There is nothing that goes together quite like a warm summer's day and cocktails on a Saturday afternoon. Except for a tipsy hot wife who is a more than a little horny for her husband's friend.
She is quite well aware that her husband totally approves, and wants things to keep going.
As the day progressed a good time was had by all, and although it didn't go all the way, their friend and his very large dick got the best BJ of his life as did her husband...
The next day she admitted to her husband that she loved it and had zero regrets. Quite the opposite. She told her husband that maybe next time it might be fun to have them both take turns having sex with her. That is if he would be okay with it.
OKAY with it? He had only been encouraging her for the last five years!
This is totally based on a true event. Early in our marriage I would sometimes buy magazines like Penthouse Letters that contained letters from readers describing their sexual fantasies and experiences. The letters would cover a very broad range or kinks, fetishes and fantasies. My wife and I would read them together and talk about which ones we thought were hot. The ones that always turned me on the most were the ones about wife sharing, cuckolding and cheating wives. Reading and talking about the letters really helped me to understand my desires and convey them to my wife. I think it also made us both realize that my cuckold desires were a common male fantasy. I doubt that I could have ever convinced my wife to cuckold if it hadn't been for those magazines. So thank you Penthouse!
You knew that your sister-in-law had been regularly cuckolding her own husband for years, and she made no attempt to hide the fact that she has wanted your wife to start cuckolding you too. You wife has resisted her sister's urgings for quite some time, but she has finally been worn down and she's agreed with her sister to go out on a date tonight -- with every expectation that by tomorrow morning she will have cuckolded you.
