I am a married 47 year old woman. My husabnd and his best friend came back to our house last after they had been watching a game (basketball?) at a sports bar and had been drinking. My husband passed out on the couch later after having too much too drink. His friend came on to me after I came down to say good night in just a tshirt and panties. I don't know how it happened but I let him take my top off and I gave him a blowjob.

What if he tells my husband or bloackmails me? I don't know what to do....
