Well...

Penny held Matt's hand and smiled as the RN readied the syringe. He smiled nervously and she gave him a reassuring squeeze.

"Last chance," the nurse said gently. "After this there's no going back."

Penny squeezed Matt's hand supportively. "Make me a moron."

Matt swallowed as he watched the dose slide through the syringe and into his wife's arm. As the nurse applied a small gauze pad to the injection site, he spoke.

"You'll notice it begin to kick in sometime in the next twelve hours. At some point, you'll realize that pain no longer holds the same meaning for you it once did. You won't change cognitively at that point, but you'll start to notice some differences in your perception. You might bite your tongue, or trip and fall, or hit your head on something, and you'll continue about your business without a second thought. That's when it starts."

Penny nodded. "And how long after that do the cognitive effects kick in?"

"It varies, but usually you change over the course of twenty four hours. They say it's a very strange but pleasant process. Your experience of the world begins to **** slightly as you lose your perception of the negative. You'll find yourself lost in thought, easily distracted, or just plain stupefied. Of course you can't get bored now, but in a few days you won't even remember what boredom felt like. You'll forget that you shouldn't zone out for minutes or hours. Matt, I assume you've read the paperwork on Boosted care?"

Matt nodded. "Yeah. I need to make sure to feed her and get her to the bathroom, right?"

"That's right," the nurse confirmed. "Until we now how strong the effect is on Penny, you'll want to treat her as though it's the worst possible case. That means reminding her of everything she needs to do and everything she doesn't. Ok, Penny. How do you feel?"

"Not any different, to be honest," Penny said. "But I guess I won't for a little while?"

"That's right," the nurse said. "Now, do you have any last questions before you go?"

Matt slapped Penny's ass and she jumped, surprised by the sudden gesture. "Nope! Just can't wait till I can do that without her even reacting!"

The ride home passed mostly in silence. Penny had promised Matt she'd tell him as soon as she started feeling anything. In the meantime, she gave him a generous helping of road head.

As they walked into the house, Penny went to the fridge to get a bottle of seltzer. She laughed as she opened it. "Man, it's weird to think that soon I won't even bother rinsing your cum out of my mouth."

"Why do you do it now?" Matt asked.

She thought for a moment. "I guess I figure you might kiss me at some point and you probably don't wanna taste your own spooge on my breath. That and **** of habit."

Now Matt laughed. "Good point. I'll definitely need to tell you to use mouthwash after you blow me."

Having downed the can, Penny sauntered up to Matt and put her arms around his waist. "I'm gonna be a such a dipshit! I hope you're as excited as I am, babe."

He reached around and gripped her ass, pushing himself against her. She could feel his rock-hard boner through his jeans. "I really am. I'm gonna break you down for parts, Penny. I'm gonna enjoy watching you wither away."

"And I'm gonna enjoy withering away," she echoed. She pulled him into a tight embrace and reached down to stroke his cock. "I'm gonna feel my mind slowing down while you rail me. I'm not gonna be able to think straight or walk straight."

"Well, while you can still walk straight, why don't you get me a beer?" he replied. She giggled and turned to go to the kitchen. He smiled and fell back onto the couch. Life was good.

After a few seconds, Matt frowned. He heard Penny open and close the fridge door, but he didn't see her. He turned to see her staring down at her foot, unresponsive.

"Pen?"

She looked up at him with wonder.

I... think I stubbed my toe?" she said, more to herself than him. "I stubbed my toe?"

"It's happening already, isn't it?"

Tears welled in her eyes. "Yeah. It's happening."
