One evening, we were in my room after class. Axel had already changed into his basketball jersey and shorts when he tossed a folded set at me--an extra pair from his bag.

“Go change,” he said, jerking his chin toward the bathroom. “I hope it is not too big for you.”

I didn’t own anything like that. I wasn’t a regular player, and he knew it. But still, I wore them. They were loose on me, a little too big, but they stayed on well enough.

It had been an abrupt invitation. One of his teammates had backed out last minute, told Axel yesterday he couldn’t make it, and I was apparently the backup. Just a body to fill the court. But I was thrilled. At least, he thought of me.

“Are you sure we’re wearing these during the drive there?” I asked, tugging awkwardly at the oversized jersey.

Axel glanced over.

“Yeah. Why not? It’s a 30-minute drive. The courts are not very far”

I didn’t argue, but I couldn’t shake the feeling that I looked ridiculous next to him. On him, the jersey fit like it was made for him. On me, it felt like a costume.

So there I was--in his passenger seat as usual. This time, I left my backpack behind, carrying only my wallet, keys, and ID. I slipped them into the glove compartment, just like I’d done a hundred times this month.

“Do you want something on the way?” he asked. “It’ll be pretty late when we get back.”

How thoughtful of him. I nodded with the excitement of a kid heading to Disneyland.

“Alright ... we can have tacos then,” he replied.

A few minutes later, he pulled over to a big parking lot. There was a gas station in one corner, and right next to it was a small taco truck. There was a Mexican behind the counter, working the grill. Apart from a small queue in front of it and a car in the gas station, the whole lot was quiet and seemed deserted.

Axel parked the car a short distance from the food truck, killed the engine, and took the wallet from the central console before handing me a few bills.

“Four for me ... no drinks,” he said.

“What about me?” I asked. It was better to ask him than to assume and get it wrong.

“Get whatever you want,” he said, waving his hand dismissively. “Hurry up ... we don’t have much time.”

I nodded and bounced.

By the time I got to the truck, there was only one person left in the queue. It did not take long for him to get his tacos, and I gave the taco man my orders. “Six tacos and a Coke”

From where I stood, I could see the back of the sedan. Axel had rolled the windows halfway down. One arm hung out the driver’s side lazily, the wind catching his fingers like he had all the time in the world. His seat was reclined just a bit more than usual, and from the angle of his head, he was probably scrolling his phone.

A few minutes later, tacos were ready. The guy behind the counter put them in a sketchy foam container. The Coke came in a plastic cup with no straw. I juggled everything in my arms on the way back, already regretting not making two trips.

He opened the door for me from the inside, and I got into my seat. I handed the to-go box to him and put my Coke in the cup holder in the central console.

He opened the box, his eyebrows going up. “Didn’t you get them separately?”

“You didn’t ask me to, and I am only having two of them,” I said.

“I thought you had common sense,” he replied.

He made me hold the box. So, I balanced the box on my right hand between us over the central console. He pulled my hand closer to him, signalling me that the box should stay closer to him.

With my other hand, I grabbed a taco and brought it to my mouth. Since tacos weren’t exactly made for eating in a car, it took some careful maneuvering not to spill anything. I managed to finish both without making too much of a mess--just a small drip of sauce on my chin, which I wiped away with a tissue.

No sooner had I grabbed my Coke with my free hand than he asked me to hand him a piece of tissue. So, without putting the Coke down, I awkwardly snagged one with my little finger and tried to bring it to him. But on the way, I accidentally knocked the entire box of tacos onto his lap. Panicking, I instinctively used the tissue in my left hand to wipe at the sauce--only to make things worse as my Coke tipped and spilled all over him, soaking his pants and staining his jersey.

It was a disaster, and every swear word in the book came flying out of Axel’s mouth--idiot, cunt, retard, pussy, faggot--you name it, he said it, each one landing like a slap.

I apologised to him, not wanting to be struck. Even when I used up all the tissues in the car, it was not enough to dry him.

“Fuck,” he said, pushing away my hands that are trying to wipe his jersey clean.

He looked over himself, perhaps assessing the damage. “I can’t go to the match wearing this,” he said before turning towards me in anger.

Then, there came the command. “Strip”

I couldn’t believe my ears. Is he telling me to strip? I must have looked like a deer in the headlights.

“You heard me,” he said, a finger pointing at the back seat. “You are gonna give me your clothes, and you are doing it here”

When I didn’t move, he leaned in with a warning: “Or would you rather have Emma strip in your place?”

I shook my head ‘no’ and meekly climbed into the back of the car. Meanwhile, Axel left the driver seat and opened one of the rear doors.

He stood in front of me, blocking most of the view, but I could still make out the gas station employees in the distance behind him. No one was paying attention to us, of course. They were all busy tending to a growing line of cars at the pumps. “Start taking them off, Sammy,” he ordered.

My hands shook as I pulled up my jersey and took it off. I handed it to him, making him smirk a little. “Go on ... we don’t have all day.”

I was reluctant to take off my shorts. Being pinned and groped against a wall was one thing--but crouching half-naked in the back of his car, stripped to my underwear before my bully, was another entirely.

He gave me that usual look of disapproval, and I immediately clutched the waistband of my shorts, feeling the familiar flush of obedience wash over me. Without another word, I slid them down to my knees in one swift motion, trembling slightly. He learned over, wordless, pulled off my shoes, then finished the job himself--tugging the shorts off completely.

Now, I was down to my underwear--a small, vulnerable blue pair--and completely at his mercy.

I thought that was the end of my humiliation--but I was wrong. He wasn’t finished.

“Go on,” he said, voice low and firm. “Give me your underwear too. You’ve soaked mine.” The words sank in slowly, burning with shame. He wasn’t asking. He never did.

“Please,” I begged, my voice cracking. “Please ... not this one. I’ll be completely naked without it.”

Instinctively, I dropped to my knees, clutching the hem of his jersey like it could anchor me. It was the universal pose of desperation--head bowed, fingers trembling, pleading for the last shred of dignity I had left.

“Can’t we just go back to the dorm and change there?” I asked, my eyes searching his face for mercy I already knew wouldn’t come.

Axel was not impressed. He took my hands off his jersey and pushed me back. “Last time I checked, you did not own any jerseys.”

“Please ... I have shorts and T-shirts in my room.”

“You mean wasting another 30 minutes? We are not going back, Sam. You are going to hand me that underwear here and now.”

And just like a circus animal obeying its trainer, I did exactly as I was told.

I hooked my thumbs under the waistband and pulled it down in one swift motion--like ripping off an old bandage, fast and shameful. The air hit my skin, and all I could do was kneel there, bare and obedient.

He took it from me without a word, adding it to the pile of my clothes in his arms. His eyes raked over my exposed body, a spark of excitement in his eyes. I instinctively tried to cover myself, but he stopped me with a simple command: “Hands behind your head.”

That was an unnecessary command. He had no right to see my private parts. He had already got the clothes he needed, and there was no further need to humiliate me. But at the same time, I knew perfectly well there was no use hoping he’d be reasonable.

“What have we got here? An exhibitionist, huh?” He said with a laugh.

He must’ve seen it--my cock, hard and twitching between my legs. It throbbed with the humiliating thrill of being forced to strip, the arousal betraying every bit of shame I felt.

“I’m gonna have fun with you, Sam. Really,” he said, amusement dancing in his eyes. “But that’ll have to wait--I’ve got things to do.”

He gave me one last look, lingering just long enough to make me squirm.

“I’m going to change in the gas station bathroom. You’ll stay exactly like this. Don’t move. That’s your punishment.”

With that, he closed the door, leaving me in the car. From the inside, I could see everything. I could see him walking towards the gas station, the taco truck at a distance, some people looking for their car in the parking lot.

I didn’t dare move.

“The windows are tinted, Sam,” I muttered. “No one can see you.”

That’s what I told myself to stay calm. In reality, anyone passing by from the front could still see me--the windshield wasn’t tinted. It was illegal in my state. Luckily, the seats blocked most of my body, and no one would expect someone to be naked in the backseat with their hands behind their head.

At least, that’s what I hoped.

Let me tell you. Time drags painfully slowly when you are naked in a random parking lot, forbidden to move an inch. I could feel the warmth of the evening sun beating down on the car. It would be an hour or two before the sun set. Sweat clung to my scalp and dripped down my forehead.

When I saw Axel disappearing into the gas station bathroom, a little voice appeared in my head. “You can relax now, Sam. He can no longer see you.”

But I did not move. I did not move because there was a bigger voice telling me that he would somehow find out about my disobedience and that I would come to regret it.

I could already picture my lovely sister, Emma, stripped of her blouse, her skirt, even her bra and panties in the back seat of his car, pleading for her dignity while being coldly told to place her hands behind her back, denied even the smallest chance to shield her breasts and pussy.

My thoughts were interrupted by Axel’s return. Panic set in because I could not see the stained jerseys in his hand. Although I did not bring up the subject matter earlier, I had the expectation that he would allow me to wear his stained clothes once he changed out of them.

Without the pile of clothes in his hands, he walked faster. He opened the front door and got into the driver’s seat.

“Where are your clothes?” I asked, astounded.

“I am wearing them,” he said, looking at me through the back mirror.

“I mean the stained ones,” I said, my mouth gaping open in surprise.

“Aww, those? I tossed them in the bin. They’re unwearable now.”

“What am I supposed to wear now?” I asked.

“Nothing,” he said, glancing back at me. “Your little dick’s still hard, huh?”

The engine roared to life as he threw the car into reverse. My heart pounded like it had just been slapped.

“What do I do?” I shouted in panic. “Everyone would see me.”

“You can hide here,” he said, nodding toward the narrow space between the passenger seat and the dashboard.

The car eased out of the parking space. In just a few seconds, we’d be back on the crowded streets of downtown--where there’d be far too many eyes not to notice a naked guy scrambling to the front seat.

I only had a small window to move, and I had to make a decision fast.

I clambered over the center console, my bare skin brushing against something sticky--leftover sauce in a discarded takeout box. My dick grazed it, making me wince, before I dropped into the cramped space like a hunted animal.

Only then did I realize my mistake.

My head was facing the passenger door.

Which meant my ass, completely bare, was on full display to Axel.

It was up in the air, perched awkwardly on the front edge of the center console, right in front of the gear stick. I could feel the cold metal just brushing the side of my butt, leaving only the narrowest gap for Axel’s hand to shift gears.

As he’d promised, I was pretty sure the setup kept me hidden from public view. The side windows were tinted. The dashboard blocked the view through the windshield. No one could see me--probably.

The car pulled onto the main road, and the city swallowed us whole.

Engines groaned in different keys. Cars pulled up alongside us. Horns blared at random. Each sound hit like a jab to the ribs, rattling my nerves.

When the buses thundered past, the entire chassis seemed to shake. The vibrations rolled through my knees, up my elbows, into my belly ... and all the way down to the tip of my dick.

My ass jolted with every rumble, and I kept having to readjust my perch, shifting again and again in a losing battle for balance.

“Stop squirming your ass, Sammy,” he said casually. “Or I’ll give you something to clench about.”

That was all it took. My asshole clenched instinctively, bracing for something--a pen, a finger, anything--to breach me without warning.

Fortunately, that something never came.
