By the time Kim came home that day, John had been both working out and driving himself up the wall with how cute he thought Amy was. He'd never been like this in such a long time, and he was far from used to it. When Kim saw her pumped up and energetic husband, she was almost overwhelmed by his sheer eagerness. She swore it almost did seem like she was having a relationship with a much younger man---wasn't that the case? John was...thirty one, wasn't he? She shook her head. She could not shake the sensation something had changed. But right now? She was not seeing too many downsides to it.
Even as they ate at the table John had his eyes on his wife. He bit his lip lightly and thought about what they could be doing tonight. Just the idea almost got him going again. John had never felt so vital and strong in the years...years? He'd been married to Kim. And he figured he could wait and handle this later. He needed to feed his strong, young muscles.
Kim was rather surprised likewise by how eagerly John shoveled food into his mouth, and how mature Simon was being the whole of his time at the table. That or Simon was watching all that was going on. She swore that Simon was getting bigger and stronger too, something seemed different about him and the way he carried himself. Eventually Simon spoke up and asked John, "Hey...uh, bro, guess your workouts really work up an appetite. How'd your day go?"
"Oh, amazing man! I got in my daily workout, and looked forward every moment to my lovely wife coming home." John answered with a cheeky smile.
Kim flushed red, she was already feeling like taking this young stud up to the bedroom and introducing him to some more interesting things he could be doing up there. Though she swore she usually had to remind John to shave, but right now he was looking like he had no need for shaving. Oh...right. John was aspiring to be a bodybuilder. Hadn't gotten far, but the build he'd worked up so far was fantastic. So of course he'd want to keep himself smooth as can be.
It did not take long for the two lovebirds to make their way upstairs after dinner, and Simon quickly put in some headphones and music to drown out what he knew would be a loud and stirring final coupling between John and Kim.
-------
Upstairs, Kim, much to John's embarrassment, had to help him unbuckle her bra. He swore he knew how to do that, but John just figured he was getting overexcited. That much could be gathered from his quickened heartbeat...and the rock hard erection in his shorts. Kim smiled at his basketball shorts and slapped his ass, drawing a gasp out of John. She playfully chastised him, "Basketball shorts, Johnny? Are you showing off your cute, tight glutes and legs? You little slut..."
He smirked and responded, "Ohh yeah, definitely. I love showing em off!" Again, he thought to himself, if I've got it I should flaunt it.
Kim guided John on to the bed and pushed down his basketball shorts, freeing up his sizable erection. John promptly let out a quick succession of moans as Kim put her mouth on his manhood, sucking away at him. Even though it was part of the norm, John had never felt so good getting this done to him. He figured it was just renewed sensitivity and let her have control of this part of their fuck fest. It was when she touched at his balls that he let out a louder, more eagerly sexual moan.
She stopped when she realized John was two steps away from cumming. At this point. When they'd barely started. Much as she enjoyed having a young man around the house, she hoped this was just an act. Even so she pulled off of him.
John gave her a pout and asked, "W-Why'd you stop?"
She giggled and teased him, "You were gonna cum too soon, dear."
John crossed his arms, "I was not!"
Oh yes, she thought to herself, he was far too cute for his own good. So eager to please and so ready to indulge. "How about I let you have my pussy?" She saw his eyes light up at that and a grin cross his face. Oh yeah, that got his attention.
Before long John was thrusting away into her, and Kim was almost impressed by how loud he was getting. She was usually the moaner and screamer in the sack, but today it seemed John was extra sensitive. She dragged her fingers over his taut, greatly toned muscles and let him position himself over her. In the process feeling for his back and loving the feel of his lats and wide form. He kept thrusting, deep and hard, letting his inclinations run wild.
And so John finally felt it hit him, and he said in a breathy tone, "I-I-I'm...I'm..."
"Yes, baby?" Kim whispered in his ear.
"GONNA CUM!!!" The orgasm was thundering and loud and both John and Kim saw stars, enough that after the full pulsations and emissions were done in the ultimately shared orgasm, both John and Kim wound up falling asleep in the aftermath of the session. Both wound up rolling over in the course of the night, and by the time it was safe for Simon to take out the headphones and head to bed, he wondered what changes would occur in the morning.

In the morning, Simon woke up wondering about what change would come upon him today, and he heard John starting to get up as well, the sound of the bedroom door swinging open. Simon decided to wait and see what had become of John since last night...
