Personally, I thought that Bella and Edward should have kept going in the meadow at the end of Eclipse. This is my version of how it happened...

He pulled back a few inches to look at me, and his eyes did nothing to help my resolve. They were black fire. They smoldered.

"Why?" he asked again, his voice low and rough. "I love you. I want you. Right now."

The butterflies in my stomach flooded my throat. He took advantage of my speechlessness.

"Edward," I mumbled against his lips. "Edward, wait. We shouldn't."

"You were eager enough two days ago," he reminded me, moving his mouth to my neck.

"Edward," I gasped. "Your soul. Remember?"

His lips trailed up the side of my jugular, to the space behind my ear. He paused for a moment, and I felt him hesitate. Then he took hold of my earlobe in his mouth. My eyes widened.

"At present," he murmured, "There are far more important things on my mind than the well-being of my soul."

One hand trailed carelessly down from my hair, gliding over my cheek, across my shoulder blade…brushing across my chest on the way down to my waist. I felt my heart stop. Then, suddenly – I wasn't quite sure how it happened – my legs were hitched up around his waist, my fingers tangled in his hair, my mouth on his again.
"Then again," I said into his mouth. "Why wait?"

"My point exactly," he murmured. His lips pressed apart, pulling mine with them, and I felt his tongue enter my mouth. Cautiously, he began drawing patterns across the roof of my mouth. If my eyes had been wide before, they were probably popping out of my head now.

For the third time ever, my fingers wandered down to the buttons on his shirt collar. I pulled the first one open, silently praying that Edward wouldn't change his mind and draw back; but he didn't, and for the second time ever, I undid them all. This time, Edward shrugged out of the shirt himself, shaking it down off his shoulders, letting it drop to the ground beside us. I ran my hands across the perfect, rigid muscles in his back, shivering at the feel of his icy chest against me.

The hand at my waist was travelling upwards again. It paused at the top of my blouse, one finger tracing patterns around the button. Then, with a sudden pop, it had snapped open. My breath caught in my throat. There was second pop, then a third. Then they stopped.

Well, that's it so far...I'll post the rest of it if there's any interest!
