I think that it was in the 70’s when Barbary Hershey & her hubby David (?) had real sex in a flick they did & 9 months later their kid Free was born. She planned it that way too.
I’ve heard from camera operators that the guy making ugly faces part of the cum shot is put in the movie for editing purposes. When the film is edited from hardcore to softcore, they remove the actual money shot and leave in the face contortions so you know what just happened.
As for my recent academic viewing habits, I saw an AVI from the web where the money shot was deposited on the woman’s glasses as she wore them. This new (to me anyway) twist did something to me. To quote George Castanza - “I think it moved.”
OK, are we ready for a new game?
I’ve always found it entertaining to ask people to describe what it tastes like. Most men have tasted their own at least once. (If you like, we’ll believe you when you say it was by accident.)
I’ll save my favorite answer for later. So…
What does it taste like?
Baking soda.
Whaaaaaat? 
Usually they splice cum shots together from multiple camera angles, Etc, giving the impression the guy has the cum capacity of an elephant (1 quart).
With all the special effects hollywood can do I found little support here over the years that they would ever use those special effects to create fake come shots. At least they can be faked inside.
Just wanted to adress the “two condom” thing someone mentioned.
Don’t ever do that unless you have a severe problem with premature ejaculation. They rub against each other and breach far more easily, think about it.

in porn, these women are supposed to be far removed from all things “prudish” and “motherly”, thus the cum shot–you can’t get pregnant with semen on your tits.
Cuming inside someone, however, is far sexier, even if it is just sexual, and not for pro creation.
