Any sub such as myself will of course be grateful to be used in the clever way illustrated in this film. I hope I can be of service in this way to anyone in London UK or due to visit for work or holiday. I'm pleased to say I'm about to take delivery of the same pussy mouth gag to facilitate the use of me like that
A very good question you ask. I'd love to know also as I'd like to be used as a throat pussy too and the device inserted into the sub's mouth looks like the icing on the cake of the mouth opening devices i currently use when a superior would like to use me in this way.
