My wife is having an affair with our neighbour

I should have picked up the signs before, but you know what its like, you just think everything is ok. Well, turns out everything is not, 'OK'! Seems my loving wife has been fucking the next door neighbour every time I go out of town. Of course, he is younger than her, and can fuck her stupid till she can't walk properly. That would explain why I keep seeing her sitting down a little uncomfortably. Anyway, you may ask, what am I going to do about it? Nothing! That's right, nothing. What neither of them know is that I am fucking his mother and while my wife thinks she has me fooled what she doesn't know is that the mother is a much better fuck than she is. So, not going to spoil the party! But, don't tell my wife ha ha!
