Great thread. Haven't had the time to check all of it, so I'll just post this, hoping this will be new for somebody: for me, the whole idea of this prank with getting handcuffed with a string and a bell tied to your dick is so outlandish I'm almost sure it's entirely made up for JAV reasons. At least I hope so. The shots are great though. So much time can be spent teasing... in Western porn such a thing is niche and you would have to stumble upon a random video with like a minute of it tops. But here, it can take dozens of minutes
The whole "girl watching the process of erection" can also feel dumb, but again, I just love that we have Japanese people to make whole movie series out of it
As I and many others often think and say, "The Japanese are so f***ing weird... God bless them"
