A bunch of these are agents where the girls rotate every few days. Many of the girls are not told exactly what services they will be providing - e.g. they might get sold the dominatrix role but not aware they sometimes need to play the slave (and receive pain etc.) You'll get a much bigger apartment to play around but someone with less/no experience.
- Hidemi has at least 2 different locations in TST. Mostly from Taiwan
- Emley has a bigger flat, more space to play. From Mainland
Then there's independents in Fuk Wah St, SSP. Generally older ladies but much more experienced than above as they now specialise in SM. But they're in tiny 1-room walk-ups.
- Vivan has mixed reviews on this forum, I've never tried
- Yoyo has much better reviews. She's a very nice lady, probably late 40's
- Ka Yan I've never noticed before, also in the same building. Would like to try
The others from your list I haven't tried -
http://go141.com/en/A98706-TST-1 ... art-tormenting.html looks a lot like another agent
http://go141.com/en/A33646-TST-141Walk-ups-slavelin.html also look a lot like an agent
http://go141.com/en/A27406-SSP-141Walk-ups-cici.html looks like pretty regular service actually. She probably got excited and ticked too many boxes on the service list
