Bad Day at School

It was a normal school day, all my friends were there. Because im apparently "underweight" the school pays for my meals free. Which is good but not great. So this one monday morning i had the cafe i had a full english breakfast, by the end of it i was so full, but i really liked it. This started a mini trend so i kept having these huge cafe meals at lunch and breakfast everyday. It was friday when i was sitting at a table with the guys i hang out with and a friend of mine handed me a cup of water from the dispenser, i thought nothing of it.

Then about 30 minutes after i had the drink, we were still at the table when i felt i really really HAD to poo. My tummy was groaning insanely and so i moaned to my friends "ohhhhhh, i have to poo!!!" I got up and ran to the nearest bathroom, they were out of order! So i waddled to the other side of the school and as i ran i felt some poo slipping out so i groaned some more. I found the bathroom and at this point i had my hands on my ass to stop the crap from rapidly coming out. I apparently had such a worried and scared look on my face according to my friends. When i sat on the toilet the ammount of gross gurgly noises i made was horrendous. I was farting continuously with all the poo. I heard some girls near the sinks saying "ewwww!" and then rushing out. I didn't really care, i had lossed all my dignity getting to the toilet anyway. I shouted "oh god, oh god, oh god!" as it was all still shoving out in a violent motion. As i put my knickers back on i realized that i made a mess in my panties anyway. I was thinking what made me poo so much, well i didnt crap in 5 days. But i was told by my best friend that some of my other friends played a prank on me and put laxatives in my drink!
