Here's a PRC in SG that does SM.
Her name is QiQi she used to be a 女王 back in Hunan.
I would say her style is milder, more nurturing style, rather than the very strict and aggressive type. She is familiar with dog training, feet worship, humiliation, spanking etc. I think she is open to anything so just discuss with her beforehand.
Don't expect Japanese-level dominatrix but she's not too bad given the limited options in SG．And at $100 per hr, she's value for money.
Appearance-wise she is rather attractive - her figure is good (36D), curvy, sexy. Her face is plain but overall she's sexy enough to get you hard the whole session.
I would say she's more attractive than recent PRC mistresses in SG such as Poison and Butterfly so I recommend all to give it a go.

If needed, she can double domination session with her friend:

Haven't tried Bai Xue before so no reviews on her yet.
Anyway it's $100 per session (1 hr), so i suggest all interested to give it a go. And please don't spoil the market for bros here by raising the price. Given the influx of PRCs in sammyboy at the moment, $100 is a fair market price.
