I remember reading this thread sometime back and even commented on it. I've seen @EasyEntry mention his trailer hitch ball as an avatar.
Anyway, two of my trucks were equipped with trailer packages and I had a trailer hitch that I used for rented trailers(mostly to move furniture from place to place). I used a 2.0 inch ball hitch for all my trailer use even though I had a larger ball to use in the event I needed it.
Anyway, today I was sorting through some stuff in my garage when I came across my old trailer hitch, ball, mounting pin, etc. It still had the 2.0 inch ball mounted. But what I also found was my new, unused 2-5/16th inch ball hitch. It was unused and shiny in one of my workbench drawers.
I took it inside and checked out. Shiny with a good chrome electroplating, I cleaned it off, lubed it and slipped it into my rectum. It is quite heavy and provided a nice weighty stretch to slide through the anal sphincter muscles. It eventually did pop through and laying down, gravity and relaxation drew it deeper inside me. I drifted off to sleep for a short nap and it was a lot deeper than I expected.
I did have to stand up carefully because the effects of gravity could have the ball hitch just fall out to the floor..
For the record, my ball hitch weight is 1270 grams without the nut installed (2.8 pounds). With the nut threaded onto the base, the weight increases to 1390 grams (3.1 pounds). Great training for strong muscles. As I drift off to sleep, the mass reminds me that it is still there. What a way to be plugged.
