Bored

I'm Max 23 single live at home with my parents Amanda 45 and Ralph 49 and my sister Cybil 21 also single. I could say we're rich and the greatest looking sexist people alive, but the truth is we're average. Me and Cybil were home for Christmas and were bored, Amanda and Ralph had gone to see friends and would be gone most of the day. All our friends were off skiing or doing other things away from home. Cybil and me couldn't afford any of it and we were sitting home watching TV. I got some snacks from the pantry and Cybil tried get some and we ended up wrestling and tickling each other. During the wrestling Cybil's top came open showing me her breasts and I couldn't stop myself from touching them. She said Stop what do you think your doing. I replied Playing with your great tits. You shouldn't touch my breasts as your my brother. So I'm your brother and I like your tits I replied. Then I let go of her tits and she covered them up, at first there was silence and we just looked at each other. Cybil then asked me You really think my breast are good. I responded Good No, Fantastic is a better word and the best I've ever touched. Cybil was happy with that and we started to watch TV again. I kept looking over at her and she finally said What do you want. I want to suck your tits I answered. She You can't we're brother and sister. I tried to be funny saying No we're not I was adopted and we're not related. Rubbish I've seen your birth certificate and mine and we're brother and sister She responded. Pity we could have a lot fun I said. To which she said We can't have sex we're related. I said We don't have to fuck, just everything else short of fucking. Like masturbating together, no fucking. She didn't say anything and we sat watching TV. After about ten minutes or so, Cybil said This boring and I'll let you play with my breasts. If you will let play with your cock. I was taken aback at first, but soon agreed and we went off to my room as it was in front of the house and we would hear our parents return home. In my room I stripped off and then watched Cybil undress. We were soon on my bed naked and starting feel each other up. I went down on her breasts and then down to her vagina licking, fingering and sucking it. I soon had her all wet and moaning. After a bit she came and then she told me to lay on my back. Cybil then got on top of me in a Sixty nine position, as she licked and pulled and sucked my cock. I buried my face into her vagina. I came in her mouth and she swallowed it all, I stayed hard and after a bit of time I got on top of her and kissed her on her lips. At the same time I rubbed my cock along her vagina and then I found the hole and entered her. Asking her at the same time was she on the pill. Yes was the reply and I fucked her hard and blew my load inside her. After we laid together then showered together and were back watching TV when Amanda and Ralph got home. Thus started our sexual relationship and it still going today. We still date other people, but we keep each other happy as well.
