As is shown by the SOHF on her face, the young lady in waiting knows that she is in for a very sore future.  And, I am glad to see it.

The girl on the left is looking into the room, though she can’t see what is happening.  She can only hear the swats and her classmate’s reaction. 

She wants to keep from thinking about what is about to happen, but she can’t.  In a few minutes, she will have to walk into the other room, take her shorts and panties down, and bend over for a good spanking.
