Fucked my father in law with my husband’s approval

Alright so some background: I’m 38 and use to be in the sex industry as a high end sex worker during my early 20s, so suffice to say I’ve always been very sexual. Met my husband during my mid twenties and he was also very sexually open. Hence, we’ve had an open relationship for the longest time.

A few months back my father in law was diagnosed with stage 3 pancreatic cancer. It was quite the shock for all of us and there was a lot of sadness going around as he was very much loved by all. Once the news started to set in, my husband and I started talking about the things we could to make his days as comfortable and as pleasant as possible. During one night we were fooling around, and I suggested I fuck him. My husband found the idea incredibly hot and so what started as a hot suggestion turned into reality and I fucked him

Did I make a loving gesture or have we caused more trouble?
