Sheldon knew he couldn't miss this opportunity. With Leonard and Amy both out of town for a week, he needed to act. He still could not believe what he was about to do. For most of his life, he had felt no need of romance or any relationship with a woman, but his intellectual bonding with Amy had led him to actually agree to be her boyfriend and eventually tell her he loved her.

The problem was, his love was for her mind, not for her body. He just felt no physical attraction to her. He knew she did not feel the same way. But in becoming involved and thinking about an intimate relationship, he had uncovered something that had apparently long been hidden. He was attracted to Penny. Not just attracted, but filled with desire.

They had always had a strange relationship, but now that he recognized his lust, he knew he wanted her for himself. Of course there was the problem of Leonard and Amy. But he knew they would both benefit from Penny getting with him. It was obvious that Penny and Leonard would not last. Only Leonard's persistence had kept them together this long. Frankly, he could not see how Penny could abide being with him. His faults were manifest both physically and intellectually. He, Sheldon, was his superior in everything. Thus it was only logical that Penny should be with him.

Much the same applied to Amy. Although her mind did set her apart, she had disappointed him that she could not be content interacting with him on an intellectual level. He had no doubt she could find someone who could satisfy her lesser urges. Someone not as selective as himself.

Although he was sure that Penny could not be satisfied with Leonard, there still remained the problem of how to approach her. He had no doubt she would come to realize that he was what she needed, but still needed a plan to proceed. This week would provide an opportunity to make her know what he already did, they were meant to be together.

Penny watched as Leonard finished his packing for his trip. For not the first time, she wondered how she had arrived where she was. How had she ended up with a man like Leonard?

Oh, in a way she did love him, but as she had once told Bernadette and Amy, it was a boring kind of love.

She had to admit that Leonard did care for her and tried to make her happy, especially in bed. But no matter how he tried, she still felt that something was missing. Maybe it was his stature, after men like Kurt, it just lacked something. Maybe he was just too nice and obliging.

Sighing, she rose as he finished up. She returned his kiss and told him to be sure to call her. Telling him she loved him as he headed for the door, she sighed again when he was gone.

She was relaxing, sipping a glass of wine and watching TV when she heard Sheldon's knock on the door. She got up, wondering what he wanted, and answered the door.

"What do you want, Sheldon?"

"Both Amy and Leonard are gone."

"So?"

"I thought perhaps you would want to join me for supper, we can order in. Your choice."

Penny couldn't put her finger on it, but there seemed to be something off about Sheldon. Shrugging, deciding she was hungry, she said, "Okay, how about Chinese?"

Sporting a weird smile, Sheldon said, "Wise choice."

Now, Penny wondered what the hell was going on. "What's going on Sheldon, your acting even weirder than usual."

"Nothing, I just wanted to spend some time with you. Since we are both alone."

Wearily, Penny said, "Whatever. Let's just go order something, I'm starved."

After the food had been delivered and they had eaten, Penny started to head back to her apartment when Sheldon asked if they could talk.

"What do we have to talk about?"

"I was thinking of discussing you and me."

Penny stared at him wondering what had gotten into him tonight, "What about you and me?"

Signaling for her to sit down on the couch by him, "About our relationship."

Penny, who had warily sat down, "What relationship? We're friends."

"Is that all? After all, I have seen you naked. We once took a love test."

Penny was completely bewildered, what the hell was going on? "You saw me naked because you peeked. And the love test proved we were just friends."

"But you did say you felt closer after that test."

Penny had enough, "Okay, Sheldon, what's going on? What is this all about?"

Penny was amazed to see Sheldon actually nervous and a little unsure. But then he said, "I have discovered that I have feelings for you, romantic feelings."

Penny just stared, what had he said? "YOU have romantic feelings for me? What the hell does that mean?"

"It means I want to have you for a girlfriend, I want to have coitus with you."

Penny couldn't help it, she had to laugh. But when she saw the look on his face, she sobered up. "What do you mean you want to have coitus with me? You and Amy haven't even done it."

"I don't want Amy, I want you."

Penny was completely stunned. She had no idea what to do. Sheldon moved over and grabbed her hand. She pulled it back as if it were burnt. "I don't know what's going on with you, but please stop. You and I are never going to have sex."

"Why not? I am taller than Leonard, much smarter than Leonard, do not have Asthma and can eat dairy foods."

Penny started to get ready to leave when Sheldon stood up and putting his arms around her, kissed her on the mouth. Penny was so caught off guard, she didn't react for a moment, then turned her head. Sheldon was persistent and kissed her again. Penny knew she should push him away, go Nebraska on him but she was still in shock and as he continued to kiss her, she began to kiss back. Then she pushed him away. "What are you doing?"

"I am kissing you. I am attempting to have coitus with you."

Penny knew she should leave, but the whole situation had completely thrown her off guard. And worse of all, the kisses had started to incite pleasure in her. "We can't do this. There is no relationship between us and how about Amy and Leonard?"

"I have decided I want you, not Amy. It would be cruel to let her think I would ever want her. As for Leonard, we both know you two will never last, you have dumped him more than once."

"Listen, Sheldon, this is not going to happen. First of all, I don't want you and second, unlike apparently you, I do not intend to hurt Leonard and Amy."

"Isn't it better to hurt them now, instead of after giving them more hope. We are meant to be together, not with those two. We are superior to them in every way. It is only logical we should be paired."

When Penny shook her head and turned to leave, Sheldon stunned her by coming up behind her and putting his arms around her, placed his hands on her breasts, softly squeezing them. Again, Penny was so shocked she didn't react immediately. Sheldon whispered in her ear, "Remember when I did this before. But then there was nothing but skin."

"That was an accident," Penny said as she attempted to leave his arms. She should have been able to easily do so, but maybe her heart wasn't in it as he continued to fondle her.

"Maybe at first, but I knew what I was doing and did not move my hand." Then to her surprise, he spun around and again kissed her, but this time she responded and allowed him to hold her closer.

Then she pulled back and tried to say something, how wrong this was, but then his lips were back on hers. Then she realized he was beginning to unbutton her blouse; she managed to say, "We can't Sheldon, I am in love with Leonard."

Sheldon continued to unbutton her blouse, "Yes, you may think you love him but it's because you pity him, because he works so hard to please you. But he is not what you need, you need me."

His hands continued to work on her blouse and Penny wondered how this had happened. How could they have gotten to this point and so quickly. She realized there had always been a strange sort of attraction between them. She also realized she had often wondered what it would be like to break down that veneer that surrounded Sheldon. To have him sweat, to feel.

Now her blouse was open and it was apparent she wasn't wearing a bra. He leaned down and put his lips on her breasts and she felt herself push against him. She knew she was cheating, that she needed to stop, but something was driving her on. Then he was leading her to his bedroom and she found herself naked on his bed. When he then disrobed, she discovered that was something else about Sheldon. He was more than well endowed. Now Penny took over and helped Sheldon as they became one.
