SiF gets a letter from a listener who's recently experienced her first group sex play and learned later that her husband snuck in a little PiV action while she was rounding up a double-ended dildo in the other room. She had a great time but is hurt by the fact that he broke the rules.
She writes,

Hey Kidder -- My husband and I had two very hot and
sexy single friends over last night. We all ended up naked in the
kitchen and fooling around...and that leads me to my question. I'll
break it down like this: The good news is that I finally got some girl
on girl action. It was awesome! I got to play with boobies, finger her
and eat box! :) I thought the whole thing went swimmingly well until my
husband told me The Bad News: my he had some P.I.V. action with the
other girl, which happened on the staircase while going to get a toy. I
was not there. It was minimal, in and out 2 times before they recovered
their senses and stopped. We were all pretty tipsy, and we didn't
discuss boundaries before our impromptu sexytime. That may make me a
very irresponsible SIF listener, but be that as it is...I feel SO
betrayed and hurt. Alan KNOWS my boundaries with PIV and also with this
particular woman. We've spent 9 years rebuilding the trust he broke when
he cheated on me before we were married. I also feel like he ruined a
perfectly INCREDIBLE, hot sexy encounter with our two friends. As you
know, I've never done that before, it was a huge and much anticipated
experience for me, and I think it rocked except for my seriously hurt
feelings and his whackadooooo bullshit PIV action. :( Anyway, I'm pretty
confused and I'm trying to be cool about it. He knows how I feel.

Thanks for listening, any advice from you, Jade, or anyone else would be helpful and welcome.

ps--Salt
on the wound: I surprised him and got an iud for xmas so we could be
fluid bonded, and now I want him to get screened for STIs, because the
PIV was not protected. I'm so bummed. What is the incubation period?

pps--It's nice to hear you dropping the F-bomb again :)
