Julie Crenshaw sat at the kitchen table. Dim lights. Blurry faces. Blurry voices droning out the song.

All that was in focus was a big birthday cake, candles burning merrily on the top, sliding in place in front of her.

In slow motion a deep voice called out, as if from far away, “Mmmmmaaaakeee aaaaa wwwwwiiiiiissssshhhhhhh...”

The candles grew brighter. And brighter.

And even brighter...

Julie startled, fully awake. There was no cake. No candles. The bright light was the sun.

And the sun felt good.

No, it felt really good.

*REALLY GOOD*

Her breath caught as the view turned. The sun was now way off to her left, where she could no longer feel its rays. Except ... she still felt really good.

She struggled to focus. But she’d never felt anything like this before. And the ‘good’ feeling was ... WOW!

It was ... it was ... it was between her legs?

She forced her eyes to actually see what was in front of her. She could see a little of her nose and cheeks and chin ... wearing rather more makeup than she normally used. Huh...

Ignore the WOW and keep looking, she chided herself. A little farther, and she could see the white button-up blouse she was wearing. Fancy. But ... wait ... she must have been wearing a padded bra, because it looked like she was at least two cup sizes bigger than she actually was.

No, focus. Fo! Cus!

She looked past the strangely larger chest, and saw a knee-length skirt. Dark blue. Quite modest. The sort of thing she’d seen teachers wear before.

The strange part was that the top of it was down a couple inches below her actual knees, leaving her thighs completely bare.

Smooth pale skin, except for a swatch of darker and hairy-er skin that crossed it.

Skin that was moving...?

Wait! That was an arm!

An arm reaching over from her left, and crossing her naked thighs!

Why was...? Oh.

Oh no.

She followed the path, and saw the hand buried in the middle of where the WOW was coming from. As her church youth group put it, touching her ‘sacred garden’.

Julie tried to tell whoever was doing this, “No. I am saving myself for that special someone, on my wedding night.” Just like the youth pastor had taught.

But all that emerged from her mouth was, “Nnnnn ... Ohhhhhhh...” And even to her innocent brain, that sounded more like ‘keep going’ than ‘stop please’.

“Ooh, sounds like you’re ready for another one!” came an unfamiliar voice to her left. Julie tried to figure out if she had the energy or ability to look that way. But a more pressing matter caught her limited attention.

Namely the matter of this stranger pressing his fingers inside of her crease. In between... plowing her sacred garden. It felt ... Beyond WOW!

Maybe it was just the fact that someone other than her was touching it, but everything felt thicker. And more full. Or ... ripe ... or...

She gasped! His fingers had rubbed over her most sensitive spot. The ‘heart’ of the sacred garden. One of the two places she’d been told to protect the hardest.

And then he did it again. And again. And— and— oooOOOoOOOoo...

What little grasp of intelligent thought flickered, as he caught into a rhythm that was just ... PERFECT!

And then his thumb was flicking the spot, as his other fingers slid lower. To ... OOOOHHHHHH ... the other spot to protect. Her ‘godly cave’ that...

Oh wow! OH WOW!! *OOHHH WWWOOOWWW!!!!*

He’d ... slid his fingers inside her: One. Two. Three! Easy peasy. Like her body had done this before.

Like it knew all the steps to the song, and was just humming along until it could remember the words. Or something ... it felt too good to really think right now.

And the WOW kept building and building and building ... She could feel an edge in front of it, one that she was rapidly approaching, but one she had no idea what was beyond.

She could hear herself now. Little gasps and tiny moans, slipping from her lips without any effort at all. Her hips were twitching, flexing faster and faster, keeping time with the stranger’s movements. As if trying to make him move even faster, even harder, even deeper inside of her.

And then that cliff was there. No warning, no notice. Just one second there was buildup, and the next?”

“Yuh ... yuh ... yuh ... y-y-y-*YYYEESSSSSS!!!!!!*” she was screaming, and wave after wave of pure ecstasy flooded her body.

For a second she thought she saw the bright light of candles again, but it turned out to just be the sun again. They’d turned, and were now sitting still while she caught her breath.

In a ... car. Yes, a car. The words came back to her ... although the reason why she’d gone from her birthday party to sitting in a car with a stranger who had been touching her? That was still eluding her.

“Right on time, Jules,” said the stranger’s voice. And this time Julie felt like she had enough energy to turn and look at him.

She felt herself pale. He was ... old. Like, maybe ... almost ... forty!!!!

She felt herself get a little sick at the thought of some old creep touching herself that way ... but another part of her was cataloguing how attractive the old man was.

Tall, broad shoulders, a distinguished speckle of grey across his temples...

Wait. ‘Distinguished’? Where did that word come from?

He reached over and rested his hand on her leg; something both comforting and mortifying (as she was still completely exposed from knees to navel). “Jules? You there? Or did that last orgasm erase your memories again?”

“W-w-what?” Julie finally gasped out.

The man squinted a bit, as if searching for something in her expression. Something he didn’t find. “Well, shit,” he cursed. “A fucking third time?”

“L-language,” Julie stammered out.

He rolled his eyes at her chiding. “Listen, whatever you think is going on? Look in the mirror and guess again.” He waved at the car’s sun visor, and then sat back and ignored her.

With a trembling hand, she reached up and flipped down the little makeup mirror. Then boldly stared at the person in it.

Staring back at her was ... her. Distinctly Julie in every way. A bit more made up than the ‘natural’ look her mother allowed her to have. With a professional looking shorter hairstyle that wasn’t something she’d ever thought of doing, but didn’t look half bad on her.

And, the biggest thing.

The Julie in the mirror was at least twice her age. Maybe more.

Which was ... impossible.

She started to pat her cheeks. Maybe the heavy make up was actually some movie stuff that made her look older...

“You’re thirty-four,” the stranger chimed in.

“What?” Julie asked, unable to turn away from the mirror to look at him.

He drawled out, almost sounding bored, “Thirty-four. On your last birthday, a few months ago, that’s how old you turned. So you’re aware.”

She finally stopped examining herself and turned to look at him. “No,” she scoffed, shaking her head. “That’s impossible.”

“Well ... it’s unexpected, I’ll give it that.” He unbuckled himself, and leaned over so he was looking Julie right in the eyes. “Long story short? You accidentally took the wrong medicine. It had an interaction with the right medicine. And one of the side effects? For the next few hours, your mind could’t ... find ... the connections to recent memories. Like, the past umpty-odd years recent.”

He tapped Julie in the middle of her forehead. “They’re still there, just ... inaccessible. Like they’re in a 7-11 vault with a time lock. When the medicine runs its course, or something manages to jog some loose, they’ll come back.”

Though it felt impossible, Julie’s eyes flicked over to glance back at her reflection in the mirror, and swallowed down her instinct to actually say that out loud.

“Anyways,” he said, after he saw Julie wasn’t going to respond, “we may want to head on inside. Driving down the freeway is one thing, since there’s not many options out there. But I don’t think you want to take care of the other side effects out here.”

She slowly started to unbuckle her seat belt, as she asked, “ ... other ... side effects?”

“Well, Jules...” he gestured, a lot more awkwardly, towards her bare skin. “It sort of also makes you unstoppably horny.”

Julie, remembering her state of half-undress, quickly pulled her skirt back up and securely zipped and fastened it shut.

“That’s ... that’s not a thing!” she protested as she stepped out of the car, although her wobbly legs put a bit of a lie to her words.

The man threw up his hands in a jokingly protective stance. “Hey, you’re the one that told me the possible side effects, so don’t blame me. I’m just the one you asked to help you ... deal ... with them.”

She paused, then glared at the stranger once again. “Who ARE you?”

He thought for a moment. “Huh. Guess I didn’t introduce myself this last time. Bernard. I’m Bernard. At your service.” He gave a small bow, which should have looked goofy, but instead Julie found something in the back of her head starting to salivate.

“Okay. Well ... Hello Bernard. Pleasure to meet you.” She covered up any thoughts on Bernard’s attractiveness by defaulting to politeness.

He waved her through the front door of the house, then shut the door behind them. “Well, Jules, I’d say the pleasure was all mine. But those little whimpers you were making five minutes ago would make me a liar.”

Julie missed a step at that, and almost fell. Only being caught by Bernard and held in his strong arms kept her from kissing the marble floor.

Instead he held her still for a moment, before she was pushing her head up and he was tilting his down, and instead she was kissing Bernard.

It was her first kiss ... and yet it wasn’t.

Julie couldn’t remember ever kissing anyone before (and, no, giving Aunt Tanner or Granny a peck on the cheek did NOT count). But apparently her body knew what to do.

It started simple, the comforting press of lips to lips. Hers with a bit more lipstick than she remembered using. His, slightly in need of chapstick.

And then his lips parted slightly and his tongue gently caressed her lips, and she was reacting on automatic.

Her own lips parted, and then his tongue was inside her mouth. Or maybe her tongue was in his. Possibly both at once, she couldn’t keep track. It was just ... overwhelming.

Perhaps, she thought, there was some truth to the ‘overwhelming horniness’ he’d mentioned, as she felt no desire to push him away.

She thought she felt one hand of his roughly grabbing her ass through her skirt. Which was fine as she’d done the same to him.

There was some stumbling and bumping against furniture and walls, which paled in significance to Bernard leaving a trail of kisses down her neck until he found a sensitive spot and started to suckle it. Hard. While she breathlessly whimpered out his name.

His hand left her behind, and a rattling noise led to the wall behind her turning into a doorway. They stumbled into a dark room that lit up brightly after she slapped her hand against the wall in a blind search for the light switch.

And then she was sitting up on a bed, and Bernard was stepping away from her as he slid his tie off and tossed it to the ground.

As he started to unbutton his shirt, Julie looked around. The bedroom was ... not ... a bedroom...

“Where are we?” Julie asked.

Bernard paused in undoing his buttons, and glanced around. “Huh. I thought we were in the master bedroom. We got turned around early, as we’re in my photography studio on the complete opposite side of the house.”

Julie studied the strange and futuristic-looking equipment that filled half the room. The other half being where the two of them were at, with half-created partial rooms smooshed together. A bathtub three inches away from a fireplace and bearskin rug, and both adjacent to the silk-sheeted bed she was currently sitting on.

Bernard, the last button of his shirt coming undone, said, “if you want, we can walk to the actual bedroom?”

For a moment, as his shirt fell to join his tie, she just stared intently at his body. Muscular, but not in some gross weightlifter way. With a bit of softness over it, in what a little voice in the back of her head called a ‘perfect dad bid’.

Forcing her gaze away she fiddled with a pink leather strap over her shoulder, realizing that it was a purse she must have instinctively grabbed when she’d gotten out of his car.

“That’s a possibility,” she agreed, peeking inside the purse. Sitting on top were her panties, which she realized she hadn’t seen when pulling the skirt up. And, half-wrapped in them, was a note. With her own signature visible on the bottom.

She carefully pulled it out m, hoping it had a bit more details.

Instead, it was very simple.

“Hope you enjoy this tasty treat. —Julie”

She looked back up as Bernard pulled his slacks down, leaving him only in a pair of slim purple boxers, and licked her lips. “Oh, I think I will...” she murmured.

“What’s that?” Bernard asked.

“Nothing,” Julie said, louder. “Just that we don’t need to go anywhere else.”

He gave her a look full of hunger. “Is that so?” His eyes trailed up and down her body. “In that case, I think one of us is a trifle overdressed...”

Julie blushed, then started to shakily unbutton her blouse. “Th-that’s easily fixed,” she called out, the bravery she was trying to display completely fake.

She had no idea what she was doing. Sure, she might have lived a lot longer than her memories told her, but that didn’t help in this situation.

Except, maybe it did. When she stopped thinking about what she was doing her hands had glided quickly and neatly down her blouse and the buttons just seemed to melt open.

And so she let her body use whatever instinct was still there to shrug out of her blouse and tug Bernard towards her.

Her breasts were pushing towards him, her back arching to present them, as she fumbled behind her with her bra hooks.

“Are you r-ready?” she asked, as this was a bit trickier than the one she remembered wearing half-an-hour ago. He nodded, a goofy grin on his face.

She finally got the last hook undone. “Be ready. I’ve never let anyone else see them before.”

Instincts had her start to slide the straps off her shoulders, but Bernard caught her hands and held them almost still. “Hey, this isn’t just because I gave you the first real orgasm of your life a few minutes ago?” he asked.

Julie licked her lips. “N-no...” she stammered. But as his eyes started to flick away from hers and down to the soft curves that were slowly being exposed, she relaxed. “No,” she repeated. “It’s because I plan to have you give me the first *few* real orgasms of my life.”

With that she gave a tug and her breasts were fully freed. The fight he was having to keep looking her in the eyes was lost, and he just stared in amazement. “Wowwww...” Bernard breathed out.

Julie agreed. They were much larger than she remembered. A quick glance at the bra still in her hand showed a ‘DD’ on the tag, which was ... damn, older self! She’d just been working on finding a new ‘C’ because her ‘B’ pair was starting to pinch! This was quite an upgrade.

And they turned out to also be a LOT more sensitive, as he gingerly cupped them, swiping his thumbs across her large nipples, and she found the bra slipping from her fingers at the stars this shot behind her eyes.

He started to caress and play with them, and all Julie could think was that it was a good thing she hadn’t known it felt this good, or she might have let any random guy who wanted to touch them.
