This story happened about a year ago, I have a younger sister (she’s around 1 year younger than me)
Since we were young we would tickle each other, this eventually evolved into tying each other and seeing if we could get free.
Normally I was the one tying her up as I was still able to overpower her
So one day our parents decided to meet our uncle again (we met him a lot of times that month and were pretty bored as there wasn’t much to do at his place, so we decided to stay home that day), I went in my room, exited as I finally got a chance to tie myself up again. I wanted to try a new belt tie method I found online, I put my hands behind my back and made the belt tie. I started to pull it with my teeth being careful not to pull it too tight. The thing is that it somehow got stuck, so I pulled with all my force (which is pretty hard to do with your teeth when your hands are behind your back lol) and suddenly it got unstuck and I pulled it way to tight. Panicking I tried to free myself with non success. I laid there struggling for 15 minutes.
I heard my sister yell “Hey! You want some spaghetti?”. I was too embarrassed to yell back, which was a big mistake. She came upstairs, in a hurry I tried to crawl under my blanket, but - too late. My sister giggled “Well what went wrong here”. “Stfu” I replied. She giggled again and said “Now it’s my turn. She ran out of my room and came back moment later. She stuffed some sock in my mouth and taped it shut after. She then tied my ankles with another rope and then tied my arms to my waist with some tape.
Right next to my bed was a TV, she then turned it on and started searching for a bunch of random stuff on YouTube, messing up my algorithm. I tried to break out but the belt gave me no chance to try to wiggle free. After some time she got bored and just turned on Netflix.
Fast forward some time she looked at me with a smile on her face. She pulled of my socks, I squirmed and tried to pull away but she held me by my ankles.
She started tickling my feet, I squirmed and laughed (as much as it was possible under the sock), it was probably just about a minute but it felt like hours. After that she went downstairs, just telling me “Imma make my spaghetti’s now”.
I first tried to break free but quickly gave up, I just decided to enjoy being tied up. I laid there in a way of embarrassment of being tied up by my much weaker sister, but also enjoying it. I knew I had no chance of escaping unless my younger sister freed me.
When my younger sister finally came back she laid my feet on her legs and started telling me about her interests. She picked the ones I cared the least about. I gave her an annoyed look, which just made her enjoy it more. Whenever I looked away or she felt like I wasn’t listening she would tickle my feet.
After some time she then freed me.
I suck at writing so I hope you guys like it
I think you write quite well. Stories don't have to be magnum opuses written in iambic pentameter 
I'm sure I'm not in the minority if I say that short and sweet stories are the best.
Love to be tied-up
