If you're in the search of the perfect accessory for exciting BDSM play, then this Cheek Retractor Gag from Master Series could just be what you're looking for.
It effectively holds the mouth of the submissive open, so that you can get in without any hinder. Be it for a blowjob or simply to stop excessive talking.
A kinky alternative to the more traditional gags, but undoubtedly more humilliating for the submissive, but still titillating for you both.
The gag clamp is light and inserts in the mouth and then expands so that the lips can't move and the mouth is kept open. One-size and comfortable to wear.
