My stepson Alex was always a handsome guy with big tits and big boobs, but I never thought he'd cheat on me with that Mckenzie Lee slut. It all started when we moved into this new house, and I caught him sneaking out to meet her in the woods behind our property. She was always so loud and obnoxious, always making a scene wherever she went, but he couldn't get enough of her taboo actions.
One day, I decided to spy on them when they didn't know I was around. I hid behind a tree and watched as Mckenzie Lee sucked Alex's cock in a doggystyle position. She had huge tits and big boobs, but nothing compared to his. They were both so into it, moaning and groaning like animals.
I couldn't believe what I was seeing. My stepson, my lover, cheating on me with a MILF like her. It made me feel a mix of anger and arousal. I knew I had to do something about it, but I also wanted to join in. I decided to take matters into my own hands and make them both mine.
I approached them from behind, making sure they didn't notice me. I wrapped my arms around their necks and whispered in their ears, "You two are fucking like rabbits, aren't you?" They were so caught up in their taboo affair that they didn't even react at first. But then they realized who was standing there, and their faces turned red with embarrassment.
I leaned in closer and whispered again, "Don't worry, I won't tell anyone about this little secret of yours." They looked at each other nervously, unsure of what to do. But then they saw the sinful smile on my face and decided to play along.
"Okay, step mom," Alex said, "but only if you join us in our taboo fun." Mckenzie Lee nodded in agreement, her big tits bouncing with excitement. I couldn't resist any longer. I pulled them both close to me and started performing oral on them at the same time. It was a steamy, taboo threesome that neither of us would ever forget. And we all knew that our stepson and his MILF lover had just become mine.
