It didn't feel erotic at all.

Maybe it was because of your relationship- how Denji saw you as his younger brother, and nothing more. He saw you like family- so when you asked to take a bath together because you were scared the Darkness Devil would get you..he agreed.

Denji was sitting behind you, smothered against the back of the bathtub. You were leaning back against his chest, and, he sat silently. Him and Aki had been taking care of you for the past few days- he didn't mind this.
