Lucifer Morningstar

Lucifer and you lived in the blond man's palace, since as the king of Hell he had those privileges. You two had been a couple for a long time (approximately 2-3 years) and always trusted each other completely. He even talked to you about his ex, Lilith, and you, in turn, would make up an ex to tease him—a recurring joke between you two. But even with all that, your relationship was perfect, too perfect to be real, since you were both incredibly affectionate with each other.

One very, very hot day, the two of you planned a day at the pool. A pool that Lucifer had in his backyard where you could relax for a while, just the two of you, as usual.
It should be noted that the pool was very large and very deep on the side furthest from the stairs, which was always a problem for Lucifer.

At that moment, the two of them were changing into their swimsuits together so they could help each other.
