The dog followed the wolf into the hidden room, nipping at dragging heels with an anxious whine. The sun was rising, they didn't have long, already the pelt of the wolf was rippling with the coming change. Safely indoors and out of sight, the wolf turned, snappinggrowlingsnarling at the dog as bones creaked and reshaped, a wolf turning to a boy, a dog doing the same.
Remus crouched on the floor, panting, his face frozen in an almost snarl, more wolf than boy. Sirius stood, stretching cramping muscles, unaware of eyes roving hungrily over him, more boy than wolf.
'Padfoot...' a husky growl.
Sirius looked over, breath hitching at the sight.
'Moony.' he murmured.
Remus pounced, lupine agility, knocking Sirius to the floor with a thud. Desire unable to be dampened. Teeth and lips and tongues collided, roamed. Breath came in hot pants, hitched gasps.
'Sirius.' Remus whispered to heated flesh.
'Remus.' Sirius whispered back, hands grasping tightly.
Moony growls, Padfoot whines, submitting. Teeth on his neck, sharp but not damaging. Shivers down his spine.
'Mine.' Remus says.
Possessive, aggressive. RemusMoonyRemus. Blending into one.
'Yes.' Sirius gasps. 'Please.'
Losing control. Dogwolfboy. Wild and free. Teeth and nails and lips and tongues. Sweat and salt. Remus comes back to himself, wolf retreating, every inch of him pressed to Sirius. Eyes widen, body tenses. Content and conflicted.
'Please...' Sirius moans.
Fear and lust and confusion. Wolfdogboy. Sirius arcs his back, responding to fingers, mouth, Remus. Remus has Moony under control but can't stop, won't stop. Remembers teeth on throat and ownership and red lust.
'Mine.' He growls in his own tone.
Sirius smiles, recognising the change, writhing beneath him.
'Oh, yes.'
