Sorry to break this to you, but unless you pay for it, a threesome does not mean you get to lie back and have your body licked up and down by two giggling hotties who think you're sexier than David Beckham. Just as with regular sex, a threesome means lots of give and a little less take. Offer your mouth, your hands, and your other parts for everyone else's use. Take gladly and be willing to return double what you receive. Generosity pays offthe more you offer to do, the more you'll have done to you.
