"Aletha (Granny's New Hobby)" goes straight through start to finish and is very nicely dirty along the way with a twist at the end. You'll need a towel, if not a hot shower, after reading. That's a plus, in my view.
Serena sends her greetings to the group. If you haven't read her stuff you're in for a treat. She's got an epic (Davidson Fisheries and McElroy Family) and any number of shorter reads. Highly recommended.
