Alien Impregnation Fantasy. 29 weeks Pregnant

Scenario: I'm a single pregnant woman, getting pleasured by some random guy I met online. I'm riding him (pov cowgirl) like crazy until I starting to feel his creampie inside my belly. I rub my belly and dirty talk about how much I love being pregnant and all the movement I feel inside my belly. Next scene I wake up and start to reminisce about last night, and how good my date was and how I wish he could be my baby daddy. Suddenly I start to get belly cramps, and then become shocked at how much movement I feel in my belly now and wonder if I'm carrying twins. Then I go to the bathroom to get a better look at my belly, until suddenly I start to feel kicks inside and begin to massage my belly to help ease my "braxton hicks." Then I oil my belly and breasts while I talk about how much movement I'm feeling inside and how it's starting to hurt. I then start say that I'm feeling a lot of movement in my belly and my belly then pulls me around until I stand in front of a window. then I compelled to get on my knees as my belly begins to push in and out to immense pain and horror. I feel like something is trying to burst out of my belly as I'm paralyzed in front of the window while my belly moves like crazy until my belly pushes out to its maximum where I then scream and pass out.
