He continues his fun

"Nah, she's still up," Curtis answered. "But about her, I have some bad news..." he paused, letting his words hit home.

"What? Is she okay?" Jimmy asked.

"Yeah, yeah, uh, don't worry about that. It's just that I think she might be cheating on you." Curtis felt the woman's stifled laugh, and he pressed his foot into her pussy harder in warning.

"No. What are you talking about? There's no way," Jimmy said. His voice was careful, like he was holding back his reaction.

"Look, Bro, I don't want to be the bearer of bad news, here, but you need to know. I've seen her quite a few times recently before you got home, and she looked freshly fucked. Like, hair a mess, clothes askew. I swear more than once I caught her sneaking out at night, too."

"That doesn't mean anything! You know she works long hours and goes on late night walks," he said. Now he was starting to sound angry.

Curtis shrugged, "I don't know what to tell you. Look at the facts, man, she's young, she's the sexiest woman, maybe ever, and she works around a lot of rich, powerful, good looking men. Have you missed that she's attracted to powerful men?"

"Well no, but..."

"And do you consider yourself to be a powerful man?"

"She married me anyway!" he said automatically, his default response.

"Sure, and I know she's a good woman. But you've got to face it, she's fucking insatiable. She can fuck for hours and still want more."

"That doesn't mean... wait. How do you know..." Jimmy's eyes searched Curtis' face.

Curtis sighed dramatically, "look, I didn't want to have to prove it to you, but..." he threw the blanket off the kneeling sex bomb, currently trying to work his cock deep into her throat. Hair messy, over her eyes, she made eye contact with her husband and waggled her fingers in a wave.

Jimmy shot to his feet, taking in the situation. Curtis waited while Chelsea began allowing herself to make more noise. Jimmy seemed to make up his mind about what to do, pulling his fist back to punch.

"Wait, wait, are you gonna hit me?" Curtis said, as fast as he could.

Jimmy snarled at him, "no, but this is really fucked up."

Curtis knew he should feel bad, and was glad he'd done away with stupid shit like guilt. "It's not so bad. Chelse thinks it's hot as fuck."

Jimmy looked pleadingly at his wife. "No, that's not true. He's bribing you."

Chelsea giggled and shook her head 'no,' cock still in her mouth.

"Face it, Jim, your wife is a cold slut. This whore has been on more cocks than times she's been on yours. C'mon, there's no way you actually believe you could satisfy her."

"But, you said..." He sunk onto the couch, his world going up in flames.

Curtis began rocking his hips forward, driving himself deeper into the woman's throat. "I think you like this. I think this is what really gets you off."

"Hmm?" Jimmy said, defeated, as if nothing could surprise him again.

"You like your wife jumping from dick to dick, used like a free whore. You like seeing her on my dick, and knowing that you're the weaker man."

"I don't," Jimmy said. He no longer would look at the pair.

"If I'm wrong, then this won't be a problem. See, I have a sticker here," he removed a sticker from his pocket, displaying the museum logo. "You won't be able to take it off." Curtis stuck the sticker to Jimmy's lower back. "It'll never come off. It's a magic sticker. For one thing, with it on, you'll never decide to leave Chelsea, or move out, or in any way stop performing as her spouse. Additionally, every time you get even a little tiny bit horny thinking about her having sex with someone that isn't you, your body will get a little more feminine, until you're completely a sexy woman with a bimbo's body. Is anything I'm saying false?"

Even before Jimmy could respond, his body did. His hair grew a noticeable half inch, his jawline weakened, and he shrunk a quarter inch. Less perceptibly he gained just the tiniest hint of breasts.
