When we got out of the shower, I made something to eat for us. I asked Sue if there was anything that she wanted to do in the afternoon. She said that she would like us to go swimming. I had not been in a pool for years, but agreed, and we started to look out our swimming stuff, and I got out a couple of towels for us.

We were almost ready to leave, when the phone rang, thinking it might be Mum or Dad I answered it. It was Jes, she asked if I was busy, I told her that I was about to take Sue swimming at the local pool. She asked it I would mind taking the twins with me, she said that they had wanted to go swimming again, that they had wanted to go to their usual pool, but was sure that they would not mind going somewhere different. I heard her call to them, and she then said to me that they said it would be ok. She asked when we were going, and I told her that we had just been about to leave when she phoned. She told me that they would be ready in about 20 minutes. I hung up and told Sue what was happening, she did not look too pleased, but I told her I would get us some chips later, she seemed better about it all now.

We waited for about 10 mins, then went out to the car, I decided to take the Jag, since I was taking the twins too, now, and we set off to collect them. When we got to the house, they were ready and waiting for us. Jes told me that Joe wanted to see me. I went into the house and met him. I asked if everything was ok, he said everything was fine, he just wanted to thank me for bringing Michelle's swimming gear back, and that it not been neccessary, she could have survived without it, and asked if I could possibly work all week, as Jes had a couple of appointments tomorrow. I said that it would be ok. He then gave me £100 cash, and said that this would cover today and tomorrow. I said thank you, and went back out to the car.

We set off, and got to the sports centre 15 minutes later. I parked the car and we all went in. The girls headed off to to their changing room, and Michael and I went to ours. I  went into a cubicle and changed quickly, I was joined at the way to the pool by him a few minutes later. While we were walking to the pool, he asked if I thought that Michelle was pretty, I said that I thought she was, he then said do you think I am too, after all we identical twins, I just laughed at this, but wondered why he said this. We got into the water, it was a lot cooler than I had expected, nut it was ok. The girls were not in the pool yet, so I swam to the farside and waited there so I could see them when they came in, Michael swam over and joined me. 

The pool was almost empty of people, there were a group of pensioners taking swimming lessons, and a small group of girls and boys who were about 10-14. I saw Sue first, She looked really pretty in her silver one piece suit, then I saw Michelle, she too was wearing a one piece today, it was bright yellow, she looked great too. They saw us and jumped into the water and swam over to join us. We all swam around for about 10 mins. I decided that I would see if my diving was still reasonable, and went to the diving board. I was not as good as I used to be. Sue said she could not dive, so she did not even try it. Michelle said she would give it a go, She pulled herself out of the water, she had a really nicely shaped bum. She walked to the board and got ready to dive. Sue, Micheal and I were all opposite her, we were going to judge her. It was then that I noticed that her swimsuit had gone almost transparent when it was wet, I could see her nipples, and could see the shaddow of her dark pubes. I could feel myself getting hard just looking at her. She dived into the pool, it was not great, but it was better than my attempt. Michael said he would have a go. He ducked under the water and swan to the other side of the pool. The 3 of us were now together, Michelle(Cel) next to me, Sue about 3 feet away, Cel asked if she had done well , I told her she had, she said did I took good, I told her that she had. My hair was drying out so I ducked my head under the water to soak it, also to have a look at her body again, this time close up, her swimsuit was see through, I cold almost see the texture of her nipples, and could see her pubes clearly, it got me hard right away. I came out of the water, and tried to rearrange myself, just as Michael (Mik), pulled himself out of the water. His bum was almost identical to his sisters.

I did not know at this point, but found out later, that when he got to the otherside of the pool, he had ducked his head under the water at the same time as I had, and that he had seen me looking at his sister, and he had seen the effect that it had on me. He got onto the diving board, and I could see that he his cock was semi hard. H must have realised this too, as he quickly dived into the pool. It was a spectacular failure, and he seemed stunned, so I swam over to him, grabbed him and swam to the side. I asked if he was ok, he said he was, but had not been concentrating properly, (it was the he told me what he had seen), as he had been thinking about what he had just witnessed between me and Cel. I really did not know what to say, but he said not to worry, as she had the same effect on him. We swam back to join the girls. They both asked if he was ok, he said he was. I asked Sue if she was ok, she said she was a little bit cold, so we all went swimming again to warm ourselves up. I could tell that the girls were still feeling cold as I could see that they both had hard nipples.

I noticed that Mik had also seen this, and could see that he was trying to rearrange himself, I ducked my head under the water, and saw that he was quite hard by now, I also looked towards the girls, Cel looked really sexy, and Sue was trying to rearrange her swimsuit between her legs, so I swam underwater, and did it for her, having a feel of her pussy as I did so, causing me to become totally hard. I then swam back to the others. I saw that Mik was underwater and had seen what I had just done. He had seen that I was now hard, and I could see that he was too. We came up, and turned to the girls, I could see they were still cold, so suggested that we got out and went for a coffee to heat us up. The girls got out of the water, I said I just wanted to do another couple of lenghts first, Mik said he would do the same. The reason I said this was to allow time to try to lose my erection. After a few mins it had gone down enough so I could get out of the water. 

Mik and I made our way back to the changing rooms, we were the only 2 in there. We got our stuff out of our lockers, and went into the cubicles. We went into cubicles facing each other, they were about 4 feet apart. I took off my trunks, and saw that I was semi hard, so started to rub myself thinking about what I had seen of Cel, Mik then asked if I had liked looking at his sister, I could see through a gap in the curtain that he was stroking his cock, I told him I thought she was pretty. He wrapped a towe loosly around himself and opened his curtain a bit to talk to me, he must have seen what I was doing, as he asked if he could watch. I told him to come over then. He came in beside me, and we closed the curtain. As I continued to rub myself I could see under his towel he was getting harder too. I told him to put his towel down. Now we were facing each other about 12" apart, both naked, both HARD. I was about 7.5" in lenght, and about 2" in diameter, he was about 6" length and just over 1" in diameter. 

 I asked him if he thought about his sister much in a sexual way, he said sometimes, I asked if he had seen her naked, he told me that there was a door between their bedrooms, and sometimes if it was open a bit, he could see her gerring changed, as he told me this, he started to wank, and I started to wank too, watching him was really turning me on. He asked if I had seen Sue naked, I told him that I had showered her when she had hurt her wrist, he started wanking harder and I could see him watching me wank. Mik then asked if I had ever done anything with a boy or man, I told him I had a few times. He asked what it felt like to touch another cock, I told him that it felt good, I could see pre cum oozing from the tip of hic cock, mine was totally covered by now. I asked if he wanted to touch mine, he reached over and started to wank me, while he wanked his own too. He told me if felt really nice, and asked if I liked what he was doing, I told him it was great. He asked if I wanted to wank him, I reached over and started to wank him too, it was a great feeling, I could tell that he was really horny, he was leaking a lot by now, I asked him to let me know before he came, he said ok. He asked if I had any tissues or anything, I told him dont worry about it.

I sensed that he was about to cum, I asked him if he was, so I asked if he would like me to suck him till he came, he said yes, so I got on my knees, and took his hard slippery cock into my mouth, I had been sucking him for about 2 mins, when he said..and he came in my mouth, there was not a lot of it but I swallowed it all. I then stood up and started to finish myself off, he asked if he could do it for me, and started to wank me hard, I could feel that it would not be long. Mik then leaned forward and down and started to lock my slippery cock, it was great, he then took the tip of my cock between his lips and licked me. I told him that I was going to cum, he pulled back a bit, but continued to lick me, I came all over his face, mouth and neck, he licked some of it off his lips and swallowed it. He was about to wipe the rest off, I told him I would do it, and I licked all my own cum off him, I was about to swallow it when he asked if he could have some of it, and leaned forward to kiss me, (I had only ever kissed one guy before and that was my mate when I was about 15), it was a proper french kiss, he licked most of my cum out of my mouth. I then swallowed what he had left, and he swallowed it to. By now we were both stcky, so we went into the showers, both naked, and then got dressed and went to join the girls.

We went for a coffee, then I took the twins home. They both said thank you as they got out of the car, and said that they hoped that we could do it again sometime. 

As we were driving home, Sue said she had something to tell me when we got home, but would not say anythine else, apart from thank you for taking her, as it had been a lot of fun.
