Lullaby(Thor and Loki's Sister)

Big Trouble

I opened my door and smiled at Thor. "Hey, what's up?" I asked trying to keep my breathing under control. 

"Steve is needed in the lab." He said. Steve smiled and fixed his hair. 

"We got carried away in conversation." He said looking at me. Thor nodded and stepped out of Steve's way. Thor grabbed my arm and looked me dead in the eye. 

"What actually happened in here?" Thor asked. I felt nervous, but I lied. 

"We got stuck in conversation. Like he said." I kept my eyes on his so he believed me. 

"You lie. Just like other brother." He said. He pushed me out of the way and saw the bed. He lifted up my bra and he glared at me. 

"That's been there." I said, still lying. He grabbed my arm and lifted my hair. 

"What is this mark of teeth?" he asked. He held up my small mirror and I saw a small hickey. I couldn't lie anymore. He was on to me. 

"Fine. Me and Steve did have sex." He let go of my arm and stormed down the hall. I ran after him as he opened the doors to the lab. I grabbed his arm and tried to stop him. 

"Thor stop!" I screamed at him. Everyone looked and tried to hold him back. He kept his gaze on Steve and everyone realized something happened between me and him. Tony walked to him and patted his shoulder. 

"Good job man." He said. He looked at Thor and Thor threw everyone off of him and he grabbed Steve and lifted him in the air. 

"I'm taking my sister home. Now." He said. He dropped Steve and grabbed my arm. He lifted his hammer. I scratched his arm and he let go of me. 

"Why would you do that with him?!" Thor shouted at me. He cornered me. I closed my eyes waiting for the worst, but it didn't come. I slowly opened my eyes and Thor was gone. I looked around. Everyone looked at me in shock. 

"Where did he go?" I asked, I met Steve's eyes and he shrugged. 

"He just left right after he realized he scared you." He said. I touched my chest, my heart was glowing, right through my skin. 

"What's going on with your heart?" Natasha asked as she ran to me. She grabbed me and supported me as I collapsed. 

"It must be her lack of ability." Thor said standing at the door. 

"What does that mean?" Steve asked running to my side. He helped Natasha keep me up. 

"It means, she is getting weaker. She needs to go home." Thor said sternly. He grabbed me and touched my heart. "Her crystal is running out." Right after he said that, I collapsed completely, as the world went black.
