You're not sure, better try again!

You grind your hips into Sarah's pelvis, reveling in the sensations that her contracting pussy brings to your cock. Feeling the last drops of your seed spurt into her, you pull back, and your cock comes free with a squishing noise. Ms. Young releases Sarah's hands, and the girl, rapidly hops off the desk.

Sarah takes several steps, before her knees buckle and she slips to the floor. The nearly naked girl's head is spinning from the sex and can't walk straight.

"As you can see, class," Ms. Young continues her lecture, uncaring of Sarah, "Sexual intercourse can often cause a loss of equilibrium in the female."

Sarah collects herself, and begins to slowly dress again. You are amazed at the girl, who not five minutes ago was fucking you, as she quietly goes about her business. She finishes redressing, and returns to her seat. You notice her touching her stomach occasionally, and you wonder if you indeed did knock her up. The though brings more blood to your cock, and you soon find yourself hard again, with a room of women staring at you.

"Now then class," Ms. Young continues, "How many women can be impregnated by a male in a single sexual session?"

Many hands are raised, and Ms. young pauses before selecting a cute little blonde in the front row.

"Amanda, yes?" Ms. young calls on the girl.

"One?" answers the girl, and you think how much you'd love to show her if she was right....

"No. And because of your incorrect answer, you and two of your classmates will demonstrate the correct answer. Come up here."

Amanda bites her lip in confusion, but stands, and with a backward glance at Sarah, moves to the front of the class.

"I need two more volunteeers, or I pick you." Ms young announces to the rest of the class.
