Today's home economics class is about sexual intercourse as a measure to combat the declining birthrate. It's the envy of all the male students. Let's learn about proper sexual intercourse with the class representative, "Ichii-san"! "Eh? I might have misheard, but... did you mean sexual intercourse?" Ichii-san is confused. Will not attending class affect my grades? Will taking the exam seriously help me to get into college? It's embarrassing, but I want to get into college properly... The shame of being forced to confess my sexual experience. Hugging, kissing, and caressing genitals with a boy from a lower caste. "If I can be of use to everyone... I'll do my best in bed..." They undress each other, lick each other's nipples, and study the changes in their voices and bodies. They check for sexually transmitted diseases and the smell of male and female genitals that have accumulated smegma during puberty. Drinking semen can deepen love... I don't want to do this unless it's with someone I love! A male student who wanted to say this but couldn't help but ejaculate during a humiliating blowjob. When the teacher inserted his penis deep into the opening of her vagina, she said, "Eh? With a teacher?" "First, do you get used to the tip?" "The intense part will come later?" "It feels so good to be thrust so deep... I'm embarrassed..." When she wants stimulation, she sometimes uses tools! She is made to climax with a vibrator and her G-spot is pounded with a hard piston! Is Ichii-san on top? Do you like this angle from behind? When the doctor pointed out that she likes cowgirl position (lol), her embarrassment exceeded the maximum, her hips started shaking faster, and she started moaning loudly! The class representative orgasms in front of her classmates, and she ejaculates into the condom! She twitches in the afterglow. She sniffs the condom and explains, "It smells like you've worked hard..." and "It was a big squirt when I ejaculated," while looking down. Her explanation is easy to understand! As expected from the class representative! I learned a lot!
