New teacher Slender beauty Ms. Tanihara. Today is a sex education class for diligent students, and she's a bit nervous... 'Huh? Kondou's girlfriend? To meet you here!' What?! The school doctor is her fiancé's best friend! Even more embarrassing (laughs) But still, she measures the students' erections with a smile. 'What? Me too...' and has her clothes and pure white underwear removed by the school doctor, starting the examination. 'Everyone, watch and remember well~' As the school doctor measures her vaginal diameter and depth, she's already overwhelmed with shame... 'Huh? Huh? I've never heard of practical sex techniques for determining male or female!' Mr. Tanaka's soft touch causes her nipples to reflexively erect! Doing foreplay thickly and intensely makes it easier to give birth to a boy! For girls, it should be lightly! 'Ms. Tanihara, is this thick?' and she's given a deep throat. 'Ahh, I don't know...' 'It's embarrassing if you can't properly teach the students. Alright, let's do practical training for determining female birth.' The school doctor's huge cock invades, 'It's better than his...' feeling incredible in various positions! 'No good. You shouldn't feel anything when determining a girl. Do it properly!' 'I'm not feeling anything...' 'That's how you feel when determining a boy (laughs)' Thrust hard by the school doctor and turned into a female beast, cowgirl position pounding piston! Surrounded by students, having her breasts squeezed and nipples tormented at the same time, she arches her back and cums! 'How many orgasms do you need to be satisfied? Please stop!' While sucking a young and potent student's cock, she has semen blasted deep into her vagina! Ms. Tanihara, this is how you make a boy (laughs). But the students learned a lot. Thank you!
