The mother, Maria, came back in and saw all the kids fighting over the remote and she yelled "Time Out!" at which point all the kids froze. Maria may have been older, but she had respect and fear from her kids and their friend. She approached them and grabbed the Sex Machine out of their tussle and said "If you can't play with some new toy kindly then I'm going to take this... odd area 51 remote? And you all can have it back tomorrow." Then Maria pocketed the Sex Machine and went back to the kitchen to finally put the food in the oven. Kris felt blue balled, and while John and Kimberly were disappointed they felt relieved to not essentially be raped in a way... Although both had to admit they wouldn't actually mind going through that again.
The day passed, John and Kris did some homework and then Kris went back home, they had a family dinner and John and Kimberly were both closer and more quiet towards each other, and Maria and her husband Eric noticed. Eric himself was a few years older than Maria and was seriously considering retirement sooner or later. His hair was more grey than black, and while he was sturdily built the years had been wearing him down.
Back in their room, after dinner and getting into their pajamas, Eric asked "Maria, so do you think something happened to our kids?"
Maria responded "I think, earlier today they made a bit of a ruckus in the family room... and then they were fighting over a remote... Oh yeah let me grab it." and then she opened up the hamper, got out her pants, and fished out the Sex Machine. She handed it to Eric and asked "Do the symbols mean anything to you?"
Eric chuckled and said "It's some gibberish, kinda reminds me of old sci-fi gibberish. The type that would go-" He presses the button once towards Maria "-Dance!" to which Maria chuckled and pretended to dance for a second and then Eric pointed to his limp penis and pressed the button and said "Jump!" For sure their sex life had gone down in age. They for sure had a lot when they were younger, but they kind of lost a lot of their sex drive. Which made them more surprised when the Sex Machine started working and Eric got a healthy boner which seemed to be growing as fresh testosterone flooded through his body. His hair darkened back up, wrinkles smoothed out, muscles unatrophied, and his height claimed by the years came back living him a spry youthful stud. Eric was so enamored with his body he stripped and checked himself out in a full length mirror, and flexed his muscles. They seemed bigger than he remembered, but then again it was awhile ago... same thing with his penis.. Enthralled he laughed and said "Do you see this Maria! Somehow I'm back in action!" and then turned around to see his wife... Oh his wife... Maria's luscious long wavy hair had it's dark brown color back and it looked so soft and full, her skin seemed so smooth, all the stretch marks and sagging that came with having two kids were gone, her hips and ass were wide and plump, her waist was just a little wider than the short side of a piece of paper, and those breasts of hers seemed to have been smoothed out and overstuffed. her sweatshirt and pants having turned into a sexy pair of black frilly lingerie.
Maria responded in her old young sexy voice "Heh, it's been awhile you old stallion." a moment passed between the two as they steadily got hornier and hornier until they couldn't wait and Maria leaped into Joseph trusting his old strength would let him carry her. Which he could easily and Eric enjoyed every millisecond that his wife felt like a feather in his arms, but with some extra dexterity he was always flipping her a bit and removing her lingerie allowing easy access to her hole, and allowing her large mammaries to bounce free. They arrived at the bed and he jumped on it back first and allowing Maria to land on him a little and she turned around and immediately knowing what they both wanted started to sit on Eric. In the right position where his dick would penetrate her pussy and she enjoyed the feeling and squatted down slowly so they both could enjoy the ride, and after feeling sufficiently full she went up and down. They both were enjoying this as Maria felt dominant in the relationship after a long time, and Eric was enjoying both the feeling and the boob show from Maria bobbing up and down so much. Maria orgasmed multiple times in that endeavor, but Eric held his load for a decent amount of time... but after a few minutes he had enough and needed to blow his load. The two then collapsed in bed snuggling Maria said "I love you..."
Eric could only say "Yeah, I do to. It's been too long since we did this..." and then Eric stared into Maria's eyes only somewhat aware that the years were coming back to them, and Maria did the same. Thankfully for their modesty most of the sweat, body fluids, and discarded clothing went away as they were fully reverted back before the Sex Machine had changed anything.
Maria then giggled and said "You know I think that John and Kimberly accidentally did what we just did."
Eric grinned "Oh did they? Well we have something to hold over their heads for awhile. John, how dare you fuck your sister!?! But with how magical that thing was... and how powerful that lust was... I can hardly blame them." And then as they lay in bed the aging couple started stripping.
"Once more?" Maria asked
"Just Once? I don't even feel a little fatigued, let's do this at least a dozen times!" Eric exclaimed trusting that their distance from their kids rooms would keep this a semi-secret, and once stripped Eric grabbed the Sex Machine and pressed the button twice again before putting it back on their nightstand as they both started feeling younger... but started feeling different. Eric quickly noticed that his boner had completely given up and tucked itself in for a good night sleep as he now had a slit where his penis should be, and his atrophied muscles smoothed and softened into supple curvy skin that continued to get curvier and curvier by the moment. Although she felt big Eric was more slim and her boobs were only C-cups, and Eric wasn't exactly sure how she felt by the fact that she was now a she. She had tits right on her chest, but she wasn't attracted to them... Then looking to her now husband Maria. She was BIG, buffer than Eric ever was, really hairy all over, a beard, and a... rather size-able... member... "Oh God! Why am I thinking like this?" Eric asked blushing?
Maria chuckled and said "I think it's the remote, if we're going to have sex may as well make us attracted to the other. Must say it's interesting I never got entirely why men liked tits so much, but now I kinda do." And then a wave of horniness washed over them. Causing Maria's boner to stiffen further, and force Eric to feel the need and desire for that cock... Maria took dominance again as he put his cock in his once husband.
Eric thought to herself "Ugh, this feels... oddly satisfying... having him in me like this. Ah he's thrusting! This motion... it's Ah Hot!" Maria had cum a little early
Maria "Ah... sorry Eric, I'm not used to a dick and it was so intense... how about I help you out a bit more." and then began playing with Eric's nipples, tweaking, licking, and sucking on them. All while giving her a good fingering. After Eric came the testosterone and age started coming back to his body as he was breathing heavily. As his dick came back out he noticed it wasn't covered in cum or anything. Maria back in her soft old woman form asked "So what did you think?"
Eric could only respond "Well... different, It was kind of like being someone else but... yourself?"
Maria giggled and said "I know right? But how was that body treating you?"
Eric chuckled and said "It was all good till you blew your load too quick."
Maria pretended to scoff and said "Well you weren't much better when we first started."
Eric grabbed the Sex Machine, grinned and said "Well then let's get more practice, The night is young after all."
