Sweet 18

M y sister turned 18 recently. I am much older than her, 40. I live by myself and she would visit sometimes. About a year ago she started to spend a night on weekends. Since last year i notice how attractive she is. I blank it out of my mind. She would sleep in another room. When this year started, i began to be closer to her. She always dress very sexy. I would go in her room and give her a little kiss and a hug. She started to come in my room before she goes to sleep to say good night. I would see her in her night clothes. That would cause me sleepless nights. I told her to spend her 18th birthday by me. She said ok. On friday evening she spend a lot of time on the phone and watching TV. She had on a very short pants. I would look at her all evening without making it look like i was looking at her. In the night, she went to bed. On saturday after she had breakfast and a shower, she came in my room. I was on my computer. She sat on me. I was surprised. It felt very good. She had on a very short skirt and a short T-shirt. Her legs were soft and smooth and sexy. My hand was on her legs. I said happy birthday and gave her a gift. And i gave her a little kiss on her mouth. She hug me and said she love the gift. She was getting up and i said you have to take a drink today. She said no, but i still gave her a few and she took it. I went back to the computer, hoping she come back and sit on me. She did. She said, what you doing. I said watching girls. She said, can i see. I said, sure. I put my hand on her legs. I said, you see how beautiful women take out their clothes and look nice. She looked at me and smiled. I then pass my hand slowly up her legs. I was almost touching her panty but i did not want to frighten her. I left my hand in one place for a while. She was talking and ignore my hand. I then reach with my fingers and touch her panty. When i try to hold it , she left.She then went on the phone to chat with her friends. When it was night and she was having a shower to go to bed, i put a spider on her bed. She is afraid of spiders. She ran out of the room and told me that she was not sleeping in that room because it have a spider. I said why don't you sleep with me tonight, i will protect you from the spider. She said ok, thanks. I went on my bed waiting for her. She came in with a T-shirt and a long pants. I said you cant sleep with that, where is your night clothes. I went in her room and got it for her. She went in the wash room and put it on. She came back looking very sexy. I can see her red panty. I said lets take a drink and play cards on the bed.  When we was playing, i began to touch her. I saw she like it. I put her to lie down and started to kiss her. She was a little drunk. I said that i love her. I then started to kiss her legs. She said, what you doing. I then pull out her panty. She said no. I started to suck her *****. She resisted a little, but then give in. I was holding her down. I enjoyed sucking her. She is so sweet. I then put her legs over my shoulders and push my **** inside her ****. I ****** her. It was so good! She had pain of joy. She started to cry and said, you are my brother. I said its ok, brothers and sisters **** all the time. I said, you have a good time. She said, yes. We went to sleep. The next morning, she had a shower and was getting ready to leave. I told her that last night was special to me and i will like to do it again. She said, this is ******. I said no, only if we make a baby, then it will be ******. I held her hands and said, I am your brother, i love you and would not do anything to hurt you. I lift her up and put her on the bed. I passed my hand on her legs and started to pull down her panty. She put her hands to stop me. I said i will buy anything you want. She said she want a car. I said ok, i will buy it for you. She, then moved her hands. I pull out her panty and started to finger her ****. She got hot. I put her on top. I had my hands under her to move her up and down. My sister **** was moving up and down my ****. I was ******* her and having a  really good time.
