Wednesday was back to school for a Computer Science exam. Mum had decided to take another day off of work, so Erica and I got an extra dose of dad’s morning pee on our school skirts. The sofa felt so wet and warm as dad’s stream seemed to go on forever. We sat for an extra minute to let the excess pee soak away before we went to the dining room for breakfast.
As before we peed just enough down our legs to feel the warmth before we crossed the road to go in to school.
We went in to the exam hall, and then realised that there were not very many of us doing computer science, there were only six tables set up. We sat down in our allotted seats and I just resigned myself that I was going to pee during the exam at some point, and that it would be probably be quite obvious. At least I was sitting next to Erica again so could easily see what she was getting up to.
As soon as I sat down I got comfortable and let out a small spurt to wet the back of my skirt. Being resigned to being discovered I did not hold back and made quite a loud hissing noise, but the brevity meant that no one noticed. The warmth soaking under me was nice while I wrote my name on the top of my answer paper.
We had yet another new invigilator, which was good because if I got caught wetting myself I would be able to bluff it out again. I felt a little more relaxed.
I worked through the paper methodically and was pretty much done by about half time. I thought about wetting myself blatantly, just peeing full blast and letting my pee splatter on the floor, and then excusing myself from the hall for the rest of the exam, but in the end I decided to just tuck my legs under and pee gently and discreetly while I checked my answers.
I looked over to where Erica was sitting, and could see her slowly expanding puddle. Our minds were thinking alike again.
I had triple checked my answers when the time was up, and I took my paper up to the front quickly, closely followed by Erica who managed to splash her foot in my puddle as she walked by my desk.
It was a nice sunny day so we walked home, as we did not want to wait for the usual bus. It was nice having my wet skirt brushing the back of my legs until it dried in the sun.
Back home we went up to our room. Mum had tidied it, and changed our bed. We put our school stuff away tidily for a change and went down to have lunch with mum.
While we ate mum explained that we would all be going to the station to meet Colin as soon as dad got home, he was going to come home a little early so we could meet Colin’s train.
After lunch mum sent us back upstairs to make ourselves look nice for when we met Colin.
We sat at our dressing tables and made a special effort to make our hair and faces glamourous. I suggested to Erica that we keep our school uniforms on because we have already wet our skirts, and we could wet them again and see if our pheromones would make Colin like us.
Erica said. “I’m going to wet my skirt again now, it should be dry by the time dad gets home.”
Erica peed hard and I could hear her peeing, and hear her pee running on to the carpet under her stool. I peed too. We carried on prissying ourselves.
It seemed like no time at all had passed when I heard dad come home. I stood up and felt the back of my skirt, and fortunately it was just damp. We went downstairs.
Mum said. “Just time for a cup of tea, then we will have to go.”
We sat in the lounge and drunk tea while mum told us. “We should welcome Colin and be on our best behaviour. Colin won’t be here for long and we need to make a good impression.”
We nodded approvingly, wondering how complicated it could be just having our brother come to stay.
Tea consumed we all piled in to the car and dad set off for the station.
Erica whispered to me. “It would be handy if we could just wet ourselves in the car, it is only ever us in the back, I don’t think anyone would notice.”
I reminded her in an equally low whisper. “Colin will be in the back with us in a minute, he will know...”
Mum heard us whispering. “Don’t be shy, tell us all...” She said.
I said. “We were just wondering what Colin will be like now we get to meet him at last.”
Mum closed the argument. “There is no need for speculation, we will see him in a few minutes.”
Erica whispered to me again. “I’m going to let some run down my legs when we see Colin.”
I whispered. “Me too.”
Mum said. “That’s enough.”
Erica said. “I think Colin will be cool.”
Mum said. “Good.”
Nothing more was said until we got to the station.
We all piled out and dad checked the arrival board. Colin’s train was on time so we made our way to the platform gate and waited. Dad was standing one side of mum and Erica and I stood the other side.
We saw Colin’s train coming in from a distance, and when it finally stopped we scanned the mass of people to see if we could recognise Colin. It was not easy having not brought a picture, and anyway he would not be wearing glasses.
Erica and I were caught by surprise as a smart boy approached dad and gave him a hug. The internet picture was very deceptive, and must have been quite old.
Dad introduced Colin first to Mum, and then to ‘The Twins’, which I guess is how he has been referring to us.
Colin shook my hand in a very formal way, and I informally started to let some pee run down my legs. I did not take my gaze away from Colin’s face, and did not stop peeing, until he let go of my hand.
As Colin shook hands with Erica I glanced down at her legs, and like me she peed a little, making a very small puddle on the terrazzo floor around her feet.
We all went back to the car. Dad was chatting with Colin as we walked about his mum. Mum got in the back of the car with Erica and I so that Colin could get in the front and talk to dad. They talked about Colin’s exams, how he was getting on with English, history and sociology.
By the time we got home it was nearly time for tea. Erica and I went upstairs for a few minutes to freshen up before dinner, and we both stood and peed down our legs while we checked our appearance in the mirrors, letting our pee soak away in to our carpet until we were empty.
We discussed Colin’s merits, mainly that he looked a lot better than we expected, and that he had picked some super boring A-levels that we would have trouble making conversation with him.
Mum called us back downstairs for dinner.
We had dinner, and then coffee, and it went on for ages as mum interrogated Colin.
Mum very kindly wheedled out that Colin does not have a girlfriend, that Colin really enjoys school and is looking forward to doing sociology at university, that Colin plays chess, that Colin has pet newts, and that Colin likes to do archaeology. In fact Colin likes archaeology ad nauseum.
After what seemed like ten hours, Erica and I had not spoken, dad had spoken little, and Colin had spoken at length about the bronze age. We had consumed a glass of wine each and it was ten O-clock and mum suggested that we sort out the sleeping arrangements.
Mum said. “Astrid and Erica, since you have the biggest bed Colin can sleep with you. I am sure you can find room for your brother. I don’t think the sofa will be suitable for our guest, it is not in very good condition.”
I was a little shocked. The sofa was not in good condition because dad has been pissing on it (well, Erica and I have pissed on it too, but that is not the point.) Our bed was not in much better condition, but I guess that is why mum had changed the sheets.
Mum told Colin. “Get your case, and the girls will show you up.”
Erica led the way upstairs, and Colin dragged his case up behind me.
Erica spoke to Colin. “The bathroom is this way, you can put your pyjamas on in there if you like.”
Erica led Colin in to the bathroom and cleared some space in the cabinet. “You can put your things in here.” She said.
Colin said in a slightly feeble voice. “I don’t wear pyjamas.”
Erica just said. “We are cool with that.” and left Colin in the bathroom.
Normally at bedtime we would take off our makeup, but having Colin in with us I just wanted to stay looking beautiful and not natural.
Colin came back out of the bathroom and opened his case. He took out his bathroom things and returned to the bathroom.
I took the opportunity to quickly undress and put on my nighty. Erica did the same and we climbed in to bed.
Colin eventually returned from the bathroom carrying his clothes strategically in front of him.
Colin spoke falteringly. “Your mum said I will have to sleep in your bed.”
Erica answered. “Yes, that’s right.”
Erica lifted the cover on her side. “You can climb over me and sleep in the middle.” She said.
Colin put his clothes down, and now could not hide the slightly exited state of his dick. He quickly ran over to Erica’s side of the bed and climbed over her and lay on his back in the middle of our bed, his dick now making a tent of the cover.
Mum must have heard that it had all gone quiet and she came up. “Are you all ready for Horlicks?” She asked.
Erica and I nodded.
“And you Colin?” Mum asked. Adding. “We all drink Horlicks at bedtime.”
“Yes please.” Said Colin.
Mum went away and we just laid there on our backs, not really knowing what to say.
I broke the ice. “We had better sit up so we can drink our Horlicks.”
We all sat up, Colin seemed very relieved we could not see the tent anymore.
Mum brought in our Horlicks. She stayed while we drunk it, and then took the mugs away and turned off the light.
I slid down into bed and stayed lying on my back, Colin wriggled down too, as did Erica.
Mum said we must be good, so I thought I had better let Colin know. “Colin, I hope you don’t mind, but we wet the bed.”
Colin said nothing.
I heard hissing from Erica, so I relaxed and started to pee full blast, and continued until I was empty.
Colin spoke falteringly. “I thought you meant you sometimes have accidents.”
Erica answered. “No, we never have accidents.”
I turned on my side facing away from Colin.
“You can cuddle me Colin if you like.” I said.
Erica said. “And I will cuddle you.”
Colin turned and I felt his still hard dick between my buttocks. I wriggled so that it pressed against my slit. It felt nice. Colin put his arm over me.
Colin started to move his dick back and forth, I could feel the head flicking my clitoris. I adjusted my position so it slid deeper in to my slit.
Colin continued, and cupped my breast in his hand.
I adjusted my position again, and Colin shoved his dick in hard.
Colin suddenly erupted with energy. He was like an uncaged beast thrusting in to the hilt, like a jackhammer he thrust in hard, banging me up the bed.
As quickly as he had started in just over a minute it was over. He gasped and with one final thrust he started to throb inside me, pumping me full of his cum.
Lying there in a warm wet bed with a dick shoved inside me and cum oozing out I was in heaven.
Colin rolled on to his back with a sigh. I just laid there savouring the wetness, and the sticky cum.
Erica said. “You can cuddle me now Colin.”
Colin laid there for a minute before he rolled over and cuddled Erica. I felt Colin move and then Erica gasped, and Colin was off again, thrusting in to Erica.
Colin’s stamina was building. It was nearly five minutes before I felt him thrust in to Erica as he started to cum and Erica started to whimper as she too orgasmed.
I rolled over and cuddled Colin, and we all lay like that until I fell asleep, feeling very content.
I was soon awoken though as Colin once again started thrusting in to Erica. This time it was Erica who came first, her whimpering building as Colin continued his regular and fast rhythm. Erica got louder, her orgasm ongoing and building as Colin kept up his impressive performance for a couple of minutes until he came again.
Colin turned on to his back so I turned over and faced away. We must have gone to sleep again.
I was again awoken, this time Colin was thrusting in me. I guess I woke up straight away, but I was thinking he was being a bit cheeky waking me up like that, but I was a bit groggy and soon started to enjoy it. He was relentless and I was so wet from before that there was little friction. He kept going and I touched myself and that tipped me over the edge and I started to orgasm. I relaxed my bladder and could feel my pee spurting in time with my orgasm, and in time with Colin’s thrusts. Colin continued and my pee stopped, my bladder was emptied earlier. My orgasm built and I could not help gasping, getting louder until Colin finally thrust really deep almost shoving me out of bed and then pumping his cum inside me.
Colin rolled on to his back, and I stayed on my side curled up, loving the gooey wetness around my crotch almost down to my knees.
