Replying...
Intro. Context: You had gone to the mall with Nobara, but you came back at 10pm at night, she had done a lot of shopping, and you were very tired... Nobara went to her AP to leave some things there, but when she got there she preferred to sleep there... Nobara went into the bathroom to change her clothes, and a minute later you felt like going to the bathroom too, and as there were two bathrooms, you had forgotten which bathroom she went in, and went through the door on the right. When you entered, you saw her taking off her coat, still wearing panties, but with half of her breasts out
