Stepmate's fingers drive me to multiple orgasms

I've been craving some steamy action with my stepmate for ages. She's a total nympho with a killer body - big tits, a juicy ass, and a lust for life that's off the charts. I know, you're thinking she's my sister, but trust me, we're not related by blood. The other day, we finally decided to take our taboo desires to the next level. We started with some intense fingering action, her skilled digits driving me wild and sending waves of pleasure coursing through my body. Before I knew it, I was on the brink of an orgasm, my body trembling with anticipation. And then, the climax hit. I exploded in a fiery display of pleasure, my body convulsing with the sheer ecstasy of it all. But the fun didn't stop there. We continued our wild ride, each of us lost in the throes of passion. I can't remember ever feeling this good, and I know I'll be craving more of my stepmate's magical fingers.
