Today's home economics class is about guidance on sexual behavior to combat the declining birthrate. It's the aspiration of the male students. Let's learn about proper sexual negotiations with the class president, "Ichiishi-san"! "Eh? Maybe I misheard... but are we talking about sexual behavior?" Ichiishi-san is confused. Will skipping this class affect my grades? Will taking it seriously be beneficial for my future studies? It's embarrassing, but I really want to advance... Being forced to confess my sexual experiences is humiliating. Hugging, kissing, and caressing the genitals with lower-caste boys. "If I can be of help to everyone... I'll do my best in bed..." Stripping each other, licking nipples, studying changes in voice and body. Checking for sexually transmitted diseases, the smell of puberty dirt accumulated on male and female genitals. Drinking sperm can also deepen affection... If it's not with someone I like, I wouldn't want this! Even though I want to say it, the humiliation of fellatio leads to an inevitable ejaculation for the male students. When the teacher pushes the penis deeply into the vagina, "Eh? With the teacher?" "First, does it fit at the tip?" "The intense part comes later?" "It's pushed quite deep and it feels good... but it's embarrassing..." Sometimes instruments are used when seeking stimulation! Stimulated with an electric massager, thrust with a devilish dildo! Ichiishi-san is on top? Likes this angle of doggy style? Enjoys the riding position, huh (laughs) pointed out by the doctor, the embarrassment reaches its peak, hips accelerate, and moans echo! The class president, climaxing in front of classmates, ejaculates vigorously into the condom! Trembling in the afterglow. Sniffing the condom, "It smells like you worked hard..." "There was a thud during ejaculation," explaining while looking down, it's easy to understand! As expected of the class president! I learned a lot!
