Backstory: it's no secret that Castiel is the sweetest but hardest working, trusty angel the Winchesters know. He is the ultimate Winchester go to. But he needs some time to relax so you help him.

Your pov:
I was sitting in the library reading a magazine.
When I heard the door open and in burst, the Winchesters covered in muck. they threw their duffle bags on the table and ran to the restrooms.

"Well hello to you too. Love you guys!!" I said sarcastically.

I heard the flap if wings and I smiled when I saw my angel in front of me. I stood up to hug him.

"Hey, babe," I said going over to hug him.

"Hey, honey." He wrapped his arm around me and kissed me.

"Dean and Sam stormed in here without a word. What happened on that hunt?" I asked concerned.

"Oh, nothing just their brother fights."

"Oh well, how have you been? I haven't seen you in a few days hows it up there?" I said looking up.

"We are slowly putting the place back together after Metatron and the darkness being released it's been tough but heaven is being put back together." He sighed.

I wrapped my hands around his neck and smiled. "That's great I knew you could do it Castiel the great angel. My angel."

He kissed me sweetly. " I couldn't have done it without your encouragement."

I looked into his eyes he was tired."Cas you need to relax."

"I'm fine." He lied.

"You are a horrible liar." I laughed,

"No, I'm not I once convinced Sam and-"

"Well, I'm not Sam and dean I'm your girlfriend and I can see right through your white lies you are gonna relax."

"What do you have in mind?"
I smile and grab his hand leading him to our bedroom then I close the door.

I take my pants off then take off his trench coat and shirt.

"Lay on the bed so I can give you a massage." I say seductively.

He takes off his shoes and lays on his stomach." what do I do next?"

I get on top of him and lean close to his ear. "Do nothing just relax don't think about anything." I whispered as I begin to massage his shoulders." Don't think about any cases don't think about heaven just relax think about all the good." I continue to massage him from his shoulders to his bare back leaving little kisses from his neck on down.

"That feels divine." He said in relief.

"I know."

"Yknow you are really good at this."

"Thank you, I was a masseuse before."

"Can you do this more often?"

I giggle. "How often do you think you come down?"

"For as many times I can get you to do this."

"Then you can come down here anytime."

I continued to massage him. Until I heard light snoring.

'Damn I am good.'

I was about to climb off of him when someone opened the door.

"Hey woah!" Sam said closing shielding his eyes.

"Shh relax I'm not naked," I whispered.

"Oh."

"Yea can we talk outside?" I whispered

"Yea." He closed the door.

I slowly climbed off him and put on some shorts and sneaked out of the room and shut the door slowly and quietly behind me.

"Whats up?" I asked Sam.

"Um we have a case and we need Cas to get some info from the golden realms."

"Well he's sleep and he's been really busy and stressed give him a break."

"How did you get him asleep that fast?"

"Massage."

"Damn can you do me?"

"Not like I did him," I said.
