Shadow's breath was knocked out of him as he was thrown against the wall by a large paw. Inwardly, he cursed himself for not noticing the light of the full moon coming out from behind the clouds. The moonlight outlines Sonic's silhouette perfectly, and the snarl is so close to his ear that he can feel that heavy breath against his neck. Shadow could struggle if he wanted to, but the blow to the wall knocked his breath away.

Familiar emerald eyes are feral as they leer at him from beyond the darkness, the clawed hand keeping him pinned down. Oh God, that strength is something Sonic had never possessed before. It makes Shadow shiver in anticipation, licking his lips as he opens his eyes to stare evenly back at the werehog. Lips curl back over deadly sharp canines in a smirk, the monster's nostrils flaring as he takes in Shadow's scent, mixing it with another's.

All of a sudden, Shadow's lifted from the wall and thrown into the air, then pounced upon like he's some kind of toy. Sonic's large paws are holding him down and Shadow can feel teeth digging into his shoulder, marking him, claiming him. He gasps as they break skin, feeling blood bubble up and spill over into his fur, staining it crimson. Sonic pulls back, as though pleased, and licks his lips before turning Shadow around.

It's rough, hard and fast - just the way Shadow likes it. He can barely find the breath to, but he moans occasionally, pressing back against Sonic's furry body as the werehog rams into him. Nails dig into his thighs, creating half moon circles but Shadow barely notices the pain as his rival takes him again and again, in different positions throughout the night.

Shadow knows Sonic will blame himself later, will be so utterly humiliated that he let himself go, but Shadow can't find the heart to tell him that he likes taking it from his darker half. So he'll let Sonic wallow in self-misery, but come back when it's time for the next full moon.

He always has, and he always will.
