I went to HK recently. I had a weekend to recover from a hard work week and did not want to leave the hotel really. So I ordered an outcall massage from Kaishun Massage. Can Google it.
The service was quick and easy. I described the girl I wanted (young, petite, smiling). They matched it well. I ended up with a small, petite, 25 year old named Annie. Very cute and smiling a lot.
Price advertised on the website was paid. That included a decent nude massage and HJ. I upgraded $400HKD for BBBJ+Facial. I took full advantage of the arrangement and face-fucked her hard for about 15-20min, had her lick my balls, deepthroat as best she could (she was really a small girl), then came on her face. I had her down in a submissive position, hands on the ground, grabbed her ponytail and really did rough porno stuff. She took it all including a huge shot to the face then smiled and laughed like we just played a fun game.
After she cleaned up, she finished the massage face up and we joked and cuddled. She was about half my size and less than half my age, so it was like being with a joyful small girl from my youth.
Overall not cheap (probably less than taxis, drinks, and clubs, though) and a good experience.
