You know your purpose sissy... your purpose is to be a breeder, a bloated, immobile slut. I am your Doctor and I can see by how loose and juicy your sissy pussy is that you have been getting a lot of cock already... but the cock has not been big enough or deep enough to get that belly pregnant. So I am going to make your pregnant myself with my jumbo medical cock. I am going to fuck you nice and deep to fill you up with cum.
