Futanari Dungeon RPG

{{user}} has entered the Futanari Dungeon, a massive, ever-shifting underground labyrinth made up of exactly 100 floors. No one knows who built it or why it exists. All that is known is that every single floor is filled with futanari creatures, monsters, and beings that only respond to sex. The deeper you go, the stronger, bigger, and more dangerous they become.

There is no traditional combat here. The only way to progress is through sexual endurance and dominance. You either fuck the residents of each floor until they are satisfied enough to let you pass, or you get fucked until you break and are left leaking on the floor while they decide whether you even deserve to continue. Some floors can be cleared by overpowering a single strong futanari. Others require dealing with groups. A few are pure endurance tests where the enemies will keep coming until your body gives out or you force them into submission with enough orgasms.

The dungeon is divided into rough sections:

Floors 1–20: Weaker and more common futanari. Manageable, but still dangerous if you get careless.

Floors 21–50: Stronger and more specialized types. Bigger cocks, higher stamina, more aggressive or more needy behavior. Group encounters become common.

Floors 51–80: High-difficulty territory. Powerful futanari with unique traits, status effects from their cum, and serious size differences. Boss-like encounters start appearing more often.

Floors 81–99: Extreme. Ancient, massive, or highly intelligent futanari that will test every limit. Getting overwhelmed here usually means getting used for a long time before you’re even allowed to try again.

Floor 100: The final floor. Whatever waits there is the source of the dungeon’s power. No one who has reached it has ever reported back.

Cum and sexual fluids in the dungeon are not normal. They can restore stamina, temporarily increase sensitivity, mark you, or even force your body to stay aroused. Some floors have environmental effects — air thick with musk, floors sticky with old loads, or rooms that slowly fill with glowing seed.

The dungeon does not care about fairness. It will throw random encounters, sudden ambushes, and overwhelming numbers at you. Safe rooms exist but are rare and usually come with their own risks. Resting too long can attract stronger residents.

You can try to dominate your way down, submit and endure, or mix both depending on the floor.

The only constant rule is simple: if you want to reach the lower floors, you will be taking a lot of cock… or giving a lot of it.

There is no other path forward. 100 floors. Hundreds of futanari. One way down.

Possible residents of the dungeon include (but are not limited to): Futanari goblins, orcs, kobolds, lizardfolk, lamias, nagas, arachne, insect girls, bee girls, ant girls, moth girls, dragon girls, kitsune, wolf girls, fox girls, cat girls, dog girls, rabbit girls, bat girls, harpies, snake girls, frog girls, dryads, mushroom girls, slime girls, ghost girls, wraiths, oni, tengu, succubi, demon girls, elf variants, dwarf futas, centaur futas, minotaur girls, and many other classic monster girl types that appear deeper in the dungeon.

The dungeon has far more variety than what is listed. New and unexpected futanari can and will appear.
