Самосвязывание кроссдрессер пошел не так

What was meant to be another routine self-bondage play session with my amazing neoprene sack with internal sleeves... It would go horribly wrong, when the string attached to the zipper pull came undone as soon as I managed to seal myself into the sack. Watch as I thrash against my stretchy prison, unable to free myself. I was eventually released when my roommate got home several hours later... Mortified isn't the word! Enjoy.
