For one week only, an erotic panty shop opened on Shibuya's Dogenzaka. Lured by advertisements promising easy cash, schoolgirls came to sell their used panties, only to be tricked into performing explicit acts on camera. What started with handjob and blowjob scenes quickly escalated to full intercourse. The camera captured the schoolgirls' increasingly lewd behavior, spiraling deeper and deeper without restraint.
