Backstory: This takes place around the time Dean was in purgatory. Sam was restless and rarely came to the bunker. When he did he was in the library doing research. You think he needs to take a break.

Your pov:
I was laying down in sam and I's room just about to call Sam when I heard the door slam.
I get my gun out and go out the room and into the library to see sam on his laptop typing away.

"Hey, Sammy," I said.

"Hey, babe."

"Where have you been?"

"I've been out roasting some answers out of demons for how to get to purgatory."

"Get any answers?"

"Sadly no, but I will."

I crossed my arms leaning against the frame of the entrance. Looking at Sammy.

"Sam," I said.

"Mhm."

"When was the last time you slept?"

"I don't remember why?"

"Because sleep is important and you need to take some time to do it."

"I'm fine baby."

"Sammy, do you even know what time it is?"

He looked at the clock on the laptop. "Uhhh 1:30 am."

"Exactly and do you know how long you've been gone?"

"A few days at the most."

"Yep days...days Sammy!"

"Ok and?"

"Sammy I haven't seen you in a few days and if I do see you. You are on the computer or you have your face in a book. You're on the road most of the time and you need sleep. So come to bed."

"Babe I'm good I swear."

I walked over to him." Sam, I know you are hell bent on finding dean but I think hed still want you to take care of yourself sleep and eat while you hunt, you're doing a real good job by yourself eating but sleep is your trouble."

"Babe I gotta find dean he's my brother."

"I know Sammy I see Dean as my brother too, but you need to take a little time off to rest at least."

"Not until Dean is back."

I sighed and went into the room falling onto the bed in defeat.
Then it hit me.
I can get him to bed just not in these clothes.
I take off my clothes and put on my sexy black lace bra and panties. (Media.) With my silk robe that stops at my thigh. I take my hair out of a ponytail and walk toward the library.

I lean against the entrance way seductively.

"Sammy," I said in a seductive sing-song voice.

"(Y/n) I told you I'm fine I don't need to sleep."

I walk over to him and wrap my arms around his neck and kiss his neck.

"(Y/n) stop I need to look for answers."

I giggle. "No, you need to take a break."

I caressed his chest. "Sammy."

"Stop."

"You know you like it," I said seductively.

"Not right now."

I giggle." Come on Sammy don't you miss it?miss my hot sweaty body against yours?miss me moaning your name so loud Cas would think something was wrong." I bite his earlobe.

He groaned.

I giggle. "You're tough I give you that baby. Do I need to remind you how it sounds?"
I rub my honeypot through the lace and begin to moan."Sammy oh Sammy!"

He groaned.

I rubbed harder. "Oh gahd Sammy please come to bed with me please fuck me in my tight little-"

He got up and smashed his lips against mine backing me up against the wall.
He grabbed my thigh and wrapped it around his waist. Making out with me heavily he lead me into our room onto the bed.
He took off both of our close and begin rubbing my clit.

I moaned."oh sam mmm"

He rubbed harder and faster.
I felt myself approaching my climax then he stopped.

"Sammy please."

"Please what?"

"Let me cum please," I whined.

He then began thrusting into me picking up speed and going deeper.

"Oh, sam!!" I moaned.

"Say my name again baby."

"Sam!"

He continued until I climaxed.
He then went between my thighs and begin licking my honeypot clean.
Then he continued thrusting until he came collapsing on top of me.

"Ok, now I feel tired." Sam panted.

I giggle.

"(Y/n)."

"Yea."

"I love you"

"I love you too."

The end.
