There are currently WAY more female oriented stories than male, so I am going to give some vague suggestions for some male stuff.

1. Modernish setting. A sahuagin/merman (should be more on the inhuman side) is captured at sea, and the people butcher/cook him alive.

2. A succubus/demoness preys on a man, and both sucks him dry/eats him.

3. A vampire awakens to find themselves locked within a coffin not their own, with holes purposefully made to allow the sun to burn them in a very gradual manner.

4. A maiden eating/raping dragon is dragged out of their lair after being defeated, and chained down to allow the peasantfolk whose daughters were lost to go to town on him.

5. An alien creature of some kind finds themselves being kept alive in a military base while he is subjected to all kinds of invasive tests and experiments.

6. A poacher gets their rocks off while gutting and castrating male tigers for chinese traditional medicine.
