A Southern States sport that seems to be going viral,
they call it noodling - we Scots call it guddlin
the Urban DIctionary has another sense for guddling,
To insert one's finger(s) into a woman's vagina to pleasure her digitally, while simultaneously having penile-vaginal intercourse with her. (From the Scottish term used to describe the catching of a fish with one's hands by tickling it on its underbelly before snatching it out of the water.)
As used in Diana Gabaldon's novel, _An Echo in the Bone_: "He pulled out the finger (from her anus) and guddled her, light and quick, all along the slick deep parts, feeling his own cock under his fingers, big and slippery, stretching her..."
I love the look on her face. I wonder if her tickling skills translate to the bedroom?
