You catch one, but the other escapes

The doorway is just a bit too wide. One of the girls, gets by, but you are able to grab the other by the waist before kicking the door closed. Wrestling her to the bed, you drop her on it. Standing over her you notice how young she looks, and how frightened. "What is your name, young lady?"

She just looks up at you, scared to ****. Too scared to talk.

"I asked you a question, and I expect an answer."

"Sally." she whispers, "Sally Mathewson."

"And what do you think you are doing in my room, Sally Mathewson?"

"It was just meant as a joke." she says.

Standing there, arms crossed in front of your chest, you reply, "And a not particularly funny joke at that. Who was your accomplice?" your question is met with silence. "Do you really want to take all the blame for this? I'm thinking that the headmistress won't find this amusing either." Still no answer.

From behind you comes a voice. Female, young, somewhat defiant. "That would be me." You turn to see the other girl in the doorway. "Let my sister go. It was all my idea anyway." She is tall, has red hair like her sister, also pretty, also small breasted, but she fills out her shorts quite nicely.

"And you are?"

"Grace. Grace Mathewson. I'm sorry about this. Honestly, we weren't expecting you until tomorrow."

You indicate that she should sit by her sister, adding, " I really should report you both to the Headmistress."

Grace defiantly interrupts, "Let my sister go."

"That's not going to happen. You TWO vandalized my room. And you TWO are going to answer for it. Come back here after dinner. I will have rollers and paint. for both of you. Now, get out.""
