Months after being stricken with an incubus-like curse, the boys are building an ever-strengthening partnership out of the wreckage of its intense sexual requirements. Now, the ongoing physical relationship the sex demon forced on them has become a comfort to them both, and Sam’s even finding ways to use the power they generate to make them better hunters. Of course, Sam can’t always control his powers, and he’s still having flashbacks to the captivity and torture that started it all. Dean’s going out of his mind trying to help, but his brother’s not the easiest guy to read, and Sam is definitely not in a talking mood. How far are they willing to go to make things right again?
