Wife Material at 28

I’m a stay-at-home parent who hasn’t been in a relationship for years. I’ve grown comfortable with my solitude and enjoy my independence. But there’s something peculiar about the way I fantasize, almost as if I'm daydreaming about being a devoted housewife to someone else's life. It’s not just cooking and cleaning; it gets explicit, imagining myself servicing one specific guy daily, ensuring his every sexual need is met with utter devotion. Tonight, for instance, I found myself in bed imagining him naked beside me, my hands moving over the hard length of him, teasing until he was ready to thrust into me, skin on skin, slick and warm. His movements became urgent, each thrust deeper than the last, and as we both leaned closer to that edge, our breaths mingled with a mix of sweat and passion. When it all finally climaxed, I imagined his body collapsing next to mine in utter relief, our limbs entangled like vines after a storm. Is this just some weird kink? Is it something to worry about? Or is it just a healthy fantasy that doesn’t require any action beyond the bedroom?
