A sub secured to the chair and fitted with a gas mask.
Domina Araneae and Mistress Ellie are going to have a lot of fun.
They fit a bubbler to the mask to give for an interesting sensation to his breathing.
Very visually appealing watching the water bubble as he breathes.
Then adding a tremblr to his cock, this is going to be an intense experience.
As the intensity is turned up on the tremblr, it causes heavy breathing… but heavy breathing through the bubbler… is difficult
It gets increasingly intense, to the point the Dommes have little care nor concern on if he has cum, if he will cum or not – the reaction is enough.
