Quickly identify the collar

As Yvette started casting the identify spell on the now clearly magical collar, she reached up her hands in the cramped space to touch it. As she did, she felt the boob bands constrict and bulge out her large breasts painfully, the pain was increased by the spiky clamps dug into her skin, and tears welled up in her eyes. Despite this, her pussy started leaking juices as the magic of the bands turned her on immensely. "HMmm" The sorcerer girl moaned as she cast the identify spell.

Cobaltite Collar of Constriction
This collar is made from Cobaltite metal that senses the arousal of its wearer, should the wearer get close to orgasm, the collar wil constrict painfully and **** the wearer. This collar is used by kobolds to stop their captives from orgasming too much. When the wearer passes out before reaching climax, the collar will grow on the wearer, eventually turning into a full posture collar and gag.

"What the fuck?!" Yvette shouted out as the spell notified her of the evil item. "I can't take this one off either?!" She slowly started realizing the huge mistake her and Megan had made entering this awful dungeon. She couldn't help but worry about her sister, helpless at the whims of the kobolds that made the exact item she was wearing right now. Determined to save her, she pressed on.
