My wife has always been a hotwife.  I have enjoyed sharing her in mfm, ffm and mfmf fun but in addition she has a couple of other lovers she meets alone.  I have also got a FWB. We are happy with this situation and have been married over 10 years.  Recently she has brought her two lovers to our home (not at same time), not when i have been here.  She has now asked if i would join them, not to fuck but just to watch and to suck her lovers hard.  This is a change and would be the first time i'd not be participating.  If feels it is moving from a hotwife situation to a cuck situation.  I am 100% straight ,never touched another guy's  cock in my life.
