Pregnant Biology Teacher Gives Student a Personal Lesson. After being called ‘fat’ by you during class, I ask you stay behind and come to my place for some remedial lessons…Little did you know about how women get pregnant, I elaborate and show you how! I tell you to stroke yourself as I undress myself, explaining how a man pumps his cock into a woman and filling her right up with his seed. Which gives big bellies like mine. I make you get hard first with a little head to help you, and stop just before you cum, that you must cum inside a vagina and not the mouth to impregnate a woman. I just ontop, and rub my belly and moan with you inside. I carry in explaining how your cock is the perfect size to make a woman pregnant. Right until you fill me right up!
