m/m spanking with female witness?

any good stories with teenage boy or young men being spanked by an older man infront of his girlfriend, female friends, female classmates, crush, sister or stepsister etc? preferably with the girls being amused, intrigued or even aroused by the sight and the boy being humiliated.
the boy being spanked together with the girl also works.

“Brought Home by a Cop” by mj2001 is one you’ll enjoy. The protagonist’s female friend who lives next door and has a history of teasing him over his spankings gets to hear the teenage boy crying like a baby. Fortunately for him, she keeps the teasing between them and doesn’t humiliate the guy by telling the entire school, and it’s mentioned that he’s witnessed her ass get tanned as well.

Episode 8 of Skelpay Tales

Author name: Theo Jones

There is a scenario loosely based on a true story whereby a school was having an outbreak of fights in the playground. The Headmaster decided to make an example of two fifth-formers who had been caught fighting and split up by the PE master. The following morning their names were read out in Assembly and they were both given a severe caning during morning break. Their next lesson was a PE period and the master that had split them up decided that everyone in the class should see for themselves the results of being caned by the Headmaster - they were instructed to leave their gym shorts in the changing room and they were made to touch their toes facing away from the whole class including the girls so that everyone could see their stripes. Whilst in position he decided to give each of them an extra six whacks with his size 10 plimsole on top of their cane stripes. Fighting in the playground became a thing of the past.
