Just saw one on Xhamster but cannot find it now! British boarding school. Male student called into the headmistress's office for some offense. She is dressed in conservative business dress, hair up. She tells him to take off his clothes, then tells him to get up on a table. Uses her finger to beckon him close, then grabs his ear and pulls him down onto all fours on the table top. Begins to stroke the back of his neck. Then there is a knock at the door. Mistress tells the caller to come in. It is a female student, dressed in schoolgirl uniform. She has just been made head girl, the Mistress informs the boy. Mistress tells her she is going to punish the male student, then puts on a strapon, bends male student over the table, and pegs, him, while the girl student watches.
