You've once again found yourself tied down and helpless on a Tinder date. Sierra, looking down at you in her luscious leather boots, pink rubber gloves and 3M respirator is prepared to have her way with you. She starts off with making you breathe gas fumes before putting as gas mask on you. This one has a hose attached to a filter, but there's a catch: Sierra can cover the filter cutting off your airflow whenever and for however long she wants. She eventually starts to rub your cock while holding your filter against her breasts. This culminates in a countdown backwards from 10 that ends with you blowing your load all over her gas mask.
