Based on the Imagine: Imagine Dean cleaning his guns in front of you because he knows that it turns you on.
Idea from the tumblr page of alloftheimagines
You were watching him for now 30 minutes. 30 long and unnerving minutes. And that little shit knew exactly what he was doing. And it wasn't the first time he did that while you were in the same room. You couldn't concentrate on your research anymore; you didn't even heard what Sam was saying all the time. You couldn't watch Dean any longer when he was handling his guns. Suddenly you stood up from your chair, glaring over at Dean as he gave you one of his widest grins as you muttered under your breath. "I have to get out of here." Then you stormed off, you could only imagine the look on Sam's face.
You pushed the door open to your room and just stood there, your eyes closed, trying to get your breathing under control. How could he even know that you loved it when he was cleaning his guns? He looked so hot and content with himself. That's what you liked the most about it. You never told anyone. "Y/N. Are you ok?" You turned around as you heard his voice. "I…uhm, yeah…Why—why not?" You shrugged your shoulders and bit onto your bottom lip. Your eyes roamed over his body. Dean was leaning against the door frame, his arms crossed over his chest, a wide grin on his lips. "You look somehow flustered." He stated.
You turned your head to the side, blushing hardly while laughing a bit. Before you could even say a word, Dean pushed himself off of the door frame, closing the door with one hand. He quickly closed the gap between the two of you and wrapped one arm around your waist, spinning you around.
He pushed you against the wall and looked down at you with mischievous eyes. "Dean…what…" You couldn't finish your sentence as he crushed his lips onto yours. A rusted moan escaped your lips and you grabbed his upper arms for support. Dean cupped your cheeks in his hands and pressed his firm body hardly against yours.
"Dean…" Your words muffled into his mouth as he pushed his tongue through your lips, tasting yours, hot and soft. He broke away from your lips and brushed with them over your cheek, then down to your neck, mumbling against your skin. "I like it when you are flustered…." Dean sucks in one spot of the skin of your neck and started to unbutton your jeans. You ran your hands up on his chest and then slid down his shirt from his shoulders. "…because of me…" You felt him smiling against your neck.
Your moans became a bit louder and your breath got quick and hard. His hands slipped under your shirt and wandered over the soft skin of your back while he catches your lips again in a heated, rough kiss. Your tongues were fighting for dominance but you couldn't win that fight, so you decided to play unfair. You bit him into his bottom lip and he dug his fingers into your back, hissing which made you cause to moan against his lips.
Suddenly there was a knock on the door. You both pulled away from each other, gazing into each other's eyes. "Uhm, Dean? Y/N? Are you in there? I—I think I found something. Come, quick." Sam asked with a stuttering voice. He surely heard you guys. You looked up at Dean, your chest heaving as fast as his. You pushed him away a bit so you could open the door but he grabbed your wrist and pulled you close again. "I wasn't really done with handling my guns." Dean said with a devious grin before placing a kiss onto your lips.
