Plant some seeds and wait for them to grow

An idea formed quickly in your head, and before Jennifer could leave the room you told her one last thing. "Since you hate this kink so much, you must not like it when Marcus tries to push it on you, right?" You asked it as if it was an ordinary question, knowing the hypnosis would make it anything but that.

She paused, then looked back at you. Only a brief moment of conflicted hesitation passed before she admitted, "Yes. I don't like the idea of him pushing it on me."

"If that's the case, you're going to be more unsatisfied with your relationship, more upset at him, and more convinced he's a pervert every time he brings it up again, aren't you?" It made you want to laugh. Saying something like that in any normal circumstance would have made it transparently obvious what kind of paper-thin manipulation you were planning, but the app covered for that, laced your words to make them so much easier for Jennifer to swallow.

Though at first, you weren't sure if she really was going to swallow this one. She looked thought about it longer than expected, before nodding, sadness in her eyes. "You're right. If he is stupid enough to harp on about it, all of that is true." Then she left the room, and you heard the front door close not long after. She'd left the house.

Perfect. For the next phase of your operation, you left your room, heading out to see Marcus looking sullen, sitting on the couch with his head in his hands. You sat next to him, and put a hand on his shoulder, as though you were really trying to comfort a hurt friend. "Hey, it's going to be okay."

"No it's not!" His sorrow turned to anger in a sudden swerve, and he pulled away from your hand. "You telling her about my fetish ruined everything! She said she was just going to clear her head with a walk, but...fuck. I shouldn't have admitted to it, she's never going to look at me the same way again!"

It was hard not to give the game away with a laugh. Your poor idiot of a friend didn't know how true that was. And neither did he know how much worse you were about to make it. "You're completely wrong, Marcus. It's a minor setback, but I think she's secretly interested in exploring this. All of her shock and anger is just a cover for her embarrassment over thinking it sounds hot. I mean, don't you get a bit embarrassed over it too?" Even as you said the words, you could see them worming into his head, shaping how he would see the situation.

"I guess...yeah, that could be true..." he admitted.

"It is true, man. Don't give up! Just keep reaching out about it, at least two or three times a day. Persistence will wear her down, I'm sure of it. And the more she tells you to stop, the more you can know it's working, you're getting closer to the answer you want!" Or rather, the answer you want. Namely, getting to fuck Marcus's hot wife.

Nodding his head, seeming less shaken and more confident by the second, Marcus actually smiled. The rube. "Yeah...yeah, that's right! I'll just keep at it."

With those seeds planted, you watched a football game with your friend, knowing all you had to do now was sit back and enjoy the fireworks.
