I had been wearing these leggings, with no panties for days - just sweating and stinking them up. I knew I wanted to make my slave take my equally dirty ass in them before I put them in the wash. So I set up a session where he had to take my smelly ass in these soft black leggings for 5 minutes straight - no letting him up for air. The smell was almost completely unbearable, and even as he started tapping and screaming near the end - I ignored him and carried on sitting my giant ass on his face. Lucky for him, it was only 5 minutes.
