My wife has cheated since we first met. She has a serious weakness for any guy who pays her attention and compliments her, if they are persistent she will eventually start fucking them. Then eventually she either slips up or tells me. Once I know, she says the excitement is gone and she stops until she finds the next one.
There has been a bit of a dry spell for about a year but that all changed. Last week she went on vacation with two friends. A few days after coming home she had a few drinks and admitted that she stayed with a man in his hotel room for two of the three nights she was there. Normally that would be enough to keep my dick hard for days but this time was different. She keeps telling me how much bigger his cock was, how much more he came more than me, and that he could go longer and cum multiple times, something I can't do anymore.
The other night while fucking she talked about how big and hard he was, how full he made her feel, and how good his cum tasted. The more she bragged about how much better his dick was than mine and the more she told me how he fucked her so much harder than I ever do the more I got excited. So much so that I have convinced her to find a regular boyfriend who is hung with 9 inches.
