GHB nodded, brushing up against Dylan's left ventricle as he did so. 'Love you.' He raced back up into Dylan's brain, regulating the dopamine release carefully to make sure Dylan stayed as happy and blissful as possible. He split his attention again, pushing enough of himself back into his physical form, enough for him to wrap his arms around Dylan and hold the mortal tight against his body, although part of his psyche stayed firmly rooted in Dylan's mind.
He made sure the dopamine release would remain steady, he tightened the bindings of his addiction around Dylan's receptors and then he backed out with one last whisper of 'Your God.' against Dylan's mind. The mortal would feel as good, but GHB would be free to push Dylan's hair back from his eyes and press a soft kiss to the young man's lips. He did so, of course, and whispered lightly into Dylan's ear in a way that echoed against the substance in Dylan's body. "I want you to be happy. I want you to stay with me forever. I want you to love me like you love no one else."
