I have licked my own out of my wife, have to be very horny though but having done that it gets me very hard and she is likely to get a second helping. She does enjoy it but is not keen for me to do it lol
A few weeks ago with a couple i have played with before several times. Hubby on his back and his wife straddling him, i knew they had tried it before and she had enjoyed it so I climbed on, the legs and where they go is the fun bit, but once you have worked that out its fine. Then i simply slid my cock along his and into his wife, fortunately im a big lad so definitely easier and she loved being stretched with 2 cocks in her pussy. You then have to decide if you thrust together or against each other one in one out. I have done DP with the first couple i ever met, me in her pussy and hubby in her ass, how we did not get thrown out of the hotel with the noise she made I do not know.
