Some expiraments... (testing limitations)

You need to know exactly what this can do, and the rules don't help much. So you write a few things:

Melissa Bolt will kiss her hand, but this excludes Melissa Bolt. Then ten seconds later, Melissa Bolt will touch Sarah Bolt's ass in three seconds. then shout "Ello!".

You then release a loud and lusty moan as your love juices uncontrollably soak your pants. After ten seconds you begin to uncontrollably sprint halfway up the stairs until you let out another loud and lusty moan as your love juices soak your pants once more and just as intense as the first time.

You expected to run up the stairs, but didn't expect the default situation to come into play.

The first statement has a logical contradiction, so as it immediately fell apart, the impossible situation was then replaced with the default situation of profusely cumming on the spot.

The second statement can be performed, but your sister Sarah is halfway across town, so it did not happen, although you certainly tried. You have learned that semi-possible situations will be attempted even if the person doesn't want to do it. However, once any one detail of a situation falls apart and becomes impossible, that situation will be fully replaced with the default one.

You return to your room and change your pants... and panties.
