Back to the Future Tg Mommy McFly

In Hill Valley, California on 1986 Marty McFly sat inside with his girlfriend Jennifer Parker playfully kissing each other as they talked about plans after high school. Marty wanted to get his music career up and running and after Doc had disappeared somewhere in time the past six months had been quiet. 

"So, babe" Marty coyly said. "Any plans now that high school's over and you have your boyfriend long term?"

"Marty as long as I'm with you I'm happy. The rest will fall into-"

Jennifer was cut off as a DeLorean appeared on the street with a trail of tire tracks right behind it. Out of the machine stepped Doc Brown with the usual bewilderment in his eyes.

"Great Scott, Marty! There's been a disturbance in the space time continuum" he said yelling at Marty through the window. By the look on his face there was no time for catching up. Marty felt this too when he started to fade away. Seeing through his hand Marty sensed something was horribly wrong. Looking at the picture frame of his parents at prom (which he had previously gone back to fix) was now just his father standing alone. All the pictures of his mother were empty. He had to fix this before he disappeared. Running outside he hopped in the time machine with Doc in the driver seat sending them off up the street before taking off from this timeline.

"What the heck happened Doc?"

"It's Biff."

"Did he realize you had a time machine?"

"No, no it wasn't on purpose. I, I did something idiotic Marty."

"Did you bang your head on the sink again?" He had, but that wasn't the cause of the problem.

"I-"

"Yeah"

"I..."

"Just spit it out already before I fade completely."

"Oh don't worry about that, you're stabilized while your in the Delorean. Time is still in flux here." Doc Brown sighed before admitting, "It was the car Marty. A complete mess! I needed to get it cleaned so I had Biff come over and, well, he accidentally started it up. It was still set to the mid 50's."

The car suddenly stopped, appearing back into the 50's as they surveyed the wreckage of another car before them.

"That's my dad's car! Does that mean-" He quickly got out of the smoking vehicle and saw his young father in the car, unconscious, but fine.

"Biff happened to appear right where their car was and slammed into it as your parents were canoodling in the front seat." Marty then saw his mom on the street ahead, crumpled on the asphalt. He remembered his dad saying he always wore his seat belt no matter what he was doing in the car. It seemed that wasn't an exaggeration.

The storm clouds above were still booming as he went to see his mom's body. Right before he could check her pulse or even prod her, a bolt of lightning came down from the sky, attracted to the residual energy of his time traveled atoms. Both him and his mom were shocked together as her atoms burst into an electric cloud that flew into Marty, knocking him unconscious as the world seemed to glow blue before fading to black.

"Wake up sleepyhead, you'll be late for morning classes." Marty woke up in a frilly bed, confused to find himself in women's pajamas. They looked like something his mom would have worn when she was his a- the accident! He bolted upright and looked for anything with a date on it. He saw a paper in the hands of the woman standing over him and briefly spotted the date, Friday November 4.

"How did a week pass backwards?" The oddly familiar woman who had woken him up didn't seem that amused. 

"There is no time for foolishness Lorraine now get dressed young lady before breakfast gets cold"

"Young lady?" Marty rubbed his head confused. "Old broad needs her...eyes checked". Looking into a mirror he was weirded out to see himself in obviously woman's clothes. "Jennifer would never let me live this down is she saw me. Did that woman call me by my mom's name? Was that Grandma?" Marty paced the room looking for any trace of male clothing.

"No dice. Looks like I'll have to go with this for now" Digging through her underwear drawer he found a set of plain looking under wear. Taking no time at all he through on the first dress he could find as it seemed his mother's wardrobe didn't consist of pants whatsoever. Looking back at the mirror he shuddered. Heading downstairs he hoped to sneak out the front but the older woman noticed him and immediately spoke up.

"Lorraine, you sit down right this instance. I spent all morning cooking breakfast for you and your siblings". Red faced Marty turned around and sat down in the empty seat with the rest of his mom's immediate family. Slowly eating breakfast Marty couldn't stop thinking about the last thing he had remembered with his mom. Luckily he had been sent further back in time somehow without the help of the DeLorean. Still the fact that everyone seemed to see him as his younger mother was worrysome. Maybe Doc knew what was happening. He could imagine his lecture now.

"Something, something of epic proportions" Marty said to himself quietly as his mom's mom shot him a glance. Looking back to his plate he suddenly thought of something he hoped wasn't true. What if I show up in this timeline where I went to the past to fix the past? Doc's always going on about never interacting with your past self. If everyone thinks I'm Mom I wonder what else could happen?"

He started to dig into his breakfast, a nice stack of pancakes, but slowed won when he was glared at. He started to eat how he thought a girl was supposed to eat in the 50's getting easier as a strange kind of muscle memory set in. His nails grew a little longer, losing any signs of chewing as a small layer of clear gloss accented the daintiness of his slimming fingers. By the time he was halfway done with the plate, his palms were soft and wrists compressed as his small precise movements became second nature to him.

Even though he was starved when he started digging in, he soon felt like he couldn't take another bite. His stomach rumbled a little as it pulled in slightly, losing its flab as it turned more toned. With a gingerly pat down of his mouth, Marty got up and headed out the door, or at least he tried to, but his grandma came running out with a school satchel. Her scolding was cut short only because she knew he had to "put some pep in his step" and get to school. It was annoying at first, running in a tight pair of women's shoes. They weren't even sneakers, but the preppy kind with a buckle on the front and made with some hard material dyed pink that clicked every time the heels hit the ground.

Every step he took felt less uncomfortable, the footwear not as cramped as his feet gradually shrank. By the time he made it to school, his feet were now four sizes smaller with cute toes and slim heels, his soles arched now to become a perfect fit for the shoes. Wait, why was he going to school? Especially dressed as a girl. Even though his grandma saw him as his mom, things wouldn't end well if he looked like a boy in drag. Especially not in this decade. He turned to move away, but was startled as he heard someone shout at him.

"Where do you think you are going young miss? Hmm?" A rather unpleasant teacher with thick, horn-rimmed glasses stomped over to Marty, grabbing him by the ear as he dragged him inside the Hill Valley High School, his pinched ear getting a pierced. Well at least he wasn't about to be attacked by a mob for his clothes.

"Trying to skip class Lorraine? Highly irregular for a student such as yourself. You are not one of those morons like Biff and his brigade of buffoons." He finally let go of Marty's ear before opening the door to his class and gesturing Marty to sit down for class.

"Ouch. Lay off will you" he said, his ear being more sensitive than usual. His voice almost had a slight tremble as if he was about to cry. Shaking it off he sat down in the empty seat and waited for the lesson to start. The mean teacher went to the board and started to write. Trying to pay attention and just blend in Marty heard a couple of guys in front of him snickering and looking back. One even pretended to drop his pen and looked directly at Marty. Following his eyeline Marty instantly went beat red crossing his legs to cover his exposed panties. As he did this his calves thinned down while his thighs thickened. Marty wasn't angry for some reason more ashamed as if he had done something out of character. Hearing the gasp the teacher turned to him and shouted.

"Lorraine! Since you seem so keen to answer perhaps you know the answer". Marty stood there dumbfounded his pencil going towards his mouth. As it rested there his lips plumped becoming pillowy and glossy. Suddenly something clicked: "The answer is 37" he blurted out in a confident tone despite sucking a math and having no time at all to skim through the question.

"That's...right". He said dumbfounded. "Nerd" whispered another student as part of the room snickered. Rather than feeling insulted by the title he felt kind of proud as if he had hope to where that title as a facade to hide his true nature. He was craving a smoke...but he never smoked a day in his life. This oral fixation was apparent when he realized he was sucking on his pencil as the lesson went on and had zoned out. Twirling a dainty finger through his hair it grew longer cascading into a beautiful 50's haircut a woman would have. Reaching into the bag his grandma gave was a brush. Pulling it out he brushed the hair as if it was a usual way to pass the time. The bell ringing it snapped him out of his trance as he shot out of his chair with everyone else.

He decided he'd split after lunch, surprised how much time had already passed. A quick look in his bag showed a brown paper bag which he pulled out as he entered the lunchroom, unsure where to sit. 

"Over Here Lory!" A group of giggling girls in pastel colors waved at him, clearly pantomiming for him to take the empty seat. Lost beneath the general roar of the lunchroom was the sound of his hips popping, his walk turning into more of a saunter as his hips widened, pushing his knees together in their long skirt.

Wondering what he would say without making them suspicious, he sat down, surprisingly finding the gossip at the table interesting. Actually, it felt like it was all coming back to him as he joined the girls in giggling. One of them, Beth said a voice in the back of his mind grabbed him by the chin, softening the feature as she looked at his face.

"Looks like Lory forgot her makeup today girls." They all laughed while Marty blushed, that feeling of shame creeping up again as his cheekbones snapped under his furious blushing.

"Aww don't worry, we're only pulling your leg Lory. Here I'll help." Beth took out a bulky case filled with different accessories and makeup and started to work on his face.

Marty's face was putty in her hands as she added some simple blush and foundation, softening his rough features with each touch up. His nose wriggled a little, shrinking down to be cute as a button. Seeing Beth uncap a tube of lipstick, Marty felt his nicotine craving coming back as he puckered up, his lips a sensual red as Beth sheathed the lipstick back. With a final little check, Marty's eyebrows plucked themselves to wispy arches while his eyes slanted to finish off his adorable face. Beth smiled at him and said, "Much better. Can't have you going around like that a week before the dance."

"Thanks, girls" Marty said sheepishly but with a coy smile as if it actually felt good to be pretty. 

"So who are you taking to prom, Lorry" asked one of the other girls.

"Oh gee. I'm just waiting for the right person...er fella to ask" Marty tried to side step the question. 

"Speaking of which" Beth started, "do you have a dress ready for that perfect night". 

This made Marty's stomach drop as if he had forgotten something really important. "Um not exactly-"

"Girl we are skipping next period and taking you to get ready for Mr Right"

Marty thought of how strict his grandma was and if he was getting in way too deep. Usually if he was to skip class it was to jam sesh with his band not play dress-up. But something was oddly compelling about the thought. A stern look with his hand on his sides, his waist sucking in adding more curve to his figure. 

"Well I would hate to be unprepared" the girls all giggled and headed for the dress shop, Marty forgetting to eat his lunch.

After a few minutes of shushing themselves and hiding behind doors as teachers passed through the hallways, they successfully snuck out. Now that they were outside and not under the watchful eyes of teachers or parents, Marty could finally scavenge through his satchel, pulling out the pack of Marlboros he had hidden in his pencil case. Wait, when did he hide- ah forget it. Flicking a dainty thumb against his hot pink lighter he lit up the end and took a long drag, coughing a little as his Adam's Apple burnt up in the smoke.

"I feel much better," he said in a high soprano.

"Do you have any hooch in there?"

"Nope, just smokes. Maybe we could get some when we find me a dress." The walk over was fairly uneventful, although his legs grew a few inches longer, swaying with his hips, one foot in front of the next. The bell over the door tinkled as they entered the dress shop. Raising an eyebrow at the girls coming in during school hours, the owner just let them be. Money was money after all. Marty tried on a few dresses, all of them not quite sitting right on his body, but none of them really wowed him.

"Try this one on Lory" His friends had found a beautiful pink dress with a darker fringe on top. When he took a closer look, he saw it was actually polka dotted, for some reason it seemed to resonate with him, almost like it was meant to be. He went into the changing room and tried it on.

"It's perfect," he whispered as his shoulders snapped in, reducing his frame as his arms filled with womanly fat. He could imagine the fun he'd have in this dress and the fun he'd have taking it off. Moaning at the thought, his stomach fully sucked in, making the dress fit snugly on his slim waist. Another moan escaped his lips as his ass pushed out, turning him on as it swelled to a sexy heart shape. He took it off and put his normal clothes back on before telling the cashier, "I'll take it!"

Paying for the dress with some money she had for some reason remembered taking from mom...er grandma's purse when she wasn't looking Marty and the girls headed back on the street. The excitement he was feeling off the other girls giddiness was contagious as he took it out of the box holding it up against his body. 

"Hey, Lorraine" heard Marty. Recognizing the voice it made him shudder but even more so than he normally would. In fact he was feeling oddly more nauseous than annoyed as if he had been changing while someone had walked in uninvited. 

"What do you want, Biff?" he said coming off much sweeter than intended. Turning around he flashed the meathead a stern but unintentionally cute look.

"What do we have here?" he said attempting to grab the dress from Marty's hands. 

"Why don't you take a long walk off a short pier" he said coldly hoping the buffoon would get the hint.

"Say the dance is coming up and what do you say going with the hottest fella in school?"

"I'm busy that night". He obviously wasn't letting up and Marty had to think of something.

"Doing what?" he almost interrogated her.

"Washing my hair!" What a stupid line Marty thought instantly regretting his choice of words. 

Walking quicker away from Biff with his mother's friends in tow. His rear swaying side to side with his hips as his spine gained a natural curve adding more emphasis to the feminine fat currently on his body and that soon to come.

Why did he always push his buttons? Every time he saw Biff it left a bad taste in his mouth. Maybe it was his annoying cockiness. He wasn't the worst looker, but all he had to do was open his mouth and anything he had going for him just disappeared. 

"Don't let him bother you like that Lory. He's just a jealous doofus that couldn't get a date to the dance unless he forced them. You have plenty of other admirers anyway." Marty blushed a little, teenage hormones clouding up his brain even more as his preferences changed. He didn't like talking about his love life with his friends!

"OOH! What about George? He's kind of a geek, but I think he's sweet. Hell he'll probably do whatever you want at the dance." That name set off a few things in Marty that made him feel a little flushed. It was weird enough feeling attracted to his mom, but now he was having some strangely erotic images of his da- friend from school. But he didn't swing tha- well he was cute. 

"Thanks for the advice, but I need some alone time to cool off. Thanks for getting me out of class, even if there was a little nuisance here today." His friends made mock booing sounds before leaving Marty alone to walk the streets. He lit up another cigarette and looked at his watch.

"GEEZE LOUISE!" That dress shopping had really eaten away at his day; it was already four! No wonder Biff and his goons were out harassing people. His stomach rumbled a little, reminding him that he hadn't eaten since breakfast. Didn't he have to go see someone or something? Some kind of doctor, but he just couldn't think of the name anymore. If he wanted to visit anyone, he needed remember it soon. He only had a few hours until he had to get home, maybe a good burger would jog his memory. Crunching his lit cigarette under the heel of his shoes, he walked into the nearest diner he could see.

Stepping into the diner the ambiance of 50's oldies to Marty now seemed much more fresh but familiar at the same time. The jukebox was blaring some Elvis Presley which made Marty think of that...hunk of a man, gyrating his hips...jeepers it was enough to make a girl melt. Biting his lips he craved something creamy. Taking a seat at a booth which he instinctually thought as his 'regular' booth the owner walked over.

"Hi Lorraine!" The cheerful man came over. "What can I get for you?"

"My usual, please" he smiled.

"One strawberry shake and a cheeseburger with fries coming right up!"

Oh the thought of that made him salivate. Marty was usually a chocolate kind of guy like his dad but he had a different type of pallet it seemed. Thinking back to George he tried to imagine him at prom. He was such a square but then again some people thought that about her- er him. Maybe with a little hooch he could make a bad boy out of him. A bad boy like...James Dean.

As the owner brought over a shake Marty absent mindedly brought the straw to his lips twirling the straw around his tongue almost moaning in his seat as the tang of sweet strawberries hit his tastebuds. His food arrived shortly after as he grabbed a fry and dipped it in his shake making sure to get some whipped cream too. Taking a bite butterflies filled his stomach. Mmm...the two best tastes: salty and sweet. Feeling a warm shiver run up his spine he felt an odd sensation of his nipples being harder than usual. And more...tender. His chest was becoming a new pleasure region and the bite he had just taken of the juicy burger felt even more satisfying with his smaller appetite.

It was fun just rolling the meat around on his tongue, savoring the flavor as he swallowed. GASP. The burger didn't just go down his throat, it pushed out, small, wonderful bumps forming under his nipples, his whole body feeling turned on. The first strums of Love Me Tender started to play as he took his next bite, almost choking as her body made her moan quietly. God this burger was just a riot, but she had to control herself, she-her didn't want to seem easy to the other restaurant goers, but the next big bite of burger was even better, his chest now up to an a-cup as his blouse rubbed him in the right ways.

He chased down his burger with another gulp of milkshake. "AH" It felt like heaven as his caboose gained a little more cushioning. 

"I am leaving a damn fine tip before I go." Good thing he got a booth, he must have looked pretty lewd as he slid his feet along the ground, twitching in ecstasy, his breasts now gaining a jiggle as they swelled to B's. The last bits of burger were scarfed down as she mouthed a silent yes, giving a moan despite her best intentions as her breasts finished growing, each bounce sending another wave of pleasure coursing through his-her body. The milkshake was next to go as he slowly rose from the seat, his ass now filling out to a cute, but not so petite derriere. It all felt so good he felt like he was about to- oh, ohhh, OH.

He jammed a manicured hand over his mouth before he screamed, just barely stopping himself from blowing his load in the diner. He wasn't sure what had gotten into him, but he knew he couldn't let it happen here. He also realized he forgot to put on a bra earlier, his nipples clearly outlined from his top. He felt mortified, glad to see that it was starting to get dark out. Rummaging through his satchel, he found a sweater his gran-mom always packed in case it got cold. Slipping it on, he was glad to see his nipples were barely visible, but he still felt ready to burst. Quickly leaving his money on the table next to his cleared plate, Marty hustled out of the diner and headed home to take care of some... personal matters in the comfort of his bedroom.

Getting home as fast as he could the added bounce of his rear and breasts was rather distracting. He even noticed guys were staring as they passed by. Oddly though he didn't mind. A little attention was flattering and he was quite a catch after all. In fact to be desired was a turn on now. Arriving home he told Gran- mom that she had some homework to do before supper and to not disturb her. Not thinking twice of it she told her daughter dinner would be ready in a few hours after her father got off work. Heading up to his room Marty closed the door softly and looked through a small variety of records to put on. "Mr Sandman" seemed appropriate. Taking the vinyl out of the case she set the needle on the record and laid on her bed. That build up sensation inside him yearning to be released had not gone away but he was no longer in the edge. He'd have to work his way back to it. Peeling off the sweater his vision while looking down was focused on those perky nipples, tenting through the material of his dress. Poking one a quick jolt went through his body both exciting and overwhelming. This time he would be gentle slowly bringing his hands over his fleshy globes. 

"I shouldn't be doing this...it feels so strange...but so right" he thought as he let out a feminine coo. Trying to fight the urge to give them the attention they craved he tried to rationalize why this was wrong. These were his mom's...size. Of course they were. All the Baines gals had womanly curves like his. He was thankful he had inherited such a beautiful set of gams. He took pride in the girl's change room for gym class seeing the jealous looks the other girls shot him. 

Lifting off his dress and draping it on a chair beside her bed and in front a vanity mirror (being careful not to get it wrinkled) Marty closed his eyes and began to play with his nipples. Each circle with his delicate nails sent waves of pleasure through him. This felt amazing. Well as amazing as usual except for the heat building in his crotch hidden beneath the panties. He needed release and the right pleasurable thoughts to get his engine going.

Speaking of engines going, there was a bright flash of light in the distance as a car going 88 mph burst from the time stream, but that didn't matter quite yet. Marty was too busy fondling himself at the moment trying to get off as he pulled his panties down and started to rub one off. He tried thinking of someone from school, but that didn't help so he went to movies.

James Stewart was too wholesome, Brando too aggressive. He needed someone adventurous, someone unlike the other people in this little town. Someone like James Dean.

"MMM" He moaned as his cock began to shrink, each lewd thought sending another spasm as "he" became less and less accurate. He imagined herself as Judy in Rebel and moaned into his pillow as his balls shot up into his body with two bursts of ecstasy. He wanted someone to save him from, well Biff could be a good replacement for Buzz in that movie and she groaned happily as she imagined him getting punched out, her cock almost halfway in. 

It kept slipping in as he got to the scene in the mansion, Dean leaning in to kiss her. He was pushing down on it near the end, twisting his nipples slightly as he finally heard a wet POP and screamed in ecstasy, her pleasure muffled by her pillow as her cock turned into a sopping wet vagina, her new clit forming as she experienced her first female orgasm.

"YES YES" She spasmed as the throes of her first orgasm died down, leaving her feeling satisfied and exhausted in her bed. Maybe she'd just tell mom that she was too tired and needed some beauty slee-CRASH!

The newly complete young woman poked her head by the window seeing her father's car on the street stopped in front of a young man who was unconscious on the ground. "Oh daddy. Not again". She had remembered her father hitting someone before recently luckily he just walked it off. However this fella was on a train to Snoozeville. Hearing her father say they'd have to bring him inside she quickly darted from the window slipping her panties back on. This time remembering to put a bra on for her impromptu guest she put her dress back on. Making sure her make-up was touched up she hurried downstairs.

Halfway down the steps she nearly ran into her mother and father bringing the recently hit guy up to her room. "Lorraine" her father said in his voice of authority "I don't want this kid suing us up the wazoo. You're going to take care of him and when he comes to your mother has agreed to have him eat with us. Make sure he feels welcome". She turned around and saw her siblings looked concerned so she gave them a nervous smile before heading up to her room. Her mother examined his head and didn't see any bruises. "I think you lucked out again, dear. You probably just knocked the wind right out of him". Her father grumbled before heading for the door. "Lorraine remember I'll have to work overtime for the next five years if this goes sideways" he said. "Gee, pop no pressure" she said, her mother passing her to leave.

Looking back at the guy there was something awfully familiar about him. She got closer to take a better look. He sure was a handsome fellow. Cute even. Gears started to turn in her brain. He looks just like...just like...me! Shit he's me and I'm-. Running over to the mirror the former Marty looked at his reflection this time seeing a younger version of his mother looking back at him. It was as if he had awakened from a dream. Eating breakfast with his folks, skipping class, buying dresses, touching his...oh god! It was his mom but it was him...er her own body. Pacing back to his former body he sat beside it. He had to wake himself up and stop himself from doing whatever he did to end up in this mess. Touching his doubles face something odd happened. The conflicting memories of Marty and his mother fought for dominance. After all, as far as this timeline was concerned she was never Marty McFly. Her brain rebooting almost like a computer (which wouldn't be invented for a while as far as she was concerned) as she opened her eyes. She was Lorraine Baines. A horny eighteen year old woman with a rather tall glass of water of a man lying on her bed. She had no idea who he was but she'd like to know him more...intimately. Peeking down his pants she noticed he was wearing purple underwear. What a hip cat she thought. She'd never seen that color before. They even had his name on them: "Calvin Klien". She ran the name over in her head: Mrs Lorraine Klien. She liked the sound of it.

"I appreciate the offer" 'Calvin' started, "it's just that-"

"Oh I see you're awake, young man. You look well and chipper" Lorraine's mom said. Lorraine rolled her eyes knowing her mom was doing just as well of a charade to cover Pop's responsibility. "Let's head downstairs and join the rest of the family".

Lorraine was still a little full from that late lunch earlier but she could pretend to eat if it meant spending more time with Calvin. During dinner Pa and her siblings Milton, Sally, Toby, and baby Joey all seemed transfixed on the new moving picture box called a television that Pa and every father had seemed to put in their house. All she could pay attention to was Calvin. He made a funny joke about having already seen a brand new episode of a show her brother was watching. She could tell he had a way with her family. Her mother and father seemed to approve of him. Her ears especially perked up when they realized how late it was and told Calvin he should spend the night. 

"Calvin could stay the night in my room" Lorraine said innocently to her parents but under the table was sliding her hand up Calvin's thigh so he'd know what she wanted. Butterflies in her stomach nothing turned her on quite like appearing innocent to some like her parents but being a wild gal without them knowing.

Calvin seemed flustered leaving abruptly. He must have been nervous or playing hard to get. Lorraine was happy she had tended to herself before Calvin showed up or spending the night without him would be unbearable. Still daydreaming about him and only barely hearing her father say he'd disown her if she had a kid like that she headed back up to her room with Calvin on her mind and by the time she woke up the next day, it would be as if nothing had ever changed.
