With an overwhelming healing aura and cute looks, Hanakari-san is popular among the male students. Today, the students are doing a practical emergency rescue exercise while completely naked. It's a practical exercise where every second counts, so they have to take it seriously! A male student is intentionally touching her nipples during a cardiac massage, and his tongue is inserted mouth-to-mouth, but she shouldn't be worried about that! Her perfectly shaped breasts are a sight to behold. Her nipples are pointy. She's sensitive and twitches, but she endures it with all her might! Next up is a condom clinical trial. If she cooperates enthusiastically, her grades will go up. She even gets an allowance. Don't look away, Hanakari-san. After she gives you a blowjob, she'll take it in her mouth! Hey~ (lol) If I make him ejaculate here, it won't be a clinical trial~ (lol) The student's huge dick goes in. How does it fit? "It's rough." Hanakari-san, relax your legs. Does it hurt? Is it uncomfortable? "It doesn't hurt. Ah◆It's fine..." Not just "it's fine," but more specifically? "Ah, ahh... it hurts." How is it different from the ones you normally use? "It feels like rubber. It's better than the three I've used so far..." The student thrusts it in vigorously to test its durability as well! This is a clinical trial, so please refrain from moaning. Concentrate! When I do a reverse cowgirl, my clitoris gets bigger and the students stare at it. What's that smell? Is it a contraceptive? Is it Hanakari-san's? I can't stop pounding her (lol). Her expression turns seductive, and her secret garden gets incredibly wet! Her round ass is incredibly sexy. I want to squeeze it! If you gently stimulate her clitoris, she will squirt with pleasure. She takes off her nurse uniform, convulses when you insert it from behind, and cums inside the condom! The rubber is extremely durable! It was a good clinical trial!
