It's one thing to travel back in time and find out your dad is as much of a wimp as a teenager as he is in the future. It's another entirely to discover your father peeping on a hot chick while she's changing. Needless to say, Marty McFly couldn't help but be incredibly embarrassed on behalf of his father. Not to mention entirely bemused and annoyed with the man.

Seriously, climbing a tree in order to get a look at a changing woman? What, did they not have porn magazines in Nineteen-Fifty-Five?

Unfortunately, before he can decide what to do with this information, George gets a little too excited and ends up fucking up his own balance on the tree branch he's currently straddling. As the man falls from the branch into the middle of the road with a car oncoming, Marty only has a moment to react.

"Dad!"

He pushes George out of the way, but in the process gets hit by the car himself and knocked flat on his back. The last thing that goes through Marty's concussed mind before darkness takes him is that at least his dad had good taste. The girl he'd been peeping on WAS incredibly hot from what little Marty had seen…

-x-X-x-

Lorraine Baines bites her lower lip as she tends to the young man unconscious in the bed in front of her. Her parents had left in a rush to get medical things to tend to the poor boy's wounds, while her siblings were all downstairs and watching TV. Lorraine, as the eldest of the Baines children, was the one left in charge of watching over the poor car crash victim who'd been hit just outside their house.

She had to admit… he was very handsome. Yes, he was unconscious and that was bad, but from the look of things, the hit he'd taken wasn't TOO bad. There was no blood, for one, at least that she could see. Hm, maybe… maybe she should check though? Slowly, Lorraine's hands move up under his shirt, feeling over his body.

Nothing bad catches her attention, but she does let out a bit of a perverted giggle as she touches him. An unconscious handsome stranger, in her bedroom… oh, what's a young woman such as herself to do? Well, her inspection is FAR from done, that's for sure.

Chewing on her lower lip a bit more, Lorraine begins to fiddle with the boy's pants. The blue jeans he's wearing are a bit of a surprise, some new fashion she hasn't heard about she assumes. But either way, she gets them off of him in short order, taking off his pants… to check for wounds, of course.

His underwear is even odder than his jeans, Lorraine has to admit, but at the same time, she doesn't focus on it for long. Instead, she finds herself focusing on the outline of his d-dick. Not erect in the slightest, he's still impressively sized, long and thick from Lorraine's best estimation. She's never seen a man's penis before, but she's heard of them and Lorraine… Lorraine can't help herself.

Slowly, she pulls down the waistband of his strange underwear, tugging them away from his body to expose his cock to her young eyes. She can't help herself… she just HAS to know what it feels like. A gentle finger poke rapidly turns into a full-blown grip as she cops a feel however, groping his cock with one hand and then the other when she realizes she almost can't even wrap her fingers around his shaft.

She's amazed at how warm it feels, truth be told. The young woman can't help but explore, for all that she's a virgin who's never done anything like this before. It's so warm and… and alive, that she can't hold back from staring at it. Subconsciously, she leans closer and closer, telling herself she just wants to get a closer look.

Soon enough, her lips are just an inch from his dick. Perhaps it's her uneven breathes across the surface of his exposed shaft that finally do it, but whatever it is, that's when he lets out a groan and begins to wake up. Even then, Lorraine can't bring herself to move. Not even when his eyes open and he looks down at her in a confused daze, their gazes meeting for the first time.

There's something about his crystal blue eyes that just… draws her in. Like they already have a connection, or at least that's what it feels like. Of course, no matter what Lorraine is feeling, that doesn't excuse the position he's discovered her in. She opens her mouth and tries to fumble her way through an explanation, only for the young man to cut her off as he tosses his head back and lets out a louder groan.

"Fuuuck your hands feel so good…"

Blushing at the crash language, Lorraine is nevertheless encouraged to keep her hands on his crotch. It feels so… raunchy, but not wrong to be touching him, and before she knows it, she's not only rubbing and stroking this mysterious handsome stranger's dick, but even pressing her face up against his shaft. As she does so, the words finally come to her and Lorraine looks up at the young man with concerned eyes, managing to look both cute and sensual without meaning to as she explains the situation.

"You had a nasty bump, good sir. You got hit by my daddy's car just outside. You should relax. Here. In my room."

She punctuates each of those last sentences with a kiss to his dick, causing the mysterious young man to groan and nod slowly in agreement. With some fidgeting, Lorraine gets his dick out through the hole in his underwear and it finally flops properly onto her face, causing her nose to be pushed up against the underside of his shaft.

For the first time, the adventurous, randy young woman realizes just how WET she already is. She's horny just from smelling him, and before she knows it, she's upon his cock, kissing and sucking at his shaft, leaving sloppy lipstick marks all over his dick and savoring every inch. She doesn't know what she's doing, but she knows it feels good from the way the handsome stranger is continuing to groan and moan his approval.

Finally, he offers a suggestion and Lorraine, still very uncertain of herself but very certain that she wants to do this, happily takes it.

"You could… you c-could put it in your mouth…"

She never would have thought of that on her own. Whoever heard of putting a dick in your mouth, right? It certainly sounds novel, and Lorraine happily follows along with the instruction, ceasing her instinctive and incessant kissing and slurping in order to rear back so her lips are positioned above his bulbous member.

He's a lot harder than when they started at this point, and a lot thicker and bigger for it as well. Lorraine spreads her puffy pouty lips as wide as she possibly can, and it's still nearly impossible for her to wrap them around his cockhead. Nearly… but not quite entirely. As hard as it is to fit him in her mouth, lust and by extension Lorraine herself, ultimately prevails. She takes him past her lips and past her straining jaw and she begins to bob up and down on his member, staring up at the mysterious young man with soulful, lust-filled eyes.

She struggles a bit to take him any deeper than halfway… but her daddy didn't raise no quitter. Or at least, that's what Lorraine tells herself as she forces herself to take more of his cock into her mouth, subsequently causing the tip to slip down the back of her inexperienced young throat. She's soon gagging and gurgling on his member, but Lorraine keeps going, effectively deep-throating the first dick she's ever seen.

"Glughk! Glughk! Glughk!"

She felt like such a champion, managing so much. Sure, drool and saliva were getting everywhere at this point, and tears were pinpricking at the corners of her eyes, but as she looks up at him, heavily lidded and entirely red faced, she's spurred on by the pleasure she sees on his own features. He's enjoying this as much as she'd hoped, so she can't stop now.

Instead she sucks and savors the mysterious handsome stranger's cock like a champ, until finally, he lets out a loud groan.

"S-Shit, I'm cumming!"

Lorraine's eyes widen at that, before she finds herself having to swallow as he empties his baby cream right down her throat. She drank as much as she could, but it was quite a lot, and seeming to recognize that, he pulls back out of her mouth… and ends up covering her face and breasts in his cum instead, the last half of his load squirting all over her front.

Blinking owlishly for a moment, Lorraine can't help but be pleased with herself. The young man looked exhausted, but Lorraine was excited. She'd done that quite well, had she not? Her first time, and she'd handled this handsome stranger with skill and aplomb. Of course, that didn't change the fact that she now needed to clean up.

Giving him a quick smile through the cum coating her features, Lorraine turns away for a moment and begins looking for a handkerchief to clean her face with. Unbeknownst to the young woman, she presents quite the… appealing view as she does so.

-x-X-x-

Marty didn't really know where he was or what was going on. But he had to admit, a blowjob from a beautiful young woman was one incredibly way to wake up. He was still feeling a bit woozy of course, and the back of his head definitely felt like it had a knot developing on it. But whoever this dame was, she was offering an absolutely wonderful distraction.

Even after turning away, she was giving Marty quite the view, her perky rear raised up and kind of shaking from side to side. He didn't know if that was on purpose or not… ah fuck, it had to be, right? Feeling reinvigorated by the view and growing hard all over again, Marty slowly gets up off of the bed he woke up on, swaying his way over to the beauty all but presenting herself to him.

Woozy, but nevertheless VERY certain of what he wants, the young man reaches his goal and grabs her skirt with both hands, flipping it up over her perky derriere to find out what he's working with. The lacy panties she's wearing only turn him on further, causing his cock to jump in disbelief and even further excitement.

In response, the cute brunette jolts and looks over her shoulder at him. As it had before, something about her face strikes him as oddly familiar, but he just can't place it. He has to admit though, the way she blushes as she flicks her gaze between his face and his throbbing cock is super fucking cute. She blushes even more when he gives her a wicked grin and casually rests his dick upon her panty-clad ass.

Not one to mince words or waste time, Marty's next move is to grab those same panties and rip them off, the tearing sound causing the young woman to let out a startled 'eep!' before she manages to cover her mouth and hide her voice. Marty, not even thinking about who else might be in the house with them, knows exactly what he wants… and he's going to have it. The tip of his big fat cock meets her folds, and he grabs her by her hips somewhat roughly.

However, instead of continuing with that roughness, Marty slides forward almost delicately, slowly pressing into her from behind. It's not long before he hits her hymen, but in his current state, Marty doesn't even notice. He just keeps going, and in response the beautiful brunette covers her mouth with her other hand as well, holding back a choked sob as he takes her virginity right then and there.

Groaning as he eventually bottoms out inside of the beautiful young dame, Marty holds position for a moment. She's tighter than his girlfriend Jennifer, he realizes belatedly. His fingers dig into her pert posterior for a moment, before he pulls back only to slowly push back in again. That's the pace he goes at for a little while, not wanting to hurt her.

But wet as she is, the girl definitely wants it harder, something she makes clear to him, once she gets her voice under control.

"M-More… y-you can, nngh, go faster. I want to really f-feel it…"

What a horny young slut. Grinning a little lecherously, Marty lets out a perverted chuckle as he begins to thrust harder. In moments, the brunette he's woken up to has to bury her face in her pillows to contain her moans and squeals. The sound of flesh slapping against flesh fills the air, and Marty does his best not to groan too loudly as he buries himself inside of her tight twat again and again and again.

As the two of them fuck, though Marty is doing most of the fucking while the brunette girl he's plowing is the one being fucked, something in the back of his concussed mind feels a little off to him. But whatever is niggling at his thoughts… it simply can't compare to the tight feeling of this gorgeous babe's cunt. Sure, Jennifer was his girlfriend, and this was a bit of a betrayal, yeah… but hey, he was in the past, right? Jennifer wasn't even born yet, so could it really be said to count?!

In some ways, this new girl can't quite compare. For one, her ass isn't nearly as big as his girlfriend's. But it had enough filling to it that Marty could deliver a nice hard spanking and watch her moan into the pillows in arousal.

SMACK!

"Mmmm~"

SMACK! SMACK! SMACK!

She wanted it hard, right? So he'd give it to her hard until she told him otherwise! Of course, he can tell she's not going to do that. Whoever this gorgeous brunette is, she tightens up spectacularly every time he spanks her, her cunt walls clenching down on his cock. Jennifer certainly didn't like it quite so rough, his girlfriend always making him take it slow thanks to his cock-size, but with this beautiful dame, Marty could really go all out for once.

After a bit longer however, he feels like switching up positions. Jackhammering in and out of this tasty young dame is all well and good, but he is still pretty tired and not at his best. Of course, when he sits back, accidentally slipping out of her, the brunette whimpers and looks back over her shoulder at him in confusion and disappointment.

Giving her the same grin as before, he strokes his cock while at the same time offering it to her.

"Climb on."

Her blush refreshed, the brunette nevertheless does as she's told, scooting back until she's able to slide down his thick fat prick once again. Reaching out with both hands, Marty grabs her by her slim hips and yanks, fully bringing her back onto his cock in a reverse cowgirl position. Heh, did they even have this sex position at this point in history?

Well, even if they did, Marty suspected he was the one introducing it to this lovely young woman. Gripping her by the hips, bouncing her up and down on his cock, Marty can't get enough and seemingly neither can she. She does her best, really she does, but her moans reach HIS ears at least all the same, throaty and wanton as she attempts to muffle them behind her hand.

Unable to help himself, feeling incredibly randy at the moment, Marty begins to reach up and pull her clothing off of her. Her skirt unbuttons and unravels easily enough, followed by her blouse and her bra. He strips her naked and she doesn't fight him for even a second, letting him do it and moaning all the more wantonly when his hands reach around to grab and squeeze at her supple tits.

She's not quite as big in the chest as Jennifer either, his girlfriend more of a woman in some ways than this beautiful brunette. But in other ways, such as her eagerness to please and her exploratory nature, this gorgeous dame is more than enough to top his girlfriend. Is it wrong to compare the two of them when Jennifer hasn't even been born yet and is far in the future? Probably, but Marty isn't really in the right state of mind right now. He's doing a lot of things he probably shouldn't be.

It's not long before he feels his current fuck partner cum on his cock however, and when he does, Marty just grins, getting even more into things. Having played with her titties to his heart's content, he leaves them behind, each of her nipples rock hard from his attention. Sliding his hands under her thighs, Marty scoops up her legs and takes complete control as he begins to REALLY fuck her.

Holding her aloft, he's able to not only bounce her up and down on his dick, but also thrust up into her from below. HE picks the pace from that point on, pounding away at her cunt as the brunette squeals in surprised pleasure and ecstasy, her moans growing louder until she's positively screaming through the hand she's using to cover her mouth.

Her pussy walls clench and harden around his cock all the more, and Marty just groans as he fills her with his thick meaty rod again and again. He can feel himself getting closer to his own release with every time she cums for him. There's no denying it, she's so fucking sexy and incredibly sensitive from the look of things, and Marty just can't get enough of her tight young body.

Still, as he's getting closer and closer, that twinge in the back of his head, that niggling voice that tells him he's making a mistake… its getting louder. It's like some sort of warning. Consciously, Marty doesn't even fully register it's existence. But subconsciously, Marty finally chooses to listen to it.

With a loud groan, he pulls out just as he's about to cum. Rather than creampieing the hot young thing right there on the spot, he instead explodes all over her back and ass. In turn, she flops forward, falling face first onto the bed in a somewhat humiliating pose. Face down, ass up, with her arms splayed on either side of her in clear exhaustion.

He expects to see her move at some point, but as a moment passes, and then another, he realizes she's not getting back up to whine at him for making a mess of her again. He's cum on her face and her tits, and now on her ass and back. But instead of taking him to task for his messiness, he realizes she's passed out on him, the exertion causing the young virgin brunette to fall asleep.

Slumping back in the bed on his own end, Marty lets out an explosive sigh, staring in appreciation at the sight in front of him. As he relaxes however, the full weight of his previous injury starts to hit him… at the same exact time as post-nut clarity as he realizes just what he's done in the passion of this concussed moment.

Taking a second to admire the sexy, naked girl with cum and sweat in equal amounts dripping off of her body, Marty nevertheless realizes that he's absolutely DEAD if anyone sees him now. More than that, this girl was around his age, and this bedroom was the NOT the master bedroom of a house, meaning that she wasn't some hottie coed living alone.

Flushing a little even as his eyes track the hefty trail of cum slowly seeping down the slope of her gorgeous derriere and along her well-fucked pussy, Marty bites his lower lip and then gets up, hastily tucking his junk back into his boxers and getting his jeans back on as he looks this way and that.

In the end, he settles for putting the brunette under the covers up to her neck and wiping her face down with the handkerchief she never got to originally. Afterwards, he stealth runs his way out of the house, sneaking past a bunch of kids watching TV downstairs. Luckily, the little shits had the volume up to maximum, explaining why the hell they didn't hear him and whoever that girl was to them going at it upstairs. Was she their older sister? Their baby sitter?

Marty didn't know and didn't care. As far as he was concerned, what happened in the past stayed in the past, right? Embarrassed but also privately proud of his guilty lay, Marty exits the house and turns his walk into a leisurely stroll, trying his best not to look suspicious, trying to look like he belongs now that he's outside again.

As he starts to make his way back to Doc, however, the young man realizes something. Now that he's outside, he's able to match the house he just came from with the one that he caught his dad peeping into. Which means that the girl he just fucked was the same one his wimp of a father was perving on.

Wincing, Marty shakes his head and rubs a hand through the back of his hair, only to yelp as he feels the knot back there from his contact with the pavement after getting hit by that car. However, it's as he's wincing in pain from this accidental aggravation of his injury that Marty's head turns just enough for his eyes to land on the house's mailbox at the end of their driveway.

"The Baines…"

It takes him a moment to place why that sounds so damn familiar, and when he does, Marty's eyes widen and he whips back around, staring up at the empty window that he knows leads into the bedroom of the girl he just left in her bed after fucking her soundly.

Baines… Baines was his mother's maiden name.

… No way. No fucking way…
