Susan has harboured a secret spanking fantasy for years, but isn't brave enough to discuss it with her husband, Nick. But a fancy dress birthday party helps bring things out in the open. Susan and Nick dress up as naughty schoolgirl and Headmaster, and when Susan's best friend Alison gets a playful birthday spanking, Susan wants in on the action too. She does her utmost to get Nick interested, and although he is strangely reluctant at first, he later proves highly effective in spanking his wife's bare bottom... which adds a whole new dynamic to their marriage, including some exciting role play.
