Wife loves her young boyfriend

My wife is 51 and has a 22yr old boyfriend and they are falling in love with eachother.
That is ok by me because she loves me as her husband differently than her boyfriend.
The sex they have is so wonderful to watch and I love cleaning her up and sloppy seconds after he is done.
It is so much hotter when theey cross this line and develop emotional feelings for each other too!! CW
