Primal Instincts — Lisa Renee Jones

The search for a rare flower rumored to possess magical aphrodesical powers had led Drs. Olivia Markham and Jordon Brooks into the remote heart of the Mexican jungle. But a mysterious native tribe dedicated to keeping the Estela flower from reaching the outside world required the two stunning scientists to experience its powers firsthand to convince them of its dangers. Paired with two breathtakingly sexy warriors, Olivia and Jordon drink the sweet essence of the Estela and are overwhelmed by lust so intense it nearly consumes them. Their warrior lovers seem to intuit their deepest, most secret desires, and in their experienced hands, their overpowering hunger is satisfied again and again until, at last, the effects of the drug subside.
