The sun shone brightly in the park, giving the whole place a warm, inviting feel. Children’s voices echoed from the playground, competing with birdsong and a dog’s excited barking. Pyotr smiled, walking through the grass with his notebook toward his old thinking spot, a hill overlooking the rest of the park.
As much as he enjoyed his sisters’ company and the feeling of family they filled the house with, Pyotr had never found it easy to get any work done around them. Sera was always nearby, seeking a partner in crime, and when she wasn’t, Anna would be pestering him out of semi-malicious boredom. Or his mother would want him to do chores. Always something.
In places like this, green places where no one would come seeking him, Pyotr was able to relax and to think. It was here, on this very hill, that he had first been inspired to pursue Temporal Physics. Whenever he had an unsolvable problem, he would invariably gravitate toward this place, or one like it.
Today, feeling refreshed and relaxed, he sat in the grass and contemplated Ehrenfest’s theorem. It had long vexed him, as in order to change an object’s motion in time he would have to be able to track it on both the Newtonian and Quantum levels. Unless he didn’t mind its molecules rearranging at random; that would be fine for a glass of water, perhaps, but less so for a person.
Pyotr’s mind wandered down a strange path, wondering if a puddle with random molecules of formerly-glass silicates in it would be safe to drink, when a shrill cry burrowed itself into his skull. Jerked back to reality, he glanced down the hill toward the source of the sound.
A woman sat on a bench by the footpath, rocking a baby in her arms. She appeared to be trying to calm it down, but the child was inconsolable. The mother reached over into the stroller parked next to where she sat and pulled something out of it, then began unbuttoning her blouse.
From where Pyotr was sitting, he got a quick flash of the woman’s bra and the curve of her breast before she pulled a privacy sheet over the baby and her torso. She shifted, pulling one breast out of the bra and moving the baby to it, then leaned back on the bench to wait while the child nursed.
Pyotr stopped time without even thinking about it, pushing to his feet and walking down the hill. His footprints once again left imprints in the grass, and he wondered if the sound of them all rustling at once when time started again would be noticeable. Arriving at the bench, he walked around for a better look at the woman.
She was in her early thirties, with dark, wavy hair past her shoulders, soft features, and an aquiline nose. She looked to be in the magical range of neither fat nor thin, muscular nor lean. Pyotr lifted the sheet that covered her upper body and drew a surprised breath.
Her tits were a cup or two larger than expected for her body, but not so large as to be out of place on her. One of them hung from her open blouse, obscured by her child’s head, and from the shape it looked to be very real. The baby looked very pleased to be suckling on her dark pink nipple, and Pyotr didn’t blame it.
Still moving without really thinking, Pyotr pulled the other side of her blouse open. Her left breast was still restrained by a bra, but it was one designed to easily be pulled out of the way. He freed it from its confines and rubbed it in his hands, gently squeezing it and rubbing his fingers over the nipple.
The tip of the little fleshy nub felt hot and damp. Pyotr leaned in, lifting it to his lips and sucking, lightly squeezing and massaging the great fleshy pillow. A rich, sweet flavor filled his mouth, reminding him of years long-past when his mother would make him warm milk with honey and nutmeg to help with insomnia, before he learned to shut off his brain at night.
Suckling and swallowing, Pyotr let his mind drift on intermingled waves of nostalgia and arousal. He barely even noticed the throbbing in his pants, so lost was he in the sensation of the matronly woman before him. He softly moaned, then snapped his eyes open.
Of course! That was it! Pyotr let go of the woman’s breast, running up the hill for his notebook and flipping it open. He scribbled furiously, deriving formulae from memory and plugging in data constants. When he was finished, he fell back on the grass and laughed.
Who would have guessed that Ehrenfest’s solution would be so glaringly simple? Certainly not Pyotr. He’d been overthinking it the entire time. It wasn’t until the complete relaxation of playing with the anonymous mother on the bench that he’d stepped back far enough to see not just the whole picture, but the frame as well.
Pyotr resolved to never fear his power again. If it could lead to real discoveries, then a minor moral compromise was nothing to balk at. Besides, if it led to an important step in solving time travel, he felt certain any woman would donate a little of her time and body.
Returning to the woman, this time with his notebook close at hand, Pyotr sat on the bench and sighed. The sun was bright, and it shone in equal warmth on his face and his companion’s breast, which in turn reached out toward it, pulled into a perky and pointed shape by his earlier attentions. Sighing, he rested a hand on her thigh. He wondered who the baby’s father was, and whether he knew the peace his wife’s tits could bring.
“Oh well,” he said, sitting up again. “We may as well put this thing away.” He reached over and gave her breast one last affectionate squeeze, then loaded it back into its cup and returned the blouse and sheet to their former modest positions. He smiled and brushed a lock of hair back behind her ear, then returned to his hill behind her, a little closer than he had been before.
The woman moaned when time started, then quickly covered her mouth with one hand. She looked around to see if anyone had heard, but Pyotr was pretending to read his notes, and probably looked very inconspicuous.
She relaxed again and seemed to forget about the incident, and after a couple minutes the baby finished nursing. She burped it and put it into the stroller, then got up, stretching.
Another woman was approaching, pushing a similar stroller. On a whim, Pyotr stopped time and did a quick supply run; in less than a second, he had a microphone, connected wirelessly to an earpiece, planted next to the sleeping baby. It was a demo unit from a local electronics store; he made a note to return it later.
“Morning, Julia,” the second woman called. “How’s the little one?”
“He’s sleeping. And yours?”
“Same, finally.” Now that she was closer, Pyotr could see that she was not nearly as exciting as Julia had been. Not particularly tall, slightly overweight, and already developing worry-lines; she was pretty much the housewife stereotype all over.
Pyotr tuned out much of their conversation. It was pretty standard mother chit-chat. He found himself wondering, following far behind as they walked, whether Julia was tuning it out as well, simply talking on automatic without really paying attention.
A teenager on rollerskates came around a long corner toward them. He was going faster than he probably should have, which Pyotr found annoying. Waiting until the kid was about to pass the two women, Pyotr stopped time and kept walking. There was no need to hurry.
As he had expected, the kid’s eyes were locked on Julia’s chest. Even buttoned into a blouse, it was impressive. With gentle, careful movements, Pyotr opened the blouse and pulled the bra’s cups down under Julia’s breasts.
Pyotr wished he could get closer, but the kid’s reaction was enough when time started again. Seeing Julia’s tits apparently bursting out of their bra under her blouse, he stumbled, veering sharply onto the grass and wiping out in some bushes.
“Shit,” Julia said, stopping and undoing a couple buttons. “Sorry, Mary. This stupid maternity bra keeps sliding around.”
“Serves you right for being so thin with such amazing tits,” Mary replied.
Julia scoffed, reaching in her blouse and shoving her breasts one after the other into the bra. “You know I said I could help you with the weight.”
“No thanks, I like twinkies. Besides, Jack doesn’t want nearly as much sex anymore!”
Pyotr shook his head. It was always sad when a woman decided she did not like having sex with her husband, but he supposed he couldn’t judge, not being married or a woman.
He wondered about Julia. She wore a ring, so she was probably married. Did she love her husband? Was she faithful to him? Did she still have sex with him? How easily would she cum?
That last, he realized, was something he could test. Granted, until he figured out true reversal of time, testing human behaviors and responses was an academic hobby at best; if he could crack the time problem, he could revolutionize behavior studies, and gather data without subjects having ever been affected by the experiment or any other variables, simply by going back to before the test even happened and re-testing.
For now, however, he could still perform informal tests. He walked faster, stopping time and catching up to Julia and Mary.
Julia wore loose-fitting jeans and comfortable-looking shoes. Pyotr reached around her from behind to take the jeans down, letting his eyes drink in the smooth curve of her ass and the way her panties stretched tight across it. He pressed his hips up against her, breathing warm air on her neck and sliding a hand in her panties, down through a patch of soft hair and to the entrance hidden below.
He stroked her outer lips three times, then grudgingly pulled her pants back up and hid behind a nearby tree to start time.
Julia stopped mid-stride and gasped.
“You okay?” Mary asked.
Julia nodded. “Just a weird feeling. Hope I’m not coming down with something, that’s the second time today.”
Pyotr gave Julia a minute to cool down, tuning out the idle gossip she and Mary were engaged in. It was mostly meaningless, anyway. People could say so much without saying anything at all; it was amazing sometimes.
Eventually, he decided sufficient time had passed to reset his experimental variables. Or more accurately, he grew tired of watching Julia’s ass while she walked without touching it. Catching up again and kneeling before her, he wasted no time in opening her jeans and sliding them down off her hips.
Pyotr ran his hands up over Julia’s ass once, stroking it and admiring the curve, then brought his hands around in front. Gently, he spread her lower lips and slid two fingers inside her. He didn’t pump or stroke them; he simply inserted and then removed.
The fingers came out sticky. Pyotr slid them up, pushing back the little hood of skin that hid Julia’s clit, and smeared the tiny pearl with her juices. With that done, he pulled her clothing back up and re-fastened her jeans.
Once more hiding nearby, Pyotr started time. Julia moaned aloud and gripped the stroller she was pushing as her knees went weak.
Maria smirked. “Must be the hormones, lucky girl.”
Julia bit her lip and pushed her hair back from her face. “I guess so. Maybe I should go home and take a nap.”
“Don’t even think of it!” Maria punched Julia’s arm. “Enjoy the sun and whatever is going on in your pants! And if it’s contagious, cough on me a little.”
“You sure are naughty for someone who doesn’t want sex,” Julia remarked.
“I never said I didn’t want sex,” Maria replied. “I’m just tired of Jack and the way he paws at me.”
“Well why don’t you talk to-”
Julia was cut off mid-sentence. Pyotr approached the women, this time eyeing Maria. Not only had she given up on her husband, but she was lewd as well. Perhaps she needed to learn a little lesson about being careful what you wished for.
Her clothes were a little baggier than Julia’s. It made sense, since her body was a little baggier than Julia’s too. Still, Pyotr thought, she wasn’t ugly or anything. There was no reason she shouldn’t have a healthy relationship with her husband. He pulled her shirt up and off, revealing a stomach slightly less pudgy than he’d expected crossed with angry stretchmarks and a pretty decent-sized pair of breasts strapped tightly into an unflattering bra.
The bra had little velcro pads at the top of each cup to hold the front padding in place. Pyotr pulled one open, revealing Maria’s breast and a puckered nipple that was more brown than pink. Maria seemed full of surprises.
Pyotr sucked on Maria’s nipple for a few seconds, kneading her breast. He stopped when he started to taste milk again. It was nuttier and not as sweet as Julia’s had been, but he supposed there was a lot of variation in that between women and wasn’t terribly curious as to why. Leaving the bra open, he knelt down and worked the zipper on her slacks.
Maria’s panties were unsurprisingly plain. Also unsurprising was the dark brown bush – “bush” was the only word for it, really – obscuring Pyotr’s view of her nether-regions. Spreading her thighs a little and pushing the flesh back, he was able to see her pussy; she was already glistening wet. Evidently Maria had gotten in the mood ahead of him.
Pyotr pushed back skin and fur, revealing her clit, and lightly flicked it with his fingertip. “If you were a little more tidy, I might use my tongue,” he teased, “but for you, fingers will be enough, I think.” He stroked Maria’s entrance slowly, a little more firmly than he had with Julia. After all, this was about punishment, not experimentation. There was less need to hold back. He turned his wrist and inserted a single finger inside her, but only halfway, then removed it again and replaced the clothing she had been wearing. He left the one bra cup uncovered.
Maria grabbed onto Julia’s arm when time started again, almost falling over. She shook all over, then gasped loudly. “Oh shit, I think I caught it!” she said in a hushed tone. “I was kidding!”
Julia frowned. “Maybe we should sit down.”
The women sat on a park bench and chatted some more, first about pregnancy hormones and their strange effects, then later about their babies, soon forgetting about their strange episodes. Pyotr waited patiently nearby, letting his mind wander back over his new ideas for quantum uncertainty. His attention was pulled back after a minute by Julia’s voice in his earpiece.
“Hey Maria,” she said, “your tit is leaking.”
Maria looked down at herself. There was a wet spot there, where Pyotr had left her nipple exposed to the fabric of her shirt. Maria shoved an arm up under the shirt to fix the bra, chuckling. “Thanks,” she said. “Velcro must be wearing out.”
Deciding once again that enough time had passed, Pyotr again froze and approached the women. He pulled them both forward on the bench, then lifted their hips and removed both of their pants and underwear.
With their legs spread before him, both women looked very inviting; Julia more so, of course. He started there, stepping in front of her and leaning over her body, smelling her perfume hanging in the air around her as he unbuckled his belt. In seconds he had his pants down and was easing his engorged cock down into Julia’s waiting pussy.
The temptation to just use her, to fuck her the way he had Anna before, was almost overwhelming, but he held back. Instead, he slid in slowly, groaning as her flesh parted around him, pressing inch by inch until their hips met. He rotated his pelvis slowly, pressing in every direction inside her, and reached down to rub her clit with his thumb, then slowly pulled out again.
Kneeling down, Pyotr gazed into the gaping opening he had left in his wake. Using the flashlight on his phone, he stared deep into Julia’s pussy. He had never seen in such detail what the inside of a person looked like; it was really fascinating. He could even make out the little pucker in the back where her cervix was, beyond where not long ago a human had been created.
Pyotr considered Maria. He didn’t want her to get off; he wanted to tease her. On the other hand, he cared considerably less about measuring her reactions and ensuring her comfort. Standing again, he moved between her spread thighs and rubbed the head of his cock below her soft tangle of hair until he felt himself start to slip inside her. Then he grabbed her by the hips and, with a single thrust, buried himself within her.
Maria’s flesh offered more resistance under the harder, faster movement. Pyotr moaned in pleasure, bracing one hand on the back of the bench and groping her breast through her clothing. He pulled up her shirt, yanking open first one and then the other of her bra’s cups, and squeezed at one of the fleshy mountains while his hips began pumping in and out of her.
On a sudden whim, Pyotr pulled out and yanked Maria down off the bench. One of his hands stroked himself swiftly while the other grabbed and lifted one of her breasts toward him. A bead of milk was stuck to one nipple, but it soon disappeared under a burst of an altogether different white fluid as Pyotr shot his cum at close range onto her skin. Moving quickly, he shifted over to her other breast and did the same; when he was done, her brownish nipples were covered in pearlescent white goo, with a light chain of droplets in the air between them.
Pyotr pushed her breasts back down to a more natural shape, then closed the bra over them, leaving the evidence of his presence in place. Even if Maria noticed it, she would never guess at what it really was. He pushed her aside and sat on the bench next to Julia, catching his breath and looking up at the bright summer sky, drifting into the sort of nap that only someone who truly has all the time in the world can ever enjoy.
The sensation of sleeping and then waking up at the exact same moment was disorienting. It took Pyotr a moment to remember where and when he was, but then his eyes landed on Julia’s bare legs and hips and it all returned to him. Maria hung in the air, legs still spread, looking like she was about to fall ungracefully on her ass. From this angle, he could see the glistening opening between her legs, still stretched wide from his carefree use.
The sight of both women, spread and ready for him, undoubtedly still warm from his previous presence, was enough to make Pyotr’s cock wake up and shift in his pants, but he put the thought aside for the moment. Before anything else, he had another observation of Julia to make.
It was interesting, Pyotr thought, that mastering time travel came with such thorough knowledge of how to put on women’s clothing. Handy, but interesting. He returned both women to where they had been sitting; an unknowing observer would never realize they were both stretched open, nor that Maria’s bra was full of cum.
Actually, an observer might be just the thing. Looking up the path, Pyotr grinned. That same kid on the skates had been coming up from behind. He was sort of far back, but that wasn’t an issue for someone with control over the primal forces of the universe.
Using a variation of the same motions that would unfreeze a single person, Pyotr instead unfroze everything around the two women. They sat, inconspicuous but completely immobile, while the sounds of nature and man flooded back into the world.
Pyotr waited, sitting in the grass on the other side of the path, until the skater got close. Then, with a flick of his wrist, he unfroze the two seated women.
Maria reacted first, throwing back her head and moaning shamelessly. Her hand clamped down on Julia’s thigh, and her hips bucked and squirmed, seeking a lover who wasn’t there.
For her own part, Julia managed to remain more composed. Her hand gripped Maria’s and squeezed until the knuckles went white, and her neck visibly tightened as she strained not to let the flood of sensation push her over the edge, taking a series of short, shallow breaths and biting down on her bottom lip.
The kid, startled by the sound and the sudden erotic motions of the women on the bench, lost his balance and again stumbled off the path. His arms and legs flailed comically, and he caught himself with both hands on a lamp post, sliding down to his knees, staring back at them with eyes that seemed as wide as dinner plates.
Maria was still squirming on the bench, one hand groping her own breast, when Julia regained composure and gave her a sharp elbow in the ribs. “Huh?” she said, looking around. “Oh, shit. Uh, listen, I… I gotta go.” She tried to stand up, failed, then tried again, using the bench’s armrest to pull herself to her feet. Julia stared open-mouthed as her friend rushed off with the handle of her stroller in one hand and a phone in the other, probably already calling to make sure her husband was at home.
Pyotr waited while Julia recovered. She had been close that time, but hadn’t gotten off, and it showed. Her face was flushed and she kept looking around, probably worried that someone would notice her condition.
After a couple minutes, her baby started to wake up, snapping Julia out of her daze. She got up and took the stroller in hand, walking toward a small parking lot. Pyotr followed, still listening in on her as she cooed to the child.
“Yes, we’re going home,” Julia said in a mother’s soothing voice. “We’re going to have a nap, and Mommy’s going to have some alone time.”
Pyotr raised an eyebrow. “Alone time” might be something pretty interesting to observe. He watched as Julia unlocked her car, a sensible little blue sedan. She loaded the baby into a car seat and got in, turning over the engine.
Pyotr considered his options. It would be easy for him to follow the car, walking along behind and stopping time whenever it got too far ahead, but really he just didn’t feel like that much effort. Instead he stopped it as she started rolling and got inside, closing the door softly and hiding on the floor of the backseat.
Julia’s house was only a short drive away. Pyotr snuck out of the car as soon as she pulled into the garage, hiding behind the car and following behind her when she opened the door into her home. It occurred to him that a person with this power would have a pretty easy time stealing things, and he took a moment to be glad that nobody unscrupulous was in control of Jeremy’s remote while he pulled out his phone to record a video for later observation.
The house was simple but cozy, almost a perfect image of a small family atmosphere. Julia took the baby into a nursery painted in an exciting mix of primary colors, then walked into the adjacent bedroom and sat on the bed, pulling open the buttons of her blouse one by one. Pyotr hid in plain sight, sitting on a chair behind her and ready to stop things if she looked his way.
She shrugged out of the blouse and pushed off her pants, then reached back to unfasten her bra. She pulled it off with a sigh of relief, bringing her hands up to slowly rub her breasts. “Relaxed fit my ass,” she muttered, touching the red line on her shoulder where the strap had been biting in.
Laying back on the bed, Julia again massaged her breasts, then slid one hand down the front of her body. Her fingers slipped under her panties and she almost immediately began breathing faster. Her hand moved, stroking and circling, and she let out a little moan.
A door slammed, startling her into sudden silence. She listened for a moment as footsteps echoed from the front door, along with two voices. “Shit,” she whispered, rolling off the bed and grabbing a loose sweater from a nearby basket of clean laundry.
She pulled her pants back on over her already moist panties and hurried out to greet the visitors. Pyotr stopped time and left as well, finding a good place to hide in a hall closet, standing between the coats and looking out a crack between the doors. The phone no longer had a good view, so he stopped recording.
“You’re home early,” Julia said, walking up to one of the two men by the door and kissing him.
He wrapped his arms around her and smiled. The husband, then. “Yeah,” he said with a shrug. “The mall was a bust. I’ll just order the parts we need.”
“Alright, then,” she replied, disengaging from him. “I see you brought Brett with you. Are you boys hungry? I can make some lunch.”
“No Ma’am,” the other man said. “We’ve got this.” He held up a bag of groceries.
Julia looked confused. Her husband laughed. “Relax, baby,” he said. “We’re gonna make lunch today. You just take a break. Where’s the kiddo?”
“I just put him down, but I was going to check in on him.”
“You shouldn’t check so often. You’ve got the monitor. All you’ll do is disturb him.”
“I know,” Julia said with an apologetic smile, “but it makes me feel better.”
The three adults exchanged some more pleasantries before splitting up, the men heading to the kitchen and Julia back to the nursery. Pyotr waited a moment, then followed Julia.
“Goddammit,” she said quietly, pressing her back to the door as soon as it was closed. “All I needed was another few minutes…”
“Minutes I have,” Pyotr said in between moments. He stood in front of Julia, rubbing his chin thoughtfully. “I suppose it is cruel to not let you feel relief, is it not?”
Julia was looking down at the floor. Pyotr gently tipped her chin until she was staring into his gaze instead, light glinting off her dark eyes giving her a sultry look. He ran a hand through her hair, feeling himself getting harder by the second.
Her loose clothing came off easily. Pyotr stood her in the middle of the room and peeled off her already-moistened panties, then paced around her slowly, considering her. He let his fingertips trail over her breasts, her back and ass, and her stomach, finally moving behind her and sliding his fingers down to stroke her pussy.
Pulling her hair to the side, Pyotr kissed Julia’s neck. He rubbed her slowly, gently spreading the wetness around, making sure to touch every inch of her exposed slit. His fingertips probed, opening her just a little and teasing her inner lips while his free hand cupped and squeezed one breast and then the other.
His cock was a steel rod against the supple flesh of Julia’s ass. Stripping off his clothing, Pyotr pressed his hips up against her, stroking himself slowly along the warm canyon of her rear. He had to move both hands to her hips to hold her steady, but the sensation was worth the effort.
Julia’s body leaned forward a little from his movements, and Pyotr stepped back to get a better look at her. She stood with her legs close together, almost as if teasing him with her ass, flashing her openings at him.
“Fuck it,” he said, stepping up and sliding himself inside her. Julia’s pussy was hot and slippery, needing almost no pressure to swallow his cock whole. Pyotr pulled back on her hips, groaning in her ear and grinding his hips on her ass before pulling back and thrusting in once more.
What a world it was, he thought as he started fucking Julia’s frozen body slow and deep. Of all the random chances that could occur, all the encounters, it had led to this: him buried deep inside of a beautiful woman, helping her to feel relief without her even knowing it. What would he be doing now if even one thing had been different? If he had eaten more at breakfast, would he have found someone else who needed his help?
One of his hands moved around her, rubbing her clit and pressing in on her pelvis. Pushing in, he could feel the little gateway at the back of her passage. He thrust harder, pulling Julia in against himself, and moaned in pleasure as the impossibly tight passage to her womb began to open to him.
It was that moment, when his cock pushed into Julia’s cervix, that Pyotr figured it out. If Julia didn’t check on the baby, it would sleep longer. By observing, she interfered. Heisenberg’s principle, applied on a larger scale. But she felt better disturbing her child, even though it could lead to a worse situation in one possibility.
“Holy… fuck,” Pyotr whispered, stopping where he was, holding Julia’s hips tight against his own. It was as if a light had turned on in his head. “Of course!” he said more loudly, pulling back and thrusting again. “It’s so simple!” Another thrust, and the echoing sound of his hips slapping her ass. To think, the answer had been right in front of him.
Pyotr knew how to do it. He’d solved time travel.
He bent Julia over a changing table, pumping faster and faster into her. His excitement at finally solving the puzzle came out as enthusiasm for fucking the woman before him, losing himself in the mix of elation and sensation.
“Ohh God,” Julia moaned. She contracted tight around him, arching her back and gripping the table. “Oh fuck yes!”
Pyotr hadn’t even realized he was going to unfreeze her. He’d just done it. It only seemed fair that she, the mother of time travel, should share in the moment of his triumph. And now that she was awake, exposed to all the things that had been done to her, Julia was cumming hard. The silent room filled with the competing sounds of her moaning and the fleshy impacts, both getting louder by the moment.
Her pussy gripped and rippled around him, and Pyotr found himself unable to stop. Grabbing Julia’s hips tight, he slammed into her. His whole body shuddered, and he could feel himself pumping his seed directly into her core.
As soon as his mind cleared, Pyotr froze Julia in time once more. She had been just about to try to look back at him. He pulled slowly out of her, then used some wipes from the table to clean them both up as best he could. He pulled Julia’s clothes back on, but left her bent over the changing table, leaving as unseen as he had arrived.
It was tempting to stay around, to help Julia have a wonderful night of passion with her husband. But not now; now, Pyotr had planning to do. Time may have yielded herself to him, but Science waited for no man.
Besides, he could always come back sometime. After all, he had all the time in the world.
