"Do you always wear such sexy underwear..." Ms. Kanna, a new female teacher, came to a boys' school for sex education training. In order to accurately measure the students' physical development, the teacher is asked to take off her clothes. Short bob, big breasts wrapped in a pink bra. Beautiful nipples are visible through the material. Come on, make eye contact and measure the student's erection! (lol). "Teacher, this is not your first time to squeeze an erection, right?" When the student palpates the inside of her vagina, it is already wet and soft (lol). Ah, it's quite sensitive. Maybe it got wet when you squeezed his penis? Finally, this is a practical sex course to learn about gender selection, plan your life plan with your future partner, and promote a deeper understanding of vaginal ejaculation. When the teacher refuses, saying, "Um, that's a bit much...", the male teacher says, "All the interns have done it before!" and "Just leave it to me, I'll teach you!", and says, "Everyone! Watch, watch!" as he holds out his dick, and the male students go wild with the unexpected deep throat and 69 (lol). "Everyone watch. At first, I put it in normally, but... when I put it shallow, the girl... ah, ahhh!" "On the other hand, if I put it in deep like this, the boy... ahh, ahhh..."Kanna sensei forgets about her lesson and feels so much as the male teacher thrusts hard! When asked "Do you prefer boys or girls?" she replied "I want it deep inside..." as if to satisfy her sexual desire. They let their sexual desires collide, and the male teacher ejaculates a huge amount of sperm deep inside her uterus. "They say it's easier to have a boy if you orgasm and cum deep inside..." he explained to his student in a daze, showing his teacher spirit. Thank you, Kanna-sensei!
