This isn't sex! It's a reproductive ability test! Uncooperative students will be placed on the blacklist. The autumn mixed-gender full nude physical evaluation is almost over. Girls must face the boys and measure their erect penis growth. Skillfully jerk them off to assist ejaculation. Failure to participate seriously will negatively affect every student's academic recommendation. A vaginal pressure competition is also held in a girls-vs-girls format. Each pair inserts a connected measuring device into each other's vaginas and compete in a tug-of-war. The winners receive more recommendation slots. Ready, go! Open your legs wider. Everyone gather close and cheer. Pull harder! Focus on your vaginal pressure! You've all worked incredibly hard. The Board of Education sincerely appreciates your cooperation. Finally, the female reproductive examination. A student volunteer will substitute for the teacher (laughs). From behind, nipple pinching, cunnilingus, gaping manual fingering—she's highly skilled at preparing the female genitals. She takes the teacher's huge cock into her mouth and gives a titty fuck. Good job—here's a reward for your effort and pleasure... "Huh? What? Something from behind... ahh!" You like it when it's slowly squished here, don't you? "That's not unpleasant... Teacher, that's not unpleasant... May I be happy?" Doggystyle, rolling thrusts, spanking. Boys and girls face each other while being pleasured from behind in standing rear entry! Reverse cowgirl, cowgirl, counting the number of hip thrusts. More than before! That's it, that's it, your grinding hips are perfect! How does this position feel? "This isn't bad..." You're feeling ecstasy! "Men feel ecstasy too?" As she moans, student and teacher cum is blasted in huge amounts straight into her mouth! Great job, everyone! The Board of Education will increase this school's recommendation quota! Give a round of applause for all your hard work!
