被锁在尿道贞操装置里的流浪者

I was wandering around in the nature while locked in chastity device with urethral tube. I was trying to wank but it was quite difficult in the device that prevented erection and fixed the cock from inside. In the end I was able to cum. Cum just dripped out from me around the urethral tube. The feeling of the pressure while my balls were draining was suberb. I think I should do it locked like then more often.
