About six months ago, my husbands brother passed away and ever since we’ve regularly hosted his widowed sister in law to help alleviate what mental stresses we can.

Christmas Day she came over to open a few gifts and have Christmas dinner with us. After dinner we were having a couple of drinks and she asked us if we would consider letting her join us in the bedroom. I’ve been bi sexual my whole life, I’ve slept with both women and men, and had a blast each time, but I have never shared my husband with another woman and he has never shared me with another man.

We discussed in detail what she meant and she pretty much came out and said she would like penetrative sex with my husband. My husband looked at me as if expecting me to snap but was even more shocked when I said “we could try”. We didn’t end up doing anything that night but have talked heavily through text about it and have discussed the boundaries for each person involved. But my husband and I are worried if we follow through and something happens that it will hurt our friendship with her. How can we proceed and protect our friendship? Need advice never been in this position before.
