Introduction to brotherly love

My mother got the local babysitter to come and keep an eye on us as she had to go to a wedding no horny little k**s allowed, so she went as the young girl arrived to look after us. Both my brother and sister was out visiting a friend so I was there with her on my own, she informed me that she was horny and wanted to spend time away from me and encouraged me to watch TV. After about half an hour I started to hear strange noises coming from my bedroom so being an inquisitive young person I went to investigate on opening the door as quietly as I could I got quite a surprise. There she was naked from the waist down legs apart and two fingers in her wet cunt her eyes closed and muttering her brothers name, quite surprised all I could do was stand and watch as my little cock started to grow. As she opened her eyes and saw me standing there she told me to go and sit next to her and play with myself, I did what I was told and she carried on but after a few minutes she took hold of my cock and started wanking it. She apologized and told me she needed a man cock to fuck her dripping wet cunt and would be back in a few minutes, as she lived close she returned with her brother who was smiling from ear to ear, he started to ask me some horny questions like did I get hard watching his sister fingering herself to which I answered yes, had I seen a really nice man cock to which the answer was no. She laughed and said he would love to show me his, Whist taking her hand and rubbing his cock over his jeans I saw the big bulge appear and wondered how much bigger can it get. It was not to long before I found out he asked me to get mine out and as soon as he saw my young tiny cock he dropped to his knees and sucked the whole thing into his mouth she undid his jeans and pulled out his beautiful hard cock wow what a wonderful thing it was. For a young man he had the biggest thickest cock I had ever seen and with a little encouragement I reached out and held it as it grow even bigger. He explained that he wanted to cum so he was going to give his sister a good fuck she was already on my bed naked as the day she was born waiting for him, he told me to take hold of his cock and guide it into her wet cunt for him. My little cock was so hard I thought it would brake but I did as I was told and give him a few rubs before putting his cock in place for him to fuck her, she let out a sigh of relief and as he rode her wet cunt but before long she asked me to play with myself Whist sucking on her sweet tits I certainly didn't need a second invention I had dreamt of being in the position and jumped at the chance to suck her tits. Between the two of them I was asked to do a lot of nice things for her a finger up her ass for him play with his balls for me having my cock sucked by both of them. He explained to me he was going to cum but instead of filling her cunt he asked me to wank him off over her I jumped at the chance to wank his magnificent hard cock, as he took it out of her wet hole I took it upon myself to give his cock head a little suck just to see what it tasted like, he lost control and squit after squirt came over my face. His sweet sister was so happy to lick his hot sticky cum from my face. I had the opportunity to do this with them and they with me, each time was better than before she even sat on my cock and rubbed her cum filled cunt over my cock and face l learned a lot of wonderful things in the threesums we had. Eventually I grow to love them both and grow up with their unique outlook for sex. I have even put into practice what they tought me back then sex is forfilling with anyone willing to take part.
