Have you seen the state I feel my trainers? They're disgusting! Covered in dirt. How do you expect me to go out looking like this? I thought I'd trained you better than that.

Let me take my trainers up and gag you with my sweaty sock whilst you inhale into my trainer and wank over my sweaty feet...
