I am a sexy big butt scientist, and today you’ll be my ASSisant! We are going to do an experiment. The experiment is a “cum combination.” By combining the DNA in my “activated” shit with your cum, we’re going to fertilize my shit–and make my shit pregnant! My butt is so full of shit and have been holding it in. I twerk to shake up and “activate” my shit before unloading it onto a plate. Time for your part! Please, cum all over my shit!! Impregnate my shit babe… for science!
