Lots of people ask about it. Very few people would actually book such a service considering the added cost of an extra masseuse.
And between you and me while the happy ending might be spectacular, seeing two lovely pair of boobs ... sorry, pair of hands , the actual massage part (if you like a good one), can't be better than the massage one person provides since it's very hard to co-ordinate symmetrical / same pressure movements from 2 different masseuses.
