'Behold, the relationship agreement,' Sheldon said, placing down his newly written document in front of Penny, 'This is a binding covenant in its 45 pages that numerates, iterates and codifies the rights and responsibilities of Sheldon Lee Cooper, henceforth known as "The Boyfriend" and Penny Olivia Miller, henceforth known as "The Girlfriend".'

'That's the same speech you gave to Amy isn't,' Penny said, a small smile reaching her lips.

'No. Amy's relationship agreement was 31 pages, yours is 45. So I fail to see how that makes it the same speech.'

'Hey! Why is mine 45?!'

'Your relationship agreement includes coitus, Amy's didn't include coitus. It also includes the parameters that will define how we can improve our relationship in contrast to our first attempt.'

'You have a section on sex?' Penny said, raising her eyebrows.

'Yes, every aspect of our relationship must be covered Penny. We have to work hard at our relationship now and with this as a guideline, things should run more smoothly. Now, why don't you skim through, whilst I get my notary stamp?'

'Really Sheldon? A section on sex!'

'Penny, just be grateful I'm not also giving you a roommate agreement too! You agreed to sign this agreement as part of the terms of us resuming our relationship.'

'Alright, let's have a look at this thing,' Penny said with a feeling of dread. She opened up the relationship agreement and peered through it, starting at the sex section which had been labelled "Coital Regulations". 'We can only have sex on the weekends! Sheldon, you can't schedule sex, because that takes the fun and spontaneity out of it! Besides, you haven't seemed to mind until now when we have sex.'

'Penny, I know you're a big old 5 but…'

'It seems to me if we're going to have a relationship agreement, it cannot be one sided. I don't agree with the sex part. I have needs too… I like a healthy sex life and I like it frequently… not controlled and regulated.' Penny said, looking Sheldon straight into the eye and he sighed.

'Fine, we shall take away the coital relations section but I must insist that coitus still takes place on Friday, Saturday and Sunday.'

'We can have it every day of the week if you like.' Penny winked and Sheldon blushed, clearing his throat.

'Anyway, please make your way through the relationship agreement and tell me of anything else you wish to change.' He said and together they spent the next hour and a half rewriting the relationship agreement, to which (to Penny's delight) removed nearly 98% of the original document. Picking up the pen, she signed the newly printed relationship agreement. Sheldon followed suit and then stamped the document, 'Thank you for signing this Penny, it means a lot to me that you did.' Sheldon said and Penny smiled at him.

'It's alright, I'm just glad we're together again.' She gently leaned forward and placed a small kiss on his lips, 'I wonder how Priya, Leonard and Raj are doing,' she sighed and Sheldon shrugged, 'I prayed for the first time in a LONG time when Naiya was born. I prayed that she would live and grow up to be happy and healthy but obviously it went unheard.'

'I thought you didn't believe in God,' Sheldon frowned and Penny sighed.

'I don't, I just thought that maybe… if he was real, he would you know help out. It was a spur of the moment thing I guess.'

'Well it was the thought that counted,' Sheldon said, pulling her in for a hug. They both jumped when the phone rang and Penny answered it.

'Hello? Sure, I'll just pass you over,' Penny said before handing the phone to Sheldon, 'it's Gablehauser for you.'

'Hello?'

'Hello Dr Cooper, Gablehauser here.'

'Good afternoon,' Sheldon said.

'I have great news for you Cooper. The Royal Swedish Academy of Sciences called today… you've done it. You've won the Nobel Prize.' Sheldon was speechless. He had done it. He had finally gotten a Nobel Prize at the age of 34! 'Cooper? Are you there?'

'I… I'm here sir… wow it's an honour… I'm speechless.'

'Well there's something I never thought I'd hear,' Gablehauser chuckled, 'In recognition of your accomplishments, we want to make you Head of the Physics and Science departments of Caltech University with a raise of $40,000 which would make your annual salary at $110,000. And as you well know, you will get a $1.1 million dollars with your Nobel Prize, so congratulations Dr Cooper; you are a credit to the University.'

'Th-th-thank you, I won't let you down I promise, thank you Sir.'

'See you tomorrow Cooper, goodbye.'

'Bye! And thank you again Dr Gablehauser!'

Sheldon turned around to Penny and lifted her up, twirling her around before crushing her lips in an extremely passionate kiss, leaving her gasping for air.

'Woah! What was that for,' she gasped, still breathless from the kiss.

'I've done it! I've won the Nobel Prize.'

'Oh my God! Sheldon I'm so proud of you! Well done!' Penny hugged him, beaming with pride.

'I can't believe it! This is even better than the time we first engaged in coitus! And they've also given me a promotion that comes with a $40,000 raise!'

'Oh honey, that's fantastic.' Penny laughed, deciding not to comment on the fact he had just belittled their first sexual encounter.

'And I was thinking that, after I get the million dollars that comes with my Nobel Prize, we could move and get a nice house somewhere.'

'That sounds amazing,' Penny grinned, 'I guess you'll have to find a new goal to achieve now too.'

'I've already got one in mind and I've had it in mind for quite some time now,' Sheldon smiled sneakily.

'Oh really, do tell.' Penny laughed, staring deep into his eyes lovingly.

'A life with you,' he said softly, taking her hands in his.

'Really?' She whispered, 'You've thought about that?'

'Yep,' Sheldon smiled, 'we're gonna have two kids, a boy and a girl.'

Penny smiled; somehow knowing that Sheldon had planned his version of their future together was completely different to the way that Jason had done it. Sheldon made it sound sweet and romantic, like had put serious thought into it. Also, it also helped that it was coming from someone she was head over heels in love with. It made her get a warm feeling in her stomach and she found herself craving to know more, 'What else do you think about?'

'Well, stuff like places where we could live. Maybe out in the suburbs where our kids can roam around in a nice large back garden and learn to ride their bikes, we could have a cat that had a bell on its collar and we'll call him Zazzles because our cat will be very zazzy… I shouldn't really have given the first Zazzles away but we can have a Zazzles mark 2. We could hear him come through the little kitty door… oh and we'll have an apartment over the garage where I could set up my lab so I can start researching into cloning and time travel.'

Penny found a large smile cross her face, 'You know what? I want everything you just said. I want that life together but you know when you said cat… you meant dog right?'

'No, definitely a cat but I suppose we could get a dog as well,' Sheldon frowned and Penny laughed before leaning up and kissing him.

'You promise we'll have that someday?'

'I promise it will happen,' Sheldon kissed her nose and broke their embrace; 'I suppose you will want to find a suitable dress for when you accompany to claim my Nobel Prize.'

'You're taking me with you?'

'Of course, you're the only person I'd want to accompany me to Sweden. I think this might be the best day of my life,' Sheldon grinned. Suddenly there was a rap on the door and the smile dropped when he opened the door to reveal Mary Cooper, 'Darn, it appears I spoke to soon. Mother, what are you doing here?'

'Shelly, you should be glad to see me here. When you told me that you were back in a relationship with young Miss Penny here, I had to come meet her properly. Obviously you were never gonna come to me, so I figured I'm come to y'all. Now are y'all having safe sex?' Mary asked clasping her hands together and Penny just opened and shut her mouth, not knowing how to answer the brash question.

'Mother! You cannot just turn up and ask if Penny and I are engaging in coitus, you know that I don't…'

'Oh Shelly don't lie to me. When your girlfriend picked up the phone stating you were between her thighs, well I put two and two together. Now I shall ask again, are y'all practicing safe sex?'

Sheldon looked like a kid that had just been caught red handed stealing cookies out of the jar and Penny bit back her laughter, 'Yes, we are.'

'Good, now let me get a proper look at you,' Mary said and Penny stepped forward and did an awkward twirl for Sheldon's mother, 'Oh Shelly, you've got yourself a stunner.'

'Thank you,' Penny smiled.

'Penny, don't listen to…'

'Shut up Sheldon.' Penny said and Sheldon just looked confused.

'So, I knew of you before Penny but only because you were bonking Shelly's former roommate. I didn't really get the chance to get to know you but I guess that's what this week is for. So Penny, what do you do for a living?' Mary said sitting down on the sofa as Sheldon brought in her suitcase and put it in the spare bedroom.

'I'm an actress, at the moment I'm playing Queen Elsa in Broadway's "Frozen",' Penny smiled.

'Wow, well that's quite an achievement you've got going for you.'

'Well, it's nothing on Sheldon's,' Penny laughed and Mary raised her eyebrows.

'What have you achieved that you haven't told me Shelly?'

Penny bringing up his life goal immediately set Sheldon in a good mood again. He was almost jumping up and down in excitement as he spoke, 'I won the Nobel Prize Mom!' Sheldon cried, grinning like a Cheshire cat.

'In your science hocus pocus?'

'Physics Mom.'

'Well congratulations Shelly,' Mary smiled and she hugged her son.

'I'm going to gloat to the others later and rub it in their faces so you can't brag about me to anyone just yet.' Sheldon said smugly and Mary frowned.

'Others? You mean your geeky little friends and the Indian?'

'Mother, you know you're not supposed to refer to Rajesh as "the Indian"!'

'Well, what should I call him then? A Curry Muncher?'

'Or just Raj would be nice.' Sheldon said, folding his arms and Mary rolled her eyes.

'Whatever, let's go out to dinner to celebrate. All three of us!'

'Mooooooom!' Sheldon whined.

'Sheldon Lee Cooper, you are my only son and we are going out to celebrate.'

'That's not true, you have George.'

'Well he's as dumb as soup and will never amount to anything, so in essence you are my only son.' Mary said flippantly.

Sheldon paused before shrugging, 'You're right, please continue.'

'We are going out for a celebratory meal, so put your coat on and let's go!'

'I'll drive.' Penny offered and Sheldon sighed. It was only typical that his girlfriend would side with his mother.

'Fine, but I'm not going to pay.'

'It's on me,' Penny said again and Sheldon glared at her, 'Oh stop being a baby Sheldon, let's go.'

'Listen to your girlfriend Shelly bean; she's got a lot of sense on her.' Mary laughed and despite his protests, Sheldon soon found himself sitting in the back of Penny's car, listening to his mother chat to Penny. Suddenly a massive truck cut Penny up. Swearing, she honked her horn and flipped the driver off.

'I don't think it's wise to make rude gestures at other drivers Penny.' Sheldon said.

'He cut me up!'

'That doesn't matter; you don't antagonise a man whose bumper sticker says: "If you're close enough to read this, I'll kill you".'

'Sheldon, I'd go all Nebraska on his ass if he tried anything. He'd be running scared like a little girl after I was through with him.' Penny said and Sheldon shrugged.

'Well, don't expect me to say comforting words when he turns up at our door looking for a fight.' He huffed and Penny rolled her eyes, choosing not to respond. Instead, she decided to resume her conversation with Mary. Penny parked up on the side of the road and they all got out of the car, 'Penny are you sure you're allowed to park here?'

'Don't see why not, there aren't any signs to say I can't.' Penny shrugged, 'Come on, let's go get some grub,' she laughed taking Sheldon's hand, 'Oh damn it, I've just realised, I can't have anything to drink with my meal… I'm driving.' She sighed and Sheldon rolled his eyes. Penny and her alcohol. When they were seated, they all gave the waitress their orders and made conversation with each other and Sheldon found that he was having a really good time. His mother and Penny were getting on really well and he just watched them in joy as they spoke with each other, laughing and giggling like teenagers. Looking out the window, he chuckled to himself and looked at the menu again to see what he would order for desert… it didn't harm anyone to know his decision prior. That way there wouldn't be a hold up when ordering.

'Sheldon, what's so funny?' Penny asked, raising an eyebrow. Was there something on her face?

'I think you should maybe have that Martini after all Penny.' He said.

'You know I can't Sheldon, I'm driving.'

Sheldon looked back down at the menu and smirked, 'Not anymore… they're towing your car.'

Penny's eyes widened and she whirled around to look out the window to see her car being loaded onto a tow truck. 'Oh shit!' she cried, jumping up and running out the restaurant. Mary looked at her son and smiled.

'Sheldon, don't ever let her go. She's the best thing that's ever happened to you.'

'I don't intend to mom.'

'Perhaps you should pop the question and create some grandbabies for me.' She smirked knowingly and Sheldon raised an eyebrow.

'Marriage? She's only 25 Mom and we've only just got back together, I don't think she'll want to be my wife just yet. Perhaps in the future.'

'Well, don't wait too long Sheldon, she's not gonna be young forever and when it's meant to be, like it is with y'all at the moment, it's never too early to pop the question.'

'Alright, perhaps I will then.'
