Up Against Your Will (Under The Killing Moon)
It took Phil years to convince Clint that his "condition" isn't something that he needs to protect Phil from, that being a werewolf doesn't make him any less human than he has always been. Clint wants so badly to believe Phil, wants to believe that he can still have a normal life, or as normal as working for SHIELD can be. But when they give in to one night of careless passion, the consequences of their actions may change all of that...
Phil took a deep breath and leaned forward to catch Clint’s face in his hands. Clint’s entire body was sheened with sweat, and even in the dim light Phil could see that his eyes were a lighter shade of sky blue than his normal blue-green, and there was a small tuft of grey fur between his eyes, a barest hint of a coat over the back of Clint’s normally smooth arms and all the way down his spine. He was still human, only with some animal features that looked like special effects make up, and he was the most beautiful creature Phil had ever laid eyes on. “It’ll be okay, Clint.”
