Despair at my classmate's birthday party

[Mary Moon 1,958]

I don't think i've told this story yet: it basically happened a few years ago when i had just finished middle school. At the time i wasn't very popular and had few friends. Anyway, i was invited to this party and decided to go, since i wanted to look cute because there was a boy i liked at the party, i put on a dress with a skirt (quite rare for me at the time) and consequently i didn't wear a pullover because the bulge would have been noticeable (in hindsight it was a mistake). Basically i had a nice day for once, even the girls who usually made fun of me a bit, weren't mean. Basically i was feeling so good that day that I was caught off guard by my usual sudden desperation because i stupidly hadn't emptied my bladder after two hours like my mom always told me to. So i ran to the bathroom immediately only to find that there was basically a couple inside doing dirty things in there. I panicked because i felt like i wouldn't be able to last much longer. To make matters worse, the boy i liked was there and watching me, and he probably realized my desperate state. I knocked but those two in the bathroom ignored me. Desperate i went to find my best friend and explained the situation to her, telling her that i was about to wet myself again in front of everyone, so she took me out into the garden near a shed at the back and said that I could do it there, i said that i was afraid of being seen and she asked me "would you prefer to wet yourself?", then i couldn't resist any longer, i pulled down my panties and pulled up my skirt finally starting to pee, while my friend kept watch. In the end, very relieved, i went back to the party
