The Tire Mechanic Checked More Than My Car’s Tires

“Shit, not again,” I muttered through clenched teeth, gripping the steering wheel as the car vibrated like it had a life of its own. The shaking climbed up my arms and into my teeth. I managed to pull into the first shop I saw on that ugly stretch of road outside town: a ramshackle warehouse with a flickering neon sign that read “El Tano Tire Shop.”

The smell of hot rubber and oil hit me in the face the second I got out of the Audi. I was late for a meeting, I was wearing my best heels and a silk blouse that had cost more than I cared to admit, and the last thing I wanted was to step onto that grease-soaked floor.

A man came out from the back, wiping his hands on a black rag. Tall, thin, skin weathered by years in the sun, wearing a worn-out T-shirt with the name “Damián” embroidered on the pocket. His eyes ran over my body without even trying to hide it, lingering a second too long at my neckline.

“What’s wrong with it, ma’am?” he asked. His voice was rough, gritty, like he dragged the words out of himself.

“I don’t know, it just started shaking out of nowhere,” I said, crossing my arms, irritated. “Check the tires, but fast. I’m in a hurry.”

Damián crouched beside the front wheel and ran his open hand over the tire tread, slowly, almost affectionately. He pursed his lips.

“Here’s the problem. They’re soft. Too soft.”

“And what does that mean?”

“Means they’re no good like this, ma’am,” he said, pressing his thumb into the rubber. “A tire without the right pressure bounces wrong, wears out all kinds of ways, and gives no pleasure to drive on. You feel every bump.”

I frowned. Pleasure? What kind of answer was that?

“I mean driving,” he clarified, as if he’d read my face, with half a smile. “Feeling like the car’s flying. But don’t worry. I’ve got tires that are really worth it. Come on, I’ll show you.”

I followed him to a covered area in the back, where the tires were stacked like giant black doughnuts. He tapped one with his knuckle.

“This one’s hard. Takes whatever you give it and doesn’t soften up.” He pointed to another stack. “And these are top of the line. They’ve got a special inner lining that protects them, makes them last, and keeps them soft to the touch. Want to feel?”

Before I could refuse, he took my wrist and guided my fingers toward the inside of a tire. The fabric was silky, much softer than I’d expected. I felt a shiver that had nothing to do with the cold in the warehouse.

“Sometimes the problem isn’t the rubber,” he went on, lowering his voice, “it’s what’s inside it. You know what they put in them to make them last?”

He took a jar off a shelf. Inside was a thick milky liquid that moved heavily when he turned it.

“This. Fills the pores, seals the cracks, and leaves them like new. Firm and full.”

I couldn’t stop looking at the jar. The whole conversation had a double meaning I didn’t want to understand, but my body understood it perfectly. My throat had gone dry and, instead, between my legs I could already feel a warm wetness soaking my panties.

“And how do I know if they work?” I asked, and my voice came out softer than I wanted.

“You have to test them, ma’am,” he said, taking a step toward me. “But first we need to check that the whole assembly’s in order. The car is one whole thing.” His eyes dropped again. “You, for example. Nice tires you’ve got. But are they at the right pressure? Or are they a little soft too?”

And then, before I could react, he raised his hand and laid it on my chest, right at the edge of my bra. I froze. His palm burned through the silk.

“Mm,” he murmured, massaging slowly. “Soft. Need pressure. Someone needs to work them properly so they firm up.”

***

I should have slapped him. I should have grabbed my bag and run out to report him. Instead I stayed there, my back against a stack of tires and the smell of rubber wrapping around me, while his other hand moved up to reach for my other breast.

“Feel that?” he said. “With a little pressure they show more. They bounce better.”

A moan escaped me, a mix of panic and a desire that embarrassed me.

“We shouldn’t…” I managed to say.

“Of course we should. It’s a safety inspection,” he whispered into my ear, while his thumbs found my nipples through the fabric and pinched them until they stood hard like little pebbles. “We’ve got to test every tire. The car’s and the lady’s.”

He unbuttoned my blouse with a skill that scared me. Button by button, unhurried, looking me in the eye. The lace bra gave way when he yanked it down, and my tits were left bare in the gloom of the shop, nipples standing up and pointing at his face. He looked at them with a hunger I had never seen in my husband.

“What a pair, ma’am. Nice and full, nice and white. Looks like nobody’s worked them the way they should.” He crouched and caught one nipple in his mouth, sucking hard, pulling it between his teeth until I let out a shriek. He took the other between his fingers and twisted it, with no tenderness at all.

I arched my back against the rough rubber and bit my hand so I wouldn’t scream. His hot, rough mouth bounced from one breast to the other, sucking, biting, leaving them red and shining with saliva. I felt every tug straight in my cunt, as if an invisible thread connected my nipples to my clit.

“Look at them standing up,” he murmured against my skin. “Don’t tell me you don’t like it, ma’am. These tits are asking to be eaten.”

While he devoured me, his other hand slid down my stomach and slipped under my skirt, pushing it up little by little over my thighs. He pulled my panties aside with two fingers, without asking permission, and sunk his hand between my legs.

“And now the final test,” he murmured. “Let’s see if you’re well lubricated inside.”

His fingers found my clit, swollen and soaked, and a ridiculous sound escaped my throat. He started rubbing it in slow circles with the pad of his middle finger, while with his thumb he spread my cunt lips apart.

“Look at that. Dripping like the good tires. Ready to roll.”

He shoved two fingers into me and I jerked all over against the stack of tires. He started in and out slowly, curling his fingers inside, searching for a spot I’d thought was a myth until then. When he found it, my knees buckled.

“Ah, there it is. You’ve got a nice firm little tire in here, ma’am. Let me work it for you.”

He finger-fucked me there, standing among the tires, his fingers buried to the knuckle and his palm slapping my clit with every thrust. His other hand kneaded my tits roughly, tugging on my nipples. He spoke in my ear with that same mechanic’s cadence, explaining a repair.

“That’s it, ma’am, that’s it. Look how wet you’re getting. Hear the sound it makes.” The sloshing of his fingers going in and out filled the warehouse, obscene, impossible to deny. “This little cunt was neglected, wasn’t it? It needed someone who knew how.”

I felt the orgasm rising like a wave, fast and humiliating. I grabbed his shoulders and came on his fingers, biting my lip so I wouldn’t shout, trembling all over against the rubber.

“Good girl. Nice and wet.” He pulled his fingers out, shiny and soaked, and passed them over my lips before putting them in his mouth and sucking them with a disgusting noise. “Delicious. Now for the real test.”

He yanked my skirt down, ripped off my panties, and threw them onto the greasy floor. He turned me around against the stack of tires and bent me forward, my hands braced on the black rubber. I heard his belt buckle, the sound of his zipper, and then the heavy slap of his freed cock against my ass.

I felt it before I saw it: thick, hot, throbbing between my cheeks. He rubbed the tip up and down over the slit of my cunt, soaking himself with my juices, while with his other hand he squeezed one breast from behind.

“Let’s see if you can take the ride, ma’am,” he growled, and drove into me in one single thrust, all the way to the hilt.

I let out a strangled scream. He filled me so suddenly I felt split in two. He stayed still for a second, with his cock buried to the balls, letting me get used to the size.

“See? That’s how you fill a tire. Nice and tight, ma’am. Nice and hot.”

He started moving, first slowly, pulling almost all the way out and slamming back in with a wet smack. Then faster, harder, until every thrust pinned my tits into the rough, stinking rubber. His hands held my hips in place, marking me with his grease-stained fingers.

“Take it, ma’am, take it against the rubber,” he panted. “You like the tire guy’s cock? Say yes, say it.”

“Yes…” I moaned, my face mashed against the tire, smelling rubber and sweat.

“Harder.”

“Yes, I like it, I like your fucking cock!”

He drove into me faster, brutally, while one of his hands moved down to rub my swollen clit. He talked dirty to me, treated me like just another tool in his shop, and I hated myself for how much I liked it. He called me a whore, told me I was his new tire, that now he was the one who’d keep me at the right pressure.

I felt the second orgasm building, deeper, longer. I clenched around his cock and came, moaning like a bitch in heat, my thighs trembling and my cunt dripping onto his balls.

“That’s it, that’s it, squeeze me good, suck my cock with your cunt,” he growled, and four more thrusts later he finished inside me with a roar, emptying himself to the last drop. I felt the heat flooding me like a final surrender, stream after stream of hot semen filling me while he stayed buried against my ass, trembling.

He pulled out slowly and I felt the cum start running down my thigh. He straightened his clothes as if nothing had happened and handed me a clean rag.

“Clean yourself up. Your tires are ready.” He mounted a new tire on the Audi, and when I came closer still trembling, he added in a low voice: “The car’s tires are hard now. Yours, though, are worn out. And now they’re mine. Come back whenever you want another inspection.”

***

I drove the next few blocks in deafening silence, my panties in my bag and a stranger’s semen still sliding between my legs, soaking my skirt. I spent three days unable to think about anything but the smell of rubber, Damián’s rough voice, and the delicious humiliation of everything that had happened in that warehouse. Every night I masturbated in the bathroom, biting my hand so Andrés wouldn’t hear me, imagining myself bent over the tires again. Andrés, my husband, noticed I was spaced out.

“What’s wrong with you, Mariana? You’ve been acting weird since Monday,” he said one morning at breakfast.

Panic clenched my stomach. I couldn’t tell him the truth. But the excuse came out on its own, woven from the same heat that had been eating me alive.

“It’s the car, love. When I took it to the tire shop, the guy told me about special linings to make the tires last longer. He said they were top quality.”

Andrés looked up, interested, always so practical.

“Oh yeah? Are they worth it? If they’re good, have him put them on. I’d rather spend on that than get stranded on the road.”

My husband’s answer was exactly the permission I’d been looking for without daring to look for it. The perfect justification for my own filth.

“I didn’t ask much,” I lied, my heart pounding in my chest. “I was embarrassed. But if you say so…”

“Go ask properly. Come back and tell me. If they convince you, have him put them on all four wheels.”

***

That’s how I found myself once again in front of the neon sign for “El Tano Tire Shop.” This time I’d put on a shorter skirt, no stockings, and a new pair of panties that were already soaked before I even got out of the car. Damián saw me arrive and a slow smile, the kind that says he already knows everything, spread across his face.

“Mrs. Mariana. Did the car start shaking again, or did something else loosen up?”

My cheeks burned, but I held steady.

“My husband wants to know more about those linings. The ones that make the tires last.”

Damián let out a low, filthy laugh.

“The husband wants to know? Well, look at that. Men always want to protect what’s theirs. Come on, linings aren’t for just anyone.”

He led me to a tiny office in the back, crammed with catalogs, smelling even thicker of rubber. From a metal drawer he pulled out two objects that stole my breath: two dark latex sheaths, long, but they weren’t empty. They were full, swollen with a milky substance moving heavily inside them.

“These are the linings,” he said, holding them up like trophies. “You put them on, work them good and firm, and fill them to protect the rubber inside. When you’re done, they look like this. Proof of a job well done.”

He brought them closer. The latex was warm, and through it you could see the thick liquid shifting. I understood perfectly what they were: two used condoms, full of semen, kept like samples.

“And what do you do with them after?” I asked, fascinated and disgusted at the same time.

“Test them, of course. You have to verify the quality. And the best way is straight from the source.” He paused, loaded with something dark. “But first I’m going to put a new lining on that tire of yours. On your knees, ma’am.”

I obeyed. My body moved out of pure submission before my mind could argue. I knelt on the cold floor, my skirt bunching up around my thighs. Damián opened his pants slowly, enjoying every second, and pulled his cock out. He was already hard, thick, with a red, swollen head dripping a clear bead at the tip.

Up close it was even bigger than I’d felt inside me. My mouth went dry.

“Take the lining with your mouth. Put it on yourself.”

He tore open a little packet with his teeth and handed me the condom. I took it between my lips, tasting latex, and moved toward his cock. I pressed the tip against my mouth and started rolling the sheath down, pushing it with my lips and tongue, sliding it down the whole length with a clumsiness that seemed to excite him even more.

“That’s it, ma’am, lower. With your tongue.” He grabbed the back of my neck and shoved, driving his cock down my throat. I choked and tears sprang to my eyes, but he didn’t ease up. “Suck it good first. With the lining and all. Get it all nice and wet.”

I started sucking his sheathed cock, bobbing my head up and down, helping myself with my hand at the base. He set the rhythm by tugging my hair, forcing me to take him all the way down every so often, enjoying it whenever he heard me gag. Saliva ran down my chin and dripped onto my breasts, which had already slipped out of my blouse on their own.

“What a good mouth the married lady has. Looks like they taught you well at home, how to suck. Does your husband know you’ve got a whore’s mouth?”

Then he yanked his cock out of my mouth, lifted me by the hair, and bent me over the metal desk. The cold steel burned my tits. He shoved my skirt up to my waist, ripped off my new panties, and stuffed them into his pocket like a trophy.

“Look at that. Dripping again. This lady gets wet just walking into the shop.”

He spread my legs open with a shove and sank into me in one brutal thrust, all the way to the hilt. I howled against the desk. The latex made him feel different, a little slicker, but just as thick, just as invasive.

“That’s how you test a lining, ma’am,” he growled into my ear, driving harder and harder. “Feel how it protects you inside while I shove it in hard?”

He fucked me mercilessly, grabbing my hips, my hair, my dangling tits. The desk shook and thudded against the wall with every thrust. He talked dirty into my ear with phrases that humiliated me and, at the same time, pushed me to the edge.

“Your husband wanted them to put linings on you, didn’t he? Well, that’s what I’m doing. The best one of all. And I’m going to keep this one too, add it to the collection. So when another customer comes in, I can show her Mrs. Mariana’s lining, filled to the brim.”

He shoved two fingers in my mouth for me to suck while he fucked me, and with his other hand he went down to rub my clit. I couldn’t even think anymore. I pushed my ass back to take him, begging him for more with my hips even though my mouth couldn’t speak.

“Come for me, ma’am. Come with the tire guy’s cock inside you. Squeeze it tight, make me finish.”

I came screaming against the metal, my cunt convulsing around his cock, dripping inside the condom. Damián grabbed my hips with both hands and drove into me four, five more times, brutal, all the way, and finished inside the latex with one last shudder, emptying himself completely. I felt him swell, hot and heavy, deep inside me, inflating the condom with liters of hot cream.

I stayed bent over the desk, panting, legs shaking and another man’s semen weighing inside me, while he withdrew slowly. He removed the condom carefully, tying a knot in it, and left it on the desk beside my face so I could see it clearly: the swollen, warm, milky sheath, identical to the ones he’d shown me in the drawer.

“Done. New lining installed,” he said, straightening his clothes. “This one goes into the collection, with your name on it. Tell your husband the car’s tires are safe. Yours, ma’am… yours won’t ever be the same again.”
