Threesome rules

*Guys, climax in your wife. Unless she specifically says ahead of time she wants to to finish in/on the other girl.

*Plenty of fresh towels. And clean that bathroom.

*Babysitters.

*cellphones off

*condoms on insertables, or different toys for each person

*don't get sloppy drunk

*It never hurts to be polite

"may I lick your butt?"
"Of course you may, thank you for asking."

*IMHO 3-somes work best if it can be decided who is going to be the "center of attention", then have the other two working in tandem on the same person. Work in shifts otherwise somebody's the 3rd wheel thats always getting jammed in the wrong place. Your gonna have a bad time.

*In a MFM 3-way make sure M1 and M2 establish their own boundaries before anything gets started. If M2 is expecting a reach-around and M1 isn't comfortable taking his socks off around around M2 you're gonna have a bad time.

*co-workers make awful 3rd persons

*Guys, refrain from cornball porno lines

"Ladies, theres enough pork-sword for everyone!"
", I knew it was my lucky day."
"Aww-yeah.... come to papa."
"I'm getting to old for this sh**."
