Caught in a Kink Experiment with My Wife

Hey there everyone, I hope you can help me out here. A little backstory might be needed to understand the situation. Me and my wife have been married for about five years now, and we've always enjoyed exploring each other’s desires in bed. She's in her late 20s, and we both have a playful relationship when it comes to trying new things. Recently, I felt like maybe our intimacy had become too routine, so I suggested we try something different together. We agreed that roleplay might spice things up, especially because she loves the idea of me being someone else for a while. The night before, we talked about my fantasies and her own desires, and surprisingly, it turned out we both enjoyed the idea of a bit more dominant play in the bedroom. I figured since we were both adults and this was just roleplay, it wouldn't be a big deal if things got a little steamy. So last night, she asked me to tie her up gently as part of our game, something that I've never tried before but found quite thrilling when we discussed it. We had agreed on boundaries beforehand, and everything was going smoothly until... Well, you know how sometimes roleplay can get intense? She really got into the character and asked for more than I initially planned to give her. I have to admit, despite our prior conversations about limits, there was a moment where she seemed to push things beyond what we had both set out. Now, after everything cooled down, I’m wondering if this was just part of the game or if I overstepped my boundaries as the one who usually takes on more control in real life. Should I be concerned? Do you think it’s normal for a roleplay to become so intense that the line between fantasy and reality can blur at times? It feels like maybe we need to have another conversation about what's okay, but also how far is too far. We’re both 18+, and everything was consensual, even if she did take things in an unexpected direction. I'm just trying to figure out if this means we should continue with something similar or take a step back from the roleplay idea altogether.
