Oh I see you are talking about the girls who are not prostitute? You paid those students to have sex with u?
Well, if girls in shop have day off. Will they come to you for just an hour? You should get free sex and bring them around.
If girls come to your house during workimg days then tthat is outcall. There is no way girls will ask their pimps for like 2 or 3 hours break and come to your place......
