Aoi-sensei is a beautiful Japanese woman with short black hair who is irresistible to those who like slender bodies. Today is a sex education practical training at a boys' school. First, Aoi-sensei will perform an accurate erectile dysfunction test. During the test, Aoi-sensei's breath touches the students' penises, causing them to get full erections one after another! "Teacher, please look at my penis properly! "It's a tradition at our school!" Next is a vaginal examination. Ao-sensei can't resist the calls of the students to show their vaginas. It's true that the thinner you are, the more sensitive you are (lol). Slosh, slosh. There's a lot of secretion, so it's educational (lol). Finally, a successful practical exercise to learn about gender selection. Are your nipples an erogenous zone, Ao-sensei? The overly sensitive new teacher is made to get on all fours, and the male teacher tells her, "Okay, if you want to give birth to a boy, you'll have to hold off on ejaculation for five days," and "If you want a girl, you'll have to ejaculate once a week," before thrusting his massive cock deep into her. "Insert it deep enough to reach the uterus and let it implant!" Ao-sensei can't resist the stimulation deep inside her uterus, moaning and groaning. "Doggy style! "This is the way to stimulate a boy to give birth," "I can feel it even if I move slowly," says Ao-sensei, who wants to cum quickly, and is made to writhe in agony with his piston-like movements! "Please... go hard and deep," she begs, but the pistons are shallow and slow, so she mounts him and counterattacks with a cowgirl piston! The Japanese beauty is driven wild by the pleasure of being spanked on the ass and having her nipples played with by the students. She also gives the students a titty-fuck service that is not part of the training program, and then they thrust into her hard, releasing a huge load of thick young semen into her! This concludes the pregnancy sex practical training! Thank you, Ao Sensei!
