My sister Kate

I'm David 24 single and live with my twin sister Kate, we both live in the city away from family. I've always been a the party guy and Kate the shy bookworm. But on arriving in the city together a few months back, it was a bit overpowering for us both at first. I soon got use to the ways of the city, but Kate was Kate she kept going at her own pace and nothing would change that. Anyway last month there was a big thunder storm and it shook our building and you would have thought there was a battle going on outside. I don't like thunderstorms, but Kate is really scared of them and as a child would hide in a closet and or under a bed from them. But would also go to our parents bed, but as she got older she was told to stay in her bed. But she would join me in mine and cuddle close to me, I was out when the storm started and when I got back to our apartment, I had to look for Kate she was in the bathtub under a blanket shaking. I took me a couple of minutes to get her out of the bathtub. She stayed so close, it was like we were joined together. I didn't mind her being close and sat watching TV and her almost on my lap. With storm still raging outside, I needed to go to the toilet and she came with me. After I was finished she wanted to use it also and had hold of my arm and wouldn't let go. I even had to help her get panties down so she could use it. She wouldn't let go of my arm, then after helping pull up her panties. I decided I would turn in and go to sleep, it was only 830 on a Friday night. Nothing worth watching on the TV and I wasn't going anywhere in that storm. I told Kate I was going to bed and I brushed my teeth and she done hers, still holding my arm. I drop my pants a and removed my shirt 1 sleeve at a time, she grab my other arm to let me remove it. I said I would sleep naked, she got into bed with me still dressed as she was. I laid down trying to get comfortable with Kate cuddling up to me, I was laying there with Kate cuddling me and started thinking sexual thoughts and got a hard on. I just laid wishing it would go down and not touching it, then there was big flash outside the window and a very large crash of thunder that made the building shake. Kate moved on top of me grabbing me as hard as she could. I don't know if she felt my hard on straight away or had after she had relaxed a bit. But I think it was poking her in her groin area. A little later she moved one of her hands down and touched it, on feeling her touch it. I said If go to your own bed now I can take care of that. She wouldn't move and I said It is uncomfortable and I want to take care of. Still not wanting to be alone she said I could put it between her and get it off that way. I answered It would to dry and I would some lube. She reach over to my side table grabbing some skin cream I had there and said She would spread it between her legs and that would give lube enough to get myself off. She pulled her skirt up and spread the cream between her legs below her panties. Then she guided my cock between her legs and told me To go for it. She held her legs tightly together and I started pumping my cock between them. As I went for it I grabbed both cheeks of her butt and pulled her closer to me. I came just as another thunder clap went off nearby. My sperm went all over her legs and panties, but still she stayed close. Feeling cheeky I asked her The next time I need to get off, are up for another like this one. She didn't reply and the storm seemed to had pasted, she finally got off me and went to have a bath. I had enjoyed her letting me blow my load between her legs, I was just about to roll over went there was another clap of thunder another storm cell was coming thru. Kate was still in the bathroom drying her self and came running and jump into bed with me again. This time she was totally naked and she wasn't going to get out of bed to put any cloths on. Having Kate totally naked cuddling up to me, was to much for my cock and it stood up to attention again. I asked her Would she let me get off again between her legs as before. She looked at me saying Can't you control yourself, I answered Normally I could but having a good looking woman hugging me close and totally naked as well is more than I can handle at the moment. Alright she said, but the cream wasn't on the side table and then she remember taking it with her to bathroom. Not wanting to leave the bed either, she said She would suck and pull me off. Thinking that would be great at first, but then I realised the danger and said No way, if there's any more thunder claps you'll bite my cock off. So let me up and I get the cream. No your not leaving me she said, Come with me then I replied. Another No she felt save in the bed, I said if don't let me get the cream, I'll just have to fuck you. Expecting her to tell me Get the cream. But she just said Well fuck me then I not leaving the bed for anything. So I had sex with Kate and I fucked her again in the morning, even after the all the storms were gone. Every time I'm near her now, I feel her up and she doesn't complain. Then last night I was feeling randy and asked her Straight out for a fuck. She said Okay and we slept together again, I want to have even more sex with Kate now.
