Succubus

You, Venus Xana, are ready for some fun. You sigh in petty annoyance though, because instead of going and doing as you're supposed to, you have been called back to hell to check on the humans you've captured, instead of finding another soul to steal. It has become so common, and you have lived so long, stealing the souls of men (and some women, when the times call for it) when they cannot control their desire for you. You've mastered your abilities to give them just what they want, and you are now well respected within hell for your powers. None dare mess with you, as the demon lords certainly respect a demon who knows how to get things done. And with your powers of persuasion, it's not surprising that nobody gives you a second glance (except for the obvious reasons).

And, as always, they have nothing other than telling you that you have to go find someone to take their soul, and deceive them into having sex. Not too hard, considering how many people are always willing to try and have their way with you. Sometimes, you blend in, or sometimes you go the overt method and show men your true form. Hey, not like men wouldn't like to think that they've screwed a demon before! But still, why are they wasting their time telling what you were already going to do? Maybe it was just because they like taking out the time and looking at you.

So after reporting back to check on your stash, you return to the mortal world, and you head immediately to the nearest college campus. The center of sexual activities of young adults... prime targets, as their souls as strong as they grow into early adulthood. Full of vigor... and for that matter, not just their souls are vigorous. You've been known to even get groups this way, and you always try for the "big haul", as it looks far more impressive that way. So you wonder where to begin, figuring step one would be to find a willing subject.
