Harry

I let out a small moan as I opened my eyes, the agony in my stomach increasing. I could feel Carlisle's cold hand brushing my hair back, and he was humming softly. My skin seemed overly hot, and I realised that I was only wearing underwear.

His humming stopped as I turned my head to look at him, his golden eyes darker than usual, his hair a mess. He was also only wearing underwear, but I tried not to think about it.

"Hey," I murmured, trying not to flinch as he placed a hand on my stomach, "How long have I been out?"

"A few days... we didn't know if you'd wake," He said sadly, moving a little closer to me. He reached over me, and I heard the clinking of a vial. I sighed, but I didn't look over to the side of the bed.

He pulled back, and I saw the clear vial with red liquid in it. Pain reliever.

I allowed him to help me drink it, and once I was finished, he put it back, and looked at me, his eyes filled with sadness.

It was then I knew. Someone had died.

The grief filled me, and he pulled me against him gently.

Sobs shook my small body, and he held me close, allowing me to let it out.

"They were using Lily as a test subject. I'm so sorry, we couldn't save her."

I could hear the grief and guilt in his voice, and I relaxed into his embrace.

After a few moments, I looked up at him, my face wet from the tears. Tears were threatening to spill down his cheeks, but it didn't stop him.

"You are so beautiful, Harry," He whispered, leaning down to kiss me. The kiss was brief, and the tears started streaming down his face.

"You are so goddamn beautiful, and I love you so much, and you are never leaving my sight again, ever. Okay?" With each little statement, he'd kiss me, trying to get it through my head.

Carlisle's eyes suddenly lit up, and I knew he had just made a plan. Unfortunately...

"Carlisle Cullen! You are not taking Harry and Bella and running away. It's not happening!"

He pouted a little, and I kissed him, giving him another idea. I knew instantly what Carlisle had in mind once I heard Alice's scream of disgust. Carlisle chuckled lightly, and sat up.

Although tears were still streaming down my face, but Carlisle's version of distraction was brilliant.

He moved me so it was straddling him, and I kissed him again, but firmer than before. His cold tongue entered my mouth, and out tongues battled, his hands pulling on my messy hair.

I could tell he was holding back, not knowing how sensitive I still was. Everything ached, but not enough to stop this from happening.

I could feel both of our cocks against each other, only a few thin pieces of fabric between them.

I slid my hand between us, and slipped my hand into his shorts. I stroked him a few times, before pulling my hand away.

He pulled back, and ripped my shorts away. I frowned, knowing I'd have to replace them, but before I could scold him, his lips were against mine again, and his hand was wrapped around my cock.

I moaned softly, resting my forehead against his, his eyes on mine, completely filled with love.

As I reached for him, he released me, "This is all about you, my love."

He laid me back on the soft blankets, and took off his shorts. He then wrapped my in his arms, before slowly thrusting into me. The pleasure was indescribable.

He was still for a few moments, the feeling of being connected enough.

He rested his forehead against mine as he started moving, keeping his movements slow. I wrapped my legs around his waist, and curled an arm around his neck.

"Oh, you feel so good... mm so tight..."

Carlisle's moans turned me on further, and Carlisle wrapped his hand around my hard length again, stroking me in time with his slow, loving thrusts.

"Carlisle," I moaned, my orgasm building.

His thrusts started to speed up, his moans becoming louder. I could tell he was nearing his orgasm.

"Harry, I... Oh!" I felt his cum filling me, and that took me over the edge, my orgasm traveling right through me.

Carlisle's soothing words of love warmed my heart, and as he slid out of me, he rolled onto his back, and pulled me on to his chest.

"Sleep, love. You can see the others in the morning," He murmured, and I nodded.

He was practically cradling me in his arms, one hand combing through my hair, and one arm holding me, keeping me safe.

I sighed sleepily, and I managed to utter a single request, "Sing to me."

I felt him give a small laugh, before he started singing the song I hadn't heard in years, "I will take
You in my arms
And hold you right where you belong
Till the day my life is through
This I promise you."
