She’s actually into it, her bimbo brain easily accepting his advances.

He couldn’t watch, and retreated a little, so he could only listen. After a pause that made Tom feel like his heart had stopped, he heard Sarah let out an airheaded giggle. “Well, like, if you think he won’t know.” Then, the unmistakable sound of kissing. Tom just stood there, unable to move, as he listened to his transformed wife making out with someone who was barely an adult.

Of course, some treacherous part of his mind whispered, this is all your fault. You made her that young. She’s closer to his age than yours, now. Tom didn’t want to listen to that line of thinking, but the thoughts kept coming. You could have put a stop to this anytime you wanted. You could have wished for her to be faithful to you, even as a bimbo. But you didn’t. You wanted this.

“Mmm,” Sarah moaned, “You’re, like, such a freaking cutie patootie. Why don’t we head to your room?” They walked away, and Tom couldn’t deny it anymore: he was hard. This was turning him on. A lot. Unable to stop himself, he waited a few seconds before following the footsteps, through the house to Jake’s room.

They’d closed and locked the door, but the walls were thin. “Oh! My! Gosh! Your dick is soooooo big!” Sarah squealed, clearly loving what she was seeing.

That made Jake laugh, and he asked her, “Really? Bigger than your husband?”

“Oh, totally,” Sarah said without delay. Hearing that didn’t make Tom sad, it just made him hornier. From there, he listened to the telltale sound of Jake’s cock being sucked by the bimbo who had been his wife.

It was getting Tom more and more aroused listening to it, until Jake spoke up again. “Hold on, I’m getting close, I want to finish on your face.” Sarah moaned at the suggestion with the cock still in her mouth, and just imagining how she must have looked at that moment, the stupid blonde bimbo with some kid’s cock in her mouth, made Tom cum in his pants.

It was hard, but Tom fought through the post-orgasm haze to scatter from the hallway, waiting until he heard his wife and Jake leave the room. “We have to do that again sometime,” Jake said, before Tom heard them kiss one more time.

Now that his arousal was gone, Tom didn’t know how to feel. That...had been really hot. He didn’t even feel sad, not really. After all, it wasn’t like it was even really his wife. He’d turned her brain off, and this was the consequence. The hot as fuck consequence.

“Hey, Tom, whatcha up to?” Her voice came from right behind Tom, and he turned around to see her looking at him, completely unaware that he’d just cum to the sound of her giving another man a blowjob. Hell, she looked so dumb in that moment, he wasn’t sure she’d be able to recognize the smell of his cum if she sniffed his shorts.
