How Do You Know If It Worked?

A girl raises her hand, Cady, "How do you know if it worked? I mean, how do you know if she's pregnant?"

"An excellent question." You say as you pull out your still stiff cock, dripping cum and juices all over the lab table. "We will not know for sure for a couple of days at least, but we can certainly help things along."

"How?" Lisa asks.

"I need two volunteers..." The girl's hands all shoot up quickly. "Lisa... and Lauren. Step up." Lisa is a tall and thin blonde with long legs and a small chest. Lauren is a perky petite brunette with freckles and a sizable chest. "Lisa, have you ever practiced cunnilingus?" She blushes and nods. "What I would like you to do is help Mona to another orgasm."

"But," Lisa questions, "Her pussy is filled with cum."

"Yes, the cum that spills out is semen that did not reach Mona's womb. Feel free to swallow any of that as you lick her. Meanwhile, Lauren... if you wouldn't mind applying your lips mouth and tongue to my member, we can reapply our procedure."

Lauren gets on her knees and eagerly takes your cock into her experienced mouth. The other girls look upset as they can only watch and touch themselves.

"You can all provide sexual stimulus for us by stimulating yourselves. The pheromones you give off will make our bodies react more quickly." The room descends into an almost exclusively lesbian orgy and your cock stiffens. Lauren seems intent on finishing you herself, but Mona's own cries indicate she is more than ready for another demonstration.
