A/N: Just a quick, unapologetically smutty, story with Spankward and Slutella

I walk into the room slowly. I know Headmaster Cullen has been waiting for me, and he is not a patient man.

"Late for detention? I would laugh at the irony if you weren't jeopardizing your future, Miss Swan."

My shoulders slump. I hate disappointing him. "I'm sorry, headmaster. I know I've been naughty. I'm trying to change, really I am."

When I look up at him through my eyelashes, he is smirking. "You're not sorry at all. You're late to all your classes because you're fucking your classmates when you should be in class." I gasp at his harsh language and he laughs. "I'm willing to bet that you don't know that you're fucking complete amateurs. They can't give you what you really need."

I look up through my eyelashes again, this time grinning mischievously. "And I suppose you can, sir?"

His eyes grow dark and a bit cruel. "What you need is to learn some respect. Come here and bend over."

He rummages in his closet as I silently do what he asks, slightly afraid of the consequence of disobeying him. Then, with no warning at all, a sharp stinging blow slaps against my ass. I cry out at the pain.

"Not good enough," Headmaster Cullen says. He flips my skirt up. "Knickers off."

I know this is not part of protocol, but he's using that voice again, the one that tells me I'll regret it if I don't obey. As I pull my knickers down my legs, I realize their soaking wet. So does he.

"Are you enjoying your punishment, little slut?" I can't help rolling my hips against the edge of the desk in answer. He chuckles cruelly, then spanks me again and again. By now, I am all but crawling across his desk. With every blow, he pushes my hard nipples and clit into the rough wood of the desk.

He is muttering to himself as he punishes me, and if I listen closely, I can hear what he's saying. "Fuck your ass looks beautiful up in the air like that and so red. And you're sopping wet too, you little whore."

Once I hear what he's saying, I can't stop myself from coming hard, all over his desk. My pussy clenches hard, grasping for a cock that isn't there. And then suddenly it is. The Headmaster didn't even bother to take his clothes off, just unzipped his trousers and slammed his hard cock into me.

I howl with pleasure, still coming, my back arched and toes curled as he begins fucking me mercilessly from behind. His hands grasp the edge of the desk on either side of my head, using it for leverage. He's fucking me so hard that the desk begins bucking with us, making increasingly loud noises, noises that almost drown out my screams and his animalistic grunts.

I am so close, I can barely keep myself from coming, but I need one more thing - permission. "Please," I beg, "can I come, sir?"

He moans a yes, and I come hard, tightening in a vise grip around his cock. I ride it out, pushing myself back, taking him as deeply as I can. Suddenly, he flips me over, pulling out so fast that I whimper. My breasts jut out at him, and he comes, ribbon after ribbon adorning my tits.

I scoop some of it onto my finger, running it along my bottom lip and then licking it off. "I don't know if I learned my lesson, sir."

The headmaster sighs. "Looks like I've created a monster."
