"Oh fuck." Crowley didn't even mean to say it, or for his fingers to tighten in Kol's hair as he encouraged his vampire, relishing in that sweet mix of pain and pleasure that always came from being bitten. He could have quite happily let Kol drink more, and his reactions showed as he pressed up against the other man.
Still, he got a kick from tasting his own blood on Kol's lips as they kissed. "And all the reasons are true." His reply was also mumbled, unwilling as he was to actually stop kissing his vampire for more than a split second or two at a time, because this, this relationship? Was actually addictive. Which probably made it dangerous, but Crowley really did not care about that. Kol just had that affect on him, every time.
