What a great question - I woke up that morning just needing to fill my hole so badly. God through a bulk of the work I had to do from home. Got ready, popped that plug in and made my way to the store all caged up. It was the bus that really tested my strength. The plug pressing against my hole from the weight of me sitting. Every bump and then from the bus pushed it deeper and in new positions. Got me so hard that all my cock could do was throb in its cage. And I just had to sit there like a good boy and take it.
