He Sticks Around A While

John let his Aunt blow up as he headed to the bathroom. He thought about how big she'd get, how she was carrying his children. After reliving himself he headed back down to an awe inspiring sight. There was his little Aunt Jessica, sat on the floor with her yoga ball tits leaking milk and a perfectly round stomach which was about the size of a car. "My, my! They're growing big just like daddy!" He grins as he runs his hand along the curve of her belly before kissing it gently.

"H..h..how many are inside m..me?" The woman asks, looking slightly frightened of the mass of babies growing inside her.

"Oooo I'd say at least 30 of my kids are in your womb Aunt Jessica. Blowing you up like a big balloon. Soon enough you're gonna pop and make me father to a happy little family." Another devilish grin crosses his face.

"You're sick! I'm going to give birth to your children and you won't even help!" She growls at the man who made her like this.

"That's quite the assumption! And quite rude as well! I'm going to love and care for my babies like any good father would. I'll even do diaper duty. And once I'm done with my other cows we can all live together like a big family. Don't you agree my little moo cow" He smiles before clicking his fingers. Small horns start to grow from her head and a tail snakes out from her back.

"Mooooo! Yes master... all your babies in one happy family" Jessica smiles sweetly. John had changed her mind as well as her body. He couldn't have her being a bad mother to his children. Her stomach swells again getting close to the ceiling before her waters break.

With another click a team of midwives appear to tend to the gargantuan woman and her oncoming brood. "As soon as I'm done with my other cows I'll come to see our children my sweet" He blows a kiss before going to leave. After a few moans and groans from behind he hears the cry of his firstborn before leaving through the door. There will be plenty of time for that later.
