Grinning into Ms. Young's face, you continue to thrust your throbbing cock deep inside her pussy. She gasps at the deep penetration, feeling your cock growing thicker, and pulsing as you approach orgasm.
"As I was saying," she says, looking at you sharply, "When the male withdraws....."
Your hands pull her hips against you, and you push into her as deeply as possible. Her pussy squeezes you, and you feel your balls tightening.
"Hello?" She groans, pushing at your hips, trying to extract your cock from her soaked pussy. The wet noises it makes as you squish in and out of her excite you even more, and you pull her against you, feeling the come starting to rush up your shaft.
"Well, class" she throws back her head, feeling your cock starting to twitch inside her. "Here you see the tendency of the male to attempt to fertilize the female despite her protests."
You pull her against you as your cock begins to jet sperm deep inside. You pulse inside her, coming hard against her, as her pussy contracts and expands with your thrusts, pulling every drop of seed from your balls.
"At this point," Ms. Young explains to the class over your shoulder as she continues to fuck you through your orgasm, "The male's sperm will travel through the uterus and up the fallopian tubes. There it will attempt to find an egg and fertilize it. Fortunately for me, I am currently on birth control pills, and so will not be impregnated."
You blanch at her statement, looking into her eyes. She smirks at you, and rolls her hips against your cock, which begins to shrink inside her.
"Now then," Ms. Young finishes her comments with a flair, "When the male withdraws you will see the sperm that he has injected into me. I would like a volunteer to take a look at it, and tell me what you think."
You pull your cock from Ms. Young's pussy, and a small flow of sperm oozes out of her. Many of the girls in the class are looking on with considerable interest, and several have raised their hands. |
