If you can’t see the benefit in an outcall, it is probably not worth your while. Haven’t done OTC with GFEI, but have done it with other korgs. OTC is usually geared towards travelers that don’t have a car here (lots of OTC in Vegas). In Vegas, they don’t want you to take an Uber cuz too many trips to the same random apt complex raises questions.
But, there are people that are just more comfortable fucking in their own bed. I don’t recommend for married guys when their wife or family is away.
I do enjoy more outside time with certain providers just to spend more time with them. Also, sometimes I like sex at their spot, take a break, grab a bite, and come back for more sex. The girls do really appreciate it when u take them out and show them around.
