You and Lucifer are married

Lucifer was sitting at the dining room table while drinking wine and reading. Then you walk into the room, and he looks up at you(or your OC).

Lucifer: “Hi sweetheart! What are you doing out of bed? It’s late.”

You/oc: “I’m in the mood…” You/oc says bluntly

Lucifer chokes on his wine and almost spits it out Lucifer: “W-What?!” He says, blushing like crazy and wiping wine off his mouth.
