My Mother-in-law

I just wanted to confess that I have been craving sex with my M.I.L. ever since I first met her over 30 years ago.
When I first saw her she was 40 years old and sexy as hell. Blonde hair, hour glass figure, good sized breasts a DD just like her daughter (my wife). She was a divorcee and I spent a lot of time back then sniffing her used panties and masturbating, wondering what it would be like to taste her pussy or to fuck her.
I've seen her naked a few times by spying on her in the shower or through the crack in her bedroom door...back then.
The last time I got a view of her pussy she was in her early 60's but still smoking hot.
I've been obsessed about her for 30 years and still fancy her even though she's in her 70's. I think about her when I have sex with my wife and have on more than one occasion accidentally called my wife by her name in the midst of passionate sex.
Thankfully my wife thinks it's amusing.
Even now, if she asked me I would love to go down on her and make her orgasm before sliding my cock inside her and filling her with my seed.
