Cute story and I understand the moral of the story. However, being a married woman of 20 years unless this was a very new marriage this one would have known this wasn't her husband from the first. How? 1. The guy would smell wrong - every man has his own distinct smell and if you have had sex with them for a little while you can recognize that smell in your sleep. 2. each man has different sexual technique and does things differently. You will immediately know that's a different man from how he has sex. 3. Each man's "member" is a different size and you will DEFINITELY know that. 4. Each man tastes different, you would know that was not your husband just from one kiss.
So, a true telling of this story would have ended the first night . . . unless the guy was better at giving orgasms than the husband, then it probably would have carried on but the wife would have kept her mouth shut. Hahahaha
