TURA-288 - Educational mom whose weakness was seized, blackmailed principal's office

Twenty mothers are blackmailed with the threat of their sons' expulsion and forced into submission. The plot is almost identical for everyone, moving along quickly at about 20 minutes per person. Not everyone is a beauty, and some actresses don't exactly have great figures, but that actually adds to the realism. Watching these mothers sacrifice their bodies for their sons was quite a turn-on. However, I'm dissatisfied that everyone ends up only half-undressed. These women barely resist and are completely submissive, so why not have them go fully nude? I deducted one point for this.
