Author's note: This is my first fanfic, and also my first Supernatural fic, and my first mature fic, so I apologise in advance if I'm not up to the usual standard. I welcome all criticism.

You've been at the Supernatural convention and it's your first night there. You had a great time but your throat is sore from screaming at the opening ceremony. Your friend who is sharing a hotel room with you has gone up to bed and you're alone at the bar pondering whether to go to bed or stay up a while longer and have another glass of wine. You are sipping the remnants of your drink when you feel someone's eyes on you and you look up, only to find that he's not there anymore.

"Do you want another glass of wine, love?" You'd know that voice anywhere. Hell, you've been listening to that voice for months, skipping through Supernatural and Leverage episodes he's in just to hear his deep, sexy voice. Your friends think you're mad because you prefer him over Misha, but you don't care, there's just something about him that makes you want to fall asleep to his voice, imagining what he'd do to you if he ever got those large hands of his on you.

"Um, it's ok, that's nice of you but..." You wonder why Mark is offering to get you a drink, because he must be very jetlagged and you're one of many fangirls at the convention.

"But nothing, I've got this" He smiles. You then realise he's wearing a black suit, black shirt and a grey paisley tie. He's cosplaying as his own character, that makes you giggle a little, that's so unlike Mark, he was wearing a hoodie and jeans just a few hours ago. "May I sit here?" You nod.

"I'm not Mark, I'm Crowley. I used a portal to get through to your world, to gather souls mostly...and, for other purposes,"

You snigger, you know Mark has a warped sense of humour. "Ok yeah..." An actor cosplaying as their own character at a convention...interesting. Also, his minder was nowhere to be seen, that was quite unusual.

"Where's the staff member that's usually with you?" You ask.

"She's stuck in the lift, they're trying to get her out now."

"Shouldn't you go see if she's alright?" You think to yourself.

"Nope, she'll be fine" He smiles, trying to hold back a snigger.

"How the hell did you just do that, Mark?You knew what I just thought. I'm getting a bit scared now,"

"Can Mark do this?" He gestures his right hand and you feel as if you're pinned to the chair, you try to move your arms from the armrests, but they won't budge, as if they are made of lead.

"Ok...this is starting to get really..." You begin to say.

"Look, darling," he purrs with his London accent, "I think you know I'm not Mark. I've been watching you for a while and you seem quite frustrated and bored. How about we take this to my hotel room? I can read your mind, and you've been thinking smutty thoughts about him all evening. I think you know who I am and how I got here"

"Yes, but it's impossible..." You can't believe what's happening, it must be a dream, and yet it can't be, because you usually wake up at vital moments like these.

"Nothing's impossible, my dear," Crowley's voice deepened at the end of the sentence. He loosens his telekinetic grip on you so you can move freely again. "Now, no one's looking, shall we take this upstairs?"

"Well..." You start to answer, but you feel a little dizzy as your surroundings in the bar become a hotel room. You blink slowly a few times to try and focus. You are laying on a soft bed, a cool breeze drifts in from the open balcony door and Crowley is standing next to you.

"I love crossing over into your world and taking Mark's place every once in a while. Oh, the fun I've had with horny fangirls. I can show you, if you like, my dear. If you say yes, you must agree to let me do anything I want with you. That includes pain. That includes everything I've got in store for you." Crowley whispers in your ear, leaning over the right side of the king size bed.

You nod, with a silly grin on your face, wondering what the hell is going on, but, enjoying this all the same.

He then pins you to the bed using all of the strength of his mind, channeling it through his left hand, slams the balcony door shut with a gesture of his right hand. He draws the curtain and then back at you with a sly look on his face.

Quicker than the eye can see, Crowley appears at the left side of the bed and with a click of his fingers you're in your underwear.

"You don't waste time, do you?" You grin. With another click of his fingers, Crowley's suit disappears and he's in his black boxers, with 666 in red writing at the front, you fight the urge to laugh hard at this, and let out a giggle, you feel your cheeks flush red, the wine you had earlier makes you act more relaxed than usual.

"What are you laughing at...gorgeous?" The last word of the sentence, the sexy demon draws out slowly in his distinctive irresistible tone. He leans over you and kisses your neck. "By the time I'm finished with you, you'll be blushing a lot more than that..."
