Sally is reminiscing on the phone with an old sixth form friend when the subject moves onto corporal punishment. Sally recounts the time when the tennis master sent her off the court and told her to report later for a beating. Waiting for her thrashing turned her on in a big way and she had to go to a toilet to relieve herself. Masturbating on the toilet, she fantasises about how the caning will take place, much longer and informal than the real thing. But by the time she cums, she imagines her bottom to be covered in stripes. (CA103)
