Edited Version
Sheldon woke to find they were still entangled under the sheets and smiled at his the sleeping beauty beside him. He placed a little kiss in her forehead causing her eyes to flutter open and she smiled returning the kiss but on the lips instead.
"Shower?" He asked raising an eyebrow suggestively.
"Sounds like fun" She replied winking at him as she crawled out from under the sheets.
Sheldon got up after her and lifted his naked fiancé, wrapping her legs around his waist and carrying her into the bathroom. He turned on the shower and let the hot water run over them as they stood there, clinging to each other like their lives depended on it, lips locked together and tongues dancing. His hands ran up and down her body as he lathered shower gel over her tanned skin. He watched as she washed her hair, suds covering her body as she washed out the shampoo and the familiar scent of vanilla filled the shower.
"Sheldon we'd better get out, we're starting to wrinkle" She said showing him her fingers.
He got out first and wrapped a towel around his waist then held one for Penny and wrapped her in it as she stepped out of the shower. He looked down at her ring finger and admired the way his Mee Maw's ring looked on her delicate finger. They dried themselves, got dressed and went off to do some sight-seeing around the city. Sheldon found a model train store so they stayed there for a while, while Sheldon played with the toy trains. Penny couldn't help but smile at the sight before her. He was beyond his years in some ways yet so behind in others but he was still her Shelly, no matter how much of a whackadoodle he was. They went back to their suite and ordered some champagne to celebrate their engagement and watched the Blu-Ray version of Firely, curled up in a blanket on the sofa. They fell asleep on the sofa like that and awoke the next morning, their bodies fitting together like jig-saw pieces. The phone began to ring, causing them both to wake up
"PENNY!" Amy screamed down the phone.
"Oh hi Amy" Penny replied awkwardly.
"What's this I hear about you and my Sheldon?" She seethed.
"Amy I'm sorry I-I-I just uhm you see" Penny started and then Sheldon took the phone out of her hand and held it up to his own ear.
"Amy Farrah Fowler why are you calling Penny?" Sheldon demanded.
"Sheldon oh hi" Amy replied her tone changing dramatically.
"Amy answer my question"
"Because Sheldon I have heard from various sources over the last few days that you and Penny have been engaging in a romantic relationship and that you have kissed her. Sheldon you terminated our relationship because I tried to kiss you so why are you willing to do so with an unintelligent bimbo like Penny when you could have had something like that with me?" She asked.
"Amy I'm sorry to say that I don't love you but I do love Penny and I am willing to do just about anything for Penny. I would also appreciate if you didn't talk about my fiancé..." He tried to continues but Amy butted in before he could finish.
"FIANCÉ?" She screeched down the phone.
"Is that not what I just said? Really Amy you should see someone about your hearing" He said, rolling his eyes. Penny just watched him.
"Put me back on to Penny" She demanded but Sheldon just hung up.
"I now regret turning our phones back on" He stated handing the phone back to Penny when his own phone started to ring.
"Dr. Sheldon Lee Cooper speaking" He said waiting for someone on the other end to speak.
"Shelly what's this I hear about you whisking that neighbour of yours of to Paris?" His mother asked him. His mother knew about his feelings for Penny as he confessed to her the last time she visited.
"Oh hello mom, what you heard is correct, Penny and I are in fact in Paris"
"Shelly you better not be living in sin" She sighed.
"Mother, Penny and I shall be getting married in August of this year"
"MISSY OUR SHELLY'S GETTIN' HITCHED" He heard his mother shout to his sister "Oh Shelly I'm so proud, she's a beautiful lady and you make sure you take care of her" She said, Sheldon could hear her crying.
"Mom why are you crying? Has something upset you?" He asked, his voice filled with anxiety.
"No not at all Shelly I'm just so happy for you" She said between deep breaths.
"Oh good, Penny and I shall be arriving home this Friday so we may talk properly upon our return" He said, sitting down beside Penny and kissing her temple.
"Alrighty then, you take care of yourself and Penny"
"I will Mom, I'll see you soon, goodbye"
"Bye Shelly"
"Mom seems very happy about our engagement"He said, turning his phone off again and placing onto the coffee table.
"I'll be back in a second sweetie don't move" Penny instructed, getting up off the sofa and padding across the floor into the bedroom to retrieve a box. The box was small and red with a flash symbol on the lid. She hurried back and handed him the box. He looked at her suspiciously as he lifted the lid off and shrieked when he saw the box's contents.
"Penny how did you.."
"Are those the ones you were looking for?" She asked nervously biting her lip.
"Oh Penny I have been hunting down this collection of comics for months, how did you get them?" He asked, looking at the various covers.
"Thank God, I thought I'd gotten the wrong ones" She said, letting out a sigh of relief.
"Penny thank you"
