SDHS-038 【Special Customs Document】Bound Girl One-Box Delivery Helping Service Sakura Rika

I found a woman who independently runs a strange entertainment business on SNS. Her name is Rika (23), a simple-minded gal who looks like a caring older sister. Her job is running 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 reason for this and her work.
