She saw you...

You went to Alison’s room in the nightie. She opened the door and hugged you again. She was already dressed in her office attire consisting of a black skirt and a white blouse. You could see the faint silhouette of her red bra underneath the blouse.

“Good morning sister!” She said as she released you from her hug.

“Good morning.”

“How was your sleep?”

“It was pretty good. But I didn’t have to go to work today, I could have slept more.”

“Great! I’m on morning shift today, what do you want to wear today? I’ll bring you out for lunch.”

“I’ll just go in my jeans and ...”

“Nonsense, you should be wearing a skirt or a dress! Sister.”

“But I’ve not wore a skirt or a dress in public.”

“You did, in La Senza.”

“And you walked back in a skirt. I knew because I saw you through the window.”

“What? I thought I was late enough and no one saw me.”

“You were, until I was looking out at the window because I saw a silhouette of a pretty girl at our lawn, and she happened to walk towards our house. I was curious what she was up to, until she unlocked the door and came in. When she came in, I hid in the kitchen and she went towards your room. I only managed to piece everything together in the morning when I found the skirt in your room, similar to what she was wearing.”

“But I still don’t think …”

“If I thought you’re a girl when it is at night, then you’ve already convinced me well enough.”

“But Alison, I am not ready yet.”

“Fine, we won’t go all out yet. Just trust me! Take a shower and come back with your panties. I'll lay the clothes on the bed by the time you're back. I'll promise you won't be wearing skirt or dresses.”
