I used my neighbor's vulnerability by the window to penetrate her anus as our other neighbors observed, forcing us to conceal ourselves

I've always been a fan of the thrill that comes with risky encounters, especially when it involves indulging in my deepest desires. I live in a building where the windows are thin enough to hear my neighbors' intimate moments. One day, as I was enjoying the sounds of my neighbor's solo pleasure, I couldn't resist the urge to join her. I snuck over and found her on the window sill, her big ass and big tits on full display. I took advantage of her vulnerable state and penetrated her tight anus, giving her a creampie she wouldn't forget. As we were caught by another neighbor, we had to quickly cover ourselves up, our hearts racing with excitement. The thought of being watched only made the experience more intense. Later, we would laugh about it, but the memory of that spontaneous encounter would be forever etched in our minds.
