My Sister? My Mistress? - Di, where's my pants?

Hi guys, it's been a few months since I post here. I'm really busy with my schedule... I've decide to put "The fantasy story" to a pause first, I will definitely go back to the story and end it. For now let's continue with a new story.  

I'm Glen a teenager in local neighborhood school, not any of those branded schools with really good reputation. Back in my primary school days I got really bad results as compared to both my sisters, Amanda my eldest sister age 18 she's currently studying in a local junior collage; I've another younger sister age 12 she's currently studying in a top primary school in Singapore. I failed my PSLE resulting in me getting into the Normal Technical stream, I'm weak at my academic failing almost all my subjects. My parents has gave up hope on me since secondary 2, they cancel all my tuition class after realising that I might not even score well to get into ITE.

I had a girlfriend with me but we broke up after I got caught masturbating with her thongs, I got this bad habit soon after my sister got into JC. Back then JC girls all wear FBT shorts for their PE lessons, I use to steal my sister FBT shorts to masturbate. I stop stealing her shorts after I got caught by my younger sister while stealing the shorts. I pay her money to keep the secret for me, it was not long before I got caught again this time round for stealing my mother's thongs.

Amanda: Di what are you doing with mum thongs?!

Me: Er... Jie... Er...

Amanda: Those FBT's?!

Me: Jie listen listen... Shh... jie!!! Shh!!! Please don't!! I promise I'll do anything you want!

Amanda: *Stare* You sure?

Me: Yes Yes!!! Please anything!!! anything you want!

Amanda: Where's all my FBT shorts?

Me: Is... in... my room... I!!! I'll!! return them all to you, now! now!

Amanda: No! (Jie stop me from moving)

Amanda: How many of them have you take?

Me: 3... a curve red shorts without netting, and 2 curve black shorts with netting

Amanda: Come to my room tonight after Pa Ma is asleep, wear nothing but the red FBT shorts.

Me: Huh?! Jie... it's Xs... I... cannot...

Amanda: Think about it, 12am will be your deadline. *Snatching away the thongs*

Amanda: *holding on to the thongs* If I don't see you by 12am this will be in Ma room.

Amanda: Di... you have 8 more hours for you to slowly consider.

What will Jie do to me? What will it happen to me? Jie broke up with her boyfriend 2 years ago, back then they broke up because her boyfriend cheated on her and she has not have any boyfriend after that.

*Beep*
(Whatsapp message)
Pa: I will be on a oversea visit till next week, mum will be accompanying me. You 3 please take care of yourself. Especially Amanda, please take care of your Di and Mei.

Oh no, this week will definitely be a terrible week for me!!

Amanda: I believe you have receive Pa message. Mei is having her school holiday and I've allow her to leave over at her friends house for a week.

Me: Er... Jie... I agree to...

Amanda: So how should be be dress like?

Me: Er... Jie I'll change in my room.

Amanda: No do it here

I've no choice, I've no say... She's the queen. Striping down my pants and boxers, I change into the small size FBT shorts. It's really small and I can hardly fit inside with my fully grown penis I can hardly hide it inside the shorts.

Amanda: I want a slave

Me: No problem Jie! I can do all your laundry, Cook your meals.

Amanda: No... No... not only these.

Me: Erm... What else do you want Jie, tell me and I'll do it!

Amanda: Take a look at this video

*Handing over her iPad*
It's a short 30 seconds video a naked man was seen with his penis lock and a woman whipping him using a cane. A collar was also attach onto his neck with and mouth gag.

Amanda: This is what I want.

Me: Erm... Jie... I'm really sorry but... is this necessary?

Amanda: Yes! Give me your answer now yes or no.

*Taking out her phone.*

Amanda: 3... 2...

Me: Okay okay! Jie I... promise.

Amanda: Alright di, from now on you will address me as Mistress when no one is around. When no one is at home, you will not be allow to wear cloths, if someone is around you can only wear the shorts you steal from me.

Me: Yes Jie...

Amanda: *Slap* What?! Say again!

Me: Sorry... Yes Mistress

Amanda: *Slap* Yes and you're still wearing your pants.

Striping down the only piece of cloths with me, I pass Jie my pants.

Amanda: From today, your body belongs to me. No masturbation, no touching of your body without me. Understand.

Me: Yes mistress.

Amanda: I want your private parts to be clean. *Passing me a shaver*

I've a habit of shaving my private parts back then when I'm in swimming team, but I've stop the habit after I left the swimming team. But this's the first time that i'm doing this in front of someone else and the person is my sister!
