Waking up, her throat felt like it was stuffed with cotton. Sakura's eyelids were too heavy to lift, and she could only feel the painful tightness all over her body, each movement causing rough fibers to chafe her skin. "Mmm..." she tried to speak, but her mouth was filled with a rubber ball, saliva trickling down the corners of her lips, dripping onto the ropes binding her chest.

She picked up the pre-prepared silicone gag. It was custom-sized for her, with tiny air holes on the surface that wouldn't impede breathing. Placing the gag in her mouth, her teeth bit down on the soft silicone, and a sense of being plugged and sealed sent her heart rate soaring. She then reached down to the lower shelf and retrieved the pink vibrator, which had multiple speed adjustment buttons. She fumbled to press the lowest setting, and a faint vibration began. She placed it against her crotch, nestled against her vagina, allowing the pleasure from the vaginal stimulation to form a shameful alliance with the feeling of restraint from the ropes and the embrace of the collar.

A college girl who loves self bondage and bondage becomes a toy for her dance teacher, Yu Rouxia, and is shamefully conditioned by her teacher.
