Excellent question. To be honest I'd have to check the video to be sure, but if I recall correctly, I handed him the key in his right hand. I was thinking of mentioning that in the post, but it was difficult to see it in the pics. I tried to zoom in on these pics yesterday when I posted them. I think you can kind of see a bit of black in the last pics inside the chastity cage in his right hand. That would be the key. Can you kind of see it there? If you don't already know this, you can click on the pics to enlarge them to full size. Then you can click "stop slideshow" to stay on that pic, then you can zoom in from there.
