Yes

"Yes Ms. A" you say and begin to remove your clothing. When you remove your shirt all the girls look at you appreciatively and when you remove you pants and underwear to reveal your hard-on they all gasp. Even Ms. A looks impressed.

"Thankfully our friend here is a fine example of manhood." Says the teacher. "As we can see from his engorged penis he is ready to engage in the reproductive act."

One of the girls raise her hand and asks "Can we touch it?"

"Perhaps if he's willing, he might let us examine it more closely later." Says Ms A. "But for the moment it will be too busy. Now as I described before the female's vagina is now lubricated. This is to ease the insertion of the penis. Without this, or some other lubrication, the sex act can be painful for the female. Remember this girls and try to convince any sexual partners you may have to stimulate you to at least one orgasm before insertion so that you are properly lubricated. Now Virginia, are you ready for him to insert himself into you?"

"Yes" whispers Virginia.

"Is your hymen intact dear?" asks Ms A.

"No. I …"

"It doesn't matter ... however were is still intact the male would need to **** his way past it and in doing so would cause it to tear. Because of this the first sexual act is usually painful for a female and there is some bleeding. Now if you would be so kind as to begin" Ms. A says looking at you.

You walk over and position yourself between Virginia's legs. She looks up at you and smiles. You realize that she is turned on in equal parts by the idea of having you inside her, the fact that she is were every other girl in the class wishes they were and the fact that all her peers are watching her take you into her. You put your cock at her opening and she bites her lip a little, preparing for you.

"The sexual act proper begins when the male inserts his penis into the female's vagina" says Ms. A and you follow her description by doing just that. Virginia groans as you fill her, her tight pussy squeezing your entire length.

"The male then moves his penis in and out of the female vagina, increasing stimulation for both. The female can squeeze her vaginal muscles to increase this stimulation further." You both follow Ms. A's dialogue.

"Unlike the male, who requires usually a long period of respite between orgasms to regain his strength, the female is able to achieve multiple orgasms during the sex act, as I believe Virginia is, once again about to, is this correct?"

"YES" cries Virginia as her pussy spasms around your cock "OH GOD YES"

You can feel your cum boiling up from your balls.

"Usually the male would release his ejaculation inside the female's vagina, but if you could withdraw before you do so" Ms. A says to you "we will be able to see how the ejaculate is discharged from the penis."

You pull out just in time and spray your jism on Virginia's stomach.

"Good" says Ms. A. "So now we have all witnessed the sexual act. Now we still have some time in this lesson so I might move onto masturbation" you hear the girls groan disappointedly "unless our friend here is willing to let some of the other students examine his penis and possibly practice stimulating it to an erect state. Then maybe, if we have time, we can examine the merits of various sexual positions. Of course only if he's willing."

All the girls look at you expectantly.
