It may be a trip to the park, but this is not going to be very pleasant for you. You will ask passers-by if they will punish you for being a pervert. I don't care how humiliating it is! Now we have found someone, he is going to give you a long, hard spanking on your bare bottom for everybody to see. Oh the shame of it! You may think it is over when the spanking is finished, but I have some more humiliation for you. You will thank the gentleman with a blow-job. Go on, suck on it and take it nice and deep in your mouth!
Unfortunately for you, the whole process gives you an erection. You are a disgrace! Just for that you can relieve yourself in front of passers-by to show what a filthy little pervert you are. What a humiliating day at the park for you!
