Tasting yourself with your lover

I (41m) have always thought it was extremely sexy to see women playing with themselves, then licking their fingers clean!

My early sexual experience was with a girl who was afraid of cum, so when she asked me to taste myself first, infront of her, after an amazing hand job, I didn’t think much of it, and complied.

She eagerly jumped on the bandwagon, and I never was asked to assist again.

I find myself obsessed with the dirty idea of cleaning up creampie pussy, much to the disdain of current partner (40f), whom also is not a fan of performing oral.

While she has let me masterbate into her hand, and shoved her cum covered digits in my mouth, it’s always been with disgust, not in a femdom way, but true disdain for the act.

I would be ecstatic at a woman who would perform oral on me after penetration, as it’s a sexually accepting act to me. I’ve told her the idea of being trained to clean her up is what I hunger for, but any attempts from her are half hearted begrudgingly acts.

Any tips or similar experiences?
