OYC-085 Sister's Video Camera Captures a Wild Stayover Party

The narrator's sister, who works as an AD at an AV maker, asked to borrow his video camera for a stayover party, and when he lent it to her, he found far more explicit footage than expected. The party included not only her female friends but also male friends who brought their younger sisters, all adults, and they ended up undressing and getting excited together. Since it was a group of men and women of an age interested in sex, things got out of hand, and there was no shortage of dirty acts on record. He then decided to release the footage as an AV without permission.
