Inhale The Jeans Fragrance

I had put my slave in a trummlesack. So he cannot fight back when I sit down on him. My jeansbutt fits perfect on his skull and the hard fabric streches tight above his mug! Thats how I like it! He only can breathe if I let him. And the only thing he smells then is my jeansbutt. I want him to inhale the hot jeans fragrance until it burns into his brain.
