Sexy Erin Shay and irresistible Kale Alexander are working together on an innovative sexual enhancement serum, Pleasure Prolonged. This serum's development is the latest breakthrough for the Iowa Research Center and promises to change the personal lives of everyone who uses it.

Deanne Sinclair, chemist and conspirator, will do whatever it takes to have Kale notice her while experiencing explicit pleasure in defaming Erin at every turn. What Deanne does not anticipate is that her actions will bring Erin and Kale closer together and strengthen their resolve for one another and their project.

This is a refreshing and sexy story. I absolutely, positively love this brilliant and innovative series! The characters are very realistic, the plot is believable and falling in love with Erin and Kale's chemistry is inevitable.
