Miss Jenn catches her boyfriend, who had snuck off in the middle of the night while she was in bed, red-handed (or rather lube-handed) jerking off to porn. She is furious and decides to take things into her own hands, spanking this naughty young man with Mrs Hairbrush, her antique celluloid hairbrush, making him ask for a spanking and him to tell Mrs Hairbrush what he was caught doing.
