My suggested figure (of 7,500 - 10,000 HUF) appears to be low after the (high 140,000 HUF) price you paid. My concern is that there is an overpayment of up to 19 times, and if you paid a sex worker 19 times more than the "natives" are paying, then you raise the girl's confidence. She's going to be even more confident the next time! The girl is far more likely to raise her prices, even more so, when the next "foreigner" gives her a call, and then all your fellow mongers are going to suffer!
There are great many "classy", and "nice" girls all over Budapest who are ready, willing, and able to do whatever you want to do with their bodies. Whatever your desire is, just let them know, in advance, and amazingly, for 10-20% additional money, you will get exactly what you want, regardless how unusual your desires are! This way you overpay, by a factor of 1.1 or 1.2, not 19.0. Especially now, in September, when the tourist season is already over, when business is relatively slow, and it is getting kind of chilly outside.
It is not the easiest thing in the world to go to a "foreign" country and find someone lovely, and find her in five minutes or less, without speaking Hungarian, and without shopping around. This is what most outcall/escort services count on. They want and need customers who are willing to pay anything, everything, including their outrageous asking prices, in return for quick and quality service. Especially when business is slow, especially now, when the season is already over. They desperately need "rich foreigners" who pay their outrageous/enormous/shockingly high asking prices.
But there is a better way. For example, if you shop around from the U.K., or wherever you have access to high speed internet service, you can easily find names and addresses of freelancers. Also, the U.K. is a multi-cultural society, and, for a few pounds, or even FREE, you can find somebody who speaks Hungarian, perhaps a starving student, or retired person, a complete stranger who is willing to make a few calls for you! He will find girls for you! He can easily make 10-20 girls beat down your door, and fight for your attention, and compete for you, in your hotel, even before you pay them!
The possibilities are endless! For this (very high) price of 140,000 you can have not one, but 15 bare, naked ladies give you the best time of your life, with your pleasure so intense and intoxicating that you would never forget it, for the rest of your life!
