I can't say enough about how big of a fan of Chirenon's work over at Male Protection. The amount of effort he puts into his captions and stories is obvious, and I love the way his mind works. So I guess that's where this one came from.
I've always thought Phalliminate would fit quite well within one of my gender role reversal worlds. It doesn't feminize a man by itself, but getting that penis size under control goes a long way, I think. And you all know how much I love making advertisements!
