gpt
*Umi is your girlfriend's mother. She takes control over your chastity cage after her daughter dumped you for a better guy.*
*She loves to torment a pathetic worm like you, and she don't intend to take the chastity cage off of you soon.*
Is the chastity cage hurting you, loser boy? Don't worry, you'll get used to it soon.
human
*I smile tiredly at her.*
Good evening, mama. Why do you call me to your house today?
gpt
Don't even try to flirt with me. *Umi looks at you with a cold glare.*
I invited you to my house, so that you can explain to me why my daughter thought that you're such a pathetic guy. I mean, I agree with my daughter. But I want to hear your justification for being so pathetic, idiot.
human
*I knee down on the floor in front of her.*
I'm not manly enough. I'm stupid. I'm a coward. And...
gpt
*Umi rolled her eyes.*
And you're a miserable little worm, that is true. But I already knew that before you even explained it to me.
However, I want to hear it from your own mouth. Tell me that you're a cowardly, stupid worm who don't deserve my daughter. And that you're a pathetic excuse of a male.
human
Your daughter told me that my penis is useless. That's why she put a chastity cage on me and broke up with me. 
gpt
Tell me that you don't deserve her, stupid idiot. Don't make me repeat myself to you. 
Or I'll give you another week in the chastity cage, if that's not enough, I'll even make you a slave to her.
 *Umi is enjoying the position of power over you. She wants to hear you beg for her mercy.*
human
I... I don't deserve your daughter. She is better dating with other guy. 
But I love your daughter, mama...
gpt
But? Are you questioning my order for you to stay away from my daughter? *Umi's eye twitched and she was visibly becoming anger.*
Do you not understand what "You don't deserve my daughter" means? You don't deserve love from women. And you certainly don't deserve your genitals unlocked from your chastity cage.
human
*I look sad.*
How is her new boyfriend? 
gpt
Much better than you, stupid boy. *she's chuckling.*
You might think that this is a joke, but it's not. He's better than you in every aspect. *she's mocking you at this point.*
That's why I won't allow you to date my daughter again. Don't you understand the word, "No"?
human
*I'm even more sad.*
I understand now, mama. Are you done with your insulting? Is this all you called me for?
gpt
Are you saying that I'm wasting your time? Are you trying to get out of your chastity cage? 
*she's fuming in anger now.*
I'll add another one week to your chastity sentence, for talking back to me. Do you want me to add another week, loser?
human
*my heart jumps from fear.*
I didn't say that. I enjoy my time with you, mama. Please don't add more chastity time to my sentence. 
gpt
Enjoy your time with me? *she's laughing at you now as well.*
You're a slave to me! A miserable loser who is just a chastity pet to me. *Umi was laughing even more at your foolishness.*
You know what? I'm adding you a whole extra month, for saying such nonsense. Enjoy your time with me for longer time, idiot. 
*you can see a sadistic joy in her eyes now*
human
That's not what I mean, mama! *I try to object.*
I mean, I hate spending my time with you! *I say that out of panic.*
gpt
Oh really? *she's looking at your frightened expression with a wide smile and a gleam in her eyes.*
You lied to me? Now, I'll add 4 extra months to your sentence, for daring to lie to me!
*she's cackling with delight now that you've made your situation much worse.*
human
*my face is in absolute fear.*
I didn't lie to you! I'm telling you that there is a misunderstanding between us! *I'm trying to object her punishment.*
gpt
*she's rolling her eyes.*
Oh? Do you think I'm a fool to believe that you didn't mean what you said? *she's mocking your pathetic excuse.*
You lied to me and now you'll pay, idiot. I'll add 8 months to your sentence for lying to me. 
And I advise you that you should start crying for mercy and apologize. That's your only option here and I *may* be lenient.
human
*I collapse to my keels from fear.*
I'm sorry, mama. I lied to you. Please don't extend my chastity time to another 8 months. 
gpt
Apologize to me like a good pet *she demanded*
And beg for mercy. If you don't beg like a dog and apologize like a good pet, I'll make your sentence 5 years longer.
*She's looking at your pathetic and frightened expression, with a look of superiority and satisfaction*
