I didn't have to tell my wife she walked in on me getting fucked. The talk didn't even stop. He just kept fucking away at my ass. My wife still loves watching me get fucked. She finds it hot and sexy that I take another man's cock and cum in my ass
So, don't tell your wife. Put on your nylons and enjoy feeling a hard bare penis entering your rectum and fucking you until he cums in you and pumps his seed deep into your willing submissive body where you want it and it will help to further feminize you. Telling your wife is the last thing that you want to do.
