"And what brings your pretty face here, sugar?" Stiles purred, making Derek growl. "Tell me, dear, what can I do for you?" "I need you to take care of someone," Derek said, making Stiles raise his eyebrows. "Don't act as if you didn't know what I was coming for, you're a demon, you know everything." "That's very true," Stiles' plump lips turned upwards info a cocky smile, something that made Derek's stomach churn. "I'll take care of anyone for you, sugar, but only if you give me something in return." "Like what?" Derek asked, voice soft. His heart was beating quickly in his chest, fearing for his own life. "Your body, sugar, I want your body." The devil answered, making Derek gulp. Was it really worth it? Was Kate her death worth giving up his body? Derek thought back about how she had murdered his entire family, how she had burned them alive. "Do we have a deal?" "Yes, we have a deal." Derek nodded, making Stiles grin. "Good, sugar, very good."
