I have just run into an ex-lover. I call him an ex-lover because we didn't actually date much just had sex in the office, in the park, on a ferry. Just seeing him has reignited my libido because all I can think about all day is fucking him.

Everything is sexual to me right now - I masturbated on the train the other day (there was only one guy in the carriage several seats ahead with his back to me), I masturbate in the bathroom at work, I glance my breasts on men's arms, I stroke my breasts in public pretending to reach across my shoulder, I'm even fantasising about having sex with a stranger - but I know how dangerous that would be.

The reason I'm masturbating so much is that I'm in a strong relationship. My partner doesn't know about my chance encounter with my ex-lover, but my partner is sure reaping the benefits because we're having wall to wall sex. But as soon as I leave the house I'm horny again and I'll go off to the bathroom at work and masturbate, then at night I have a hot shower and rub my breasts, then go to bed and have sex with my partner. (We're having sex about 4-5 times a week right now)

I don't always think of the other guy while I'm having sex with my partner but sometimes just to push me over the edge to cum, I close my eyes and remember him doing me from behind in the office.
