1. I like the story. I think Jon should differently feed Cindy more cum. Maybe have Jon trick and shrink a lot more women and have them be his sex pets. Maybe one of the women are lesbian or bisexual and doesn't shrink as much as the others and rapes them. Maybe some of them actually like serving the dominant bi chick. Maybe every chick around Jon gets shrunk because they love it and want to because it makes every man's dick look and feel a lot bigger inside them. Maybe Jon drinks his own cum. Maybe he discovers that it affects men differently than women and maybe he grows into a giant or maybe just his junk grows giant. Maybe some women shrink so small that they disappear from sight. 

I very much tend to abhor the dominant male over female idea.... but that said, the story was very well written and unexpectedly erotic for me. Thank you for surprising me, and I'm curious to see where you take it.
