i decided to have some fun the other night and see how long I could hold my pee. I started by about 8pm already feeling a slight urge to pee but I ignored it and carried on watching tv and drinking juice . At 10pm I had to go downstairs and help design a poster , so I was sat with the night staff and one of my flatmates drinking tea and getting this poster finished by 11:30 I was really getting desperate so I tried making my excuses to come back to my room but they seemed insistent on stopping me every time I went to walk out the room by 12 midnight I had had enough and was so desperate to pee it hurt I had every intention of just going upstairs to my flat and going to the toilet . By the time I was halfway up the stairs I had to shove my hand in between my legs to try hold it in . I got my my front door and just managed to get it open and get inside before I started to feel myself loosing it. Before I could run to the toilet I had to unlock my room door and put some stuff I was carrying down so I would have both hands totally free to quickly pull my skirt up and my leggings and panties down . I got my door unlocked and as soon as I did I lost control I quickly went inside my room and shut my door as soon as my door was closed I started to piss myself full force I couldn't do anything other that stand there legs pushed together bent over at the waist as I totally soaked my clothes and the floor. Needless to say I was so horny afterwards I changed into a clean pair of white panties I knew it would not be long until I needed to pee again cause or the amount of tea I had drunk, so I lay in bed masturbating through my white panties till I was desperate to pee again this time I grabbed my phone and filmed myself loosing it and pissing my panties in the middle of my room. I then had one of the most amazing orgasms ever and went to sleep
