"Now class today we are going to begin our sex education lesson," said Mrs. Winters, the very attractive sex education teacher.
"Now before you joined this class you were required to sign a form that doesn't allow you to tell anyone what happens in this class. So has everyone brought in their signed forms to class today?" asked Mr. Winters the other sex ed teacher and the husband of Mrs. Winters.
All the students nodded their heads to show that they had turned in their forms. "Well that's good" said Mrs. Winters, "now the reason we asked you to get those forms signed is because this is to prove that you have passed your eighteenth birthday and because this is going to be a very different kind of sex education class from the kinds of classes you have been in before."
"Now we want you all to be very comfortable with your sexuality and we feel that the best way for all of you to do this is with full participation in the class," said Mr. Winters.
"In order for everyone to fully participate we are going to require everyone in the class to remain naked at all times while you are in this classroom," Mrs. Winters told the students.
The class all began to talk at once protesting the fact that they were going to have to be naked in class. "Now calm down class I know all of you may be uncomfortable with being naked in front of your fellow classmates, but believe me this will help you become more comfortable with your sexuality," said Mr. Winters "and to make all of you feel more comfortable Mrs. Winters and I will also be staying naked for the duration of the class also." With that both Mr. and Mrs. Winters began taking off all of their clothes. Once they had finished undressing they stood before the class completely naked and needless to say every eye in the classroom was focused on the two naked teachers in front of them, or at least on certain parts of them. Every male student's eyes were focused on Mrs. Winters' large 36DD breasts, while all of the female students were focused on Mr. Winters' large penis hanging between his legs which was about seven inches long even in its flaccid state.
"Now as you can see we are perfectly comfortable with our nudity and we want you to be as comfortable with your nudity as we are with ours," Mrs. Winters told the students.
"Now get those clothes off. Come on lets get a move on," Mr. Winters ordered the students. This was quickly followed by all of the students beginning to remove all of their clothing. Some of the students struggled with taking off their clothes because they continued to pay attention to their naked teachers at the front of the classroom. Eventually all of the students were naked in the classroom, most of the students were shyly covering their genitals.
"All right now that all of you are naked we are going to go over the first thing that happens to begin the sexual cycle; arousal," said Mr. Winters.
"Who can tell me what the signs of arousal are in a man?" Mrs. Winters asked the class. Devon, a slightly nerdy looking student raised his hand and started to reveal what looked like an impressive erection he was trying to hide under his hand.
"Yes Devon?" Mrs. Winters said.
"Well the most obvious signs of arousal in a man is that his penis will become hard and erect, which is known as an erection," said Devon "another sign of arousal in a man is that his testicles will swell as they prepare to release semen."
"Yes, that is correct Devon." Said Mrs. Winters "Now there are many different ways to get a man aroused and cause him to have an erection. The first and most obvious way, which I'm sure many of you young men are experiencing, is seeing a naked woman. I'm sure that since I took off my clothes many of you began to have an erection, which was only increased when your fellow female classmates also took off their clothes so you should not be ashamed about having an erection right now."
"As you can see I am also beginning to produce an erection from seeing my wife and all these lovely young ladies naked," said Mr. Winters, which prompted many of the female students to look at his hardening penis, which was now pointed almost straight out and had increased in both length and thickness.
"We will discuss other ways you can cause arousal but for now could someone tell me about what arousal looks like for a woman," Mr. Winters asked. Michelle, a brunette girl of average height raised her right hand, while she continued to use her left hand to try and cover her full C-cup breasts.
"Yes Michelle," said Mr. Winters.
"Well when a women gets aroused her nipples get hard and erect, and sometimes her breasts swell so that they appear fuller and her vagina begins to get wet," Michelle said nervously.
