwindling faster than a politician’s morals.

The ad itself was cryptic, mentioning a “cutting-edge research facility” located somewhere on the outskirts of the city. Details were scarce, but desperation fueled my curiosity. I knew I had to take a chance, and after a tense discussion, I convinced Sarah, my ever-supportive girlfriend, to accompany me.

The journey to the facility was a blur of dust-choked roads and desolate landscapes. The imposing steel and glass complex that greeted us seemed at odds with its desolate surroundings. Inside, a pristine lobby staffed by immaculately dressed women ushered us through a battery of tests and interviews. Finally, we were led to a conference room where a charismatic yet unsettlingly youthful Dr. Anya Petrova awaited us.

Dr. Petrova’s explanation was as shocking as it was intriguing. The Torian Corporation, the shadowy entity funding the research, was attempting to create a new human race – one imbued with superior strength, intellect, and, most curiously, a unique biological modification. These individuals, exclusively female and possessing both male and female genitalia, were what Dr. Petrova termed “Futas.”

The crux of the experiment, however, lay in a peculiar side effect. The Futas’ sexual fluids were laced with a potent, psychoactive compound that induced euphoria and a fervent desire for further exposure. Dr. Petrova, with a disconcertingly seductive smile, explained this was where we came in. Our job, as “compatibility specialists,” would be to ensure the Futas’ emotional and physical well-being – a euphemism for becoming their dedicated sexual partners, I quickly realized.

The ethical implications were a tangled mess. Were we becoming lab rats ourselves, pawns in a twisted scientific game? Yet, the promise of financial security and the allure of a life unlike anything we’d ever imagined was undeniably tempting. Sarah, ever the pragmatist, saw it as a means to an end. We could endure a few years of… unconventional labor, secure our future, and then walk away.

But the allure of the Futas themselves was another factor entirely. The facility housed a stunning array of women, their bodies sculpted to perfection, their gazes both alluring and strangely predatory. The knowledge that their touch could send me spiraling into a blissful oblivion was both terrifying and exhilarating.

The Futa Experiment promises a thrilling descent into a world of scientific taboo, erotic indulgence, and the blurring of moral boundaries. Do we succumb to the addictive pleasure offered by the Futas and risk becoming mere thralls to their biology? Or can we navigate this twisted utopia, secure our freedom, and perhaps even find a love that transcends the boundaries of human sexuality? The choice is yours.

Developer Notes

Developer: Torian Blog – Patreon – Subscribestar

Hello everyone and welcome.
This is a semi-demo/alpha. There is a lot more content than a normal demo or 0.1 and I have been working on it for about 4-5 months, I have included a cheat option in the Player room, using this will mean getting to some of the scenes faster if you choose to allow your girlfriend to stay. (Not recommended unless you just want to see scenes faster). I have playtested quite a lot and hoping that there shouldn’t be too many bugs left, but there is about 13k lines of code in total…so might have missed some.

It is an unconventional VN. It is non-linear and has a gameplay loop. You must do tasks for the girls, as their lust increases they may ask for sexual favours. You must keep the majority of the girls happy as once per week they will decide if they want you to stay.

If you choose to allow your girlfriend to stay she will also be working and will grow closer with the girls. It is not instant and will take time as they slowly try to convince her. You will have the option to allow the girls to sleep with her, which will increase the chances of sexual encounters.

The game contains a number of still scenes and semi-animated scenes. Around 50-60 scenes in total.
Just under 30k words (29,978)
Futa on Female
Futa on Male (Optional)
NTR (Optional)
