As my wife's interest in sex has faded over time I have become hornier for sex with guys, who happen to be in similar situations with their wives. I told her she basically gives me not much alternative. I still have needs,
Our friend had done it to me before , but it was my wife who shamed me into returning the favor. A little intimidating at first, but quickly turned into showing off. No gag reflex for me and when she saw me take our friends cock all the way down my throat, she was impressed. She has been a big part the whole experience.
