Do what I did and most men who enjoy fucking a tight asshole. Find a young willing fuck buddy and screw the shit out of him. Believe me, because even though I'm married, there are plenty of young horny guys who want their assholes fucked by men like me. I know this because over the past eleven years I've been fucking various young men, one recently being my neighbors son.
I am an older married woman and I agree with the previous comment. Find yourself a fuck buddy and enjoy. If Your wife does not approve well keep it your secrete and enjoy it.
poster here: I may find a fuck buddy, but since that first guy at 15 I'm still more interested in women. But I guess I could look for either or both. I am hard now thinking of that 15 year old butt getting my cock in it for the first time.
