KEEP YOUR EYES ON THE ROAD

Summary:

A credit card, a limousine, some bottles and weed and they're off to Las Vegas for the weekend. Couldn't resist fucking in the car, high on drugs, it seems.

Marty's almost looking forward getting punched by his step-dad for it.

Notes:

I got off SO MUCH while writing this, you have no idea. It made me want to drink so bad, but all I allowed myself to get was Pepsi and this porn. So should you.

More dark lore and an OC that... actually feels a little too much like self insert cause I'm such a pervert.

Enjoy, you freaks <3

(See the end of the work for more notes.)

Work Text:

"I got raped by one of Dad's friends the other night," Marty said casually, sipping the rest of the champagne. It was warm now. "It was so lame, you should teach them how to do it, I barely screamed." He was so dizzy that he lay against Doc's arm in one of Biff's cars he'd borrowed for the evening. They were both in the back seat of this limousine on their way to Las Vegas for the weekend. Marty had stolen a credit card and wanted to treat them both. Never mind that he would get beat up for it later. “Plus, he wasn’t even that good.”

Doc had a joint pressed to his lips and slowly nodded at the dizzy teenager's ranting.

Then Marty stole the joint to take a puff and kissed the scientist's cheek in apology. "Pop another one."

"Are you sure? You've been through this one pretty quick, and there's still two hours to go." He looked over at the chauffeur and crossed his eyes as if asking for confirmation.

"An hour and forty-five minutes, sir." Charles replied.

"That's-that's more than enough for this and sex," Marty took a long drag and urged his friend to open a second bottle of champagne that was still in the ice bucket, "then we can have even more drinks." He was thirsty for a lot more alcohol in his veins, and he was getting cranky.

Doc sighed, staring at the dizzy boy with a smug look on his face, "Leave me some, I struggled to get this, you thief." He took the joint back and pinched the teen's face.

"Aw," Marty massaged his cheek, a grimace on his lips.

"Mr. Tannen's going to notice all this, Marty." The chauffeur ventured.

"Yeah, I hope he does. And I hope you tell him I'm about to get fucked in it, too, right?" He stared directly into the young driver's eyes through the rearview mirror and licked his lips.  "Besides, you agreed to take us there for what I'm paying you. Discretion, remember?" The young man swallowed his saliva and Marty deliberately squeezed his own crotch in a provocative way. Charles' eyes were back on the road.

“Yes, that’s right. I’ll do as you say.” 

“Stop messing with that guy, Marty,” Doc finally cracked open the champagne and handed it to the drunken teen, a joint hanging between his lips as he spoke, "Here, your bottle. I'll roll another, you want your own?"

"Naaah, I'll steal from you, I'll stick to the champagne, thank you very much."

"Fine, however you want it, baby boy." Doc took his little plastic bag of weed out of his pocket and opened a small metal box. "I got this, though." He showed it to the teenager, whose eyes widened in surprise.

"No way! What's in them?" Marty picked up a colorful pill with his free hand, having a hard time focusing his eyes on it, but trying anyway, which gave him a headache.

"Dunno," Doc started rolling a fresh joint, finishing the other one still on his lips. "I stole it from one of your guys last time." He winked at Marty and the teen laughed.

“Damn, that’s heavy, Doc. We’re playing Russian roulette with it?” 

“If you want, pick your favorite.” 

The car was full of smoke, the leather was sure to stink of weed and tobacco later. The chauffeur silently rolled down the window.

Marty dropped one of the blue and white pills into his empty glass and poured champagne over it. He watched as the pill became half effervescent. "Wow, I've never seen that before."

"Hm. Yeah, this is going to be great," Doc commented, picking up the same one, but not even bothering to put it in his own glass, he put it on his tongue and chugged from the bottle.

"Well, first of all, Doc, you- that’s rude." Marty snatched it back from him, "Secondly, h-how dare you not cheer with me, damn it." Marty followed with his glass and decided it was indeed easier with the bottle, so he took his first sip from it. It somehow tasted better with the weed still filling his lungs, making him spin a little more. This was sure to be an interesting cocktail in their veins.

He lay back and leaned his head against the old man. Doc's arm went around the boy's hips, pulling him closer.

“Yeah, hmm… I know what’s that stuff.” Emmett laid his head back and exhaled. He took a moment to absorb the sensation and smiled at himself. "There's definitely ketamine in there. Sorry to tell you, baby boy, but you're going to be soooo soft you won't even feel my hand on your body."

"Ah shit." Marty swore under his breath, already feeling far too mellow for his own liking. "No fun when I'm so stone I can't feel shit."

"Hm. Here." Doc handed him the new joint, "Can't get any worse now."

"Fine." Marty picked it up and motioned for the lighter.

The street lights on the highway to Las Vegas were now like flickering LEDs. Charles was told to turn up the radio.

They were doing 70 on the road, but it slowly felt like they were going up to 90 or 100, and Marty squinted at the lights outside the window.

"Kicking in yet? Or are you so wasted you can't tell?" Doc wondered, noticing the teen's confusion.

“Uuuhhh… I-I-m not sure…” Marty sat back on his part of the seat and stretched out. “I’m like… shaking and melting at once.” He gave his joint back to the scientist. 

"I see. Not just ketamine, but some kind of kick... makes sense." He thought about it for a while, then took the bottle out of the ice bucket. "Hey, Marty."

"Hm, yeah?" he still stretched his fingers, feeling kind of numb.

"Do you think I can come like that?"

That was such a stupid question for Marty. He scoffed. "Yeah, of course, I can make you come with anything in your head, duh." His hand asked for the champagne. "Why, wanna find out?"

The old man gave him the bottle, "I was really just wondering, you can suck me off at the hotel later tonight."

"What if I want to do it now?" Marty scooted over, a bright, innocent smile curling his lips. He was so high already.

"You can't even feel your body. I bet you're just wondering how long you can last with my cock deep in your throat before you pass out from lack of air since your gag reflex is jack shit now."

“Mmmmmmmaybe, but you’d love that, huh?” He straddled the man, still holding the bottle. Marty's free hand roamed over the old man's chest, "I'd love to die like this.” He struggled to keep eye contact with him, everything inside him was shaking, blurring his vision and turning his limbs to mush.

"Kiddo..." Doc pulled him closer around the waist and kissed his neck. His fingers dug into Marty's flesh through his clothes, drawing a small moan from him. Then more kisses followed, Doc even sucked on the skin.

"Fuck," Marty laughed, "I can't even feel that anymore, I'm so trashed."

"I know, I can tell." Doc replied in a half whisper. "I bet I can't even get you hard."

Marty shook his head in the most drunken way possible. He giggled and fell back against Doc, wrapping his arms around him.

The low hum of the car behind the radio was lulling, but they both felt like they were on fire, even though they weren't horny. It was a cocktail of everything that was messing with their senses.

"You know... after much thought, I think I'd like you to suck me right now." Doc admitted, gently squeezing the boy's thighs.

"Now we're talking." Marty removed his shirt and kissed the man on the lips. "A little treat before all the treats in Las Vegas, this is the kind of day I like."

There were better ways to do this, better times or places, but Emmett couldn't deny his pet's wish to please him, especially in such a fancy setting. Damn, this kid had the life: sex, money, drugs, and all the real shit.

"Go on, get down on your knees." Doc cooed, lips against the boy's skin. "I'll feed your hungry hole."

The mischievous grin on the teen's face turned into a bright smile and he was really happy that the man had agreed to use him right here and now, as high as he was. Fuck, he loved being used like a fleshlight when he was stoned.

"Give me the bottle back, you earn it once I cum down your throat."

Marty complied and handed him the champagne while kneeling in the space in front of the man's parted legs.

"Let's see how much of a show you can put on while high on ketamine, weed, and fancy champagne." The man unbuckled his belt with one hand and drank from the bottle with the other.

Then he left the rest of the tasks to the boy's hands and mouth, watching as his expertise instinctively executed the steps despite the dizziness.

Worthwhile and rewarding training. And Marty was like a dog anyway, if you gave him a little treat afterwards, he'd follow any instruction as long as he got something. And being Doc's little cockslut was all he wanted most of the time.

Doc took another swig from the bottle.

“How the hell did you get half hard on K, Doc.” Marty commented, grasping his growing cock. "I can't even have a quarter of that, and I was sitting on your lap." That mostly meant 'I imagined you deep inside me, fucking me mercilessly against the leather seats.' But he was right, it was a skill to be able to get hard when drunk.

Emmett wasn't sure...it could be the chauffeur pretending that that wasn't happening in his car, witnessing him raping a drunk boy younger than he was; and not just any drunk teenager, but Biff Tannen's kid. Or maybe it was just the way Marty was staring at him with those hungry eyes of his. Fuck, yeah, all right,  it got him way too hard,  the whole lot of it.

"I haven't even begun to touch you," the kid complained now, "am I really that hot when I'm high?" That was the last thing he said. Next, Marty stuck out a glistening pink tongue that lovingly slid along the tip of Doc's cock. It was warm, warmer than the interior of the car filled with weed smoke 一one of the joints was still in the smoke tray, and both of their skins were now sweating from the drug. The leather slid under Doc's hands. 

The teen's dilated pupils stared at him like 8 balls, his mouth was so wet the old man knew it would slide right down his throat if he pushed him down on his shaft. He was getting way too high himself, because now he was getting dizzier every time the boy sucked a little harder on the gland. Hell, Marty looked adorable doing it, eyes closed, hand cupping his balls, sucking like it was his favorite lollipop, and Doc just knew he could completely hallucinate the taste of one just by mimicking the motion. Now he dared to wonder if his juice would taste sweet to the boy.

"Just right, baby boy, keep sucking." Doc brought a hand up to ruffle the teen's hair, holding it gently. He took another swig from the half-finished bottle in his hand. Outside, they came to the outskirts of L.A. There were even more lights from the streets, casting flattering shadows on the teenager kneeling before him. He would fuck him hard later.

Maybe Marty couldn't even taste anything anymore, he always said everything tasted like cardboard when he was drunk enough, his tongue got so numb he couldn't even feel pain when biting it. Well, they were about to find out if ketamine would make it easier to stretch the boy's throat all at once instead of gradually. Emmett was looking forward to this part. Maybe he wouldn't even gag from the cum pouring down his throat... hm. At least Marty's sore throat had completely disappeared along with the numbness; he never even complained tonight.

The old man threw back his head and enjoyed the slow bobbing of that warm mouth on his dick. Marty was doing very well for his current state, it was delightful. Doc was also much more sensitive from the weed, so he didn't know if Marty was really doing well or if he was just enjoying the light touch of fingers on his dick and getting off from it. He would have to find out.

But now the teenager looked even deeper into it... the drug, he meant. He worshiped that dick as if it fed him, you could tell how much he put into sucking it. Marty was sweating now, his bangs plastered to his forehead; Doc ran a hand through his messy hair, pulling it back. Marty looked up at him, the dick popping out of his lips, saliva and pre-cum dripping from the tip.

Emmett could have forgotten the boy had blue eyes, maybe he did. What the fuck was in that pill?

"Want me to swallow or you wanna save it for later?" Marty asked, idly licking down the base before sucking on a ball.

"I'll think about it." The old man replied, stroking the boy's disheveled hair; he brought the bottle back to his lips, trying to forget his own dizziness. His eyes met the chauffeur's... Doc scoffed, looking smug now, "Keep your eyes on the road, boy. Unless you want to join in? I wouldn't mind another hoe." Marty whined, apparently not appreciating the thought of having to share Doc with anyone.

You could see the blush on the young man's cheeks as he looked ahead, avoiding the rearview mirror as best he could. He, too, might be as high as the two of them by now.

"You can take it now, baby, what are you waiting for?" Doc grew impatient, genuinely wondering why Marty was taking his time to enjoy edging the man. Doc’s fingers locked into the strands that were now guiding the boy's head.

Marty pushed his hand away, but it came back with more force. It didn't matter, Marty couldn't feel shit anymore. He tried to complain, annoyed, "Doc, you don't have to hold一"

“Hands off, kiddo, you’re not allowed to use them. Now open up.” 

Marty obeyed, sticking out his slick tongue, eyes closed, looking like a whore now; he was. "You love being used like a toy, don't you?" Doc earned a needy whimper when he didn't move the boy's head closer to his cock. "Yeah, fuck..." He drank more. "Are you ready, baby boy? Ready to choke on my cock for the next minute?"

Another high-pitched moan and some saliva fell on the leather. The teenager craved to be face fucked. The drug had made him so needy, maybe the second part was finally kicking in, even Doc could feel himself throb harder now.

“Fine, have it, you freak.” He pushed Marty's head onto his length and pushed it all the way down until the boy's nose brushed his pubic hair. “Ahhh一 Yeah, God, your throat feels so good when you’re high.” Emmett groaned, head falling back against the headrest. 

The lack of air made Marty delirious, and by the time he was rewarded with some, his eyes were blurry, he was drooling so much he almost choked on spit as he swallowed air.

He almost couldn't hear the music on the radio anymore, it was like he was sinking underwater, he heard a whistle coming from his head. But honestly, the few brain cells that were still working normally in the teen's head were confused as hell with everything that was going on there.

"What now?" Doc frowned as he watched Marty take a second to come back to reality; he did not like it, the boy was a hole and a hole only. "Do you want your bottle or not?"

Marty gulped hard, nodding eagerly, looking up at the champagne the old man was holding, salivating at the thought of the sparkling taste rolling across his tongue, the bitter end at the back of his throat一 fuck, he would do anything for that bottle.

"Well," Doc picked up his length and gave it a tug, "then don't just sit there."

He couldn't hear the music anymore, but Doc's voice was wired into his brain, eating it alive like a worm. Anything the man wanted from the teenager, he would get, not because Marty wanted it, but because his body had a Pavlovian response to that voice, fearing abuse if it did not provide satisfaction. And all the drugs just made Marty's brain follow that body, knowing exactly what to do.

He opened his mouth again and sucked on the cock in front of him. He was a slut. But he loved it now. At least he was useful, that's what he kept telling himself, even though he knew it was all deeply wrong. It was rewarding in a way, he preferred being a cockslut to someone he liked.

Marty forgot to breathe and choked as Doc grabbed his hair and pulled him back against his pelvis. His nose was crushed and the cock twitched deep in his throat. Fuck, he was really going to puke.

"Shhh, relax your throat, baby boy, you can take it." Now Emmett was pressing down on the boy's neck, circling it with his fingers, squeezing it gently. Marty made uncomfortable moans, trying to get out of the uncomfortable position. He couldn't, and he knew it.

His tear-stained face was swollen and he was about to faint when his trembling hand against the man's calf made Doc release his throat in one fell swoop. Marty immediately swallowed a lump of air, coughing spit and snot; he was sobbing. "J-Jesus... Doc..." he exhaled, his throat aching from the impossible stretch.

“You’re barely trying, do you even want that champagne?” The old man rolled his eyes. He took another gulp. "Come on, I still have to come, don't just sit there complaining, this was your idea, commit to it." He motioned for the boy to come closer so he could manhandle him.

Mary obviously obeyed.

"Open up, baby," he was asked. He obliged. His eyes shone over his swollen red face; he was still struggling to breathe properly. "You must be nice and open now, right?" rough fingers grazed his cheek, sliding across the tongue that hung low like a dog. "All stretched out and wet for me." Doc leaned down close to the boy's messy face and whispered, "I'm going to use your throat as a cock warmer until we get there, you hear me?" Marty whined. "I know I lied, I won't give you the bottle, but you can earn one back at the hotel tonight if you be a good boy."

"I'll be a good boy, Doc," the teenager replied.

"That's what I like to hear." Marty earned a kiss on his damp cheek and the man tucked his finger into his sweaty hair. "Now..." he sat back against the expensive leather, legs wide apart, "better lather up that cock nice and shiny, it's going to sit in your throat for a while."

 

There had been moments in Charles' career as Biff Tannen's employee when he knew it couldn't get any crazier, and the man himself had convinced him of that. But tonight it was on another level... He didn't know what it was about these two, but they certainly didn't care about the consequences when they put on such a show for his eyes.

It was usual, he concluded. Everyone who'd ever been close to The Boss was like that, he wasn't clean either... if he was honest with himself, watching was the best part of the job. The number of times he could get off watching Tannen fuck those prostitutes in the backseats of every fancy car he drove... absolute angels giving him winks and kisses in the rearview mirror...

But tonight it was none of that.

No, tonight it was his beautiful wife's youngest son: Marty, being used like a toy by the town's mad scientist, who'd made him his little thing. It had been a while now, Charles knew everything by now, he was always the one driving Marty around, and more than often to Doctor Brown's place when the boy didn't go on his own. He'd promise the kid to keep his mouth shut, in exchange for more money than his salary provided. Bribed by a child, if he had to bet on it...

The worst part of it, leaving aside the pedophilia of it all, was how sick Charles felt as he enjoyed watching the boy being raped over and over again under his gaze. And Brown loved being watched, too, the chauffeur noticing the glint in his eyes every time they crossed his own in the rearview mirror.

Fuck. He was hard now.

He exhaled and took a left turn to another exit of the highway.

 

"Do you have any idea how pretty you look down there, baby boy?" rough fingers stroked the teen's head like it was a dog's fur; he moaned around the cock in his mouth, stretching his throat to almost unbearable pain he couldn't feel anymore... too drugged to feel shit, uh?

Doc had almost finished the bottle by now, he should have been dead drunk, but fortunately whatever they'd taken in their drug Russian roulette kept him fully aware of everything. It was the strangest mix of substances he'd ever done, and he couldn't figure out what was on the other side of the pill, but it probably could have been cocaine, if not stronger.

Whatever, he wasn't here to ponder this... but he couldn't help but think一

Damn, it was really messing with his brain, wasn't it? How was Marty feeling? He was behaving so well today, the mixture was perfect for him... turning him into a mindless whore.

Hm, Emmett will think about synthesizing it all into a single drug; easier to administer.

It had been 38 minutes, he knew, he counted it. For 38 minutes that boy had been cockwarming him like a perfect fleshlight. Sucking on that dick like a starving slut. Impressive.

Almost as impressive as Doc not letting himself come down the kid's throat.

Hm. He should, though.

He continued to stroke the hairy head with gentle fingers, longing for the boy between his legs. Jesus, he was perfect. Then he downed the rest of the champagne and dropped the empty orange bottle on the floor of the limousine, grabbing that head with both hands.

"Ready for my load, baby boy?"

The bloodshot-eyed teenager nodded eagerly, not taking the cock out of his mouth. His cheeks and lips were so swollen and pink now. Yes, he was starving for it.

Good.

"Very good." Doc repeated, aloud this time.

Next, Marty's head was pushed down against the old man's pelvis and he took a few seconds to appreciate how deep he could go into that tight, warm throat… feel it tighten and stretch around him all at once... yeah, shit一

It twitched, Doc groaned, digging his nails into the teen's scalp to hold him still, panting hard as his cock pumped warm cum down Marty's throat and now he gagged at the amount that flowed down his stomach.

Marty's hand hit Doc's leg several times, but the old man didn't care an inch. He let him choke on it until he'd swallowed every last drop.

"Take it, baby, you love it, don't you?" His hand still held his head firmly against his crotch, but the fingers were soothing and kind again, Marty was so disoriented. His eyes shed endless tears of pain and exhaustion, but Doc didn't care. “Thaaat’s right, all of it, ah- fuck一” Emmett bit his own lip to the bone, riding his own orgasm as the boy's throat tightened around his length.  "Swallow it all, Marty, be my good boy."

And a few more seconds...a few more tears running down those pretty cheeks and he was freeing the teen's head.

Marty coughed snot and semen that dripped on his face, shirt, and leather seats all the way down to the carpeted floor. He refused to let go, and Doc chuckled at the shaky, sobbing teen in front of him. 

He had swallowed it all. Impressive. Oh, he was getting better by the day.

"Very well, if I may say so." Doc smiled; Marty gave him a death stare.

He tried to retort, but he was out of breath, deciding he'd rather catch it before he defied the man. Marty wiped his chin with the back of his hand. He was way too high to even see him clearly, his brain was in a fog and he came on the spot when he choked on Doc's cum, his body too dazed for shit.

"You should clean up your mess, don't you think?"

Oh, Marty wished he could talk right now.

Doc leaned down and grinned at him, grabbing his bruised jaw, "What's the matter, you fighting back again? You're too high to do anything right now, Marty, don't even get me mad when you've been doing so well so far."

Marty caught the fingers gripping his jaw and tried in vain to remove them.

Doc kissed his forehead and took back his sweaty curls, "You still want a drink later, right? Go on now, clean up." He pushed him against the leather seat between his legs and asked him to lick it clean like the dog he was.

Who was Marty to disobey him now? He was too far gone to go back now, there was no escape...there never had been.

"Eyes up, look at me." Doc ordered.

Marty stuck out his tongue and licked the sperm off the expensive leather, his eyes staring at his friend and captor.

A locked door. No running-away, there is no use.

"Don't swallow yet." Doc brushed a finger across the swollen lips. "Show me, baby boy." And Marty opened his mouth, cum sliding down his tongue. Doc added his finger, pressing on the dirty tongue. "Suck it, then swallow."

The fucking locked door was in his head now, Doc had won his bet and turned Marty into his puppet. There wasn't even a key anymore, it had burned in the pits of hell a long time ago, and Marty was pulling on the chains on his own.

Got himself addicted to the abuse.

He swallowed, moaning at the bitter taste he could finally feel on his taste buds, not having it poured directly down his throat.

"Good boy, you earned your bottle tonight." The old man praised him and kissed him on the lips.

Fuck, Doc was right…

He loved it sooo much.

I'll be back with regular porn for a while after this. I do have the draft of the true beginning of this AU in the making, but I need something softer in between because... this one will be heavy.
