Demon Tentacles Claim You Inside Out (Patreon)

A succubus shapeshifter sheds her human guise and transforms into a writhing tentacle monster, using her eldritch form to claim your body in a possession that borders on the horrific. By the end of the audio, you are utterly reshaped inside and out as the demons tentacles spread like a second skin, leaving you unable to tell where your own flesh ends and her monstrous form begins.
