A friend of us was sleeping in our house after a night in some pubs. My wife wanted to have some sex with me, but I was a little bit to drunk. She was asking me, ift it's o.k. for me, if she go downstairs to our friend for some minutes. A half our later I went carefully to the room downstairs, opened it only a little bit and got a look on my well fucked wife. It was so hot that I was playing with myself. Two weeks later she told me, that she wanted to get pregnant from him. I was really shocked and wanted to stop her, bit it was not possible. Nearly four weeks later (she was meeting him twice a week and was always full of his semen and for me it was only allowed to cum in her ass) she was pregnant.
