I have been wearing my slippers every single day in preparation for your session getting them as smelly & stinky as possible.
I know how weak & horny you get for them which is why I am not allowing you touch yourself until you have cleaned every bit of dirt & filth off of the bottom of them like a good boy.
Once you've earned it, I'll push that matted sweaty fabric down onto your nose letting you take a great big sniff. Then you need to worship every inch of the smelly slipper before I let you finally stroke & cum for them like my good little slipper boy.
