Fan Fiction Sex Story: Chapter 2 - 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...?

Something about that moment when he positioned himself between her thighs—maybe way her skin was pricked by the matted straw and the cool night air, or the blunt heat of his erection pressing against her most intimate flesh—something about it finally opened the floodgates, and allowed a trickle of desperate words to spill from her mouth.
“Please, Biff,” she whispered, voice quavering even as her eyes burned with unmistakable hatred. “I’m sorry—I’m sorry I played hard to get. We can do other things. I’ll ... I’ll use my mouth, or my hands, anything you want. Just please, please not that. Not like this.”
The plea tasted like ash on her tongue, but she forced it out anyway, hoping some scrap of mercy might still exist in the bully looming over her. Biff paused, drinking in the sight of proud Lorraine Baines reduced to begging. A slow, cruel smile spread across his face, eyes glittering with satisfaction. He liked this—the way her voice shook, the way she humbled herself while still clearly despising every syllable.
“That’s more like it,” he murmured, voice thick with arousal. “But I don’t think so, Lorraine. I’m having too much fun.”
In one fluid motion he seized her wrists and pinned them to the straw above her head, his grip iron-hard. With his knees, he forced her legs wider apart, applying inexorable pressure. She gasped at the sudden, vulgar exposure—the way her body opened to him completely, her swollen, glistening pussy laid bare and vulnerable, the guarded secrets of her reproductive tract now fully accessible. The cool air kissed her there, underscoring how slick and shamefully ready her traitorous body had become. She felt exposed down to her soul, a crude caricature of femininity, rendered in the most primal and degrading way possible.
Biff drank in her anguish like fine whiskey. He shifted his hips, guiding the thick head of his cock to her entrance. Then, deliberately, savoring every second of her diminishment, he began to push.
Her body resisted at first, tight and unyielding. Lorraine whimpered, hips twitching uselessly beneath him. Then, with a sharp twinge that made her cry out, his glans breached her. The sudden intrusion sent a hot jolt through her core. She blanched at the cold, irrevocable knowledge: this brute had just deflowered her. Her virginity was gone forever, claimed in a filthy barn by Biff Tannen of all people.
Biff felt that same precise moment—the subtle pop, the sudden give—and his face split into a wide, triumphant grin. “Holy shit,” he breathed, half-laughing in disbelief and delight. “I popped your cherry! I hadn’t even thought about that ... Fuck, if you ever get married, I’m going to know that I got there first—and so will your husband.” The realization electrified him, pouring fresh fuel onto the fire already raging in his blood.
He began to press deeper, driven by raw need rather than any tenderness. Lorraine’s inexperienced cunt gripped him like a velvet fist, so tight it bordered on painful even for him. Progress was slow, measured by necessity; each incremental advance requiring steady, insistent pressure. He felt her inner walls spasm as they reluctantly stretched around his thick shaft. The exquisite clasp drew a low groan from his chest.
Lorraine’s breath came in short, ragged pants. She could feel every inch of him forcing its way inside her, reshaping her, claiming territory that had never been touched. The burning stretch, the heavy fullness, the humiliating wetness that eased his passage despite everything—she registered it all with a spinning mind that could not reconcile the reality. How did I let this happen? How is he inside me?
At last, with a final grunt of effort, Biff sank the entire impressive length of his cock into her. His heavy balls pressed against her, his coarse pubic hair grinding against her swollen clit, the broad head of his penis nudging against the deepest, most sensitive recesses of her body. They were locked together completely.
Their eyes met.
His were bright with gloating victory, the pure masculine triumph of conquest. Hers, wide and unwilling, brimmed with deepening self-loathing. A wave of hot satisfaction rolled through Biff as he savored the sight of her pinned and impaled beneath him. Lorraine, meanwhile, felt herself filled beyond comprehension—transfixed, speared, her body no longer entirely her own. The weight of him, the heat, the relentless pressure against every sensitive inch of her canal left her mind reeling. There were no answers for how this cretin had managed to bury himself so completely inside her. And the nightmare was far from over.
The lanterns painted the scene in warm, treacherous gold, their light flickering across sweat-slick skin and the restless shadows of the barn, as Biff began to move.
At first his thrusts were raw and deliberate, almost experimental. The thick length of his cock dragged against her insides with a chafing burn that made Lorraine’s breath catch sharply. Each slow withdrawal pulled at her tender flesh; each return pressed deeper, forcing her body to yield. She lay pinned beneath him, teeth clenched, trying to endure the invasion as a distant horror rather than something happening inside her own skin.
But flesh is adaptable, even unwilling flesh. Gradually her body slackened around the relentless intruder. Wetness gathered, reluctant and shameful, easing his passage until the friction transformed into something slicker, hotter, more obscene. Biff felt the change and grinned against her neck. His pace quickened, youthful energy taking over. He began to pound into her with real force, hips ramming forward, the wet slap of skin on skin echoing through the old barn.
Lorraine’s cunt felt swollen, abused, stretched almost beyond bearing—yet beneath the soreness an unwelcome electricity crackled to life. Her nipples had drawn into tight, aching peaks, tingling sharply every time his shirt rasped across them. Each heavy thrust sent jolts of unwanted sensation radiating outward from where they were joined. Her body was betraying her with biological eagerness she could neither control nor forgive.
Then a new thought made desperation claw up her throat. She raised her head, brushing her lips against the stubble of his cheek in a trembling imitation of affection. “Biff,” she whispered, voice light and coaxing, as though she might still steer this nightmare. “You ... you are going to pull out, right?”
He said nothing. Instead he drove into her harder, faster, savoring the wet heat that now welcomed every brutal stroke. The feeling of absolute ownership flooded him—her body spread beneath him, soft flesh quaking and bouncing with every impact of his groin against hers. God, he was enjoying this. The power. The slick grip of her. The way her breath hitched despite herself.
Lorraine’s fear sharpened into panic. “Biff,” she tried again, her anxiety and need of assurance more audible now, yet still gentle, still pitched as if to a reasonable man. “You wouldn’t really come inside me ... would you?”
Still he ignored her. With a low grunt of satisfaction he released her wrists entirely. He rocked back onto his knees, seized her calves, and lifted her legs high, folding her nearly in half. The new angle left her utterly exposed. Exultantly, Biff looked down at the place where they were joined, mesmerized by the sight of his thick, glistening shaft sliding out of her stretched pussy only to slam back inside, her pink inner lips clinging to him on every withdrawal. Her breasts leaped and quivered on her chest with each heavy thrust.
Lorraine was frantic now, adrenaline and unwilling arousal warring inside her. She twisted, trying to wrench away, but his grip on her calves was iron. She clawed at his torso, nails scraping uselessly across his shirt. The obscene visual assaulted her too—the relentless piston of that massive cock disappearing into her body again and again, stretching her wide, claiming her completely. It was demoralizing beyond words.
“Please,” she sobbed, voice breaking. “Biff, I’ll do anything. Please don’t come inside me. You can’t. I’m not— I’m not protected, please—”
Her desperate pleas were the final spark he needed.
Their eyes locked. Biff’s face split into a wide, triumphant grin, teeth flashing in the lantern light. He rammed home in one final, brutish thrust, burying himself to the hilt. His cock swelled and pulsed deep inside her as he began to empty himself.
Thick, hot jets of semen erupted against the entrance to her womb, spurt after powerful spurt flooding her unprotected depths. Biff groaned long and low, hips grinding tight against her, making sure every drop stayed buried as deep as possible. The sensation of his release—wet, insistent, claiming—sent a final wave of horrified realization through Lorraine. She could feel it happening: the rhythmic contractions of his shaft, the warm flood filling her, the unmistakable biological finality of what he was doing.
He stayed there long after the last pulse, still buried to the root, breathing hard, a look of pure masculine satisfaction on his face. Beneath him, Lorraine lay stunned and trembling, legs still held high, her body now marked in the most irreversible way. The barn fell quiet again, save for the hiss of the lanterns and the ragged sound of their breathing.
At length, Biff rose slowly from between Lorraine’s spread thighs, his chest heaving, skin glistening with sweat. He stood over her for a long moment, breathing hard, staring down at the lush, pornographic ruin he had made of her.
