My Husband and I Tried Roleplay for the First Time

I'm a stay-at-home mom of three kids under ten. My husband works long hours as an accountant, and we've been married for eight years. The sex has always been good but predictable, no big surprises or experimentation. Recently, he brought up trying some roleplay, something different to spice things up. I agreed, though it made me nervous. We chose the 'teacher' fantasy first - nothing too extreme, just a light variation on normal. He dressed in one of his old suits and wore glasses. I put on my favorite little black dress with thigh-high nylons. We set up some basic furniture to create an office look in our bedroom. It was weird but fun. He called me 'Miss Johnson' when I entered the room, all proper and formal as if we were back at school. I let him instruct me a bit like a student - answering questions, reciting facts out loud. Then he took off his glasses and tie, letting go of character some. The roleplay faded into our real dynamic. Next came the physical part. He undid my dress slowly, running hands along my shoulders and neck. I unbuttoned his shirt buttons one by one, enjoying that sense of power and control over him in this scenario - something new and exciting to play with. His cock was already hard as he laid back on the bed, me hovering above ready to ride. He grabbed my hips and pulled me down on top. I felt so full inside as we started moving together, his hands leaving marks on my thighs and ass from holding on tight. The fantasy gave us an extra layer - I imagined myself as a new teacher just starting at this school, the forbidden thrill of being with the principal himself. He leaned up to kiss me roughly, tongue probing in my mouth. It was exhilarating to let go, take risks together like that. We came quickly but hard, bodies shuddering and gasping for air as we spilled inside each other. Afterwards, we cleaned up, dressed back normally - the fun fading away with practical needs. He pulled me into a hug, still breathless from all the new sensations. So here's my question to everyone reading: What roleplay fantasies do you or have you tried with your spouse/partner? Any favorites? I'd love to hear your thoughts in the comments.
