There are some
AMPs that will do it. However most will not and do not like women coming in, as you can often hear what is going on in the next room and women may take exception to those services and report them.
You need to talk to the provider and
mamasan 1st, and schedule it. If you are a long time client they may allow you to bring in a gf. However most of the girls I know are not into giving another girl a
HE, they may watch you provide it, and most will be scared to do anything to you while she watches. Fear of you breaking up and she reporting them later is high.
You need to set your expectations with the
mamasan and a provider, if they ok it then have fun, otherwise, find a private
incall/outcall person to service you.
