It hasn't appeared in the "voting" page yet, but here's my idea.
The title sums it up: TrainHorny. I've seen TrigArousal and I thought that was cool... hell, I wrote my own Virtual Hypnotist script for it. I like it. But I know some people would probably like to take it further. So, this file causes the listener to be horny and aroused 24/7.
Now, this file would have two versions: One allows people to not be aroused when it would be inconvenient (like the men's locker room) but still be horny. The other one is just the full, 24/7/365 horny and aroused all the time.
What do you think?
