SRPD-001 - I want to bully schoolgirls! 1

This is a work for those of you who want to tie up high school girls, put a collar on them, and bully them all the time. Ami-chan and Hikaru-chan get pranked in the locker room while wearing their uniforms. A collar was placed on her, her hands were restrained, and she was dressed in bloomers and made to behave in various ways. The two of them hated it at first, but gradually they started to get excited and let out cute moans. She got so wet that she didn't mind having a thick vibrator inserted inside her.
