Its time that Elise Graves wants to push herself.

Dart_Tech was happy to help and got her strapped down in the tight bondage chair with a gas mask on. He hooks it up to an electric valve and then to a foot-switch and places it under her foot.

Elise has to hold her foot down on the foot-switch to keep the air going. This is complicated by being tickled and vibrated though many breathing, and non-breathing orgasms. Its complicated even more due to the valve taking 3 seconds to fully open or close.

A bubbler bottle is used to help show when shes breathing.

How hard can she push herself?
