Hikaru is a beautiful instructor at the Perversion Training Education Center. Normally gentle and meticulous in teaching perverted acts, she also has a strict side, thoroughly disciplining those who fail to perform. Come, let Hikaru guide you down the path to perversion! Lesson 1: "Perverted Masturbation." The flexible Hikaru instructs two trainees in stretching exercises, featuring a variety of techniques such as "foot-licking masturbation," where one masturbates while licking her feet, and the perverse, erotic "vibrator-fixed masturbation." Lesson 2: "Crossdressing Training." To teach a failing trainee proper pervert etiquette, Hikaru dresses him as a woman and takes him for a walk in the park, cultivating his sense of shame and perverted sensitivity along the way. Lesson 3: "Flexible Sex." Hikaru shares passionate kisses, blowjobs, and sex with a top-performing trainee, showcasing her extreme flexibility—her wide-split sex positions deliver shockingly pornographic visuals. Lesson 4: "Perverted Crossdressing Fuck." Hikaru has sex with a feminized perverted man. As their arousal peaks, an abnormal, erotic crossdressing lesbian fuck unfolds between them. Your journey into perversion begins here!
