Josh makes some body modifications to Sarah

As Josh enters the bathroom he starts thinking of what all the phone app can do. He decides to look at the Enter new rule on himself.

"After all, I have changed the entire world, let's see if I can make some smaller changes." He laughs to himself and types

Josh West's penis is 12 inches long.

There was a flash of light and he watched as his jeans turned into sweat pants with an obvious bulge in it. Excited he pulls his sweatpants off and sees his glorious 12 inch long dick. Wow what it would feel like to bury this foot long into Sarah's ass. Wait, if he could alter himself, could he alter his girlfriend as well!

Looking at himself he types in his new rule.

Josh West's girlfriend's ass grows during anal intercourse.

He hit enter and everything changes. The door grew to over 4 feet wide and the toilet was built to seat a rhino. He opened the door and saw Sarah sitting on a couch sized ass.

"Mmmmm You know I'm kinda getting horny again." She said.

Of course he failed to realize that they had been having sex since they had been dating as a senior in high school. Her ass would have grown all those times. As hot as this was, it could have been debilitating so he slammed the door shut and quickly fixed his rule.
