Idon't know about the rest of them, but i am certain that there was fake cum used in one of the first cumbong scenes. It was with Gia Regency i think. There is this part where all of the sudden this big dose of "cum" splashes her in the face. It was quite obvious, they didn't even try to make it look like it came out of a cock.It looked like it came from a cup or something. But there was no way of knowing because you never saw where it came from at all. I think if that was real cum you would have seen the dick.I only hope they don't do this anymore.
