SIN
He fights against mine for dominance, and I let out a throaty sob, wrapping my arms around his neck to pull him closer.
The metal of his lip is cold against my lips, and a shiver runs down my spine from the contact; my core burning with the need for him.
I groan against his lips as Sin pulls my bottom lip between his teeth, before sucking on the flesh, and in a strange way; that burns right across my body.
