Sheldon moved to the empty car behind them to make the call. They had paid for the last two cars of the train so that strangers wouldn't come wandering through. Pulling out his cell phone once he shut the door behind him.

"Hello, this is Sheldon Cooper. I have a wedding reception booked there in about ten minutes. We're running a bit late, but we'll be there in half an hour." He explained. "I don't care. We've paid to use your services for two hours." Listening to the angry man on the other end he sighed. "Fine. We'll pay you extra for making you wait." With that, he hung up.

As he went to open the door, Penny walked through, shutting it behind her. "Thought since we're stuck on the train for half an hour we could get some alone time." She smirked, moving toward him.

"But, penny, what if someone comes looking for us?" It was a pathetic attempt at a 'no'.

Pinning him against the side, she chuckled. "Sweetie, the bride and the groom both disappear...I think people would know not to come looking for us. Besides, I hit the lock on the door."

A slow smile was beginning to play on his lips. "What about your dress?" That was an actual question, not a way of protesting.

"Oh, I've worked in worse situations. I can face the wall...and lean forward..." As she spoke her hand moved up his leg. "I can tell you get the idea." Penny said against his lips.

Sheldon had lost whatever thought that was in his mind. Kissing her, he pulled her into her body and moved so that she was now against the wall. After a moment, he pulled away, looking her in the eyes.

"Turn around." He said under his breath. She loved that voice. Only she had ever heard it.

With a small nod, she turned around, hiking her dress up as much as she could with his help. His thumbs gripped the sides of her panties as he pulled them down slightly. Once he'd moved them enough to his liking, he stroked her with his middle finger, teasing her. Smirking, he knelt behind her, moving his face forward. He always loved tasting her, hearing her noises. He also loved watching her, but that was something they couldn't accomplish right now. Licking her slowly, he held her lips apart.

"Sheldon, don't tease me!" She wiggled her ass at him.

Not needing to be told twice, he gave her one last lick. Standing up, he undid his pants, letting them move down his thighs a bit. With a hand on each of her hips, he didn't waste any time. Shoving himself into her as hard as he could, they both moaned. Pulling out slowly, he repeated. "Oh Penny." Sheldon let out as he watched his cock move in and out of her. As he fucked her, he watched her ass move. It had always been one of his favorite features of hers.

He knew they needed to get back, but blocked it out. All that mattered was them. "Sheldon, oh God." Her legs were starting to shake slightly, as she tightened around him. Sheldon wasn't far behind. He leaned against her back and kissed her neck. Licking her lips, she chuckled. "You never cease to amaze me." She complemented him as he helped her pull up her panties and straighten out.

"I love you, Penny." He smiled, leading her out of the car as she smoothed her hair back to place. Her face was a light pink, giving away that something happened.

"I love you, too, Sheldon." She beamed.

"Welcome back you two." Leonard teased, smirking. He was finally okay with the idea of them together, and often would pick on Sheldon for it. He'd make little comments about him being a "real boy", and that it was still shocking to him that he had genitals. At first it annoyed Sheldon, until Penny pointed out the humor in it. Now it was just something else between friends. "Did Penny have to talk to the guy, too? I can see how she'd have the upper hand."

Sheldon smiled at his friend and shook his head. "No, had that happened, I'm sure you all would have heard that over the rain. That, and I would have pitied the poor man." Penny raised an eyebrow at him. They all knew she had one hell of a temper.

Once they pulled up to the station, the rain slowed to a drizzle, much to their relief. "Okay, people! The wedding party and the parents will be in one limo. Everyone else will be in the other." Sheldon announced, making sure everyone remembered.

With that, he linked his arm with Penny's and led her out. She didn't get too wet, which she didn't mind either way. After them it was Mary, and Penny's father. They were in a deep discussion over how their children were when they were little. It was amusing them both. After that came Missy, Amy, Bernadette, Leonard, Raj, and Howard. As they pulled away, the others filed into the second limo.

It was a short ride to the reception hall, which Penny spent listening to her father and new mother-in-law. She couldn't help but chuckle. They got along very well, but this also meant that Mary Cooper would be learning about her past. She just hoped that it didn't change how she felt.

They filed out, easily, and as Penny and Sheldon stepped out the second limo pulled up. The newly weds were led to a separate room to wait in until they made their entrance. "Okay, when the time comes for you two to come in, I'll have my assistants open the doors for you. I'll go start the music as people get seated." The dj smiled at them before walking out.

"Well, how do you feel, Mrs. Cooper?" Sheldon asked her as they waited.

"Over the moon, how about you, Mr. Cooper?" She grinned back.

"Lucky." Which said more in one word then he could have said in an entire sentence. He had never believed in luck before.
