I thought this would be a fun thing to try. I'm not young enough to get an erection on demand, so keeping it erect while trying to get it in a sock was a challenge. Then the pain of trying to fit my balls in there!!! I could barely get one in. The second involved a lot of tugging and compressing.....But I got them in.....At the cost of a full erection. I really didn't know what to expect, after all I'm not really large compared to you guys. But the sock was shorter than I expected, and super tight mid-shaft, as well as squeezing my balls like they were in a vice. So I guess I didn't do too badly under the circumstances.
After all, the sock was full, and I was this soft.
