This parody includes teenagers, who are all over eighteen. ***** (...Alan Silvestri music...) "Mom?...That you?" Marty McFly awoke into darkness and the sound of pouring rain outside, his head still throbbing. "There, now. Just relax" came his mother Lorraine's soothing voice beside the bed. Marty felt a cool washcloth on his forehead. "You've been asleep for almost nine hours now" said Lorraine. "I had a horrible nightmare" groaned Marty. "I dreamed I went...back in time. It was terrible." "Well, you're safe and sound now. Back in good old 1955." Marty's eyes snapped open. "1955?!" he yelled, just as the bedside lamp clicked on. Bolting upright, he quickly realized he wasn't in his own bed, or even his own room. And he hadn't been talking to his mother - not exactly. She was young, and thin, and beautiful, with luscious brown hair in an old-fashioned coiffe and big doe eyes that smoldered at him. She looked a lot like Lea Thompson, one of Marty's favorite actresses ever since seeing her bikini scenes from "Jaws 3-D." It had never occurred to him before this moment how much his mom resembled a older Lea Thompson. Or rather, how much this Lea Thompson lookalike resembled his mom when she was younger. Hey, wait a minute! "You're my mo-...you're my mo-..." "My name is Lorraine" said the beautiful girl, glancing down bashfully and then up at him again with those big brown eyes. "Lorraine Baines." As she spoke, she took off her sweater, revealing the slender arms of a teenager - unlike the flabby pterodactyl wings Marty was used to seeing on his - on his - no, it couldn't be! "Yeah! But you're ho-..." Marty croaked. "You're so ho-..." He couldn't say it. "You're so...thin!" he blurted instead. "Just relax Calvin, you've got a big bruise on your head" she said in the caring, motherly tone of voice that Marty had grown up with. It was bizarre hearing it come out of this gorgeous young girl. Panicking, Marty touched his forehead and tried to roll out of bed. The blanket he had slept under fell to one side, revealing his bare legs and Calvin Klein underwear. "Where are my pants?!" "Over there" answered young Lorraine nervously, pointing across the room. "On my hope chest. I've never seen purple underwear before, Calvin" she smirked, staring shamelessly at her future son's package. "'Calvin,' why - why do you keep calling me Calvin?" stammered Marty, trying to distract himself from the thickening sexual tension in the air. "Well that is your name, isn't it?" asked Lorraine. "Calvin Klein? It's written all over your underwear..." Lorraine sat up from the adjacent bed and sat beside Marty, who flinched but did not attempt to cover himself up. "Oh, I guess they call you Cal" Lorraine purred sexily, stroking the top of Marty's thigh. "No, actually" gulped Marty, his head spinning. "People call me Marty." "Oh. Pleased to meet you, Calvin" his teenage mother cooed into his ear, bringing her head closer to his. Lorraine's dainty little hand trailed up Marty's thigh and over his bulge. Marty was becoming lost in his mom's enchanting brown eyes as his cock stiffened. She gazed back at him with animal hunger. "My parents aren't home yet" she whispered. "And I feel so awful about what happened, I can't believe my father knocked you down with his car." Marty was starting to remember what had happened earlier, and how he'd been knocked unconscious. But more importantly, he was starting to gather what was happening this very second. He HAD gone back to 1955. And this WAS his own mother, back when she was a mere 18 years old. "I feel like I ought to help you feel better, Calvin." Lorraine Baines fished Marty's hardening cock out of his Calvin Klein underwear and began to squeeze it, stroking her hand up and down from the tip to the base, until his dickhead was leaking precum and lubricating her expert handjob. Holy shit, thought Marty. Mom really knows what she's doing! He watched her handiwork, then glanced up into the not-so-innocent schoolgirl's brown eyes again, which were brimming with unknowingly incestuous desire. "Call me Marty." "Okay" said Lorraine. "Marty." With that, she leaned in closer and stuck her tongue into Marty's ear as her hand circled around his lubricated rod. This was getting serious, thought Marty. Deciding to take charge of the situation, he stood up from the bed and faced his mom. She was breathing heavily now as she began to stand up with him, but he set his hands on her shoulders, stopping her. "You stay down there, Lorraine." "Oh! Yes, Marty" she responded eagerly, more turned on than she'd EVER been in her young life. Oh man, this is going to be great, thought Marty. Finally mom's going to do what I tell her, instead of bossing me around. If I'm stuck 30 years in the past, I might as well use it to my advantage! "Pull down my underwear" he commanded. Her heart nearly beating out of her chest, Lorraine Baines complied submissively. She dropped to her knees on the hardwood floor of her room and pulled her future son's briefs down to his ankles, leaving his unsheathed boner aimed directly at her pretty face like a loaded gun. "Oh my gosh, Marty" blushed his teenage mother-to-be. "I've never - I mean, I've never seen one this big before. It's...colossal!" "Heh, yeah, well" mumbled Marty. "Whoa, hey!" Without warning, he felt Lorraine's nails digging into his ass cheeks, as she gripped them tightly and shoved her face deep into his crotch. Marty felt his dick melting into his mom's soft wet mouth. Lorraine Baines took a whiff of the handsome stranger's sweaty pubes as the tip of his cock slipped past her uvula. She gyrated her neck, stirring up her own throat with his hard meat. "This is heavy" said Marty to himself, wiping a trickle of sweat from his brow. He looked down at Lorraine, whose chin hadn't left his balls. She stared back up at him and winked. Marty felt a finger creeping deeper into his ass crack. "Oh, no you don't" he warned, grabbing his mom's hands from behind him and pulling them away. Damn, just how wild WAS his mom, back when she was his age? He'd never had any idea. But now it was time to find out. "I'm gonna start fucking your mouth, Lorraine. Get ready" he warned. Lorraine nodded her head in acknowledgement, or as much as she could with a mouthful of Marty. He stepped out of the Calvin Kleins that lay around on ankles on the floor, widened his legs, and let go of his mother's arms to grab two handfuls of hair on the sides of her head. With increasing abandon, Marty violated Lorraine's throat, face-fucking the horny bobby-soxer. For her part, Lorraine didn't offer the slightest bit of resistance as she unwittingly let her future child have his way with her skull. "GLUG! GLACK! GLUCK! GLUCK! GLUCK!" gurgled Lorraine. "Oh shit, Lorraine. Oh, fuck..." muttered Marty, running his fingers through her thick brown curls. "Here it comes!" Several big doses of Marty's spunk (a few days' worth, as his girlfriend Jennifer Parker hadn't been an option recently) shot down Lorraine's throat and into her belly. Only when he was completely drained did he release his fistfuls of her hair, allowing her head to slide off his manhood. "Golly, Marty" she gasped. "That certainly - that certainly was interesting. I've never - never had a boy make love to me like that before." Marty watched Lorraine pat down her hair as well as she could, then emit a small burp from the load she'd just sucked down. His load. Watching his slutty young mother compose herself after giving him the best head he'd ever experienced was slightly surreal. What had just happened BARELY seemed real at all. But what had, in the last 24 hours? No sense holding back now, he figured. Time to go for broke. "Okay, now. Stand up, Lorraine" he ordered. Lorraine did what she was told, rising up on slightly wobbly legs, still a bit dizzy from administering her killer blowjob. She blinked her eyes into focus and saw Marty, or Calvin, or whatever his name was, studying her intently, with a look that indicated he wasn't done with her yet. "Ooohh, Marty" murmured Lorraine, grabbing for his junk once again to delicately fondle his balls with one hand and use the other to play with his shaft. Within moments, her hands had him stiffening up to full erectness. Partly it was Marty's youthful virility, but more than that, he was going out of his mind as this impossibly perverted dream come true. Lorraine simply took the compliment swelling in her loving hands the only way she could have. "Looks like your little - your 'mister happy' wants to have some more fun, Marty" she giggled. Every time he heard his mom call him by name, Marty felt more blood pumping through his veins. He was mentally undressing his mom, suddenly realizing that she'd had her clothes on this entire time. Now, more than anything, he wanted to see his young mom's body. He HAD to. "Let's see what you've got under there, Lorraine" he grunted. "Turn around." Lorraine happily spun around, presenting her backside to Marty. Her dress didn't have any zipper or buttons, so he kneeled down to pull up the one-piece garment over his mom's head. Christ, he thought, people used to dress like the Amish around here. It feels like I'm undressing my grandmother. As soon as the ankle-length dress lifted up past Lorraine's calves and thighs, Marty discovered a new surprise - black nylon stockings held up by garter straps. Continuing to raise the dress further over Lorraine's waist, Marty's eyes bugged out at the sheer black panties those garter strips connected to. The underwear was ridiculously large by modern standards - covering not only Lorraine's bikini area but wrapping around her hips and waistline, up to the belly button. But that ass! His teenage mom's supple ass was incredible. Unlike the aged Lorraine Baines-McFly of 1985, Lorraine Baines' butt circa 1955 was one you could bounce a quarter off. Marty paused the unfurling just to appreciate it. "Fuck, mom!" "What was that, Marty?" asked Lorraine. "Uh, I said fuck, mom - momma - red hot momma. You're one red-hot momma" he offered lamely. "Well, thank you, Marty" she smiled. "Do you like my special underwear? I've never worn it before. I was saving it for someone...special." Lorraine lifted her arms up and Marty pulled the rest of her dress up over her head, casting it aside. She faced Marty and what she faced him with was stunning. Wearing a lacy black brassiere to match her panties and stockings, she looked like a girl from one of those black and white photos Marty had once found in his grandfather's garage. They showed two housewives straight out of "The Honeymooners" on someone's couch, pretending to spank each other. But this was the real thing - in living color, and his unwitting mother on top of everything else. As he gave her the once-over, Lorraine squirmed in giddy pride at being ogled. She pouted her lips, placed a hand on her hip, jutted her ass out to the side and with her other hand, bunched her hair up atop her head and pushed out her bosom. "What do you think, Marty? I'll bet I kind of look like Bettie Page, don't I?" Marty didn't know or care who she was talking about. His eyes were glued to her chest - round, full b-cups stuffed into that black bra, not sagging down to her ribcage like the mother he knew back in the future. These puppies were in the bloom of youth and just begging to be squeezed. So he did. Marty groped his mom's boobs through the sexy brassiere and she moaned with pleasure, closing her eyes and titling her head back. "Oh wow, Marty. That - that feels so good. You - you certainly know how to handle a girl!" "Okay, Lorraine" he said, nearly drooling while his fingers kneaded into her soft tits. "I can't take it anymore. I've gotta fuck you." "Oh yes" groaned Lorraine, her breasts shivering in his hands. "Yes, Marty. Take me. I want you to - I want you to be my first man." Marty's hands stopped their mauling. "You're a virgin?!" he exclaimed. "After all of that?!" "Well, gee" said Lorraine self-consciously, looking at the floor. "I may have sat in a few parked cars with boys before, but I'm not just some cheap hussy." She looked back at Marty and took a half-step forward, pressing her lithe little body against his. "But I want you, Marty" she continued. "I know we've only just met, and it sounds crazy, but watching you asleep in my room for hours and hours, I started to feel some kind of - I don't know, kinship with you! Like we were always meant to be together someday...like it's my destiny to have you inside me." "You can say that again" chuckled Marty, his hardness returning for round two. "Hey, are you on the pill?" "The...pill?" asked Lorraine quizzically. "I take my vitamins, if that's what you mean." "Forget it" he said, moving behind her. Marty clasped Lorraine's shoulders and motioned her onto the bed that was still warm from his long rest. Her whole body was trembling with anticipation. Marty climbed on top of her and violently ripped her panties apart, tearing the fabric open and uncovering her hairy bush. "Wow, girls really didn't care about keeping themselves trimmed back then" thought Marty as the pungent scent of his teenage mom's arousal wafted through the air. "Hey, this underwear cost ten dollars!" she whined. Marty placed his hand atop Lorraine's muff, feeling the heat rising from underneath her patch of brown fur. His forefingers slipped down into the velvet folds of her pussy, which was tight as a vice. As he fingered her throbbing cunt, Lorraine's hips gyrated from side to side and her legs began to thrash. "Oh my goodness!" she panted. "Marty, you're driving me crazy! Please, put it in me! Put it in me NOW!!" Marty withdrew his hand from Lorraine's soaked pussy and held it under his nose, savoring the smell of her lust on his fingertips. He looked down at Lorraine, eyes burning with intensity. "Lorraine, before I fuck you...before I take your virginity, there's something I have to tell you." Lorraine swallowed nervously, mentally preparing for the worst. This boy was a sailor, after all. "Sure, Marty. What is it?" "Lorraine...I'm from the future. I came here in a time machine, from the year nineteen eighty-five." Lorraine stared blankly at the stranger in her bedroom who was poised over her, naked from the waist down, with his tubesteak ready to plunge through the entrance of her womanhood. Her expression betrayed nothing as Marty continued with his absurd confession. "Lorraine...in the year nineteen eighty-five, you have a son. Me. I'M your son. From the future." There was a silence that seemed to last an eternity. Finally, the corners of her mouth curled up into a confused smile. "Holy Toledo, Marty! You've got quite the imagination." "I'm not kidding, Lorraine" he rebutted. "I'm totally serious. I just need you to know that...before we do what we're about to do." "Okay, sure, Marty. Whatever you say" said Lorraine. "You're my son. From the future." She reached forward and grabbed his engorged member, guiding it to the opening between her legs. Her eyes narrowed and her mischievous little smile grew wider. "So what are you waiting for? Fuck me, future-boy. Stick that big fat cock in your mom, stick it in me when I'm just a bad little horny teenager. I want to feel my future son's prick in me. I want my son to make me a woman. Do it to your naughty young mom, young man. Show me what kind of bad boy I'm going to raise. Take your own mom's virginity, you time-travelling motherfucker!" That was all Marty needed to hear. He thrust his hips forward and sank his cock into Lorraine. He watched her face grimace with the initial pain of lost chastity and then slowly morph into open-mouthed ecstasy as he nailed her tight and juicy little pussy, over and over. "Oh! OH!! Oh, MARTY!!" she wailed as his balls slapped her ass, picking up speed. Marty leaned back, grabbing Lorraine's ankles and pulling her legs further apart as he enjoyed the view: his teenage mother in pinup girl lingerie, writhing like a slut while impaled on the end of his dick as he continued to pound away. Even Jennifer never felt so good. Lorraine opened her eyes and gazed up at him. "It - it feels terrific, Marty" she moaned. "How do you - how do you like fucking your mom? Back when she - I mean, when I'm only a teenager??" "It feels fucking great, mom!" Marty answered back, feeling her cunt spasm all over his dick while the sounds of skin slapping against skin echoed throughout the room. "Ooh yes, Marty!" she cried. "Keep calling me 'mom'! That's so naughty!!" Marty frowned slightly. She clearly hadn't believed him. She was simply open-minded - or crazy - enough to roll with what must've seemed like his weirdly convoluted sex fantasy. Some part of him wanted her to know what was really happening. But how was he going to convince her, or anyone else, of how he'd arrived here in 1955? Fuck it, thought Marty. "Take my fucking cock, Lorraine. Take your own son's cock!!" he growled, as he banged his own mother. Suddenly, their fourth-dimensional passion was interrupted by a voice calling from downstairs. "LORRAAAINE? Are you up there?" "Oh my god, it's my mother!" screamed Lorraine. "Get off me! We've got to get dressed! QUICK!! Put your pants back on!!" ——————————————————— Later, at the end of the movie, the rockin' sounds of Huey Lewis and The News woke up Marty to a whole new reality. Home at last, he'd soon discovered that his monkeying around with the space-time continuum had transformed his brother Dave into an up-and-coming yuppie, and his sister Linda from a 3 into a solid 5. Not only that, his put-upon loser dad had become athletic, confident and a published author. Thank God, thought Marty, that he'd been able to convince young Lorraine the only way he could achieve orgasm was to be cuckolded by a lesser man - a young man named George McFly - thus ensuring his own future existence. Shortly afterwards, he'd been handed a set of car keys by his dad's former bully, Biff Tannen, now just a sniveling, lowly auto-detailer. Marty raised the garage door and found waiting for him the sweetest ride ever designed by man: a black 1985 Toyota Hilux 4x4. He walked up to the truck, ran his hand along its sleek hood and shook his head in disbelief at all his good fortune. "How about a ride, mister?" he heard a young girl's voice ask. Marty couldn't believe his eyes. It looked like that girl from "The Karate Kid," Elisabeth Shue! But she was wearing his girlfriend Jennifer's denim vest...could it be? "Hey, you're - you're - are you...?" "Yeah Marty, it's me!" laughed the girl. "Don't you recognize your own girlfriend? Are you okay?" Holy crap, thought Marty. I should change history more often. "Jennifer! Oh, I guess you just...seem a little different today" he sighed, walking over and holding her tenderly. "Marty..." said Jennifer, a little concerned by her boyfriend's odd behavior, "You're acting like you've never even seen me before! Is everything all right?" Marty glanced back at the front door to his house, where his dad was proudly showing off the first edition copies of his debut novel "A Match Made In Space" to his brother and sister. "Oh, yeah" said Marty to the new, hotter Jennifer. "Everything is great." They leaned in to kiss, when another female voice spoke up from nearby. "Hey, you two! Aren't we getting a little ahead of ourselves?" Jennifer and Marty looked over to see a sexy older woman in high heels, click-clacking her way up the driveway towards them. For a split second, Marty thought that young Lorraine had somehow followed him forward in time! Back to the Future M/S "Oh, hey Mrs. McFly!" chirped Jennifer. Then it hit him, of course. Yes, it was his mom, Lorraine. But aside from a couple extra pounds and some laugh lines around the eyes, she was looking just as good as she had in 1955...maybe even better! His formerly frumpy present-day mother now had an amazing body, and judging by her clothes, she loved to show it off: standing atop her pumps, Lorraine's toned legs were clad only in purple leg warmers. Her tight buns were in micro-shorts that left little to the imagination. Her midriff was bare, displaying a smooth flat tummy below a cut-off t-shirt that read "PARTY GIRL." From the sweatbands around her wrists and across her forehead, Marty guessed she'd just come from the aerobics class downtown, the one full of babes he'd usually wave at on his way to school. Lorraine McFly beamed at her son as she strode over to him and his girlfriend. Marty was already in a state of shock from the physical transformation of the two closest women to him in his life, leaving him ill-prepared when Lorraine brazenly mashed her tits against his chest and nibbled at his earlobe. "Maaart-eeeee" she cooed, instantly taking him back to that fateful night 30 years ago. "I know we've been planning this big night up at the lake for two weeks, but don't you think you can wait another few hours?" She planted a few un-motherly kisses along his neck. "At least wait until I've taken a shower" she giggled. "Muh-mom!" Marty stammered. "Are you - I mean, are we - are you coming with us?" Lorraine and Jennifer both laughed. "Nooooo, Marty" said Lorraine sarcastically, placing a hand on her hip, giving Marty a flashback to her lingerie pinup posing back in 1955. "I've ONLY been trying to convince your father that I'm spending the weekend at my brother's...JUST so you and Jennifer can have all the fun." "Oh, Mrs. McFly" snickered Jennifer. "Like you'd EVER let me get away with not sharing Marty!" Marty felt Jennifer's hand on his blue jeans, feeling up his junk. Then her hand moved past him to brush her fingers along Lorraine's firm abdomen. "I don't know HOW I ever get him away from you these days" teased Jennifer. "Your Jazzercise classes are really paying off. Look at you, I'm SOOO jealous!" "Oh, I sure like her, Marty. Such a sweet girl" grinned Lorraine, leaning in front of Marty towards Jennifer. The two women parted their lips, closed their eyes, and kissed with open mouths, swirling their tongues just inches away from Marty's face. Despite the blood diverting from one head to another, Marty still had presence of mind to think how this was all starting to make sense. That night with his mom must have planted the seeds in her head to look at her future son a little differently...and the night he'd spent making sure his dad George knocked her up had no doubt set her off on a more sexually adventurous path in life. Breaking their kiss, the two ladies each threw an arm around Marty, hanging on him as their other free hands roamed up and down his chest, pawing at him like two groupies. "Won't this be fun, Marty?" asked Lorraine. "Just the three of us, camping by the lake with some beers, some marshmallows..." "...And some Marty sandwiches!" Jennifer piped in. They tittered with laughter, and Marty couldn't help but smile. He could definitely learn to like this new timeline. "I think I could actually go for a Marty hotdog...riiiiight now" intoned Lorraine, her voice getting husky as she dropped her hand down into his pants and softly pinched the top of his dickhead. "I always get REALLY fucking horny after a workout." "Ooohh, Mrs. McFly" said Jennifer. "Let's close the garage door and give Marty a little preview of what we're going to DO to him this weekend." Mouth agape, Marty felt himself being silently led back inside the garage as his mom pulled the door shut, leaving the trio shrouded in darkness with only a few rays of afternoon sunlight for illumination. Lorraine joined Jennifer in front of Marty, who leaned back against the truck. Simultaneously they dropped to their knees, and Jennifer rushed to unzip his fly. Marty shook his suspenders off the tops of his shoulders. His mom yanked his jeans down to his ankles, and stared for a moment at the bulge inside his briefs, recalling some distant far-off memory. She snapped out of it and finished pulling the purple Calvin Kleins down around his ankles, freeing his warm hard dick into the cool, dry air of the garage. Marty felt himself enveloped by the warm wetness of Jennifer's mouth as it glided up and down his shaft. Lorraine's mouth joined in below, lovingly sucking her son's balls. He felt four hands stroking his naked thighs as the two cock-hungry sluts devoured his crotch. Jennifer slid her head off of Marty's dick and tossed her denim vest aside, to unbutton her blouse. Lorraine took Jennifer's place, moving up from Marty's nuts up to the underside of his dick, slurping it like a runny ice cream cone. As Jennifer undid the last button, her blouse fell to the floor. She cupped her tits and pushed them upwards against Marty's cock. Lorraine paused from sucking it to kiss Jennifer's pert little nipples, then pull her own tight t-shirt off in one fluid motion. She was wearing a red sports bra underneath, which was also quickly gone, allowing her set of middle-aged but nonetheless fantastic mommy-boobs to bounce back and forth. Lorraine thrust her heavy udders alongside Jennifer's as they squashed their jugs into Marty, smothering his dick and balls in their pillowy titflesh, loving the feeling of his cock growing harder and harder as it rolled between their racks. Soon neither of them could stand it anymore. Gripping his thighs, Lorraine and Jennifer moved in to better worship Marty's cock. "Wanna take Marty's dick this time, Mrs. McFly? I could work his balls" suggested Jennifer. "Oh, that's sweet of you, Jennifer. But I think there's enough Marty for both of us. He's such a big boy" she giggled. So they dove in on him, Lorraine going for the base while Jennifer attacked the tip. Marty looked down at his mom and girlfriend, who both looked up at him with their mouths full of his cock, and - as if they'd somehow timed it - winked at him in unison. After the events of this past week, it was all a little too much to take with any kind of stoicism. Marty began to cum. "Uh-oh, there he goes!" squealed Jennifer. Only the first spurt was wasted on the cement floor. Lorraine took her son's ejaculating member and aimed it at Jennifer, sending a streak of hot cum across her face and into her hair. Marty watched as his girlfriend opened her mouth wide and caught the next burst, quickly gulping it down. As Jennifer swallowed, Lorraine aimed Marty's next blast at Jennifer, coating her perky teenage tits with a sticky load. Then she placed her son's organ on her own chest, splooging a couple of lovely pearl necklaces around her clavicle. Jacking her son's dick, Lorraine leaned in and closed her eyes as she wrung a final wad of Marty's thick seed square in the middle of her face. Marty's knees buckled as he leaned against the truck. He looked back and forth from his mother to his girlfriend, who were now licking his cum off each other's faces and playfully smearing it into each other's tits, making them glisten in the setting afternoon sunlight. "Oh man, mom. Oh man, Jennifer" he finally declared. "That sun's going down fast. Maybe we ought to get going. We can stop at the drugstore for some condoms on the way to the lake." "Condoms?" chuckled Jennifer as Lorraine started to lick her cum-glazed tits clean. "Where we're going, we won't - ahh! - we won't need...condoms." THE END
