As promised, Journal Entry 232 / 6119: Sterlings: Polly and Saul has been posted to the website.
I will say that this is one of my favorite stories in the Sterlings arc. The sex is pretty good, for one thing. But as a piece of fiction, Polly and Saul has some of the best lines I've written in a long time. The dialogue between the two of them is wonderful stuff, gendermangling and giggly all at the same time.
It's almost a pity Saul doesn't show up a whole lot more in the series: He appears again in Provocation and Midpoint, both of which show different sides of him and his relationship to the futanari Sterlings he's interested in.
Story codes for them that care: [M human / futanari human, oral, anal, slow]
