I’m not condoning what either of you did, but sometimes ignorance is bliss. What’s worrying is that you can’t stop thinking of him. I think you know in your own heart that if you have any chance of having a relationship with your sister in the future that you a) can’t revisit it b) you can’t stay the night at hers again and c) you can’t tell her what happened. You’re also married yourself, so you’ve cheated on your own hubby as well as betrayed your sister. However, it’s just terribly sad that you’ve chosen your sister’s husband to live out this fantasy with. You might have wanted to prove that you’re still a sexual being and attractive to men. Maybe it’s connected to going through the menopause in your 40s. I’m also 50 now and have been through the menopause, so what’s happening to me? This is weird for me as I have never been the sort of person to take matters into my own hands before or do anything impulsive.
Since then nothing has been mentioned about this by either of us – it’s as if it never happened – but I can’t stop thinking about him. We had fantastic sex and never said a word to each other. He got even more excited so then I dropped my dressing gown and joined him in the bed.
