Gay and happily married, Leo has helped manage a large, influential nonprofit arts foundation over the past ten years. He has built a friendly rapport with the elderly billionaire who began it, but he has enemies within the foundation.

Leo’s birthday is on February 13, and that has always meant candles on heart-shaped cupcakes and birthday cards with “Happy Valentine’s Day” crossed out. To celebrate, Andrew, Leo’s mystery writer husband, arranges a tryst for Leo with Mel, a gifted violinist who is one of Andrew’s biggest fans.

What started as mere pleasure becomes a three-part harmony as Leo, Andrew, and Mel explore the ways their kinks and needs mesh—until Leo’s enemies attempt to use evidence of the liaison to force him out of his job.
