It all started with a blinding flash of light as I was walking home from the book store. There was nothing but white. Even closing my eyes did not stop the white light.. Time got away from me, because the next thing I know, I am strapped to a table, my hands and legs restrained. Inside of me I can feel something hard vibrating inside of me, something like a glass tube inside of my cunt. As confused and afraid as I am, I am also feeling very wet and horny. I grind against it , getting closer and closer to orgasm. Finally I cum screaming, and as I do this tube "cums" inside me too, filling me with a liquid that feels thick and heavy. My stomach is a little distended, and a robotic arm shoves a thick vibrating dildo inside of me on the lowest setting, to keep the liquid inside of me.
I hear a deep, not quite human voice that talks to me.
"Greeting human female. We are the Ginari. You and four others have been chosen for a very important purpose. You are the closest species to us in terms of mating, and a tragedy on our planet has depleted our species. That being said we have decided to...how you say...improve you. As your impregnation cycle is long, inefficient, painful and deadly, we have decided to upgrade you. We have pumped you full of our sperm plus a liquid that will speed up the pregnancy and birthing process as well as make it quite pleasant. You are currently carrying twins, although if this experiment succeeds we may make it so that your body carries more if you wish to stay. Every time you orgasm you will go through one month of pregnancy. At the end you will have a painless orgasmic birth. You may orgasm with toys, with each other, or with us. We will make sure you are well fed and taken care of. Any questions?"
