You have sex with an asshole. And it is
good. After having said sex, the asshole has been stretched to such proportions that you can put some kind of
small trinket inside for the next person to find. It's a surprise!!!
Upon inserting
my penis, I found an oddly shaped
d20. I wondered how it had gotten there, and then remembered her last boyfriend had been into anal plundering. I continued to fuck her, not
testing my luck.
