The Story This is a impregnation fantasy/rapid pregnancy video. Your student, Josh, and yourself, his professor, have been working late some nights in your chemistry lab. He's been such a great help, and you may have secretly been eyeing him up. After cleaning up some spilled experiments, you catch him looking at your cleavage. After questioning him about it, you decide to tease him, knowing he finds you very attractive and sexy. You two can't deny your bodies' wants, and give in to your instincts. You climb on top and ride him, taking his thick, white cock deep into your pussy until he can't hold back and unloads his cum inside you. You comment on how warm it makes your belly feel, softly rubbing it and then climbing off him. You bid him farewell for the night and will see him tomorrow. The next day, he comes into your office and sits down, ready to do some more work in the lab, when you say that you need to talk about something. (Due to your desk or something in the way, he can't see below your chest) You remind him that you had to clean up some spilled liquids before last night's... Action. At the time, he didn't know you were testing fertility chemicals, and after what occured last night, something happened to you. You assure him, it was a fun and enjoyable time, commenting on how great it felt and the warm feeling in your belly was so amazing at the end. But the warmth has remained, if not gotten hotter. You stand up/reveal your belly is swollen and stretching out your top. You already look several months pregnant, especially when you cradle your belly with your hands. You can't believe this happened, but you're happy to be a mother. You talk about how big and heavy you feel, but how sexy you feel in your newly fertile form. Your breasts feel bigger already, so tender and getting ready to be full of milk. With the potency of the fertility serum that was spilled, you're pretty sure it's twins, with how big and active your belly is already. After you say this, you begin to feel movement and kicks inside you. You ask him to feel and after enjoying this tender moment, you notice he's hard. You like what you see and get him to whip that big white cock out. You want him to jerk off and cum for you and your newly pregnant body, teasing him that he knocked up his professor with twins. Everyone will notice how big, huge, and pregnant you are, and his huge cock and fertile seed are the reason.
