I've always been a bit of a dirty girl. I like to piss my panties whenever I can and even better, I love to watch a hot sexy girl lose control and pee inside her clothes. This is exactly what happened to me last summer, when I was 18.

I was on a night out with a group of friends. I was already really horny because before I had gone out I'd taken a shower, making sure I was desperate for a pee before I got in. It turned me on so much to step away from the shower and let my piss go, running down the insides of my legs until I felt myself cum with pleasure.
When we arrived at the bus stop Sophie was there, looking gorgeous and sexy. Her wonderful full breasts were pushing to escape from her strappy top and her blue jeans clung to her perfect ass. She was always really flirty with me so when she came over she gave me a little friendly kiss on the mouth, and since I was already so turned on I couldn't help slipping my tongue in. She smiled back and went to sit on the backseat of the bus.

I knew I wanted some wet fun later that night so I kept drinking from a huge bottle of water. I made sure I offered it to Sophie and she too drank. I couldn't help imagining her bent over sexy and desperate, trying not to wet her panties

By the time we got to the club I was starting to feel a bit tingly down there, and that got a lot more obvious after 3 beers. After a lot of practice I'm pretty good at holding my pee so I knew I had a while to go before I would have to let it go but no rush as I would be with Sophie for most of the night. We danced together the whole time, our stomachs and breasts moving close to each other and we shimmied up and down. Every time she pressed against me tightly I could feel my bladder squirm with both pleasure and a growing desperation. This was all turning me on way too much, and with all I'd been drinking I was growing more and more horny. Sophie kept buying us both drinks, so many I truly lost count, but I was still sober enough to know I was quickly getting nearer to having to pee so I yelled in her ear over the loud music, "I'm gonna have to go pee honey, I'm desperate here!" My plan was to get out of my skintight black trousers and pee my panties on the toilet so no one would know yet I would feel nice and extra wet. There was a massive line for the ladies and by time I was next I could feel myself losing control; all those beers were taking their toll! I got inside the cubicle and tore off my trousers but as I did a spurt of pee splashed out onto the floor. I grabbed my wet crotch to hold on a bit longer but felt a trickle of pee seeping through my black panties. I couldn't even sit down in time so I just stood above the toilet legs open, and let go, peeing so hard and fast through the cotton. It felt so good that I just couldn't stop no matter how hard I squeezed my muscles. I came suddenly at the intense pleasure and then managed to stop peeing because I wanted to hold some for later.

I left the toilets feeling somewhat relieved but like I could have surely peed some more. I had to still concentrate on holding it as it felt like it was right about to exit my pee hole. Sophie came up to me and pushed another drink into my hand and we carried on dancing for what must have been a couple of more hours and several more drinks! When we looked at our watches we realized we had the last late night bus to catch and only 10 minutes to get across town and get on it! I was sure we'd never make it.

We ran out of the club but it's hard to get anywhere fast in heels, plus I noticed Sophie was tottering more than usual. I asked if she was ok and she just nodded. By the time we hit the park, which was about halfway across town, the bus must have been getting ready to set off. It was at that point Sophie stopped dead.

"I know this is the wrong time, but I'm dying for a piss," she said, with a look of panic in her eyes. "I wanted to go before we left the club there was no time."

"Well," I said, "to be honest, I think we've just missed our bus darling, so we can go back if you want and get a taxi."

"But we'll have to pay to get in again, and then we can't afford a ride. And to be honest...I don't know if I can make it all the way back there! I have to pee so bad I think I'm already a little wet."

She looked really upset now, sweating slightly, her 2 hands pressed to her crotch and legs crossed over on top of them. She was slightly bent over, swaying back and forth trying to stop the need to pee. It was JUST like my fantasy and I felt myself growing hot and horny. I reached into my bag and finished off the last of my water bottle so I could feel my bladder pressing against my waistband. I was already wet but it wasn't only pee...

"O my God, I don't think I can hold it any longer. What am I going to do?" she squealed in desperation.

"Don't worry Soph, it's OK! Just let it go. I honestly don't mind and I promise I won't tell anyone."

"I can't," she protested, "It's too embarrassing! Anyway, I don't think I can, I've never done it before."

So I told her. All about my fetish and about how I peed in the shower before coming out, how I wet myself in the ladies and how I thought I was about to now again.

"Arggh all that talking about peeing is making it worse!" she cried. " I can't hold it...O my God...help!"

I moved over to her just in time to see a dark stain seep through her jeans. She pressed desperately against the mark and managed to control herself again. But slowly I took her hand and moved it away.

"Just let it go, you'll feel so much better, and it's REALLY turning me on!" I said. She giggled and let me take her hand away. She was still trying to fight it, though. But she couldn't. Once again I watched her pee, as it poured down her legs soaking her jeans. I moved in closer and felt the warm wetness seeping into the denim. She was breathing fast as she let go, a final gush spilling out and running off my palm.

It was only then I felt the same warmth spreading between my legs. Laughing, I eased down my jeans, led her hand down to my wet crotch, and let her feel my hot stream as I peed myself again. I couldn't stop, and I could see that she was really turned on too. She pulled into me, my pee wetting both of our already soaking legs and as we kissed I came in an explosion of pleasure.
