hey bros,
if you like professional domme with both looks and skills, do try mistress ayumi in hongkong,
http://www.mistressayumi.com/about_me.html she charges 3000 hkd for outcalls and 3500hkd for incalls. assuming that the exchange rate is still 5.7, outcall can set you aside 526 sing and 616 for incall. her dungeon is at central.
For cheaper alternative, take a train to shenzhen or guangzhou and you can get a double dominatrix for as cheap as 800 reminbi. thats about 200 sing. This is the website for china dominatrix,
http://zhimay.info/ It is in chinese characters and one needs to register before being able to see the profiles. registration is free. Hope it helps
Regards
