****** Just Like a Bad Girl Should ******

Summary
     Tonks's inability to behave herself lands her in some trouble with
     the Head Boy.
Notes
     Tonks is 15.
"I'll take it from here," Bill said.
The Slytherin prefect looked mutinous. But Bill stared back and after a moment
he shrugged, pivoted on his heel, and stalked away without a backward glance at
the Head Boy or the errant fifth-year he was about to discipline.
"Cool," said Tonks.
Bill did not respond. He didn't even look at her. He simply sat back down at
his desk, plucked up his quill, dipped it into a jar of blue ink, and resumed
the report he'd been writing before the interruption.
He knew that Tonks was looking over his shoulder; he felt light puffs of warm
air on the back of his neck.
"Whatcha writing?"
Bill tried to remember the name of the Ravenclaw boy who'd fainted during Care
of Magical Creatures. Had it been Philip Jones or Ned Jones? There were too
damned many third-year Joneses, and more than half of them seemed to be
Ravenclaw. He tapped his chin with the feathered end of his quill. Maybe it had
been Timothy Jones. Bugger it all.
Behind him, Tonks huffed. "Aren't you even going to ask me if what that idiot
said I did is true or not?"
Bill decided that the fainting third-year had been Gordon Jones, and proceeded
to the next item: Professor Galabran had informed him, somewhat hysterically
after dinner, that his pregnant ashwinder had got loose and that there'd be a
great deal of trouble (namely, the possibility of the castle catching fire) if
she laid eggs before she was found.
"You're not, are you? You're just going to keep writing, and not pay any
attention to me. I'll have you know – no, if you're not going to bother asking,
I'm not going to bother defending myself to you."
Should he bother warning Filch about the ashwinder? On the one hand, Bill
wouldn't weep if Mrs. Norris were eaten by the snake. On the other hand, a
vengeful Filch might find ways of making him weep if anything happened to his
precious monster of a cat.
Tonks was working herself into a snit. "You're a rotten Head Boy, you know.
You're just sitting there with your back to me when – you've no idea if I hexed
that silly bint or not. I might have! It would've served her right. I could be
very, very dangerous. Or I could just walk right out."
Bill aimed his wand over his shoulder and casually uttered a Locking Charm.
"Well, at least you're paying some attention to me."
Her tone softened, became girlish and slightly playful. "If you paid more
attention to me…"
Bill listened, and pretended to write.
"If, for example, you turned around and looked at me," Tonks continued, "it
might be worth your while."
Bill considered, decided he'd strung her out long enough, and set his quill
down. "Describe," he said without turning.
Tonks was momentarily silent. Bill picked up his quill and drew a graceful
curlicue on the bottom right corner of his parchment.
"Well," Tonks said, sounding slightly flustered. "I've taken off my robe and
I've unbuttoned my shirt."
Bill pretended to yawn into his hand.
"Also, I'm not wearing a bra."
"That's interesting."
"My boobs," Tonks continued with a good deal more spirit, "are flawless, as you
know. That's one of the perks of being a Metamorphmagus. I have the very best
boobs in all of Hogwarts. Except for Gwynnie Mowbry, and I'll let you wonder
how I know that. It's a bit drafty in your office so my nipples are quite hard.
I'm touching one of them. Well, first I licked the tip of my finger. Now I'm
touching my nipple. Er, the left one."
Bill sat back in his chair and spread his legs. His erection was already
straining against the cotton of his pants and trousers. He loosened his tie.
"Wouldn't you like to know where my other hand is?" Tonks inquired sweetly.
Bill unbuckled his belt and undid his flies. He was so busy getting his cock
out that he almost forgot to ask, "Where?"
"On my fanny, of course. I'm very wet. I think I started to get wet as soon as
I saw you. You're very sexy when you're trying to be serious." Her voice began
to break. "I'm – s – spreading. Myself. I've got two fingers – ooh."
Her throaty moan was almost too much. Bill licked his palm and wrapped his
fingers around his cock.
"The door is locked, right?"
"Er," grunted Bill. "Fuck the door."
"Because I'd hate for someone to just barge in here and catch me with my tiny,
slimy knob in my hand!"
At Professor Snape's voice, Bill jumped out of his seat, scattering quill, ink,
and parchment, forgetting completely that he had locked the door and that no
one could Apparate inside Hogwarts Castle. He spun around, fumbling with his
robes, and there was Tonks, just bloody Tonks, utterly starkers and laughing
her arse off.
"Fuck." Bill was shaking, but he tried to be casual. "Don't—"
Tonks kicked the pile of her clothes aside and walked up to him. She cupped him
between his legs and with her other hand grabbed his tie and yanked his face
down to hers.
She giggled into his mouth, which was annoying, but her tongue followed the
giggle, so it was all right. He squeezed her arse. Silly little girl. He ought
to shove her against a wall and fuck her blind. He ought to spank her.
He gave her arse a gentle swat, wondering what she would do.
She slipped her hand inside his robes and grabbed his cock.
All right, then.
He gave her another, harder swat. She bit his bottom lip and drummed her
fingers lightly up and down the
length of him.
Reluctantly, he pushed her away from him. She blinked up at him, her eyes hazy
with lust, her lips splotched from his nibbles and making an ‘o’, as if waiting
for a tongue to push past them. Or a cock.
Later.
Fuck, she was young, Bill thought as he took her small hands and lead her to
the chair. He sat down, swept his robes aside, and patted his bare legs.
Grinning, she started to straddle him, but he shook his head and helped her lie
across his thighs.
There was so much grace in the curve of her spine and the way her pink hair
spilled over her neck and shoulders. It was hard to believe that she was so
clumsy almost all the time.
"Comfy?" he asked.
"Not really."
"Spread your legs."
She complied.
One finger inside her, up to the first joint. She was wet.
Tonks shuddered as he penetrated her and wriggled, trying to get him in deeper.
He laughed and almost called her a slut, but he stopped himself, thinking that
that might hurt her. "Wanton," he said instead and that seemed to please her
because she tossed her hair and murmured, "I'm having all the fun."
Bill swirled his finger once, eliciting a gasp, and withdrew. "My turn, then."
And he slapped her arse hard.
"Ow!" Her whole body jerked with his blow.
Bill waited, afraid he might have taken things too far – she was only fifteen,
after all. But then she said, "Well?" so he slapped her arse again.
"Reckon I've been a bad girl."
Slap.
"Very."
Slap.
"So, you do – mmf – you do think I hexed that girl."
"I know you hexed her."
"Oh? How?"
"Because." Slap. "You are." Slap. "A very. Very. Bad." Slap. "Girl."
"You have no idea," purred Tonks.
Bill spanked her until her arse was almost as pink as her hair and his palm was
numb. Then he slumped against the back of the chair and let his arms dangle at
his sides. He felt drained except for the throb of his cock.
Tonks got off him and stood. Her movements were stiff, ungraceful, as if she
were trying on new high heels.
Bill grinned. "Did a number on you, I did."
"You did," Tonks agreed. Then she swooped on him like a raptor, straddled his
lap with her long legs and hitched herself close until he could feel the soft
mounds of her breasts, and the heat of her, lower down.
"My turn," Tonks said.
