Two Mouths, One Secret (Hunting Housewives). Hunting Housewives

There are women who keep secrets, and there are women who breathe them. Camille had always believed she was the first kind. Faithful, proper, smiling the right smile at the right dinner parties. The wife of Lucas Bennett - a man whose presence was more often felt in the company bank account than in their bed. And then she met Adrian. The first time, it was a glance over a glass of wine at a private club she didn't even know existed.
The second time, it was deliberate. Her friend Sienna had called it "research, " a playful excuse for a night of expensive champagne, forbidden conversation, and men who looked like they'd never been told no. Adrian was different. He didn't flirt the way most men did. He didn't compliment her dress - he told her it would look better on his floor. He didn't ask about her husband - he asked if her lips were as soft as they looked. Every word was a dare.
Every look was a promise. And every time she told herself she wouldn't see him again, she found herself dressing slower, choosing silk over cotton, imagining his voice in her ear. Camille knew where this was headed. She also knew she wouldn't stop. Because once Adrian's mouth touched hers, there would be no turning back. And Sienna? She had her own reasons for wanting to be there when it happened.
