How do you keep from losing her?

What should I do?

My wife is staying out for a second night with her lover. She can't get enough of him and she has left me at our house with her cum stained panties from last night. It's 1am and I've spent the last hour licking the dried spunk of the crotch, whilst wanking myself silly thinking about what he's doing to her tonight.

She knows I'm turned on by her infidelity, at the begining she used to come home late and make me lick her cum filled pussy and I couldn't get enough of it. She would ask if I could taste him and would squeeze out his his cum onto my face, for me to lick it up. At first it turned her on to see me like this, she became dominant and would instruct me to lick every last drop and if I was lucky, I was then allowed to fuck her. But she stopped all this about three months ago and she will not let me fuck her anymore. He has stretched her with his cock which she told me was much bigger than mine. She always did get very wet when turned on but my cock just doesn't do anything for her now and I could even feel the difference when I was inside her.

I now know that I'm losing her completly to him and there's nothing I can do about it. It's an agony and an extasy. I love her so much but I think my reaction to finding out about her lover was my downfall. The thoughts of the two of them in my head just turned me on so much. I am cuckold. I had no idea that I would end up like this. Part of me so wants to turn the clock back but the other part longs to see her on her back with her lover plunging his cock deep inside her and spewing his hot cum into her pussy.

I can't wait till tomorrow evening when I will look in her laundry for the panties she is wearing this evening, hoping to see the cum stains, then putting them to my face, tasting the remnants of there sexual joining, whilst I patheticaly wank myself off. How can I keep from losing her altogether?
