Headlight Sparkle? Twilight Carkle? Tailpipe Sparkle?
Flash Sentry exited the front door of his suburban middle-class home, shutting it behind him with a heavy click. He breathed the fresh summer air, feeling like a new man, as he smiled brightly at the prospect of what he was about to do. He licked his lips as he gazed over at his new car. Well, the car itself wasn't new, but its paint job was; the sides were a faded purple with four stripes running over the top, from bumper to bumper, the two outside lines a dark blue that flanked two thinner strips of deep purple and hot pink. On the hood and side of the car were depictions of Twilight Sparkle as a pony, with her name emblazoned across the side in neat white letters, starting from the front wheel well.
He had only known her briefly, and then only as a human at Canterlot High. However, because she was originally a pony, he decided to request her to be painted in that form. And it wasn't as if she wasn't attractive as a pony; those features served to make her more exotic and, if anything, even more desirable.
The paint job was done as his 18th birthday present from his parents. It had been painted that way for nearly a week, but this was finally his first time alone with it. He could already feel his bulge, tight against his blue jeans, as he looked at it. No, at her.
Running a hand through his electric blue hair as if trying to look his best, Flash Sentry bit his lower lip and walked along the narrow concrete path to the driveway.
"I-it's good to see you again, Twi," he said anxiously. He felt a bit silly talking to a car, but with nobody around to judge him, he continued. "Ever since I met you, there's so much I've wanted to do to you. Take you on a nice date, treat you, hold you... kiss you." His breath was picking up and his thoughts were a hurricane of emotion. He tentatively reached an arm forward and placed a hand on her hood, shivering as he did. Did he... feel her shiver too? Surely not. Surely it was just his own movements and his mind playing tricks on him.
He walked along her, running his fingertips over the smooth metal exterior, up and over the passenger side windows, then down to come to rest on her trunk. His eyes followed the stripes that matched her mane's colors, down and down, slowly, past her bumper, and his eyes rested on her shiny metal tailpipe. He looked away, blushing.
"S-sorry," he said bashfully. "I just couldn't help myself." She didn't seem to mind, however. Wait, she was a car, why would she mind? Flash Sentry shook his head and tittered anxiously. He leaned forward and rested his upper body against her trunk, arms spread wide, and hugged her. His erect member pressed against her through his pants, but he tried to ignore it for the time being. After all, he didn't want to jump straight into it, as that would just be rude.
He rubbed his cheek against the clean, cold surface and awkwardly tried to squeeze his arms against her. Suddenly, he heard two quick and loud chirps as though he had just pressed the 'lock' button on his key fob. Confused, he stood up and reached into his pocket and fished out his keys, looking at the little electronic device. Huh, probably just bumped it, he thought, then shrugged.
With a press of the 'unlock' button, he made sure the doors would be accessible, and circled over to the driver-side door. Flash Sentry pulled it open and climbed into the driver's seat. His tongue ran over his lips as he slowly inserted the key into the ingnition, feeling a small vibration as if the car herself was anticipating it. With a swift turn of the key, she started up, engine purring as she idled. She always sounded so sexy to him, even before she became Twilight. Now she drove him crazy. He reached down and pulled a small lever that popped the hood open, fully and uncomfortably hard under his jeans.
He climbed out easily and stalked to the front end, stroking her hood along the way. His hand reached under the cracked-open space and found the hood release. With a shudder of anticipation, he pressed it and pulled the hood up, gazing at her beautiful engine, vibrating in delight as it hummed.
"Ohh, yes," he said. He propped the hood open and unzipped his jeans, letting his meaty length flop directly onto her. Idly stroking himself, he removed his pants and light purple underwear (with Twilight's face on them, the flap situated exactly where her horn should be). "Mmmnh, naughty girl."
Flash Sentry took the opportunity to check her oil, and it looked good. He wiped her dip stick against his shaft for some especially intimate lubrication before putting it back inside her, then continued his slow, sensual stroke. To his surprise, she seemed to rev up slightly at that. But it didn't worry him; it turned him on even more.
Unable to wait any longer, he closed her hood and kissed it lovingly right on the pictured Twilight's muzzle, before walking around to her naughty end, bottomless with his pants left forgotten; he was still wearing his black jacket over his worn white t-shirt. And there was her tailpipe, quivering and excited. He got down on his knees and shuffled forward until his turgid member was lined up with the smooth metal pipe. A soft moan escaped his lips as he pressed into it slowly, the vibrations and warm exhaust feeling intense against his sensitive exposed flesh. She seemed to rev up again as he entered her, as if she was just as excited as he himself was. He was no longer questioning it, and simply went with it.
His thick cock was just small enough to fit, but wide enough to feel the vibrations and airflow, an especially intimate kind of feeling for him. He groaned as he bottomed out inside her, balls brushing against the shiny tailpipe. She revved once more. With a satisfied and cocky smirk, Flash Sentry pulled out and thrust inside her quickly, making her exhaust come faster, and vibrations more intense. Then he started thrusting in earnest, clinging with one hand to the rear wheel well, stroking the other over her sexy trunk.
"Mmmh, yeah, Twilight," he said as he made sweet love to his favorite horse girl car. "G-getting close!" His member throbbed deep inside her as he neared his limit. His thrusts became erratic as he reached the edge and was driven past it, and he grunted lewdly. With a sudden hard throb, his cock spewed his seed deep inside his beloved car's depths and her horn sounded, loud and long and clear, piercing the peaceful suburban silence. His member twitched as he injected her with more of his love. Suddenly, the trunk and hood both popped up and her horn stopped, replaced by her alarm, headlights and taillights flashing as she emitted a cacophony of beeps, chirps, and sirens.
As his orgasm passed, he collapsed backward onto his driveway, closing his eyes to shield them from the bright sunlight above. The car's alarm stopped sounding and they both basked in their post-orgasmic afterglow for a couple of minutes. Eventually, Flash Sentry sighed and tilted his head up to look at her again, a smile gracing his face. He noticed a wet spot under her where some oil had spilled and he giggled. Naughty girl. With a small grunt, he stood up to clean himself up (and then her).
From across the street, frozen in a mix of confusion, worry, some arousal, and even more confusion, was Mr. Cake. He had been on his way home from the hat shop, and was sporting a new fedora complete with a small Rainbow Dash figurine fixed to the top. The sight of Flash Sentry doing unspeakable things to his purple car had given him pause, however, and he ended up watching the whole thing.
"Well, I'll be damned," he said. "Guess I've seen everything now."
