As she began to wiggle out of her jeans, Lucifer stood and did the same, largely because he was well aware that if he watched her do so he would probably suffer a heart attack. Assuming he could suffer a heart attack. Assuming he did, in fact, have a heart.
He was naked and she was naked and beautiful. Lucifer stared for a few moments, almost inclined to giggle. This was... magnificent. He took her hand and pulled her to him, inadvertently prodding her in the stomach. There was that urge to laugh again, but he suppressed it. Instead he ran his hand down her back and over her backside, kissing her deeply before pulling her onto the couch with him.
