Um, WOW! Nice twist, I really like the mature content.

Only one slight bit of foreseen confusion. In my story, it’s fact that his wife is sleeping. So, if anyone sequels this, then it must be mentioned that she knew there would be a day that this would happen, as part of the fantasy, of actually waking up to this encounter.

My cousin is pretty wild, and sexually adventurous. She and her husband plan these scenarios, in hotel lobbies, parking garages, alleys, making your twist all that more believable.

So he does it right there with the other woman out on the fire escape? Pretty hot!

lol, I wasn’t going to go there, but you did a great job with it!
