Threesome idea.

This may or may not be anything new, but was wondering if anyone's ever posted for a private threesome? I've done RP's where I've played up to 3 characters at a time vs 1 per the other person, but instead of that... how about having three actual people? I don't really have an immediate idea for one, but just seeing if anyone's up for it.. then maybe we can figure out the idea when/if I find a couple people who'd be interested in playing along. And not even sure if I want to put out an APB out for two female or one male and one female. Guess I'll see if anyone bites.
