'We've gone out every night for the past week Amy and he still hasn't kissed me.' Penny sighed as she spoke to her friend over the phone.

'Penny it took him a good three years before he even kissed me, you just have to give him time.'

'He knows what I am like though, surely the thought should have crossed his mind. We always come so close to it on our dates and then bam he backs out last minute.' Penny sighed.

'Give him time Penny, and if not just use Carpe Diem as your guide'

'Carpe what now?'

'Carpe Diem: It's Latin for seize the day. If you want to kiss him so bad… why don't you go and do it yourself?'

'Ok, maybe I will, thanks Ames.' Penny smiled and hung up the phone. Slipping on a jacket, she left her apartment. Her destination: Sheldon Cooper's office, Caltech University. Her goal: to kiss her man.

'Cooper! You were supposed to be in my office twenty minutes ago!' Kripke yelled, storming into Sheldon's office.

'That's odd because I had no intention of being in your office 20 minutes ago,' Sheldon said, not bothering to look up from his paperwork.

'That's not good enough Cooper. If this continues I will have to weport you to Gabelhawser. He assigned us to work together and you awen't doing your job by sitting on your ass all day when you are supposed to be in my office showing me your wesearch!' Kripke yelled.

'Fine, I shall fax it over as soon as I can Kripke, now leave me alone. I need to work.' Sheldon said in a bored tone of voice. As Kripke left, Leonard entered, 'Shut up.'

'I didn't say anything.' Leonard said, looking confused.

'You were thinking, it's annoying and extremely distracting.' Sheldon sighed. 'What do you want?'

'It's vintage game night tonight. Since we haven't played for the last two weeks, I was wondering which game you wanted me to pick up from the store?'

'Leonard, I am extremely busy and I won't be playing tonight anyway, so pick up whatever you want.' Sheldon sighed, getting up and writing an equation on the board.

'What is with you lately, you seem to be changing. You aren't… Sheldon anymore.' Leonard said quizzically and with that he left.

10 minutes later the door banged open.

'Oh for God's sake!' Sheldon cried turning around to see Penny standing in his doorway and immediately his expression softened and a smile appeared on his face, 'Penny? What are you doing here?' he asked and she shut the door behind her, locking it.

'I thought I'd come and see the world's most brilliant physicist,' Penny smiled.

'Penny, I'm working…'

'Well, perhaps you can tell me what you're working on?' Penny asked, sitting down in Sheldon's seat. Sheldon looked at her and shrugged to himself. He saw no harm in it.

'Alright, well what I'm working on here is how to…' Penny tuned out his explanations on string theory.

'Ok, I have a question.' She quipped and Sheldon looked at her.

'Fire away,' Sheldon said, turning to face her fully.

'Um, were you planning on kissing me, um ever?' Penny asked and Sheldon looked at her initially with shock before swallowing.

'Er, that's definitely a er a valid question and the answer to that question is er yes,' Sheldon said nervously, writing YES on the white board as he spoke, 'Yes I was.' A smile erupted on Penny's face and she felt her heart race as Sheldon made his way closer to her. Penny puckered up slightly but found herself once again being faced with Sheldon's voice, 'But you see, I want it to be perfect. I want to give you a phenomenal kiss that you would remember because well it's you.'

'Oh Sheldon that's so sweet,' Penny gasped, smiling at him.

'See the problem is, the longer I wait, the more phenomenal the kiss I give you has to be.'

'Then don't wait.' Penny said huskily, however Sheldon didn't notice as he was too busy getting himself in one of his OCD frenzies.

'And now, it's gotten to a stage where I feel like I have to sweep everything off say, this desk and throw you down on it and I'm afraid I don't' think I'm a well sweeping sort of fella.' Sheldon said. Penny stood up and walked over to him.

'You know you overthink things way too much,' she said, wrapping her arms around his neck. Leaning in, she then gently kissed him on the lips. It felt nice kissing a tall guy again. Sheldon, to her surprise, melted into the kiss and pulled her closer, placing a hand on her waist and deepening the kiss.

'You know, for someone who hasn't kissed a lot of people, you sure are good.'

'Thank you.' Sheldon grinned and Penny laughed.

'Oh Sheldon,' She giggled, moving forward to kiss him again.

'Penny, as much as I enjoy your presence, I really do have a lot of work to do,' Sheldon smiled, releasing her from his grip.

'I know,' Penny sighed, 'I'll see you tonight.' She said softly, pressing another quick kiss on his lips.

'See you tonight Penny.' Sheldon smiled, sitting back at his laptop and immersing himself in work so much so that he barely noticed Penny leaving.

A good couple of hours had passed before Leonard re entered Sheldon's office with Howard and Raj. The sight before them truly boggled their minds. Sheldon was… happy. He was smiling and singing to himself as he worked and it kind of freaked them out.

'What a day it has been,

What a rare mood I'm in,

Why it's almost like being in love,

There's a smile on my face,

For the whole human race,

Why it's almost like being in love.' Sheldon sang whilst bobbing his head and writing down equations on his board.

'Ahem.' Leonard cleared his throat and Sheldon spun around.

'Oh hello, can I help you?' he asked and Leonard raised an eyebrow.

'You realise you were singing out loud don't you?' Howard said and Sheldon blinked at his colleagues.

'No I wasn't.'

'Er, yes you were.' Raj interjected and Sheldon cocked his head to the side.

'Are you sure, that seems very unlike me.'

'Sheldon, all three of us saw you!' Leonard cried, 'What's got you so happy?'

'I don't know,' Sheldon lied. He knew the reason was Penny but he didn't want to reveal their relationship just yet, especially since it was still early days, 'I'm just feeling extremely happy today.'

'Come on, it's time to go home.'

'But I'm not finished,' Sheldon frowned.

'Well you'll have to get the bus home then Sheldon, cause we're off,' Leonard said.

'Very well,' Sheldon grumbled.

'I'll see you back at the apartment then.' Leonard sighed, and the three of them left.

'Just think, you'll soon have that Nobel Prize Sheldon, just think Nobel Prize, Nobel Prize.' Sheldon began to chant that over and over again.

Leonard, Howard and Raj all were laughing in their seats, a beer in their hand and Dungeons and Dragons in the middle of the table when suddenly the door banged open to reveal an angry Sheldon.

'Do you know what, the bell should be treated no differently than every other mechanical failure on the bus!' Sheldon yelled, practically throwing his keys into the bowl.

'Oh dear Lord, Sheldon's on a rampage,' Wolowitz murmured and Leonard and Raj chuckled.

'I fail to see what is so funny! The illumination of the bus passenger sign gives the passenger the confidence to remain in their seat until the bus becomes stationary. If it doesn't work, you get incidents like today's when a largely built woman fell on top of me because she needed to walk towards the front of the bus to make sure it stopped at her stop!' Sheldon ranted before storming to his bedroom to change.

'I don't know about you but that has made my day,' Raj laughed.

'I'm sure he deserved it.' Leonard added, 'Sheldon bugs everyone, it was karma getting back at him.'

The three of them laughed again before being interrupted by a knock on the door and Penny poking her head around the door.

'Sheldon…' She started to call out before she saw who was in the room. Leonard jumped out his seat.

'Penny!' he cried, running towards the door and opening it fully. 'Come in!'

'I think I'll er come back later. See you guys. Leonard.' She began to turn around to leave but Leonard caught her hand.

'Penny, Sheldon just came home and has gone to get changed. Please, just sit down; he'll be out in a minute.' Leonard begged and Penny let out a pained sigh.

'OK, whatever.' She breathed, sitting down at the breakfast bar.

'So um, how are you?' Leonard asked.

'I'm as can be.' Penny said. The atmosphere was so tense it could be cut with a knife and an awkward silence fell across the room.

'So er Raj, I need to show you that thing outside,' Howard said, pulling Raj out of the apartment. When they were alone, Leonard let out a deep breath.

'Penny, I need to speak with you.'

'Yeah, well I don't want to talk to you. I think I'm just gonna go.' Penny stood up and Leonard grabbed her arm again, 'Let go of me Leonard.'

'Penny, please.'

'Just bugger off and leave me alone!' She yelled, wrenching her arm away from Leonard and going back to her own place, slamming the door behind her. 2 minutes later, Sheldon emerged.

'What was that?'

'Penny was just here.'

'She was?' Sheldon couldn't help but let a small but dreamy smile cross his face as he thought of her.

'Yes, she was looking for you.' Leonard said, his voice laced with suspicion.

'Oh, well I'd best get over there.' Sheldon said, almost running out of the apartment. As he left, Wolowitz and Koothrapali re-entered.

'Wow Sheldon whizzed out of there quickly.' Howard laughed.

'You don't think something's going on between them do you?' Leonard asked, fearing what answers his friends would give.

'Hello, Sheldon would never be able to score someone like Penny.'

'Whist you make a valid point Howard, we mustn't forget that Sheldon was Penny's rock after you cheated on her Leonard. Plus he has been out every night for the past week, as has she. You said yourself that Sheldon told you that she had moved on.' Raj hypothesised, sitting down.

Leonard and Howard looked at each other, 'Sheldon wouldn't do that to me though would he?' Leonard said biting his lip, 'He knows I still love Penny.'

'Dude, I thought you and my sister were back together?' Raj asked.

'We are… I think, but I will always love Penny. We shared something special and it's not easily forgotten.' Leonard sighed. Suddenly his phone rang, the caller ID being Priya's. 'Hello.'

'Hi Leonard, um… we need to talk.' Priya said, sounding nervous.

'Those are words no one wants to hear… are you OK babe, you sound scared.' Leonard frowned and Raj looked at his friend in worry.

'Leonard, promise you won't freak out and no one must know about this yet, especially Rajesh,' Priya said slowly and Leonard felt his stomach drop. He had a dreaded idea of what was coming and he prayed that it wasn't what he was thinking. He almost ran to his room so he was alone and sat down on his bed.

'I promise.'

'Leonard, I'm pregnant.'

Leonard bowed his head, rubbing his eyes. What was he going to do now!

'How did this happen?' He said quietly, 'I thought we used protection.'

'We did, but not on the night Penny caught us. I took the test this morning and it said I am one to two weeks pregnant, so the timing is accurate,' Priya sighed over the phone.

'What shall we do?'

'Well, it goes against my morals and beliefs to get rid of it, so I will have the baby.'

'Ok, so I guess we're having a baby… yaaaaayy.' Leonard said defeatedly, this was the last thing he wanted. He wasn't ready for a baby! He imagined having children with Penny, not Priya.

'Yes we are, gosh Leonard, we're going to be parents. I'm so happy.' Priya laughed, not picking up on Leonard's tone of voice. Breathing in deeply, Leonard put on a phony smile.

'Me too Priya, me too.' He said before hanging up. He needed a drink, and he needed it now.

Oooooooooh, didn't think I would put a pregnancy in this story, but I figured karma should come and bite leonard in the butt. Also, finally wrote in Sheldon and Penny's first kiss… Sorry I kept you waiting for 14 chapters but the best things come to those who wait haha. Next chapter will be up soon, hope you enjoyed this one.
