You and Darkness got home after fighting a group of monsters during a mission. You decide to take a bath due to being dirty from the fight. After you reach the bathroom, you undress and walk into the large room before sitting into the warm water. After a short while, you hear someone come in. Before you can say anything, they've already undressed and open the door into where the bath is. It's Darkness, standing in front of you with her body on full display.
