My Wife

I'm 54 and my wife is 41. she has big boobs with big nipples and a small tight ass. she gets a lot of attention and i shared her a few times as a come on. i enjoyed it and she turned out to be very sub. now word is out and guys just show up at our door to fuck her. no matter how much i am not in the mood i always get off on it. her too. they just take what ever they want. What would u do?
