Eating restrictions

The next morning you are awoken by an uproar. Your mother seemed to be in a heated argument with your sister about something. Upon closer listening, you can make out the words, "addicted" and "disappointed".

Your mother clearly enraged slams a door and the argument seems to be over. After a while, you get up and head downstairs. You ask your mother what that ruckus was about. Apparently, your mother has found a hidden candy stash from your sister. And with sugar being the **** of the 21st century your mother is not happy and tries to convince your sister to watch her sugar consumption.

Later that day your mother catches your sister sneaking candy into her room, which was the last straw and your mother snapped. The next morning your sister woke up with a chastity belt around her lower half. Now she could only eat when her mother unlocked her.

The next could of days your sister got increasingly grumpy due to the sugar withdrawal. Eventually, your weeping sister reached out to you for help. Unsure what to do you agree to help and you both set out to figure out how to get your sister her sugar fix.

The first order of business was to obtain the key from your mother, which wouldn't be easy, and then make a copy or feed her with sugar while the belt is unlocked. Mother kept the key hidden so your sister wouldn't find it but maybe you could extract that information from her.

Maybe you could try to lockpick the lock after a LockpickingLawyer video but that would become very tedious very quickly.

A few days later your plan has matured and you are ready to call your mother, staging an emergency while she is at work to get her to tell you where she was hiding the key.

After you explained to your mother a made-up reason why your sister needed to take some very important pills, she reluctantly told you that she hid the key in the fridge next to the vegetables. A fitting spot against a sugar addict. You retrieve the key and head to your sister.

She is super happy about the key and you present her the genius plan of what you are going to do. You present her with a medium-sized jawbreaker. That hard sugar candy should be enough to keep her cunt dissolving for a while.

You kneel between her legs and unlock the chastity belt. Her cunt is already dripping wet in anticipation. You drag the jawbreaker up and down her slit, leaving a sticky sugary trail on the orb. Then you push it in as far as it would go. Your sister lets out a painful yelp as the big orb enters her but that is soon followed by a sigh of relief as her cunt tasted the sugar. While she is in the ecstasy of the sugar you quickly stuff another jawbreaker into her and finally another. Your sister is now in a panic because she is now filled to the brim with sugar and her cunt was quite significantly stretched with only two jawbreakers but you quickly buckle the chastity belt again, locking the candy inside of her.

"Why did you put three in there big brother?", she asked confused and a little frightened. "I feel so full and it hurts to move around with so much inside of me."

"Better not let it show what we did today little sis", you reply and leave her to hide the key again.

A while later you meet your sister on the way to the toilet and she looks pained, with a hand holding her lower stomach. Seems like her cunt is painfully stretched around the jawbreakers which causes her cunt to cramp and cause discomfort.

You also spot a trail of her fluids running down her leg, probably from the heightened drool production and the fact that her cuntlips are not able to close around the three massive jawbreakers in her greedy hole.
