Threadstarter, it seems like u r asking for the moon considering your list of pre-requisites u posted here!
So what if you are tall, dark and handsome??!
In GL, $$$ is above anything else! Even if you are a fatso with Mark Lee's poke marks all over your face but u r generous in tipping$, the WL are more than willing to service you like a KING!
FYI, tarma session is 60 mins and not 90 mins. Tarma 60 mins = S$300. If you want 90 mins, the OKT will still charge u for 120 mins which set u back at S$600!
It is alot easier for OKT to arrange if the 2 WL are from the same house. It is better to let the OKT selects the wl for you as he knows which 2 wl can coordinate well in tarma session in order to achieve a sextisfactory session! If not, choose the wl you like and ask this wl choose another wl she thinks she can tarma well.
