This is my first story. This really happened in my life and it is the first time I have told this story.

My BIG HORSECOCK and my two older sisters.

It all started when I was 10 years old. I grew up in a large family but I was closest to my two older sisters, their names are Julie who was 20 years old with massive tits and Lana who was 18 years old and huge double D tits. I had a big cock for a ten tear old boy at about 6 inches long and very thick. I loved to jerk off at night thinking of my two well hung sisters. I shared a room with Julie and Lana shared a room with my other brother because Lana and Julie used to fight all the time so Mum separated them. I didnt mind as I used to go to bed early and perv on my big titted sister when she came in and got naked ready for bed, I used to love full moons as it gave me a great view of her shaved cunt and oversized melons. I was in constant state of horsecock hardness.

It all started when Julie was afraid of the lightning outside one night and asked me to sleep in her bed to comfort her. I was embarrassed to say yes as I had a huge hard dick that wouldn’t go down but she insisted that I comfort her so I gave in and snuck over to get under the covers with her. I was naked and she slept in her see through nighty. She got such a shock when she cuddled up to me and felt my huge horsecock with her hand. She said “ oh my lord you’re big and hard down there” I said yes I am and it’s all because of you. She said “ why me, what have I done to make you so big and hard” I said its your big tits that make me jerk off my horsecock every night and day. She said “is that what you call this” as she slipped her hand around my thick cockshaft. Well it certainly belongs on a horse it’s that big. At that point my life was going to change forever. Julie then pulled the sheets back and slid down so she was kissing my swollen cockhead and then deepthroated my entire shaft. I nearly blew my load in to my big titted sisters mouth. She took her mouth off me long enough to say “ well arn’t you going to grope my huge tits, I know you want to, I see you staring at them all the time” I didn’t waste any time as I pinched her big nipples, she moaned around my horsecock and that was enough for me and I blew my first ever load of brother cum down my big titted sisters throat. Julie swallowed every last drop of brother cum and said” fuck your horsecock is tasty little bro, I’m going to have more of that. I was hard again in seconds and Julie insisted that I finger her hot cunt until she splashed her juice all over my hand. Julie and I spent the rest of the night tongue kissing and groping each other. I woke up the next morning with my head on her huge tits and she had her hand all over my horsecock that was hard again.She kissed me and slid down to suck me off again and told me she had to taste my horsecock cum again before she could stsrt the day. I was so happy to be looking at her tits as she deepthroated my shaft once more. I came with force down her throat again and she smiled and swallowed it all. She got up and gave my horsecock one last squeeze and then went for a shower. A week or so passed as me and Julie continued to play with each other, then it happened, everyone went out for the day and left Julie to look after me. We both new what was going to happen as soon as the car left the driveway I walked around the house naked jerking my hard horsecock and Julie was in our room stripping her clothes off ready for me to finally walk in and she insisted that she would love to watch me jerkoff for her and come in her mouth and over her huge tits but not today, today she wanted to FUCK and fuck right now. She layed down and spread her legs wide so I could see her hot wet cunt. She told me to lay down on top of her and kiss her large nipples and stick my big horsecock in to her wet cunt. I did just that. It was the best feeling in the world to be fucking my big titted sister because it was so taboo and naughty that it was such a turn on. I have never been so hard than when I am in up to my balls in my hot sisters cunt. She taught me how to please a slut. To this day I can always make any slut cum.
I shot my first of many more loads of brother cum up my big titted sisters cunt. I was in heaven and Julie was pretty satisfied too after cumming all over my huge dong. She wanted more before everyone came home so I was keen to shoot my next load all over her tits and face which I did about five minutes later.
I dont know what happened between Julie and Lana but over the coming weeks they became closer than ever, even friends. About a week later Lana asked me to play some cards with her in her bedroom. I was already in bed so I put some jocks on, I forgot that they were slightly see through. I went to her room and Lana was not yet dressed for bed so she said “come in” so I went in and sat on her bed where we usually play cards. She turned her back and proceeded to take her top and bra off.She said “ dont look will you” of course I looked, trying to sneak a peak at her big tits from the side. I saw a sneaky side tit and part of her large rubber hard nipple. My horsecock started to harden and I looked down and it was then I realised that my jocks were see through. It was too late to do anything about it now so I pretended to not notice. Of course she noticed the huge bulge straight away and I could see lust in her eyes. She said we should sit on the floor so I got up and walked over to where she was and sat on the floor. She never took her eyes off my huge horsecock bulge which stuck out obscenely. Lana smiled and looked me in the eyes. We sat down opposite each other and she crossed her legs as she sat which gave me a perfect view of her swollen shaven wet sister cunt. I nearly blew my load there and then. Lana noticed my horsecock pulsing and said as she delt the cards “do you like what you see” I said fuck yeah. She then said “ do you know your jocks are see through” I said yeah I do. Lana told me that I was big down there for a boy my age and I said yeah I very hard right now. She said “do my big tits make your horsecock hard” I said fuck yeah. I dropped the cards on the floor and slid my right hand up her flimsy cunt cover and gropped her large tit, she moaned gave me a full view of her hot wet sister cunt. I got the sudden urge to lean down and lick her wet slit. She moaned loudly and said “ yes yes lick my cunt baby bro” She tasted so good that I never wanted to stop tasting my slutty big titted sister. I am now 45 years old and to this day I have always fucked and sucked both of my big titted wet cunt sisters when ever we meet and as far as I know they dont know that I fuck the other one and have never mentioned it. When I am not fucking them I am stroking and jerking off to the memories of what taboo things we get up to. I have much pleasure in thinking I was responsible for creating an incest slutty family thanks to the size of my huge horsecock, by the way it no longer is 6 inches but a heafty 9 and a half strokin inches. I had my cockrings on and of course was jerking it off while remembering my sexy sister sessions with my two big titted sluts, my sisters.
