After having his fill of Celestia's divine body, Erich lied in bed for a long time. He had no idea how he would explain this to the girl's mother, who was also his lover. In fact, Celestia had even said that she would tell Lunaria. Not that Erich intended to hide the truth from the woman.
While this was technically not his fault, as Celestia had tricked him with a convincing disguise, he doubted the extremely possessive Lunaria would care to hear his side of the story. Thus, he was deeply worried about his future.
Why was it that every time he interacted with this girl, she made his life difficult? This was one of the many questions currently on Erich's mind. Meanwhile, Celestia had not even bothered to clean herself up in the shower. She wanted her mother to smell Erich's scent all over her body, as a further way to antagonize the woman who had stolen the man she was interested in.
