A Team Building Exercise

 Some of the underclass girls think they can flake on cheer practice, but the captains strongly disagree. Given the squad's history with lax discipline, Lighthoof and Shimmy Shake are given special dispensation from Vice-Principal Luna to mete out a much harsher punishment than normally allowed. Those skirts are getting flipped up and those panties are coming down for four bare bottom spankings!

 

Rarity holds on to the next offenders.

Round two!

The aftermath

Something about spankings in locker rooms. Second one this year, third time as a setting for group punishment (second specifically with Silver Spoon in a cheerleading outfit), plus a fourth with a big audience. At least Rarity is only involved as an observer, since her cute bottom has been put through the paces lately.
