Wild Boys After Dark, book 2: HeathMelissa Foster2015

Everything's naughtier after dark...
No last names. No strings. No ties.
Except of the silk variety.

Dr. Heath Wild and Allyson Jenner only wanted a simple tryst. But Heath couldn't live with just one night, just one taste, of Ally--and Ally couldn't escape the memory of his hands on her skin, the way he looked at her like she was his obsession, or his seduction, which had pushed her to the edge and had made her want to do things she never had before.

One night leads to one tantalizing phone call. Can one phone call lead to forever?
