I started to feel devotion with Meije-san: we are always in agreement ;-)
So, he is right, with delivery health you expect you can satisfy that kind of expectations (i am geltile man, and i always like to return favours to my couples, for me is somekind of politeness rule...). I tried in soapland and it was well received, but in that "scripting service" maybe is not the usual thing, and it not fits very well (that ladies just want to do the same as robots with no sorprises, so i would say is not normal for soaplands). I also tried in pink salon and well received, but the lady was absolutely disgusting, and i really needed all my concentration to successfully completed my task. So, just repeating what Meiji-san said: just exploit the fact that that practice is legal so you can freely ask about that to your operator (for deliver healthy). Believe me, "kunni" (thanks sqrhead-san ) is so normal stuff, i am still sorprised with the things japanese men are able to do inside sex industry in Japan (all you can imaging these people can do it, and some of these things are really hot, but we cant try because we have not great "nihongo" skills... shit!)
