Those wondering about the infernal device that Penny was sitting on in the latest installment, might be interested to see what a sit-upon enema cushion looks like. A bit of googling leads me to believe this is a modern remake of a design (the JBL Cascade) that was popular in the 1930s.
It’s almost as if it was designed as a seat for smacked bottoms. The sitter’s sore bare cheeks in contact with the hot rubber surface, meanwhile the thick black nozzle stretches her bottom hole wide, and the spigot rod juts out between her slit, rubbing against her vagina every time she squirms.
Can you imagine being sent to the school nurse’s office for that kind of Sit Down Dance?
