I used to masturbate to pictures of my ex wife. My favorite was one of her in her wedding gown, she looked so beautiful. She was a real bitch though, and I couldn't stand her, except to masturbate to her pictures. It was a strange sensation; to cum over and over again to someone I hated.
I developed these masturbation fantasies where I would go to her house and she would answer the door in sexy clothing. I would go in, and before long I had my face buried in her sweet, hairy, juicy cunt. I would suck on her clit until she came, just like when we were first together. Then I would cum and forget about the whole thing until I got one of her pictures out again. Maybe the one where she is in the bathing suit showing those gorgeous thighs.
