I've never done it with multiple partners at the same time, and this would be no place for me to try it out. So I'm going with one per day, devoting my utmost efforts one on one. I'd do Bonnie, McKenzie, and finish up with Val. I'd abstain for a week ahead of time to build max splooge, and knock down at least a quart a day of pedialyte. Hey this is an awesome fantasy!
