You'd be surprised, but if the male actor is but an extra or soup guy, they actually do not get the pleasure of actual stimulation haha
Is more about the male rather than the female.
I was looking through the jav leaks and there was one file named "bhd1080.com@20160926194650.m2ts". It’s basically the camera guy walking in on the actress showering and convincing her to give him a blowjob. It looked like this video was filmed on the same day as LUXU-465, but this footage was never released publicly. He walks in and tells her good job on the shoot, and if she minds if he interviews her about the scene. She looks completely shocked as it looks like this was totally unplanned.
Then he gets completely naked and gets in the shower with her. He talks about how sweaty he got from working the camera and if she could wash him. He points to his dick. From the look of his body you can tell this is definitely not the same guy she fucked in the main scene. This guy is fatter and his penis is smaller. He asks if his dick smells sweaty and she starts smelling it all over. He talks about how hard he got when he was filming her doing the scene with the actor. She then starts giving him a blowjob and finally he cums on her face and she swallows a bit of it.
I wonder if this guy has a whole bunch of private videos like this with different actresses. Or maybe this was supposed to be a bonus scene, not sure.
Pro-tip, you can use the plain bbcode tags to undo some automatic formatting by the forum, like making that filename into an email address link. You just gotta toggle the editor to BB code on the top right to see them.
