I don't mind if they are honest about it, it's just a fantasy. It's when they pretend that it gets annoying.
I don't mind either, as long as the performance is good. Though I am interested in how they "make the switch"!
They usually hold the shot from when the guy delivers his final pumps to when he pulls out and we watch it drip from her clam. It's pixelated but we do see something white spill out of there.
Again, I don't mind of it's fake. WANZ had two popular series, "Wait, Did You Just Cum Inside Me?" and "The Condom is Torn During Accelerated Piston Sex" with ridiculous premises involving one guy repeatedly cumming inside the same actress in one session. The the nakadashis are clearly simulated (I think maybe the final one might be real cuz they keep the camera on it, with no cuts) but that's okay IMHO. The premise is kinda silly, were having some fun and we get to see sexy women in every conceivable combination of height, body type and hairstyle moaning and groaning with pleasure! You want a gal with a sexy body, you've got AIKA. In the mood for someone a little bit chubby with soft, thick thighs and big tits you got MINAMI Momo. Want a petite, slightly boyish girl next door in uniform, there's SHIINA Sora. Do I care if the guy actually shot or not? I'm more concerned with whether or not I did!
But I still wanna know how they fake it! I guess growing up on DVDs made me a behind the scenes junkie.
