Smothering The Helpless Worm

Ive strapped the slave in the restrain bondage bag and now hes fully defenseless and at my grace! I sit down on top of him and embark smothering him with my hands - then I get off his body and put my knee on his throat while still smothering his nose and mouth with my hand. Then I take a plastic bag out of my pocket and the slave begs for mercy immediately - but there wont be mercy! I sit down on him again and put the plastic bag over his head to smother him! He starts to struggle immediately and clearly panics as his oxygen levels drop! Then I decide to put some more pressure on his throat and smother him with my hands again!
