Bleu Balls by Tara Lain

Double trouble. The McMillan twins, Robin and Bobby, are renowned for their talents—both as fine artists and for thrilling the various men who catch their eyes. As different in style and personality as their DNA is identical, they’re nonetheless best friends who divide and conquer, with Robin doing the serious painting and Bobby adding the sunny salesmanship.

But when their most important client decides Bobby must wield the paintbrush, the brothers revert to childhood tactics and switch places. Then along comes Micah, a handsome doctor who’s attracted to Bobby but invites Robin out to try to please his homophobic brother, and Paolo, the pain-in-the-butt client who thinks he’s wooing Bobby when he’s actually after Robin. Paolo harbors his own hidden pain that weirdly intersects with Robin’s, but pride and privacy conspire to produce what will either be a masterpiece—or end up as Dogs Playing Poker.
