Fleshcult

Fleshcult is a text-based RPG where you play a sex demon: an incubus or succubus. You lurk on the margins of an unsuspecting city, seducing mortals into your underground lair. You're a shape-shifter, transforming your body and the bodies of your minions.

• You pick the kinks: As you play the game, you opt into the fetishes that you want to see.
• Play whichever gender you want, and play with the genders you want (including transgender characters).
• Meet goths, pornstars, house-husbands, nurses, bodybuilders, and more. Find temptations that they cannot resist.
• It's text based, but it's not a visual novel. You're continually involved, making decisions.
• Corrupt your body with over 65 different transformations, body mods, and clothing items.
• Build your lair. Snare intruders in a variety of traps.

Fleshcult for Steam is a rerelease of the 2014 web game with some new content, chiefly the long awaited Tome of Infestation.
