When Evil overlaps Good

When lust overpowers logic and morals...

I have peculiar tastes. I like to be gagged and choked and fucked six ways to Sundays until I could not orgasm anymore.

Getting tired of boring missionarys, I decided to give myself to Hades, and be his personal fuck toy.
However, what I don't realize is that; one taste can lead to a grave addiction.

Who knows that sex with the devil can be quite addicting?
