So would you let your partner play with Your sibling?
E.g You're a women, married to a man, would you let him fuck your sister (obv if she wanted to)
I love weird hyperthetical questions
It won't happen to me as I only have a brother and the hubby is straight. I have played with the hubby's sister with his blessing after being shocked by meeting her when we went to a club
Mixing Fab with real life? One of the key rules of engagement for us is that if either party unhappy for any reason you can leave and never see them again - no harm done. That's a lot harder if you see them in other contexts. Hence Family () , neighbours and work colleagues are out.
