Your stepmother is pregnant and having terrible morning sickness. She can't eat anything and is worried about her health. One day, she accidentally walks in on you masturbating. She tries to act normal later, but she is feeling strange... When she goes to change your sheets, she finds boxers full of cum. She tries to deny it, but her desire to lick the cum takes over her... Throughout the day she fights against the cravings, but finally reveals to you her odd desire. After an awkward conversation, you agree to give her some to make sure this is what she wants, and she tastes it from a glass, then gulps it all down, wanting more. She gives you a sacred amulet, centuries old, that is believed to increase fertility, and cum... Then soon begins begging for more, as she is starving. Finally she convinces you to let her suck it straight from the source, swallowing enormous amounts of cum. You begin to realize that the amulet is working when your cum won't stop flowing, and she is happy to take it all. Even after her belly mysteriously grows, ripping her clothing and becoming extremely bloated, she continues until she has to beg to stop as she is too full.
