This guy managed to break the tags. If you read the NTR tag definition, this barely qualifies since half of the doujin is both of them enjoying themselves. But there's double cheating tho. The husband changes into his wife so it's gender change, but does it also qualify as clone? Since the wife isn't the one cloning herslef and the clone doesn't have the same personality, it's kinda ambiguous. And that also begs the question whether this counts as selfcest or not when the wife fucks her husband in this form.
My pp isn't confused cuz I don't like NTR stories, but my brain definitely is. Props for giving me a good laugh. The clone yuri action was good tho. Too bad.
