Madame Marissa - Training his breath holding by facesitting

Ive put on a big stopwatch on the computer screen – and ordered the slave to be my office chair. And Ill stop the time he can hold his breath! And Ill not make it easy for him – Ive put on a very hard jeans that will surely flatten his nose. I think a minute shouldnt be a problem … or will it be? Well, well see – but Ill make sure the loser suffers under my ass – hell be mercilessly smothered and feel my full weight on his face! He doesnt really help himself by struggling that much – he just wastes so much oxygen … he should just keep calm … guess Ill need to train him longer! And I really dont like to be disturbed by his moaning – so I put on headphones and start some music – then smother him again and the timer starts once again! Unfortunately, I can still feel him struggling … so I guess next time Ive to bind him so he cant move and then put on the headphones!
