I was minding my own business when my neighbor knocked on my door. As I opened it, I was met with a sight that left me in awe - a stunning woman with a body to die for and a round, luscious ass. She had brought along a sleek black sex machine, ready to take our pleasure to new heights. Her ass was the perfect fit for the device, and she eagerly mounted it, bouncing on the saddle as I watched in awe. The sight of her inverted ass being stretched by the machine was a sight to behold. Soon, I joined in, taking her from behind as the machine continued its relentless pounding. The experience was nothing short of incredible, and we both were left thoroughly satisfied. As we recovered from our intense session, I found myself hoping my neighbor would come back soon.
