"Ruin it? Bitch please, I am amplifying it. You can't have sex without a little flavor. I'm bringing the flavor, with a ghost dick." Literally nothing could turn Alec off. If he was aroused, he was aroused and nothing could kill his mood. So naturally, sometimes he forgot that not everyone operated like that. But he was Lenore's now, which meant that she kinda sorta had to accept how ridiculous he was. It was in the fine print.
He did stop fucking around and return to her though. He crawled back onto the bed. "Sorry, sex is serious. Very sensual. I'm being serious." He kissed her shoulder. "Nothing's more serious than glowing dicks," he said. Maybe he did it just because he knew he could, but he managed to make that single sentence sound sensual.
