Cass sighed a bit, leaning his forehead against Percy's. He couldn't deny that he was frightened, but he did know what he wanted, and he did know that the issue would never ever be Percy.
'You're not pushing. It's my choice. One I took my time making.'
He smiled, almost nervously, playing with the hair on Percy's neck. 'I won't deny that I'm scared, feel like I'm way in over my head and am worried that I'll screw this up royally, but what I have no doubt in my mind about is that it's you that I want. I wouldn't do this with anyone else, no matter how hard someone pushed. Last time someone did I actually left the country, and I never spoke to her again. This is...new, and slightly overwhelming, but it's what I want to do. With you.'
Leaning in he kissed him again. 'I told you already, it's you I want. That won't change.'
