Straight up massage or am I doing something wrong?

Okay so there is an AMP that in a short distance to my home in a strip mall, not in a great area but not really a bad area either, has been open for about a year. I found the place in December and have been visiting once a month for 4 months, they call me by name so I'm obviously a semi regular now. I use the same woman each time, she speaks little English, or so it seems and is probably mid 30's and Asian. The place is ran by a younger Asian guy who runs the front desk and speaks decent English with a heavy accent and all I see working there are other women and none of them speak English. The place is pay after the fact and I heard them tell a guy once he needed to tip if the girl did a good job after the guy stiffed her, its 60.00 for an one hour massage and 90.00 for an hour and a half, sign out front says BODY MASSAGE and the place has the typical Asian massage parlor name. There are not any reviews on this place other than Google and Yelp, this is the norm for my area, people do not share information once they find a good spot because the do not want it to get shut down, the cops are diligent here.

So there is the back story, today was my 4th visit with the same woman, pretty much the same massage each visit, today things went a little further. Completely naked, 50 bucks laying on the table every time, she has no problems with roaming hands an any location, she does a combo, hand over warm towels, hot oil and stone, with the oil she teases a ton while you are on your back, no area doesn't get grazed or touched more than once. I smile, tell her she looks pretty today, she pretends to blush, on the flip she uses a small sheet and massages you through that, pressing and probing all around the best spots, afterwards a kiss on the cheek and a hug from her and she leaves.

Today was very sensual, more time in the usual spots, money still on the table, she took every chance to look at my junk and smile so when she was massaging right up high on the innner thigh she asked if it feels good, I tell her it feels amazing and to not stop, she smiles and keeps on going, but never offering anything else, I finally ask her if I can do it and she says yes, then looks towards the door and makes the shush sign while she keeps massaging me there. She moves to a different spot still working on the same places and when I reach for my business she pushes my hand away and whispers "You come back tomorrow". I'm pretty sure the "you come back tomorrow" Is just to get my money and nothing else is going to happen, I tip her 20 bucks regardless as I was trying to let them know I was here for business.

So am I doing something wrong? I have been told a ton all of my life I look like a cop, whatever a cop looks like, or have I just stumbled across a highly sensual normal massage, and a damn good massage too.
