Dark At Night
Number 12 Grimmauld place is so very dark at night. So dark that, when Harry woke from his nightmare and headed to the kitchen for a glass of water, he slammed into Sirius without even registering his shape in the hall.
He had muttered a hasty lumos under his breath, and the light had illuminated Sirius' pale face, which was partially hidden by sleep- rumpled hair.
It was so dark at night. So dark that, just behind a bust of Marius Black, No one would see the forms of two people pressed against the wall, their mouths pressed together, hands buried in matching black hair.
It was quiet at night, in the dark; except for soft whispers of "Harry...Harry..." uttered against pale skin and over kissed-red lips and melting into "James...James...", before the breathy words were lost completely to the hard kiss that followed.
Number 12 Grimmauld Place is so very dark at night, and no one saw.
