His Undercover Virgin by M. Never

Sorority Secrets: The virgins of Beta Kappa Nu would do anything for each other. Even auction off their most valuable asset…

Officer Eli Kirschner is accustomed to going deep undercover. This time—this job—is different, though. A suspected prostitution ring, with college girls sent off to the highest bidder.
A face like an angel. The thought of someone taking advantage of her makes my blood boil.
Eli is blindsided by Ash’s innocent allure. The instant pull she has on him and the way she makes him feel again.

I’ve encountered a lot of women, but none that have affected me on a primal, paramount, primitive level. The desire to protect is immeasurable.
Caught between duty and desire, reality and fiction, Eli continues the ruse as the intensity of his relationship with Ash deepens.
I’m not a wealthy businessman. I’m a cop who barely has two nickels to rub together.
When Ash comes clean about her reasons for auctioning off her virginity, Eli’s decision is made.
I want her in my life, in bed and in my heart indefinitely.

He could never turn the girls in and risk losing Ash forever. But will Ash stay once she learns the truth about him?
