Later that night, Jon had masturbated and had some of his semen available, so he considered experimenting with the ring. There were two problems. First, pregnancies were permanent. He supposed he could wish the offspring to some dimension which needs people, or send it to the future, or something like that, to solve the problem if things really got bad.
The other problem was that most of the choices he could use it on were bad. His room was full of objects, but having a child who's half Jon and half DVD, or half homework assignment, or half gum wrapper, wasn't even a perverted fantasy; it was just stupid.
But what could he use that would make sense?
