We're An Odd Couple

I met Jules four years ago when she was barely 18 and working as a barista. I was 48 at the time, conservative, and she was and is a rebellious SJW, but we developed a good enough rapport that we could cut up and talk. She trusted me and we flirted back and forth over spirited conversations and we eventually ended up in bed. I'm a middle aged man with a dad bod and she's a very pretty, spunky girl with multi-colored hair and anyone would assume we're father and daughter.

Honestly, we have really good, dirty, kinky sex and she loves being treated like the brat that needs to be controlled. One time she was on top of me and smarted off and I smacked her ass and jokingly called her my "little spunk bunny" and the name has stuck because it makes her feel like a dirty girl. Over the last four years we've come to love each other as friends, but neither of us wants a relationship and we both like the FWB thing we have going. I'll always have her back and she'll always have mine but she's always going to be my little Spunk Bunny.

Fast forward to now, we're on her third boyfriend that she has picked because he's easy to cuck. She doesn't hesitate to tell them about me and when she brings them for me to meet, I always do the "dad" thing and make sure they're intimidated of me with the twist that Jules and I fuck and that is not changing. She loves it, having guys her age that will do all the things she believes in, but she dumps them pretty quick when they say that she has to give me up. I kinda like it and we both fuck who we want to fuck, but in the end my little "Spunk Bunny" always comes home and happily climbs on my cock because that is her safe space where she doesn't have to care.
