Right, there's KNOWING something is fake vs. obviously fake. As a rule, you can just assume something is fake about the AV you are watching. Fake boobs, fake sperm, fake sister, fake student, fake amateur, fake cherry boy, at the very least, the names are fake.
But making the fake look real enough that's film making mastery. I'd wish they would just dial back the ridiculousness a bit. When some so-called professionals can sport a sub-3" baby pecker, don't try to sell us some some 18" garden hose spraying a gallon of gel. Just give them so solid 8-12" rubber dick, spend some money on cosmetic to make it look real, use some smart camera angle and train the actors to act natural. Most importantly, have some gadgetry to squirt some impressive but believable cum shots. The amount must not be too much, once the total amount is over like 5 or 10ml, it becomes runny and doesn't stay as a splotch or streak. Like suntan lotion, the first squirt on the skin looks dirty, or like the English say, rude. Couple more squirts, and it quickly just become boring skin lotion. The most important thing is the shot, it must be forceful (with the small amount of fluid) and my personal fav is when the first drip is so forceful it glance off the girl's face.
Then... with a fake dick, it's no problem going right back to piston pumping, and after some of that, the first cum shot might have dried off mostly and timing is just right for the next cum shot. That way you can make a realistic looking life action version of the standard hentai manga covered-in-sperm scene.
Oh another nice thing about fake dick is that it's easier to make (fake) an impressive cream pie.
Hey... with my ability in engineering, I bet I can make a miniature remote-controlled ejaculator pump that fits inside a fake penis (may need the space of a fake scrotum too) and shot some impressive but believable cum shots. You think the studios would pay me for such an invention? I accept USD, Yens or girls
