If you didn't already know, Oreo cookies are great with cum. For this game, removed one of the cookies. I then carved out a small section of the cream filling to create some empty space inside the Oreo. Edging my cock, I dropped a small shot of cum into the space. Finally I replaced the top cookie to complete the process and placed the Oreo with my cum inside with the other ordinary Oreo cookies. Mixing up the cookies I had no way to know which Oreo had my cum inside until I ate it. You can see the whole process below in the pics.
