A very, very weird situation

After a few minutes when Jenny and I stay quiet, I ask my best friend:

"Is his mother still at the window?"

"It is very simple to discover. Crawl to your laptop and see if she's on the screen."

I do that, and I'm a little relieved by what I see:

"She closed the curtains!"

But the quick relief lasts only a few seconds when I hear my dad's voice echo like thunder from below:

"IVY, COME HERE NOW!"

"What do I do?", I look at Jenny.

"You better not keep him waiting!"

"But I need to get dressed!" I'm just wearing panties and topless.

"No, go like this! It will give more credibility to the story that you were dressing but you forgot the curtains open. And remember: you have to be innocent and sorry all the time!"

"But I..."

Before I can complete the sentence, my best friend pushes me towards the stairs...

"I'll be here, if you need me.", Jenny whispers. "And put your hands on your breasts, for God's sake!"

When I realize, I'm already in front of my dad, mom and the teenager's mother in minimal clothes!

"But what does that mean...?", My dad's eyes widen and he loses his words.

My mom remains static, while the woman shows a proud smile:

"Didn't I say? This girl was trying to tease my son, and now she appears like this in front of us... what a regret for your parents!"

"Oh, I'm sorry, it was all my fault!", I say the way Jenny taught me. "I always close the curtains when I get dressed, but I got distracted and forgot. I apologize to everyone. This will never happen again, I promise!"

My parents seem to believe in my "sincerity" and look at the teenager's mother. The woman continues to stare at me. I smile shyly at her as I continue to cover my breasts with my hands and feel my nipples swell.

"Bullshit, I don't believe a word of what this girl said! Don't you see that she is trying to trick us?"

So my parents look at me and I can't think of anything else but to join my hands, like someone who is going to pray, and say:

"I'm not trying to trick you, I swear!"

It takes me a while to realize that they are not looking at my hands, but my...

"Of course she had to show her little pink things again...", says the teenager's mother, looking disgusted. "And now, what are you going to do with your pervy daughter?"

"Hey, I'm not a perv..."

Then my mom pulls me by the arm to the couch, puts me on her legs and starts to... slap my ass! What a shame! Right in front of my dad and that woman! And as if that weren't enough, she pulls my panties down and slaps my naked buttocks willingly! I'm so ashamed that I can't say anything but moan. 'Damn, why didn't Jenny come to help me?', I think. The bastard must be enjoying my homemade humiliation...

When she gets tired of hitting me, she tells me to put on my panties and be grounded in the bedroom. I try to argue that I'm no longer a child, but my mom gives me a furious look. Before I go to my room, feeling my buttocks burning, I still look at the teenager's mother...

"I hope you learned your lesson, girl!" Says the woman, smiling and proud.
