A/N- I'm Back! It's time to finish the story. I'm sorry I kept you waiting so long. School kind of got in the way... but I won't go into detail, I rather just deliver the end to The Wet T-Shirt Hypothesis.

I've changed my mind on how the story would end. The girls night and laundry chat won't be happening. I hope this is preferred.

Warning includes parts of M-rating.

The Final Chapter - The Shirt Returns.

*Penny's Apartment*

Amy stared awkwardly into her wine glass, as she made it move and watch the swirls. She hadn't even took a sip. Bernadette and Penny realised the strange behaviour but every time they asked they got the same response "I'm fine". The typical lie of women when something is going on in their mind but they have no need to share. So they decided to keep each other company and chatted away.

The truth was though Amy was far from upset she was so happy but couldn't help think of Sheldon and the kiss. She thought she could wait for sex but after the kiss she only craved it more.

Amy turned her head for the 6th time that night. 8:17pm. Sheldon would be in the laundry room by now she thought to herself.

She placed her wine glass down on to the coffee table gently trying not to bring attention from the two girls. Amy picked up her bag and jacket and descended down the stairs, two steps at a time.

*The Laundry Room*

Sheldon was in the laundry room exactly on time, just like every other Saturday. Except this didn't feel like the typical Saturday for Sheldon. The memory of the kisses still flashed across his mind as if it was a dream he never could forget, not like he wanted to forget either. When it happened he didn't have the chance to think about it just crave it but now that it is done he can think about it but yet he still craves for more. More than he thought he would crave. Sheldon didn't just want to kiss her lips, he wanted to kiss her cheek, her neck, her tender breasts... the list could go on. Sheldon wanted all of Amy.

Suddenly the laundry room door swung open and in came Amy looking radiant as ever. Sheldon didn't have a chance to speak, Amy launched herself into Sheldon's arms and kissed him passionately. There they stayed kissing till the laundry was done. Amy stood quietly as Sheldon folded his clothes his typical way.

Sheldon didn't quite understood what just happened. One minute he was thinking of her the next she was there, all over him. He just hoped it wasn't a dream; it couldn't be, he thought, it felt so real.

Amy was the first to speak, her voice was so quiet if Sheldon didn't have his Vulcan hearing he would have never understood. "I'm sorry."

"What for?" Sheldon questioned.

"For launching myself onto you, it was out of character and I just hope you can forgive me." Amy answered.

"I can't forgive you Amy... There's nothing to forgive you for. I admit I wanted that, I needed that but I also need more." Replied Sheldon. Amy had a puzzled look upon her face. So Sheldon decided to explain further. "It seems I'm no different to the ordinary homosapien, I lust for another just the same. That came more clear after the kiss. Amy I know you've dreamed of the day I would be ready..." He turned to face her. "...That is today." A huge smile grew on both persons faces.

Amy reached her hand out to Sheldon. "Then let's make this dream come true then." Sheldon took it happily and grabbed his clothes basket and they made their steps up to his apartment.

Leonard was in the kitchen when he saw the pair enter. "Oh, hi Amy."

"Hello Leonard" Replied Amy, not taking her eyes of Sheldon.

Sheldon spoke "Leonard if you could please excuse us for an hour."

Leonard was confused, but walked out unsure on where to go.

Once alone Sheldon escorted Amy to his bedroom. Amy laid on the bed and Sheldon followed after her. They shared kisses for so long. So many, all different. Small ones, big ones, deep ones, shallow ones but each was passionate, unique and pleasuring. Amy whispered in Sheldon's ear. "Are you sure you want this? Are you not just going crazy?"

Sheldon replied in a husky whisper which caused Amy's ovaries to quiver in excitement. "I've told you Amy, I'm not crazy, my mother had me tested." Sheldon unbuttoned Amy's blouse, her cardigan was long gone. He went slow making sure to be gentle. Once unbuttoned he pulled her free from it. He starred awkwardly at her bare skin all that was left was the bra. However before he could unfasten it, Amy leaned closer and pulled Sheldon's flash T-shirt over his head and threw it onto the floor, she was sure she would be in trouble after this but she didn't care.

Amy stroked her hand over his bare chest and leaving it on his small part of chest hair. Sheldon couldn't wait any longer though so he unclasped her bra. It was a struggle at first after all he never undid one before. However he got there in the end and he watched it trail off. Her breasts were on show and in his face, he never thought they would be so perfect and that him of all people would be so attracted to them. His penis had been erect since they began but now it was throbbing, just waiting to enter her. Sheldon whispered for the final time to Amy "I'm ready."

They finished undressing each other and Amy placed an condom on Sheldon. They stole it from Leonards draw just beforehand. Sheldon towered over Amy's lying body and she braced herself for contact as his penis enter her. Amy felt more pleasure than ever and slight pain as her virginity slipped away.

The continued entered and exiting, moaning and screaming to the pleasures till they reached orgasm and passed out.

The next day Sheldon was in the kitchen making his Sunday breakfast for him and Amy. Leonard didn't return last night, so he assumed he was at Penny's. Amy woke up when she could smell the delicious food. She realised she was still naked from the night before. So she picked up her panties placed them on and just next to her foot was Sheldon's flash shirt. It was slightly wrinkled but she placed it on it fit her the same and she wore it as a nightie and exited into the kitchen. She paused at the door when she noticed Sheldon's eyes on her and a smile crept onto his face and he spoke.

"I've always liked you in that shirt."

A/N - So that's it. I hope you enjoyed I would love to hear your response. This was a great experience. Thank you!
