He stepped off of the painting and kicked it over so Walburga faced the ground,
and neither had to look at her as she screeched from beneath them. Sirius questioned Mia
with a buck of his hips, and she answered with a whimpering moan.
"Oh, kitten. I'm desperate to reward you for what you've just done, you have no
idea how bad," he said, rutting his denim-clad hardness against her.
"Reward? I'm not entirely sure I should be rewarded."
"Why's that, love?"
"I almost set the house on fire," she said, gesturing to the blackened wall behind
him. "Very dangerous. I should... I should definitely be taught a lesson."
Sirius groaned. "Now I'm torn."
"Why's that?" Mia asked as she rolled her hips against him, wrapping her legs tightly
around his waist as she did so, gripping the railing above her to hold herself upright.
He closed his eyes and bit his bottom lip as she rocked herself against him. "I should
punish you for nearly setting the house on fire," he said, moaning when she scratched the
nails of one hand down his chest. "But I want to reward you for getting my mother off of
the wall and for nearly setting this piece of shit house on fire."
Mia laughed.
Sirius grinned and slipped a hand between their bodies, inching her skirt up her
thighs until he could dip his fingers between her legs. When he reached their apex and felt
a bare warmth, his eyes widened. "Kitten? You seem to be missing something."
She grinned smugly, her amber eyes flashing.
"Did you at least wear knickers to the Apothecary?"
Mia rolled her eyes. "You haven't corrupted me that much, Sirius Black," she said
with a chuckle that was replaced with a low whimper when he slipped two fingers inside
of her.
He watched her face with amused concentration as he touched her, grinning madly
when she gasped as he ran his thumb over her clit. "You like that, don't you, kitten?" he
whispered in her ear. "So wet for me. How long have you been planning this very specific
seduction?"
"Years." She whimpered and leant back against the wall, thrusting her chest out
toward him when he hit a sensitive spot inside of her. "Oh fuck—Sirius, there! Right there!"
