The oily slime-covered sex demon.

With her oiled flesh still sliding against the dark tar-like substance, she had a slime dripping from her breasts and thighs. Her eyes were yellow reptilian eyes, and she had a round perky B cup breast that oozed with pale liquid. The young adult female protagonist was having sex with a dark mottled beast that exuded thick coagulated splotches of tentacle-like material all over its body. She had oily black hair spread all over her head, framing her face in clumps of textured strands.
