Endurance test - what's your limit, seat pad?

Description: I brought my phone to stop the time you're able to hold your breath under my ass! i sit down on your face right away - and since i want to test and push your limits, i'll not only smother you for a long time, but also only let you breathe very shortly before i sit down again! and i think, every time i'm going to sit down, i'm going to stay sitting a little longer than before! you know you've no mercy to expect from your mistress, right? being my seat isn't easy - and it's not supposed to be easy! so, what's going to be your limit? a minute? one and a half? 2 minutes? even longer? we'll see!
