I am looking for a Jav that I watched. As far as I remember mother started to fuck son's bully and later on bully invited an older male to fuck her together. when this was happening, the son entered the room and tried to stop them but they beat him and forced him to watch them. couldn't find it anywhere unfortunately...

There r a lot JAV of such kind. Just google for "JAV mom son bullies", they r all hot and almost with he same script.

I searched many times, even in Japanese but couldn't find it. maybe someone finds it

can you be a bit more specific? who was the actress? how long ago was it? if it was quite a while back, there were only a handful of jav actresses who did those kind of scripts. was the actress busty? or petite? bush? no bush? lol yes i am serious. was the mother willing participant? or was she blackmailed? how did the bully meet the mother? etc.

it wasn't that old as fas as I remember. unfortunately I do not remember the physics of the actress. she was blackmailed at first but later became addicted in some kind. later on the bully invites an older man who looks kinda gangster. i even remember old man getting angry since he started fucking her instead of waiting him. than son came into room and tried stopping them but they instead beat him and fuck her while he was watching. that's all I guess
