Sirius's eyes widened in disbelief. "I didn't leave you; you left me!"
"I didn't do it on purpose, you prat! I didn't have a choice! And I was trying to tell
you, but you got your knickers in a fucking twist and flew out the bloody fucking door!"
Harry stood still in the corner, feeling confounded by the scene that was unfolding
before him. All he knew was that Hermione had been wearing a simple modest Muggle
dress when she left them earlier, and now she was now wearing... He purposely moved
his gaze away from her legs, instead, squinting at her hair, which looked bizarrely longer.
An irrational thought crossed his mind as he questioned whether he had finally gone barmy
in the head. "Remus?" he whispered uncertainly as the man came to stand by his side.
"It's best to just let it ride out," Remus advised.
"Remus, Hermione just said 'fuck.'"
"Yes, she did."
"And a large number of other swears that I've never heard her say before." Harry
hesitated. "Hermione never swears."
Remus snorted. "She does now."
"Ow!" Sirius shouted as Mia descended upon him again, hitting any body part that
became available to her. "Bloody woman, stop fucking hitting me!" he protested, lightly
swatting at her flailing fists.
She paused, her brow raised as she dared him, "Give me one good reason why I
should ever stop hitting you!"
Sirius grinned at the wild look in her eyes. "So I can do this." He grabbed the back
of her head, fingers entangling into her hair, and tugged her to him roughly. She growled
at the manoeuvre, and he would surely get smacked again for it later, but he crushed his
lips against hers before she had the chance to start yelling again. Merlin, the taste of her.
His fingers relaxed in her hair, though he held her tightly against him with one hand,
the other roaming down to her waist. He pulled her hard against his body, so she could
feel just how much he had missed her.
Mia whimpered in response before opening her mouth to him, pressing her lips
hard against his. When he groaned as her tongue swept into his mouth, she hitched her
legs around his waist with minimal effort. Sirius responded immediately, backing her into
the nearest wall and pinning her against it, making the paintings around them shake. He
continued to devour her, gripping her arse with both hands.
