The Sizzle Paradox - Lily Menon

Lyric Bishop and Kian Montgomery, both graduate students, are best friends and roommates. When Lyric needs help cracking the Sizzle Paradox for her doctoral thesis on sexual chemistry--it seems the more attractive she finds a guy, the less "sizzle" there is when they actually have sex; but why?--Kian, who never has trouble in the bedroom, offers to tutor her on dating tactics. Lyric, being a self-proclaimed awkward potato, accepts the help she desperately needs.

But once the two progress with their "tutoring sessions," they find that the solution to the Sizzle Paradox might actually be having sex with each other. Which is a problem, because they're best friends and absolutely, irrefutably nothing else... Right?
