Ooops sorry, but you know english language and me are two different story !!!
I don't know exactly but when I said " not happy " it doesn't mean they didn't get orgasm because my anal system failed only with 1 or 2 girls every 18 months ( it's my personnal official statistic ! ) but it's not enough in many cases to erase from the girls head the fact they did something they don't really wish to do from beginning, but made it because what I told them and for some of them, when they go to shower after, they start to think very hard about their boyfriend, their family and of course of the general opinion people will have when looking her with dicks inside !
This is the main reason why when they go out of shower, they are sometime totally different !!!
