Get you to pay the extra $40 because you might be afraid you'll miss something you want. Opinions vary, and practices among the different agencies may, too. Some say it's CIM, others say it's msog. One agency told me directly that msog was covered in their basic rate. But another agency may not. Pretty sure Greek is not included at either level.

I was wondering the same time.  I am always afraid of asking over the phone since you aren't supposed to mention sex.  My guess is rimming or MSOG.  I have just been doing the GFE and rimming hasn't been part of the routine.  I know it is not anal.  Usually the girls don't have a problem with CIM with just the GFE.

But I think MSOG is the main thing about the plus option. Also sometimes I noticed  a girl seemed to be more active during the whole session from start to finish with the plus option  as oppose to having more stoppage time or calling it quit early with non plus option.
