How to Pick this Master Lock?

I can't see the pins inside, and my tension wrench just keeps turning when inserted.

That's a warded lock. It doesn't have any pins inside of it like a typical pin tumbler lock does. You'll need to use a warded lock pick, which is basically a skeleton key by definition.

A lot of pick sets from Southord come with a set of warded lock picks like these:

They are the same kind I have, and they work quite nicely.

I am pretty new to lockpicking & recently discovered how disturbingly easy it is to open this kind of lock. I even made my own skeleton key out of an old key. Looks like this...

Yeah, just from looking at the picture, and the fact that he has one post, and clearly no interest in browsing the site to find the answer (which I just did and found within 1 minute), I'd say this for for something illegal.
