You're mommy's handsome firstborn son, and nobody could ever replace you. But now that you're grown up, your mommy is lonely. Having had you so young, your father and I are finally ready to get pregnant again, with experience on our side this time. There's just one problem son- he's shooting blanks and YOU are the only man for the job, the only one who looks enough like your father to pull this off. Oh, fuck. I had assumed that you would have a much bigger cock- it's so tiny that I just don't think it can do the job. But don't worry, mommy always thinks on her feet. Here, swallow this. You're so incredibly tiny and adorable now, sweetheart. And now you have to make mommy proud. Crawl into her womb and cum directly inside of it. Make mommy pregnant. And if you rebel? I'll just shove you up there myself. For Fans of: Taboo Roleplay, Mommy Roleplay, Shrinking Fetish, Giantess Fetish, Unbirthing, Dildo Fucking "Impregnate Your Giantess Mommy" by GirlOnTop880
