SDHS-038 [Special sex document] Restraint M girl one box delivery health

I found a woman who independently runs a strange entertainment business on SNS. Her name is Rika (23), a simple girl who looks like a caring older sister. Her job is to run a delivery health car. She puts on restraints herself and entertains customers with M play. Why is she doing this job? We spent two days closely covering the reasons behind this and what he does at work.
