Done Right
Dear Grandma, please don't read this one. It's all spice and almost no romance, you won't like it.

As a grown-ass adult, Emma can't stand the idea of her pleasure being unequal to her partners. After each lousy encounter, she loses more faith in the men on this earth. In a moment of weakness and rage, Emma goes off on Finn Declan, one of the most famous people of her generation. Ranting about your bad sex to a stranger? A bad idea. Accusing said stranger of being crappy in bed? Even worse idea. What starts off as a point to be proven, soon turns into a passion and desire neither of them expected.
