Helt utsatt på en naken promenad bara med kyskhetsbur

Walking naked and locked in a chastity cage on the dirt road without any emergency clothes. A friend commanded me to lock the cock in a new smaller yet very comfortable steel cage, wrote the "SLUT" sign on my lower abdomen with henna color which stayed visible several days and asked me to take this nude walk. All clothes stayed near the road behind the tree, I forgot they are quite visible... One biker very probably saw me. He was passing by when I was trying to hide. He did not stop and fortunately he didn't do anything with my clothes. Hiding in the grass gave me some scratches, ouch! In the end I decided to add some butt slapping and as you can see, my butt got nice red color.
