Awesome, watching porn in public without caring about getting a boner, isn't it?
Now I need you to find a toilet and get into it.
When you're in a cabin, shut the door, but don't lock it up!
Now get naked and put the stack of your clothing between your spread legs!
Hands on your head and lock to the door for the next 2 Minutes - set a timer on your phone.
When the timer is up you may lock the door and unlock your cage ;)
I want you to jerk with a minimum speed of two strokes per minute, no accidents allowed.
If you edge you may stop for a maximum of 30 seconds before jerking again

I hope you're not edging too much, as all your precum will dribble on your clothing *evil laugh*
