Update:
I work in an office suite with other businesses, but people pretty much leave me alone. I occasionally have visitors drop in unexpectedly, but there’s a lock on the door for that.
I brought a pair of gym shorts to work. Now, when I hang, I can freeball through the shorts, i.e., without being practically buck naked. I also got a dog chain for holding the weights. It has a loop that conveniently attaches to the Bib.
With this arrangement, I can detach the weights, unclamp, throw everything in a drawer and be to the door in about 5 seconds.
I just hope I remember to put my dick back in my pants.
