Might Be A Little Off-Kilter With This One

So I've been thinking a lot about what goes on between my little and me. You know how you sometimes just have these thoughts that aren't really about anything, but they stick in your mind? It's like that with us lately. We've got the usual routine going, he's responsive, listens to direction, all of it. But then there are moments when I catch myself wanting... more? Like, way outside our norm. He's my little boy, yeah, and we both know what that means in practical terms for his age, but sometimes my head gets away from me. Thoughts like he should be a lot less defiant about doing something naughty because he's young, or why can't he act even younger around other people too? I don't talk to him about it though, keeps things between us separate from that world. But this time it feels different somehow. I mean, we're both adults here, eighteen plus and fully aware of what we do is just a fun game for the bedroom. Nothing more serious than that. Or is there? We try to keep it light and casual like it's meant to be...but there are days I want to push him harder on purpose. He'd never agree to something dangerous or illegal, but still. Just thinking about it gets me in a weird mood, you know? So what am I supposed to do with this stuff? Does it mean I'm crossing some line mentally? Or maybe just because he's been doing so well lately and responding nicely that I want the next challenge, the harder scenario? I don't have anyone else to ask about this. So how does everyone else handle their adult kink dynamics when they start wondering if things aren't normal?
