He hovered over her for several more seconds, stuck in his own head, and Mia
clearly misinterpreted his striving to master his primal urges as hesitation.
"Get off."
Sirius looked up at her in confusion.
"Roll over," she corrected.
Sirius obeyed her and did as she said, rolling onto his back.
She sat up and reached for his shirt, lifting it up and over his head and tossing it
over her shoulder. Smiling down at him, she angling forward to brush her lips against a
nipple. He shivered, and she grinned. She kissed the tattoo of her name on his chest, there
above his heart.
He tasted like sin.
Exploring him, Mia took note of each new tattoo and scar that she did not
remember. On every new mark, she placed a kiss; on each familiar one, she nipped lightly
and then tongued over the bite. Sliding slowly down his body, she knelt between his legs
and reached for the buckle of his jeans.
Sirius had ceased all movement and noises, and when she looked up she noticed
that he had stopped breathing as well. Mia quickened her pace in an attempt to make sure
he did not pass out from lack of oxygen, opening the trousers to reveal his mouth-watering,
swollen length. Her heart beat inside her chest at the sight, and she grinned smugly when
she saw his fingers gripping the bedsheets in needy anticipation. She bent her head forward
and circled the tip of his cock with her tongue in movements she had long ago perfected
and he had clearly since forgotten. By the relieved sound of his loud exhale, she could tell
that the memories were returning to him.
When she parted her lips and took him completely into her mouth, sliding down
his length until he reached the back of her throat, Sirius moaned and cried and whimpered
in a way that made her realise how she would make it all up to him—the secrets, the lies,
and Azkaban. He would never have reason to doubt her again, to doubt that she loved and
desired him despite everything they had been through.
When she sucked particularly hard on an upstroke, Sirius let out a long, drawn-out
"Fuuuck," followed up by blaspheming the names of Merlin, Circe, Godric, and every other
famous witch and wizard all the way down to the Wizard of Oz. A very small part of her
wanted to smugly remind him that Oz was not a real wizard.
