In "Paying the Forfeit", a brother runs into an interesting situation with his wife and his sister.
The two women are best friends, who love to spring bets on each other, with penalties for the loser. One bet leads to a brush with FF sex, and the next one leads to incest.
This story had a good plot, but really poor writing. Run on sentences are the norm in this story, making it feel like the author is rambling. There are a few spelling errors, but nothing major.
The sex is pretty hot, with good stroke value. With the short nature of the story, if you are looking for a quickie, this one should fit the bill nicely.
This is one of the early Ale Stone works. His more recent writing is much more polished, so don't take the poor writing in this story as how he still writes today. I don't see the author going back and rewriting a nearly 5 year old story, but this one would have benefited from an editor at the time it was written.
If you are looking for stroke and don't care about writing quality, this one is pretty good. If grammar and punctuation errors drive you batty, you may want to stay away.
