The Gratification Engine: An Anda Barrows and Allis Obby Story (An Intimate History of the Greater Kingdom)

Highcock's Oscillating Apparatus has harnessed steam to cure everything from hearing loss to "female complaints." That's what two Scholar-Priests of the god Eddin hope. The old lechers also hope to watch black-haired beauty Allis and lusciously plump Anda--two priestesses of Neya the Beloved--try its vibratory motion on one another. But Allis and Anda choose young Scholar Jep Burman to assist in the experiment instead, to give him a sexual education he'll never forget.
