Dirty Little Desires by Cassie Cross

Oliver Warren is a man who seems to have everything. He’s rich, he’s handsome, and he owns of some of the hottest properties in the country. The only thing missing in his otherwise perfect life is the woman he’s been in love with for as long as he can remember, Felicity Williams. She just so happens to also be his best friend’s sister.
Felicity co-runs a successful lifestyle website with her sister-in-law, and she has a line of accessories in the works. Most of her dreams are well within her reach, except for one that she’s been keeping a secret, and she needs Oliver’s help to make it come true.
Felicity hatches a plan to attend a benefit that’s being held at one of Oliver’s properties, and brings Oliver as her date. After a long weekend of ups and downs, Felicity starts wondering if the feelings she has for Oliver aren’t as unrequited as she always thought they were.

When they get home, will love be enough to get them through the fallout of giving in to their dirty little desires?
