快楽恥帯 －謎の性物に汚された街－

The ashen remains of Earth's surface was bleak, hopeless. It's our world now.

But some of us kept living. Only the young women.
Perhaps living is the wrong word. We were alive.
We survive as sex slaves for the EBEs...

There's no semblance of humanity left in Tokyo.

In one day, the streets were transformed into a teeming beltway of sexual training. This is the Pleasure-Shame Zone.

*** EBEs, fornicating r*pe aliens!
Heroines have been suddenly captured and deflowered.
Their only hope is to endure with sloven, survivalist submission...

*** Slime, insectia, tentaclusters, breeders and humanoids
Plus futanari lesbians, sexual insanity forcing climax after juicy
climax, so many situations!

*** Humanity's downfall told from heroine's POV!
Experience the terror, the lust, the the pleasure.
Plummet despairing into the alien abyss of HOT F*CK.
