My Boring Week Turned Wildly Out of Control

I work in a dull office, and my partner and I have been together for years now. Things were going fine, until this week when I started feeling stir-crazy with the monotony. I mentioned it to them casually, and they playfully suggested trying out some roleplay to spice things up. So last night we tried our hand at a very light dominance and submission dynamic, just holding hands and calling each other 'Master' and 'Servant'. It felt surprisingly freeing to take on these roles. We ended up pushing it a bit further than planned, adding blindfolds and restraints. The intensity grew as I found myself wanting more control, but we both kept checking in with each other's limits. By the end of it all, there were welts on my arms from playful spanking and I was gasping for breath after being bound upside-down for a few minutes. Afterward, I felt embarrassed by how much I enjoyed taking charge and seeing them submit to me. But also strangely content, like I’ve been harboring hidden desires this whole time. What the hell am I supposed to do with this new side of myself? Our relationship isn’t about power exchange, but I can’t ignore these urges now that they’re out in the open.
