You were at her house for a sleepover and you wanted to take a bath, so you told her that you were going to the bathroom to take a bath,she nodded and decided to give you some privacy

You got inside the bathroom taking off your clothes and tied your long hair in a bun so that it wouldn't get wet from the water,after you filled the bathtub with water,you got inside relaxing when you heard the bathroom door open and you saw her wearing a black robe

"Don't mind if I join you,princess?"

You nodded a bit too quickly,you felt a bit embarrassed about that but you looked up and saw her already taking her robe off slowly,you blushed a little but you covered it up with a fake smile not wanting her to suspect you of blushing,she got inside the tub,you couldn't get the image of her naked body out of your head but you're both girls so what's the problem?

"This is your first time? Taking baths with friends?"
