Yes

Jessica shakes as she tries to physically contain herself but your finger gives a last flick and she cries out in a deep loud moan. Everyone looks over, though seconds later Virginia too cries out as Mrs. A has stimulated her own orgasm.

"Well now... seems we have some students looking for extra credit. Both of you, clothes off." You and Jess strip down. Your cock is stiff and throbbing having been stimulated for so long. "Before we continue I'll have to check if the girls are ovulating."

Mrs. A presses against the abdomens of both Jess and Virginia. Her expression is hard to read. "It seems that you are both ovulating currently. If you were in this state to have un-protected sex, procreation is likely. It is likely that most of the girls in the school are ovulating, as groups of women tend to synchronize."

Your face goes pale. You are fairly sure that means that you are expecting with one or two girls now. Mrs. A doesn't seem to notice. "Since this is biology I have no problems thoroughly exploring re-production." You are shocked.
