I interrupt my stepsister for oral pleasure and intense orgasm

I was minding my own business, walking down the hallway when I stumbled upon my stepsister in the guest room. Being the nosy type, I couldn't resist peeking through the crack of the door to catch a glimpse of what she was up to. To my surprise, there she was, on her knees in front of her mother-in-law, doing the dirty deed. I quickly retreated, knowing full well that what I was witnessing was off-limits. However, the sight of her skilled oral prowess left an indelible mark on my memory. Days later, I found myself back in the guest room, seeking out the forbidden fruit. As I knelt in front of my stepsister, I drew on the lessons I'd learned from her earlier encounter. I had no idea what I was getting into, but the thrill of the taboo and the taste of her sweet nectar left me in a state of euphoria. It was a wild ride I'd never experienced before, and one I'm sure I won't forget anytime soon.
