Remember me

When Doc Brown opened his eyes, she was kneeling beside him.

He remembered.

He got shot.

Penny stayed by his side.

And she was crying. Her long honey-amber hair falling on him in soft waves. Her hazel eyes sad, worried.

He blinked, twice. And saw her, holding his hand. The girl gasped.

“Doctor! You’re alive!”

She looked beside herself with happiness. She was crying.

As the Doc showed the letter that saved his life to Marty, the three of them decided to go to his improvised home.


Doc Brown insisted with Marty he needed to talk to Penny. It was urgent.

“What on Earth do you want with my cousin, Doc?Why are you so obsessed with her all of a sudden?”

“You know well why, Marty. Trust me. I need to talk to her.”

“You’re the Doc, Doc…” the boy sighed as he gave in and left, telling them, annoyed.

“Behave.”

In her defense, Penny looked innocently confused.

There she was. His girl.The only one who had ever seen any worth in him.

“I’m gonna have a shower and wash all this grime…” he gave her shoulder a squeeze. A gesture that felt so… intimate. “I’ll be right back to talk to you,” he took her to his makeshift bed in his room, not littered at the moment.

“Sure,” she beamed back at him, blushing.

As he left, Penny frowned.What on Earth? Had her crush finally taken notice of her? Did Marty put on a good word for her?

Penny took deep breaths. At least, she tried to.

An hour later, he came back.

“I’m here, Little Girl,” he surprised her, as she squealed. “Sorry, I didn’t mean to scare you.” he kissed the top of her head. As he sat by her side on the bed, Penny saw he was wearing a silk pajama with the flashy patterns he usually favored.

“Don’t be nervous, Penny,” he grabbed her trembling hands. “I know you just saw me dead… But we’ve been together many times before. Even before the Time Machine. You were my student… And that’s how I decided to quit something I hated to invent things that didn’t work.”

That was when she realized there was something wrong. They had never been together.Not like this! Even though she wanted to, he always ignored her!

Not anymore, it seemed.

And ‘a student?’ Penny was trying to find a publisher for her first book. She never went to university! And to study physics? Hardly.

“It’s so strange,” he gently traced the neckline of her t-shirt with his finger. “You look so much… younger.

“You mean I used to look like an old lady to you before?”

He shook his head, and Penny knew she was about to be kissed.

He couldn’t notice that she didn’t know how to kiss! This would ruin her life right now!

But it was almost like a choreography. He gently kissed her lips, played with her tongue, as the girl moaned, like she was in heaven. He was flattered. It was almost like Penny was seeing him for the first time. As he touched her breasts through the tee and started playing with her hard nipples, Penny gasped, throwing her head back.

“Oh, my god. Oh my god! This is by far the best day of my life!”

He laughed, pulling her tee over her head.

Penny was flushing with shame, but he didn’t notice it.

“Oh, I missed those delicate sweet things,” he caressed her breasts thoroughly. Penny gasped, her legs trembling as her body shook and she barely muffled a yell with a grunt.

“Baby girl! Are you all right? You are so…intense today.”

“I– I’m sorry!” she flushed violently.

“It’s all right, Little Girl! This is actually great!” he nibbled one of her nipples delicately, as she gasped, holding on to the sheets desperately. Then he licked and sucked each hardened peak, as the girl couldn’t help but cry out with abandon.

“Here, baby girl,” he stood up a little destabilized himself. “I need to play with you a little. Stand up.”

She did it, almost losing her balance. As she stood up, he pulled her skirt down and slid down her panties.

Penny gasped, shaken.

“It’s all right, baby girl… I just need to look at you.”

Penny didn’t dare say anything. She just nodded, breathing fast.

Humiliated, she could feel her arousal trickling down her legs.

But he looked mesmerized, touching her pussy.

It was too much for the girl. Her legs shook uncontrollably, she gasped and nearly fell. But he held her.

“Baby! What am I doing? This is amaz–”

“It’s just that I missed you so much,” she said as an excuse, mortified.

“Me too, baby girl. Lie down. Let me taste you.”

At this point, Penny would do anything that godly man demanded.

But when he started tasting her… She forgot she shouldn’t ruin everything. She forgot why she shouldn’t. Penny shrieked, begged, held onto his white hair like a lifeline. She even forgot where she was and who she was. When she came, more than once, she pushed his head away, crying for him to stop.

“Too much, Little Girl?” he asked, licking his lips.

“I love you,” she said, stupidly in tears.

“I love you too,” he said, finally getting rid of his clothes, and about to do something Penny had been afraid of.

And he probably noticed.

“It’s all right, Little Girl,” he pulled her up, again. “You know him very well,” he placed her hand on his shaft, as Penny stared at it, baffled.

“It’s so…so big!” she exclaimed, astonished.

“Yeah, you said that the first time too,” he chuckled. “This is all too flattering to an old man like me, Penny. How can you still look the same? It’s like I’m relieving every special moment with you all over again.”

“You’d be surprised,” she snickered.

“Here, Little Girl… Play with it,” he closed her hand around it and worked it up and down, up and down as he hissed. Penny bit her lower lip to control herself this time. Getting near the girl without any warning, he pushed into her and Penny groaned in complaint, pushing him slightly.

“I’m sorry, Little Girl. Let’s lie down. Oh, I missed the feeling of your body. I miss you all the time,” he held her, pushing into the girl gently.

Penny gasped loudly as he entered her, trying to stop traitor tears from falling.

“Penny,” he asked, worriedly, “Am I hurting you?”

"No, I– I’m just… Happy.”

It wasn’t a lie, but the Doc knew better.

“Penny. Why am I hurting you?”

“Don’t do this to me. Please. Don’t destroy the best day of my life!”

At this point, he already knew what was wrong.

The same time. An alternate reality.

How? A glitch in the machine? A rift in time?

“No wonder I didn’t know Marty even had a cousin! You’ll have to fill me in on everything,” he said, nuzzling her face. “I hope I don’t go to jail, as I’m already going to hell!”

“No. I’m,” she panted. “Twenty!”

Penny gasped, as he increased pace.

“Is that good, Little Girl?”

“Yes, yes! Perfect! Oh, dear god! Oh! God!” Penny shouted, a little too loudly and he chuckled, sheepishly. As the Doc moved, the girl almost fused herself to him, begging, moaning.

“Oh, my sweet little girl!”

Penny gasped, shaking violently, eyes going to the back of her head, as he shook, entwining his hand with hers, not being able to repress a cry himself.

They held each other in shock, trembling like an electric current ran through their bodies.

“Great Scott!” he exclaimed, barely able to breathe. “Who are you?’

“I’m the same Penny,” she giggled. “Aren’t I? You are the only one who seem to have changed. You used to ignore me. You treated me like I was an annoying brat,” he could hear the hurt in her voice.

“Yeah, and now I know why,” he held her closer, laughing.

“It wasn’t like that. You probably really hated me.”

“I’m sure I tried to. I hear you describing me when I’m trying to avoid a problem.”

“You figure I was a problem, then?” she laid on his chest, staring at him.

“No.You’re still one,” he pulled the girl to him, kissing her. “Oh, Marty will never forgive me!

“Marty will never know,” she played with his hair, as he held her closer.
