This is a position I can hold for a long time except when my feet start falling resting. Out of the giant ball in my mouth, the clovers hanging from my nipples and my hair being tightly knotted and holding myself in place, the one thing that always gets me are my feet. Having to stand in heels with all the pressure of my body weight resting in these shoes always does the job. Lucky for me, I didn't tap out this time :D
