Daffy Yum - Day 20 Jumping Harlequins
I like Robbins attention to detail here, "Mr. Hankshaw looked from his wife to the doctor to his high-top Red Wing work shoes (in which stolen laces had been recently replace)..."--referring to the Hankshaw boys' attempts to lengthen their thumbs a few pages earlier.
I bet that if Sissy's big thumbs were just a little more common there would be an internet newsgroup called alt.erotica.women.thumbs.big.big.big. But I guess there is in a way. The aftrlife is a website, two discussion groups and a blog dedicated to any and all Robbins-created exotic erotica.
