me 13 ,breanne 11, and john SeXStoRY

I was 13 years old and I broke my right arm (the one i jerked off with).I had to go for physio therpy evrey day after school. After about a week I really wanted to jerk off but had no time to do it at home cause i shared a bed with my s****r 11 year old s****r breanne. My physio theripist always take 6-7 minutes before he sees me when im in one of his rooms so i tried to jerk off quickly before he started the session but I couldnt cum becuase I wasnt used to using my left hand. I heard him walking towards my room so i quickly covered my rock hard cock he came in and I was sitting on a bed with a t shirt and shorts on. my cock was hard and was almost perfectly defined while it was erect under my shorts. My physio theripist saw this and said "are you happy to see me" so i replied "yea but this sort of happend before you came in" he then asked me if i was right handed so I awnsered yea im right handed he then steped closer to me and kneeled down and said it must be very hard to relif yourself and asked if I wanted to take a break from regular exersizes on my arm. I happily said yes then the next thing I knew was that I felt a very moist kiss on my shorts. I saw him sucking on my shorts where my bonner was. After a couple minutes he pullled down my pre cum covered shotrs and started to suck my cock very carefully and slowly this sent shivers of pleasure up my spine. I had an urge to see his dick so i slowly took off his pants and was amazed when I saw his huge cock and I found myself starting to suck it. when a few minutes passed i blew my load all over his face. since I had not jerked off in a week my load was huge and at least half a cup of cum came out. when he ate my load he saw my skinny little ass and asked me if I wanted him to fuck me. seeing that i had 30 more minutes left in the session i said yea lets do it. before i knew what was happening his hard cock was rammed up my tender ass. As he did this my dick got hard again. a few minutes while he fucked me up the ass he finally saw that my little 13 year old dick was hard he began to stroke it. After 6 minutes of him fucking me and stroking me he said im going to cum soon do you want me to cum in your ass in you mouth or on your dick and I said try to do all three so he blew a huge squirt up my ass then quickly pulled out and blew the rest of his load on my 13 year old cock he then said sorry mikey I guess I didnt have enough to cum in your mouth i replied "dont worry about it watch this" i then stuck my finger up my tender ass and got all the cum i could find and mixed it with the cum on my dick and my pre cum that was squirting out of my dick then i stuck all that cum in my mouth and swallowed it. we then layed there naked starring at each other and fiddling with each others cocks untill we where stopped by a huge gasp and my 11 year old little s****rs voice saying what are you guys doing? john then whispered in my ear " do you want me and you to fuck your s****r?" my s****r was a very cute petite blond with blue eyes. i had been thinking about fucking her for a while so i eagerly replied "yes i really want to fuck her" so john my physio theripist said to my s****r "dont worry breanne i was just testing how strong your b*****r mikey's arm is" he showed her his dick and said " me and mikey have cocks this only gets hard when we get horny and when we are healthy". then my s****r took off her shirt and pants and exposed her small breats and her sweet little bald pussy and said "john whats this?" john then replied " thats a viagina do you want me and mikey to see if you are healthy? she asked "how?" and john replied we can only insert our cocks in you viagina and your ass if you are horny and healthy my s****r said are you going to do what i just saw you and mikey doing? john said only if you want us to. so my s****r said "please mikey can you test if im healthy?" so john explained to me that i needed to put my cock in her viagina and go in and out so i crwaled over to my s****r breanne and put my cock in her and did what john said. branne was moaning in pleasure and between each moan she said to john "john do you think im healthy" so john said we will only know if i can stick my cock up you ass she then gladly said yes so john tried to put his huge cock up her ass but it wouldnt fit so my s****r got really woriied that she was sick so john said i might be to horny lets see if mikey can fit his cock up your ass and if i can fit my cock up your vigina. Breanne agreed and soon enough me and john were fucking breanne hard and fast and after 13 minutes of this i blew my load in breanne's ass as she shook with an orgasim. john then said im going to cum again and asked " breanne do you want to share my load with your b*****r mikey in your mouth's we both said yes so he aimed his dick at our faces but his warm cum only made it into my mouth and my s****r was starting to say that she felt left out so i said ill still share it with you and french kissed her and pushed all the cum in my mouth to hers and she moaned in pleasure and said this tastes awesome!! then john told breanne that this way of checking if we are healthy is top secret and only will work if we only know about it so she said mikey i wont tell anyone if we can do it more offten so i said i promise me john and you will do this more offten. i looked at the clock and saw it was time to go so we all put our cloths on and since me and breanne still had some cum on our faces john snuck us out the window as me and breanne walked home she turned to me and said i want it to be just me and you that fuck from now on john wa th big and winked at me at that moment i knew that she wanted to fuck me to and knew what was going on so i said okay but next we will watch a video and we will try diffrent ways of fucking. then i thought how am i going to tell john that me and breanne didnt want to fuck with him and me and breanne just wanted to fuck by our selves.When the next day came I went to the physio therpist office thinking of what i was going to say.then john said to me that he doesnt want me him and breanne to fuck again. he said that me and breanne could fuck at home but he said he didnt know what came over him and he said he doesnt want to get fired. my s****r got her wish and i got to relif my self by letting my s****r suck me and by me fucking her peite little ass and vigina. plus me her have been fucking till i moved out when i was 18 if you want to hear more stories of me (mikey) and my s****r (breanne) fucking please comment on this story
