what is the difference between milking and hj?

[muycurioso]

I know milking goes with the prostate massage but a lot of porn called milking is just a woman fully clothed jerking a guy off all over himself (sometimes into his mouth). Is this a new term or I am just new to it? Thanks. I can provide links to some "milking" vids later.

That was a HJ. Milking is just what it sounds like. Jerk the guy off into a glass and the girl usually just drinks it..

I have done that a few times
