Now being sceptical of the app, you were slightly hesitant to actually try the app out. If it worked, the whole universe was your sandbox. If not, then the app could be malware that got onto your phone.
In a brief sense of hope and worry, you started to type away in the app. It wasn't going to be anything big, but still noticeable that you would notice straight away.
'Human men can never relieve their bones once they turn 13' and 'Human men feel no shame when they get a tent in their pants' were two rules you changed.
Almost immediately did you start to feel a pressure in your groin signalling that you had gotten a boner. Looking down, you could certainly tell you had one, but your jeans seemed to have a large pouch in the crotch area. You were unsure of why your Jean's had this pouch until a set of memories were planted in your mind, telling you it was a cock pouch. A pouch to hold penises if the clothes are to tight.
Thinking how the app did this minor world change, you were more so scared at the possibility that you were given just from a small app on your phone.
Thinking of what next you wanted to try, you thought of how an even more massive rule change would affect the world. Knowing how the infinite boner rule affected you and other men, how about something to affect the whole of humanity.
With many possibilities, you could easily rule to world or make the world like one out of a fantasy. Maybe make the world into a giant porno or make public indecency normal. What could go wrong.
