High school teacher Naoko Tsuji goes rogue to give her students the best, most informative, and most sex positive sexual education class she can. She has a tendency to sexually harass the school nurse, but her lessons are humorous and educational with a strong yuri bent, and they should be welcome and reassuring to any teen who picks up the book. (Ironically, the book is for "mature" audiences with a parental advisory warning. Watch out for those corrupting sugar glider and elephant penises!) ( )
