I melted into him. That's the best way to describe it from my humble, naive point of view. It wasn't scientific at all; in fact, I think most of my brain cells melted along with my lips and body, pretty much all at the same time. He was wrong about not being able to initiate a kiss. I had barely brushed against him when he took over, wrapping his long arms around my waist, pulling me into his form. He bent over me, pushing his mouth flush against mine as I started to wobble backward, one small step at a time, like a clumsy dance with unwilling participants. I don't think either of us knew we were moving; it was just the sheer force of his weight and his persistence moving us in the direction of the wall. Once we got there, Sheldon took full advantage of the instant blockade; there was nowhere to go except further into each other.

Sheldon placed his hands on the wall, using it to steady himself while he kissed me deeper than I knew was possible. His hips moved forward and I felt him hard against me, and that's when both of our eyes popped open. I think it startled us because it felt so good, like nothing we'd ever experienced. More kissing, please. I thought. And more and more. I stared at him with visions of his white board drawings, all the while knowing that I was about to participate in the most extraordinary experiment of all time. And Sheldon was, too.

He was breathing heavily, like an athlete after a run. His eyes were flittering around my shoulders, back and forth, until they finally crept up and locked onto mine. My heart fluttered into my chest and instinctively, I grabbed his neck and pulled him to me. He resisted.

"Wait," he said, his breath close to my cheek. After a long sigh, he slid his hands slowly down the wall, and timidly stepped back. He regarded me, his face flushed, his eyes beginning to show fear. Oh no.

"Don't quit on me, please," I heard myself say.

Sheldon ran a hand through his hair, the strands moving wildly through his fingers. He opened his mouth to speak, but then stopped, before starting again. "I'm okay," he finally said, looking down to the floor. "Just give me a moment."

He took some deep breaths, and I did, too, trying my best to remain calm. I'd experienced arousal before, but not to this degree, and never with the prospect of what was about to happen. My fears from earlier in the evening were now a distant memory, and at this very moment, all I wanted was lose my virginity to the man I loved with all of my heart.

"Let's go to the bedroom," I said abruptly.

Without a flinch, Sheldon nodded his head. "Of course, of course," he said with a sigh, "but shouldn't we discuss the parameters of the experiment beforehand?"

"Oh." I swallowed before answering. "So… what do you propose?"

Sheldon took another breath, his face flushed. "I propose… suggest… propose…" he stammered a moment before locking eyes with me. "Just answer me this: do you require an orgasm?"

I lifted my brows, but remained steady. "Yes," I said.

"I see," he nodded. "And which position?"

With this, I looked away. "Do we have to decide this now?"

"Yes."

I should have known this would happen. My arousal was starting to fade as my brain took over. Which position? I really had no idea. I thought back to the white board. He never got around to the different positions. I wondered what he would prefer. How would a virgin know? Or care? I sighed.

"Let's just see what happens."

Sheldon shook his head. "No, that's not acceptable." He turned his head. "Perhaps I should get my books…" he trailed off, glancing out of the room to the white board. Then he jerked back around, shaking his head violently. "No, no, no… you're correct, Amy. I'm an expert, here, so I should know what is best to do. Perhaps…" He took a long step forward. "Perhaps... I should decide the position as the experiment progresses."

I nodded enthusiastically and he walked back to me, abruptly placing his hands on the buttons of my nightgown. My heart skipped a beat as he began to work them.

"Yes," I heard myself say softly. "Surprise me, Sheldon."

He looked up, drilling into my eyes, and I melted again. The buttons were already undone, so it wasn't long until he brought his hands to my shoulders and pulled apart the flannel. I felt his warm fingers move slowly down my back as he pushed it down, and before I knew it, my nightgown was on the floor in a puddle around my feet. I was completely naked. Sheldon kept his arms around me, and I could feel his chest heave against my breasts. He wouldn't look down; instead, he kissed me and moved us back against the wall.

I was where I was before: brain off, body in control. We pushed into each other with the sensation of my skin against his shirt, and it was almost too much to handle. I kissed harder and deeper, bringing my hands around his neck, pushing my body flush against him. Sheldon responded by timidly moving his hands down, feeling and cupping my bottom as his kiss deepened with trembling lips. I knew he was aroused; I could feel it, so I didn't hesitate to bring my hands down as well, pushing his hips into me.

Sheldon yelped into my mouth and pulled away briefly before bringing his head down to my shoulder, resting there with deep breaths and wandering hands. After a moment, he slowly moved them around and felt my breasts, which caused his body to shudder with an audible sigh. He softly caressed them, bringing his slender fingers between us to pinch at the heart of my bosom, which sent me into such a passionate state that I began to pull on his pants.

"Amy," Sheldon croaked, his head still on my shoulder, "we… we… are making progress."

"Yes!" I exclaimed, as I finished unzipping his trousers and began to caress him, "Do you feel this? Please tell me you do!"

Sheldon groaned like something I'd never heard before. Encouraged, I continued to move my hand, while Sheldon began kissing my shoulder and moving his mouth around to my neck.

"Good Lord, Amy, I do feel it," he whispered after a moment. "I'm having so many thoughts and urges…" he trailed off, moving his head down and trailing his tongue over one of my nipples.

"Sheldon," I breathed as he worked on my breasts. Good God.

Without realizing it, my hand escaped his pants. But I didn't care at the moment. Feelings and sensations were taking over my world, bringing me into a new and exciting place. Suddenly nothing mattered except what I knew would be a pleasurable release.

Sheldon must have been thinking the same thing. "It's time," he said, and suddenly backed away, pointing toward the bedroom. He was adamant, looking as though he were ready to climb a mountain as he shook his finger violently, confidence exuding from every pore of his body. I noticed that he couldn't keep his eyes off of my breasts.

"Let's go," he said hastily, stepping back as his eyes shifted. Then he stopped and looked at me. "You have no idea how much I want this right now," he said.

"Oh, yes I do." I grinned and sauntered past him, pulling his arm along the way. I'm pretty sure I saw a smile on my boyfriend's face as we left the room.

I'm so sorry to end it here. With coitus just around the corner for the actual show, I decided to go ahead and post what I already had. :)
