Chapter 3
Fan Fiction Sex Story: Chapter 3 - This is a story I did for myself with AI, and the result was decent, so I thought I'd share. In "Back to the Future" everything works out fine the McFly clan. Better than fine, in fact - they work out swimmingly. Still, there are plenty of dark themes along the way, which as a PG Hollywood movie, it has to brush over fairly lightly. And since I have a dirty mind, I wondered: what if things had gone wrong for the McFlys, in the worst, most twisted, and darkly-erotically way possible...?

The DeLorean screamed out of 1955 in a blaze of temporal fire, and when the lightning strike finally deposited Marty McFly back into 1985, the world he returned to had curdled.
Hill Valley looked much the same at first glance—same cracked sidewalks, same clock tower still stubbornly broken—but the air tasted different. Thinner. Meaner. He drove the borrowed truck through streets that felt narrower than memory, until the familiar turn for Lyon Estates never came. Instead, a weathered sign pointed toward the Shady Pines Trailer Park, its letters faded and pocked with rust. Marty’s stomach dropped as the truck bumped down the pitted gravel lane between sagging mobile homes.
His house—home—was a faded beige single-wide at the end of the row, its skirting bent and streaked with mildew. The porch light buzzed like a dying insect.
He pushed open the door and stepped into a haze of cigarette smoke and something sweeter, cheaper. The television murmured in the corner. And on the threadbare couch lay his mother.
Lorraine Baines—for that was still her name—looked up at him without surprise. She was forty-seven but carried the years like extra weight she had long stopped fighting. Traces of the pretty girl from 1955 lingered in the high cheekbones and the piercing blue of her eyes, but time and hard living had softened and coarsened her in equal measure. Her house robe hung open. Beneath it she was naked, breasts heaver now and spilling sideways, pubic hair an untamed thatch. She had one leg hooked high over the back of the couch, and a stranger—mid-forties, balding, tattooed arms—was thrusting steadily up between her spread thighs, cock ramming into a cunt that had evidently seen a lot of use in the intervening years. The wet, rhythmic slap of flesh loud in the small room. The man didn’t even glance at Marty.
Lorraine’s gaze met her son’s for a brief second. She offered a small, hazy smile, as if he had simply come home from school a little late. Her body continued to rock with each thrust. “Hey, honey,” she murmured, voice breathy but casual. “There’s leftover pizza in the fridge.”
Marty’s throat closed. He fled down the narrow hallway, shoulders scraping both walls, and slammed the door of what he prayed was his room.
Inside, he leaned against the cheap paneling, breathing hard. The space was cramped, cluttered with posters of bands he didn’t recognize and clothes that smelled faintly of laundry detergent and despair. He began rifling through drawers and shelves with the frantic focus of a man trying to prove the nightmare unreal. Old photographs. A few yellowed newspaper clippings. A battered shoebox of postcards from nowhere special.
The picture that emerged was uglier than he had feared.
Lorraine appeared in nearly every image—sometimes smiling too widely, sometimes with a distant, glassy stare—always with different men. There were no family portraits with a father. Only Lorraine, growing heavier and wearier with each passing year, her children orbiting her like uncertain moons. Marty found a copy of his own birth certificate. Father: Unknown. The same for Linda and Dave.
Jesus Christ, he thought, sliding down the wall until he sat on the thin carpet. What did I do?
From the living room came the stranger’s low, guttural groan as he finished. A minute later the front door opened and closed. Feeling like a coward, Marty stayed hidden until the trailer fell quiet again.
Dinner was served on TV trays in the living room because the kitchen table had become a permanent dumping ground for unopened mail and empty bottles. Lorraine had changed into a loose T-shirt and nothing else; the hem rode high on her thighs when she sat. Dave and Linda picked at their food with the bored resentment of people who had long stopped expecting better. Marty poked at lukewarm spaghetti, his nerves raw.
He tried to sound casual. “So ... I was thinking about Dad lately. You know. Whoever he was.”
The room temperature seemed to drop ten degrees. Lorraine’s fork paused halfway to her mouth. “Why you gotta bring that up at dinner, Marty?” Her voice carried the defensive snap of an old wound reopened too many times. “You think I got some fairy-tale story saved up? I don’t.”
Dave snorted. “Yeah, well, join the club.”
Lorraine set her fork down, eyes suddenly bright with something between shame and defiance. “Look, I was young and stupid, alright? Real stupid. After Marty I got my tubes tied because I wasn’t about to keep playing Russian roulette with my life. You kids are it. And I love you, but I ain’t gonna sit here and lie about knowing who knocked me up. I got no clue. None.” She laughed, a brittle sound. “Hell, I’m just glad I remembered their names long enough to get their phone numbers sometimes.”
She didn’t mention the Enchantment Under the Sea dance. Not once. No trembling recollection of parking, or Biff Tannen, or the abandoned barn. To her, that night had been swallowed by years of harder nights, folded into the general blur of bad decisions and worse luck.
But Marty could do arithmetic.
Dave had been born in late 1956. Nine months after that night in the barn. Four men had finished inside her. Four possible fathers for his older brother. The thought made Marty’s skin crawl. And if Dave’s paternity was a lottery with only four tickets...
He looked down at his own hands, at the spaghetti slowly congealing on his plate, and felt a wave of nausea so sharp he had to swallow hard. How many men had his mother been with in those chaotic months after the dance? How many loads had she taken while the trauma and shame and desperate hunger for any kind of affection spun her life out of control?
He couldn’t bear to calculate the odds for himself.
Later that night, after the others had gone to their rooms, Marty lay on his narrow bed staring at water stains on the ceiling. Outside, a dog barked hoarsely and somewhere down the row a couple was fighting. He pressed the heels of his hands against his eyes until colors burst behind the lids.
This was the future he had fought so hard to save. A mother hollowed out and opened to anyone who wanted her. A brother and sister who carried the anonymous DNA of strangers. A version of himself who had grown up in this tin can of quiet desperation. Maybe it would have better if he’d just never been born.
The morning light in Shady Pines Trailer Park was thin and unforgiving, filtered through dusty blinds and the perpetual haze of cigarette smoke that never quite left the walls. Marty woke early, nerves still humming from the night before, only to find the trailer sunk in heavy silence. Dave snored behind his closed door. Linda’s room was dark. From the narrow hallway he could see Lorraine sprawled on the couch exactly where he had left her the night before, robe twisted around her hips, one lolling breast exposed to the stale air. She did not stir.
Marty’s dresser was empty of clean shirts, so he pawed through his hamper. Almost the first one he came across was emblazoned with the Biff’s Auto Detailing logo. Evidently that’s where he worked. Pulling it on, Margy thumbed through the battered Yellow Pages until he found the address. Grabbing his skateboard, he slipped out. Maybe he could at least find something productive to do with his morning.
The ride across town felt longer than it should have, the wheels rattling over cracks in the pavement like accusatory knuckles. When he reached the car wash, the smell of soap and gasoline hit him hard. Biff Tannen leaned against the office doorway, older and thicker around the middle but still carrying the same swagger. His belly strained against a polo shirt embroidered with his own name. He took one look at Marty and sneered.
“Jesus, Baines. You ain’t even on the schedule today. What, you suddenly develop a work ethic?” Biff’s eyes narrowed with lazy suspicion. “Or did you turn into a little pot-head overnight? ‘Cause we can start doing drug tests around here real quick if that’s the new direction you’re headed.”
Marty’s hands tightened on the edge of his skateboard. Anger rose, harsh and sudden in his throat. “Look, you need to listen. I know you were hot for my mom back in high school. And I—” He paused, throat dry, while Biff eyed at him with exaggerated impatience.
Marty wanted to indict Biff with everything that happened, to call him on the carpet, to shame him. He wanted to throw every bit of it in Biff’s face: the dance, the barn, the photographs. But, when he tried to speak, the words weren’t there. The whole incident had just been too obscene, too awful, too hopeless. How could he talk about, out loud?
At last, Marty went on lamely. “So ... you know, why didn’t you ever help her out? Take care of her? I mean, like, after everything...”
Biff stared at him for a beat, then let out a short, unkind laugh that echoed off the concrete bays. He jerked a thumb toward a framed photo on the office wall: Biff himself, grinning beside a bottle-blonde woman in a too-tight dress and a surly-looking teenage son who already carried the shadow of his father’s jaw.
“I got smart and found myself someone with class,” Biff said, tapping the glass with one thick finger. “Not a trailer-park whore like Lorraine Baines. Sure, she was hot back then. And easy too—real eager once you got her going. But look at her now.” He shrugged, almost philosophical. “Anyway, you know as well as I do that me and the boys still stop by every couple weeks. Laugh over old times, give her a pity fuck if it seems like she needs it. Honestly, I do still enjoy sticking it in her, but what makes it special is how grateful she is. Spreads those legs like I’m about to give her a Christmas present. And really, what more can she hope for than that, kid?”
The words landed like punches. Marty felt the blood drain from his face. He turned without another word and fled, pushing hard off the pavement, the skateboard wheels screaming beneath him all the way back to the trailer park.
Lorraine was on the porch when he returned, smoking a cigarette in the weak morning sun. Her faded pink robe hung open, flapping lazily in the breeze and offering the entire row of trailers an unobstructed view of her sagging breasts and the dark triangle between her thighs. She didn’t seem to notice or care. A couple of neighbors glanced over, one shaking his head, but no one said anything. This was simply how things were.
Marty sat down on the cracked concrete steps beside her, trying not to look directly at her exposed body. The silence stretched between them until he could no longer stand it.
“Mom ... I remember once you told me about George McFly. You still think about him?”
Lorraine exhaled a long plume of smoke. For a moment her eyes softened, drifting somewhere far away. “George,” she murmured, and the name sounded almost tender on her lips. “Yeah. He was the one that got away. Sweet boy. Shy. I tried so hard to land him after ... well, after everything went to shit senior year.” She gave a small, bitter laugh. “But after those pictures got passed around ... God, everyone saw them. My classmates, sure, but teachers too. The pastor. My parents! Anyway, I guess I was too damaged. Used goods. He couldn’t even look me in the eye anymore. Packed up right after graduation and got the hell out of Hill Valley. Heard he did alright for himself in the city. Some kind of writer or consultant or something. Married a nice girl. Had a life.”
She took another drag, eyes distant. “Sometimes I wonder what would’ve happened if that night at the dance had gone different. If George had been the one to ... you know. But wishing doesn’t change much, does it?”
