Ne možeš me tretirati ovako, 3. deo

Cherry has been given some lines to write and a time limit. She fails to get them done in time which means a bare bottom spanking. Sarah then announces that she is going to a party and that Cherry must come and wear a frilly pink party dress. Cherry does not want to wear it and stamps her foot and has a tantrum. This leads to trouble as she is then also made to wear a diaper. An embarrassed Cherry also has her skirt pinned up at the back. When they come home from the party it transpires that Cherry has taken a huge piss in the diaper. Sarah cannot believe it and spanks her hard with hand and paddle. Will this naughty girl ever learn?
