I have had few really good sessions with South American girls. But yes, success rate is lower than Asian MLs.
That’s y I prefer GC shops for non-asians, don’t know why, but the success rate is higher in GC and options on the menu are more compared to Brissy.
In GC, I was readily offered all the options for 1 pineapple however, I use all my communication skills for 15-20 mins during the session to get it from Bris MLs that too for 2 pineapples, which you may not get next time with the same ML.
