Mistress Menage by Jenesi Ash
Meet Amaris Martin, ambitious career mistress to a millionaires. In this the bawdy, naughty adventure, Amaris's lover Leon loses at a high-stakes Vegas poker game, and a night with Amaris is part of the bet. Rather than being outraged, Amaris is delighted — the man who won her is very sexy...and even richer than Leon! Approaching the night as a potential job interview, Amaris is dismayed to discover the guy's already got a mistress who's not too keen on the ménage a trois he has in mind. But by the end of the night, Amaris is sure she's got herself a new benefactor...until she wakes up the next morning to find his dead body in her bed, and her rival claims Amaris killed him.

Wet by Lauren Hawkeye
All I wanted was to escape my stifling grad school dorm room and soak away my stress in the nearby hot springs. Then I meet Susan and Adam, a slick city couple who intrigue from the moment I spot them at reception. And from my first encounter with Susan in the pool, it's clear I've caught their eye, too.
But once they offer me up to a complete stranger and take us back to their suite, I realise I've been made a pawn in their own sexual game. A game in which I don't know the rules and I have no idea what might come next...
