Your Step-Mommy Sydney Screams has just come into your room carrying an arm full of snacks for you. Always the attentive feeder, Sydney baked some brownie bites for you to eat along with lots of junk food. They can't keep their hands off your belly and confesses that you're actually their favorite of all of your step-siblings. You listen to step-mommy and have grown a big belly just like they wanted! Your belly has gotten so big that step-mommy even wants to kiss it with their pink lipstick kisses.
Some weeks have passed and step-mommy comes back into your room to see how big your belly has grown. It's so much bigger!! You're almost completely immobilized. Step-mommy rubs your belly then plants some red lipstick kiss marks on your gut and tells you how good you are. What would you like for dinner tonight? Step-mommy is happy to cook for you or order some delivery or even go pick something up from a drive-thru.
Sydney is so impressed by your growth, but is worried that you haven't been able to cum recently. When you tell Sydney that you can't even reach your own dick anymore, they strip out of their satin blouse and start giving you a blowjob. Once you're nice and hard, Sydney grabs a big dildo from behind them and slides it into your hole, fucking you with the dildo until you finally get a sweet release. Cum for step-mommy! Step-mommy plants a few more red lipstick kisses on your belly and licks your navel before they go to get dinner ready for you!
