While I was playing on my cell phone on my bed, my older sister stormed into my room with handcuffs on. I knew she wanted to tie me up again. So I jumped up from my bed to defend myself, as it turned out, I was unsuccessful. She did a judo trick where she threw me on my bed. When I was lying on my stomach on the bed, my sister immediately jumped onto my back. I tried to get out of my helpless position. I tried to throw her down, but my sister stayed on my back. While my sister was sitting on my back I tried to throw her down. After a few seconds my hands were already tied, I hadn't seen this coming. Then my sister cuffed my feet. She then said to me: "I will probably always stay stronger than you." This sentence made me very angry, so I tried with all my might to escape. My sister saw this and wanted to prevent it. So she sat down in front of my feet and began to tickle them. I started laughing out loud right away because my feet are extremely ticklish. I also wiggled a lot to escape her long, red-painted nails. But I couldn't escape her fingers. She tickled me for 2 hours until she was tired and unleashed me. After that, I felt very weak and helpless. I had tried everything not to be tied up, but still it was no problem for her to tie me up.
