I have engaged their 'escort' services once.
The 'Yuki' I got was not the 'Yuki' you see on the site. While the girl I got was not unattractive by any means (she was in fact, quite cute... but the one in the pic is still better), I was not too impressed by the fact that this is another site that uses fake pics.
Add to that the fact that I was told 20 mins before my appt that it would be 'slightly delayed' by 10-15 mins. Fine. I was already on my way, so I just took a VERY leisurely drive down to the appointed venue. Reached and got another call, asking if I can make it 45 mins later instead. Sensing my displeasure, OKT quickly makes it '30 mins' instead. Waited till it was 40 mins after the originally agreed time. I was just about to write it off and walk away from the deal when he called and gave me the room number.
Up I went, reached the room and rang the bell. No response for a minute. Worried I might have heard the room number wrongly, I called the OKT to reconfirm. Nope, I had the right number. At this point I heard a bit of commotion from inside the room, suddenly the door opens and A CUSTOMER walks out... Talk about poor management.
Anyway, not really in the mood to write an FR on this crappy experience, so just a few quick stats:
Name: Yuki (who is definitely NOT the girl in the pic on the website)
Looks: 6.5/10 (coquettishly cute)
Body: 7.0/10 (about 1.6m tall, est B-cuppers, average build)
BJ: N/A (did not get one, as she offered but said she didn't like to do it and I do not like knowing that I was making someone do something she didn't like)
AR: No BJ, you expect AR?

FJ: 6.0/10 (not too responsive, one position only)
Damage: 170 inclusive of room.
RTF: Duh, whaddaya think??!! Prob not even gonna use this 'agency' again, let alone RTF the same gal... unless I see reports from reputable sources saying they've had positive experiences and are getting what they see on the site.
