New men’s-esthetic girls join a course to learn service skills that can win them No.1 nominations. The charisma instructor is actually a perverted lesbian. She exploits their ambition: oil-soaked practical guidance pulls them into lesbian play, skilled technique hammers their climax spots, then under the name of “back-option training” she takes them into strap-on real sex. Violent pistons make lesbian squirting that will not stop.
