The dark hallway seemed soft around me, all edges and corners slightly blurred by the night. I looked back into my empty room with a small smile and sneaked over the carpeted floor of the Avengers Tower. My white nightgown fluttered around me, making me look like a ghost.
I tiptoed past closed bedroom doors, the warm silence comforting me, only my quiet, quiet steps of my naked feet on the carpet. Finally I reached the right door and carefully opened it. A light breeze caught my hair and my glance set on my favourite person in the Tower.
Loki lay on his bed, huddled in his blanket, only wearing pants. His back shone pale in the moonlight that flew into his room through the open window, curtains flowing in the breeze like always. His hair made a strong contrast to that, laying over his shoulder, pitch black and slightly curly. It rose and fell together with his chest.
I smiled and closed the door behind me. A feeling of triumph flooded me. My secret boyfriend. Only mine. Our relationship was secret, due to a few ... discussions in the team. We wanted to wait until then with coming out. Even if having it like this was also appealing.
I sneaked to his bed and lay down next to him. Loki's face was peaceful, mouth just slightly agape. He held the blanket like he would hold a person. Not gonna lie, I was a bit jealous.
I moved closer to him and put my hand softly on his shoulder. The muscles under his skin were tense, the mission he was on yesterday must have been exhausting.
I examined his face a second time and started to massage his back. It was hard from my position, considering he was facing me and the blanket was scrunched between us. But I managed to massage his neck and let my fingers slowly trace down his spine, caressing all the tense places on the way.
When I let my hand rest on his hip, Loki shifted in his sleep and opened his eyes.
"Well, what do you do here?", he asked smirking, in a raspy voice.
"Massaging you", I answered, also smiling. "But I can stop if you want."
"Hm, don't you dare", he murmured and turned a bit so he layed on his belly. "Please."
I chuckled and rolled over on his back. He made a surprised noise but didn't move. I started to massage his shoulders again and he melted into my touch. I could feel him relaxing under me, as if he was turning liquid.
Loki moaned. "For the love of Frigga, don't stop."
I snickered and bent down to place featherlight kisses down his spine. "You bring your mom into this?"
"Please don't say that. I already regret it."
I laughed quietly. "You tell me a lot of things I shouldn't do. Tell me the things I should." I let my hands rest on his hip.
Loki moaned in protest. "Do the ... make ... please continue. The massage."
I smirked and kneaded the soft skin carefully with my fingers. "Like this?"
He melted again. "Yes."
I continued, amused at how every muscle was relaxed and at the sounds he made from time to time. Loki was so relaxed, I could have easily killed him if I wanted.
I bent down and placed kisses on his back again. Soon I lay down on him and let my fingers wander up to his head, scrabbling through his hair and brushing it against the grain.
Loki let out another tired groan.
I giggled. "You sound like you are coming, my love."
"Feels similar", he mumbled.
I placed kisses on and around his neck. "I love you, I love you, I love you", I whispered between them. "I love you. Turn around. I love you."
"I love you too", he murmured and obeyed to my wish.
Loki changed position and carefully pulled me on top of him, my lips found his in a heartbeat.
We kissed softly, the silence of the night protecting and comforting us again.
"We are the only ones to know about this", I said to him after pulling away after kissing for a minute. My eyes shimmered. "The only ones."
Loki nodded, smiled and put a strand of hair behind my ear. "We are the only ones that can see the others beauty in this moment. And I have to say, I wouldn't trade it for the world."
I smiled at him. "Me too."

This oneshot was inspired by "Sneaking in my bed, are we?" by CunningWriter, who wrote a similar oneshot on my request once. I read it again and was so in the mood that I had to write this.
Have a great week!

And I couldn't leave this gem of conversation unwritten so here a tiny surprise:

Alternative ending:

"We are the only ones that can see the others beauty in this moment. And I have to say, I wouldn't trade it for the world."
I smiled, then I furrowed my brows in thought. "What about Heimdall, though?"
Loki closed his eyes and let his head fall back into the pillows. "(Y/n), not now. Absolutely not."
I laughed, and after a while, he joined.
