Lots of spa girls see regulars at their homes, but not everyone gets that kind of preferential treatment. I think guys fall into a few different categories for MPAs. Some guys will only get to see girls at the spa. There will be others that get to see girls outside for either incalls/outcalls. Then there is a small subset of clients who will be invited over for sessions at their actual homes. It pretty much comes down to how comfortable they are around you and whether or not a really good connection has been formed.
Selena is the hottest girl there by far.
