Sex Devil by Randy Chandler

When Toby Smith locates a legendary sex artifact known as Phallus de Satan, he is eager to share it with erotica writer Dakota Kennedy. According to esoteric lore, when a couple makes love while the man dons the "devil's dick," they are joined by an invisible devil for a demonic three-way. Dakota accepts his kinky challenge as a lark, but no one is prepared for the shocking sexual violence that follows.

A twisted tale of devilish BDSM.
