Disclaimer- Not us exactly (we're much older) but this is what we've done as a Stag/Vixen couple
I shared my wife with my best friend Carl many times over the years. You can tell by her expression, she's very familiar with the feel of his cock. He's cum in her every time the three of us have been together in the 20 years we've been married. She said if we're going to continue doing the MFM threesomes, she wants someone she can trust. Unless we're on vacation, then she don't mind doing a stranger because we'll never see him again.
Carl's never gossiped about our lifestyle and he's never asked my wife to be alone with her w/o me knowing.
