Desmond heard her step, but he didn't notice the way that she was trembling slightly, or he might have stopped. Either way it was probably for the best that he did not... the hunger was upon him. He could feel it, magnifying the emotions that he felt for Raina beyond what they should have been. It was easy enough to control them when he was rested, or when he had the sunlight upon his face, but with the sun not shining in the window at the moment, it may have as well have been night time outside as far as Desmond was concerned. It was painful in a way to see himself react that way, to watch as he had taken advantage of Raina's kindness like that, to know how very easily he might have done something that he could not have taken back. Vampires were that way in a sense... letting their desires control them... he couldn't afford to let his rule him.
"You have no idea what I am going through, Raina..." Desmond growled with a bit of edge to his voice as she tried to make it seem as if he were running away to deal with some sort of problem on his own, rather than giving her space to keep her safe. It was not as if he were going to be starving again throughout the day, he had the blood, he just needed to drink it in peace, to clean himself off and get some peace of mind before talking to her about what had happened. Was it really too much to ask for him to be allowed a moment to get everything back into focus again? He could smell the agitation that was riling her and it put him on edge as well, half tempted to turn around and look at her but he knew if he did then he was going to do something that he regretted... the desire was that strong now.
"Imagine the strongest desire you have ever had, and then try to imagine it mangified a thousand fold over." Desmond said as she put her hand to her back. "The best of us who have the vampiric desires can be around mortals... get close to them, without letting the hunger inside of us change who we are, magnify our own emotions to twist them into something else. But no matter how old, or how strong, when a vampire or a dhampir needs to feed, then that hunger will change them into a monster, Raina..." he growled out darkly. "You have no idea how hard it is to hold my emotions back, or what they could do if freed. You have never seen the remains of a woman literally torn apart by her vampire lover because he thought he could keep himself in control and he could not..."
"Do not... test me..." Desmond growled deeply, darker than he wanted to.
And then he went to walk away from her, not paying attention as he heard footfalls coming from behind him. Instead he popped off the stopper from the bag in a fluid motion and began to drain it at a rate that would likely surprise Raina if she were watching it, the bag shrinking like a poorly tied balloon that was leaking air. He immediately went for the one other one, putting it in it's mouth and draining it without taking a breath until it too had been drained completely. As he was finishing the second one, he stepped into the bathroom, letting the door swing closed behind him, but slow enough that Raina easily slipped in after him without his noticing.The chemicals in the blood back finally hit him as he heard the door close, and he coughed a little and leaned against the wall as he let out a slow groan, pulling open his pants to loosen them for what he knew would come.
Blood drinking, any blood drinking was pleasurable in a way that really defied words for a vampire or dhampir, and most often it was pleasurable for the recipient as well. Having freed the thick burden of himself he shivered a little as he felt it slip out of the confines of his jeans, and then pushed it's way out completely, standing proud there in the cool air. Of course, at that moment, through lust hazed vision he saw Raina standing on the other side of the door, looking at him.
"Raina..." he half murmered, half purred. "You need to go... please... we can talk after the shower..." he whimpered, his breathing increasing to a pant as he looked at her, clearly half overwhelmed with lust.
