I think these super rough irrumatio scenes with puking and choking etc drive many girls out of the industry/genre once they do them. Its obviously a very unpleasant experience for the girls, it is very very rarely something they enjoy. Im sure there are a very small percentage that actually enjoy it. I have seen a lot of girls that are very good deepthroaters, do these scenes, or star in a scene that is a little too much for them... then they pull back from blowjobs completely. The realisation must hit them... i dont want to be a jav star that just gets her throat fucked where every scene a guy is trying to force his dick down my throat. I much more enjoy the girls that so "self irrumatio" or are allowed to be in control. ts very rare that a girl would actually not be traumatised by being in a room with a bunch of guys forcing their dicks down her throat until she chokes on her own vomit and is turned into a complete mess. The best example is the notorious case of Honoka Takigawa from ENKI-023. She filmed that dvd then slowly withdrew from the industry due to the fact she really hated her experience there. You can see in the scene where she is deepthroating guy after guy that she is in pain and is not enjoying it at all. I feel like these irrumatio series push a lot of good deepthroaters out of the genre completely and sometimes out of the industry
