I know about fake creampies (mixture of egg whites and etc), I know about some using fake cocks. I know about some using their fingers (bj's), I know about limp dicks and the fake moans, I know about actress just sitting on top yelling and no penetrations, I know about using syringes to insert the fake cum, I know about quick cuts and slight of hands when you see the actors reaching for thighs, but a penis extender is a new one for me
Honestly, a porn studio is like a movie/tv studio, they have tricks for their audiences.
As a stated before, the mosiac, love it or hate it, serves a dual purpose imo
As AV becomes less and less profitable and the wages decrease, do the actress really want to do all of that for little money?
