Zalnarya sat down at the edge of the huge bed, her long hair flowing down on the sheets. She positioned herself very close, and presented her massive, yet very feminine body to you. The female demon seemed to be covered in oil (or was it just sweat?), she glistened seductively in the dimmed down light of the room.
Then she opened her legs, making sure you noticed her very moist labia. Her terrible, teethy grin, and her muscular frame made this feel as if you are about to mate with the most dangerous predatory animal you ever encountered.
Note:
I made some heavy adjustments to her boobs, head and hips, to match her better to the previous"demon girlfriend" image. I love that combination of her scary rictus-like grin and voluptuous body. And yes, I'm a fan of the "Liquify"-tool in Photoshop for quick anatomical changes. So handy.
