Beth can't take this anymore, you said you had to go. She hops out, wandering around the car. You hear her coming but are just finishing peeing. Just ad she comes around behind you, you finish, zip your pants up quickly and spin around.
"What are you doing?" she stares are you.
You scramble, "oh just fixing my pants, weren't on quite right". A good vague lie, hopefully she doesn't inquire more.
"Oh yeah, were you trying to fix the wet spot on the front of your pants, and what is that behind you," she leans by you seeing the puddle. Obviously standing out due to today being quite dry. "Did you piss in public??" she gets very close.
"I'm so so so so sorry Beth, I just had to go, didn't want to make a mess, no one saw me," you stammer.
"Oh, I'll show you what it really means to be sorry," she grabs your wrist, opening up the back doors of the G-wagon and pushing you inside. She climbs in after you, pulling down your pants. You don't have time to react until they are down. She sits on a seat, "over my lap!" She grabs you pulls your bare butt onto her lap, facing her. Notably, she leaves the door you entering in open, your butt facing it. "Kids who misbehave must be punished," with that she starts smack smack smack smack smack smack. A steady rhythm she plays on your butt. Each successive one hurts a bit more. After about 10, she stops for a moment, "we are going to count to 30 together, if you move, I'll do more". SMACK "one", SMACK "two". She is hitting harder than before, but stay stay still, quietly counting along. SMACK "three", SMACK "four", SMACK "five". You brace as they really sting Eventually you get to the end, SMACK "thirty".
"Now, stay still," she begins rubbing your bottom, massaging the tender muscle. "I'm going to give you a few options for punishment, since you just showed you struggle to control your bladder. First, I spank you 50 more times right now, and daily for the next four days. Then, so long as you have no more accidents, we can forget the entire thing. Second option, you agree to wear diapers 24/7 for the next five days. During day time, I'll let you use washroom, but at night the washroom will be locked. I'll change you, any accidents increase the duration. Spankings stop now if you choose that option, so long as you behave. Final option, I teach a home economics class to young adults, normally 19 year old girls. They need practice changing diapers, and other things. If you agree, for the next five evenings, for five hours each night, you will accompany me to the class where the girls will practice on you. During such time which you must use the diapers like a baby. And if you think you can just hold it during this time, I'll be giving you lots of liquids and other assistance to make sure you use them. So, what will it be?'
