Autonomous vehicles by the twenty third century should be possible.
Exploring Everything
Despite living in the modern era, Mutsunokami never rode inside a car, until this week. He plopped into the passenger seat and pressed buttons that made his door's grey window slide up and down.
"How come I can see outside the glass, but the glass won't let the outside see me?"
"It is tinted by a film," Sen said in the driver's seat.
Sen tapped her phone on the dashboard. He memorized the buttons she pressed to instruct the vehicle. Last time they were in this black car, they put groceries in the trunk and snacked on chocolate ice cream cones as the car drove itself back to the citadel. The breeze brushed his hair and face when the windows were rolled down. Technology took care of so much labour!
Sen inputted an address close to a marketplace. Then, the car rumbled and ran on its own. When it neared traffic lights, it halted and drove itself.
Mutsunokami tapped his sandals on the floor, pretending there were pedals. He raised his arms and curled his fingers around the air as if he gripped a steering wheel.
"Brrm, brrm." When the car turned, he steered his imaginary wheel to make a right. For eons, humans directed animals, ships, and trains for transportation. Now, they could do anything in this self-driving car without watching where their vessel went.
Mutsunokami leaned towards her phone. He pressed his arm along her lap to balance himself. "Can I tell it where to go next time?"
"Maybe." Sen tapped the screen and used her slim fingers to zoom in and out of the map; a dotted red line indicated where they were heading. She could input commands to redirect the car down another route and destination with a flick of her fingertips. "But tell me when you want to go, so I can join you."
The last thing anyone wanted was an accident.
"Right, right."
The car stopped at a red light. An elderly couple crossed the street with their brown poodle. No one outside knew who was in the vehicle. Sen and Mutsunokami could observe the whole world and no one would notice them. Touching Sen's thigh earlier, he realized they could do things they otherwise couldn't in public.
"Sen-chan, do people have sex in cars?"
"W-what?" A pink blush spread across her cheeks. Her reaction answered him.
Mutsunokami snickered. He wondered what positions were possible in this cramped space; he could sit on the backseat as she rode him, or take her from behind with their hands and knees on those leathery seats.
"I know this car sorta belongs to the Time Government, but how about it? They'll never know what we did in here." With his grin and gleaming amber eyes, coupling here seemed so easy.
Sen looked out her window, hand covering her mouth. Was she considering all the positions they could do? One day, he'd learn how she knew so much about sex, despite lacking experience before they became lovers.
Sen had seen porn of people fucking in cars, buses, and trains. When she was informed about the rented car, she wondered what sex would be like in it. If the Time Government found out about her and Mutsunokami fooling around in their property, they would deem her irresponsible. Then again, should she care about what they thought? She took Mutsunokami for rides because he enjoyed them. He had stared in awe when this car rolled up to the citadel for the first time and wanted to experience everything in it, including sex.
Sen turned her head towards Mutsunokami. He still looked at her, smiling, waiting for an answer. She touched her phone's screen, lighting it up. "We need to go somewhere private, Mu-chan."
"Let's go to the park! There's space we can hide at."
Sen entered the directions and the car changed course. Mutsunokami leaned forward to kiss her lips and chin. Her skin was soft as his lips left a trail of kisses down her neck. When he reached her chest, Sen parted her robe to expose her breasts.
"Whoa, look at you, showin' your boobs in public!" Mutsunokami said. At a red light, two people crossed the road.
Mutsunokami and Sen were one rolled down window away from exposing their secrets to the world, yet their lover was the only one with the privilege of seeing the other's form.
Mutsunokami tucked her seatbelt under her breast, lifting it up. He burst out laughing.
"There's finally somethin' that can hold your huge tits!"
"What about you?"
"Me?" Mutsunokami parted his robe to expose his chiseled chest. He extended his seatbelt and tried to shape it to outline his pecs. The belt grazed his nipple and rewinded as his chest wasn't ample enough to hold it in place.
Sen covered her mouth, stiffling a laugh. He really tried to get the seatbelt to mimic his chest's shape.
"Hm, your boobs are no match." Mutsunokami kissed her chest; he smiled at her soft skin. Her breasts bounced when the car drove over a bump. He sucked and licked her breasts as his hand reached between her red hakama; she parted her legs to let him rub her.
Mutsunokami latched onto her nipple. She cradled the back of his head, stroking his brown hair. She sighed under her breath as her nipples hardened and chest heated up as he sucked. She grinded against his hand as he rubbed her between her legs; the warmth from his palm spread on her.
A blue car lined up beside them. The driver couldn't see Sen and Mutsunokami, she reminded herself. They could do anything to each other in here.
"If they saw us," Mutsunokami said. "They'd think about how hot you are, Sen-chan."
"M-Mu-chan," she said. "Can I touch you?"
"Huh?" He smiled and swirled his tongue around her slicked areola. "Where do you want to touch me, Sen-chan?"
Her hand pressed his clothed erection; the bulge grew and hardened against her palm.
"Oh, you want my dick?" Mutsunokami straightened against his seat, pushed down his trousers, and withdrew his erection. Sen stroked his cock; it was so hot and firm thickening in her grip.
A passersby on the sidewalk strolled by. If only they knew Sen pumped Mutsunokami; their relationship and activities would be exposed to the whole world.
"That all you got, Sen-chan? Two days ago, you stroked my dick til I came." She had used a lot of lube to pump that messy, glistening cock. After he climaxed the first time, she jacked him off again; his thighs and bandages were covered in streaks of semen.
Her nipples were hard and breasts tinged with his heat and saliva. As Mutsunokami had sucked her chest, she wanted to return the favour. She leaned down and sucked his cock's head, bobbing her lips; he was too well-endowed to take him deep in her mouth. As his precum leaked out, salty on her tongue, she coughed and saliva rolled down his cock. She rested back against her seat to catch her breath.
"Well, you tried." He laughed and stroked his erection.
The car turned into a parking lot.
"We have arrived at your destination." The phone's screen flickered on.
"Thanks, phone!" Mutsunokami leaned towards the device. "Hope you don't mind us foolin' around."
As it was midday, they were alone in the area; nearby trees and bushes obscured them from view of the road.
Sen squeezed her hakama together. She wasn't ready yet. "It will be easier if we use the backseats."
"Heh, I was wonderin' how we were goin' to do this."
Sen was in the backseat, back pressed against a door, and legs spread as Mutsunokami licked her entrance and thumb massaged her clit. They left the door open; Mutsunokami's feet and footwear dangled outside. They could get caught as Sen's bare legs were up, one thigh gripped by Mutsunokami's arm. And yet, they weren't going to stop this liaison if someone spotted them.
"Ah!" Sen jolted as pleasure shot through her. His tongue touched a sensitive spot in her.
"You're gettin' wet." He lifted his fingers; they glistened with her clear fluids. "Are you ready for some cock?"
"Let me turn over." Her hands and knees were on those soft seats while Mutsunokami stood outside. She shuddered as Mutsunokami hiked her robe around her hips, squeezed her rear with calloused hands, and smeared her ass with their glistening fluids. He pressed his cock's tip at her entrance.
Mutsunokami couldn't help but gaze at their surroundings: it was trees, bushes, and an empty parking lot. No one was about, though a dog barked in the distance. "Should I finish this fast, Sen-chan?"
Sen squeezed around what little she had of his cock to answer him.
"Okay, I'll be quick." He snickered and straddled her hips. He started with shallow thrusts, lightly patting her ass. Sen gripped leather and pressed her forehead on the seat. His big cock thrust back and forth. His fingers, rubbing her folds and clit, dripped with fluids. Her thighs tensed as his dick pounded a sensitive spot. He angled his cock to hit that spot again and again.
Sen gasped against the seat as she squeezed his erection. Would they be brave enough to do this again? If this was the last time they ever coupled in a car, what could be done to make this encounter unforgettable?
"M-Mu-chan." She lifted her head.
"What is it, Sen-chan?" He stopped moving.
"...we could do it outside, on the car's hood."
Mutsunokami was still. They had plenty of sex on surfaces, like tables and kotatsu, though never out in public. He had to chuckle.
"Heh, where do you get these horny ideas?" He appreciated her perversions, nonetheless. He slipped his cock out of her.
Sen stood outside with only her untied white robe; it didn't cover her cleavage. Sen knew this was indecent, but she and her lover were preoccupied with experiencing new things. Wasn't their relationship all about exploring everything in and out of the bedroom?
"Huh, you really want to get fucked out here?" Mutsunokami hugged her. His warm body, from his chest, abs, and cock, pressed against her.
"Is there a reason why we should not?" This moment of bravery happened because of all the lewd things they dared to do inside this car.
"Good point." Mutsunokami lifted her up by the waist and lie her down on the car's black hood. "Let's go fast."
She parted her legs and he resumed fucking her. Under daylight, his bandaged abs tensed as he straddled her hips and thrust his cock in her. His arms flexed as he rubbed her clit and folds. His amber eyes were intent, watching her breasts bounce and her black hair splayed over the hood.
"Ah!" Sen placed a hand over her nub and rubbed with Mutsunokami as her climax came. Her legs curled around his waist and locked his hips against hers. She tightened around his erection as the pulses of pleasure ran through her; nothing else mattered apart from squeezing his cock.
Mutsunokami grinned as her legs kept him in place; no one, no matter their strength, escaped her grip. He leaned forward, pressing his defined chest on her big breasts. When he came, they embraced each other. The car hood's cold, hard surface pressed against her back as Mutsunokami shook and his heat and semen filled her insides.
As much as they wanted to remain like this, or make love one more time, they couldn't; they had to hide their activities.
They returned to the front car seats and lie back, panting, relaxing. Sen parted and pressed her legs together; her inner thighs were smeared in clear and white fluids. They had to return to the citadel, wash up, and change clothes. Then, they had to clean the car and spray scents. After that, they'd figure out when to fuck again in here; there were various positions to try out.
"Hey, Sen-chan, can I tell the car to drive us home?" He poked the smartphone; the screen lighted up with a white and green map waiting for directions.
"Of course, let me show you."
