Mark envies his friend Sebastian and the Cougar who tamed him. For years he’s had his eye on a sexy, older, married woman. Despite his and Bastian’s sexual adventures, he refuses to poach outside his steamy fantasies.

Sloan travels with the race car drivers as the league’s publicist. Living abroad can be lonely, especially when touring somewhere like China—where beautiful landscapes surround them but language and cultural barriers are high. Until she meets Lynn, who shares her love of erotic romances. In Lynn, she gains more than a friend because sexy-as-sin navigator Mark is never far from the Cougar and her fiancé, making Sloan wonder if it’s time rejoin the dating scene after a nasty divorce.

When Lynn notices the chemistry between Mark and Sloan, she issues the Cougar Challenge. Sloan never imagined she might grant her younger lover the strength to explore the sexual tension that has been building between him and his friend since their Cougars entered their lives.

Four friends, two couples, one night none of them will forget.
