No one until Her: Risso Family 6 [EPUB ebook] 

Kaden Quinn has life by the balls and enjoys his side job as a Dom in a downtown Boston BDSM club. What he doesn’t want—or need—is a pseudo-sub trying to shred the veil that protects his painful past.
When untamed Livi Risso’s insatiable need to get to the bottom of a story leads her to an exclusive kink club, her curiosity ignites upon meeting a restrained Dom who refuses to touch her.
Kaden feigns disinterest while scening, but that doesn’t stop Livi from experiencing intimacy like she’s never imagined. When one misstep leaves Kaden shaken, will Livi be the one to break down his wall against love?
