A special release fulfilling the desire to tie up schoolgirls, put collars on them, and torment them. Ami and Hikaru are caught in mischievous play while still in their uniforms inside a locker room. With collars around their necks and their hands bound, they're left in their bloomers and subjected to unexpected treatment, their resistance gradually fading away. Though initially reluctant, both girls slowly begin to melt, their adorable moans growing louder as they become increasingly wet. The highlight comes when thick vibrators are thrust in and out of them, their bodies unable to resist any longer.
