My Friends Little Sisters

When i was a teenager, maybe 13 or 14, i had a friend down the street. His name was Jason, and he was a few years older than me. He turned me on to all kinds of stuff. Ciggarettes, weed, porn... all the stuff 16 or so year olds in our neighborhood were into.
One day we were sitting at his house and he pushed a vhs tape into the vcr, saying "check this out."
The tv lit up, and there was a woman getting fucked from behind on the screen. We watched for a few minutes until he heard his mom moving around, so he turned it off and we went outside.
A few months later, Jason got arrested for breaking into a house. He got sent off to juvy, and i was stuck with nobody but his sisters to hang out with. Their mom didnt think anything of it, so i was there just about every day.
One day, we were all sitting on the couch in the living room. We had been watching tv, but Amber, the youngest of the 2 sisters. Started talking about wanting to go to their room, so we all got up and went. When we got back there, the older of the two ,Brandy, started looking for a movie to watch. After a minute or so, i thought about it and said, "i know what we can watch." Then i got up and went to Jason's room, and ejected the tape from the vcr and returned to the girls.
I walked back into their room and shut the door behind me. Slid the tape into the vcr, and turned down the tv so you could barely hear it, then pressed play. The picture came up, and there was a red headed woman sucking on a dude's dick.
Both girls were like, "oh my god! What is this?!?" I didnt know either, so i just told them to watch. We sat there, one of them on either side of me, watching as she sucked his dick then she layed down and he started eating her out.
I had a hard on, and i whispered "my dick is so hard" to which Amber responded. "Show it to us". I was nervous, but i didnt hesitate. I stood up and pulled the front of my shorts down until it sprang up right in front of them.
Brandy was the first to reach out to touch it, but Amber wasnt going to be left out and she ended up touching it too. I just stood there letting them play with it until we heard their mom coming, and Amber jumped up to turn off the tv, and i sat down and put a book in my lap.
Their mom opens the door and tells us that shes going to the store, and their elderly grandmother was going to keep an eye on them, then she left.
We sat there for a few minutes, and listened for the car to pull out then Brandy asked if we wanted to play truth or dare. Amber agreed, and we got right into it. First Brandy dared me to pull my dick out again, and then Amber said truth, so i asked her something. Brandy said dare, and Amber dared her to kiss my dick. She did, then i asked Amber, Truth or dare? She said dare this time so i dared her to take off her clothes. She then dared her sister to take off her clothes. It was all dares from then on, and they each dared me to kiss their pussies, and i dared them each to put my dick in their mouths. Amber dared me to lick Brandy's butthole, Brandy dared me to put a finger in Amber's pussy. I dared Brandy to lick her sisters pussy, and then Brandy dared amber to lick her's.
I layed down on one of their beds, and Amber told me to finger her sister's ass, so i started to put my finger in her butt but it wouldnt go. Amber came closer to look, and crawled on top of me and i could feel her body touching my dick. Brandy said it wasnt working and told Amber to spit on my finger. She did, and i tried again and it went in. I dared Amber to finger herself, and she sat on my stomach while inserting a finger into her own pussy.
Brandy took my finger out of her ass and dared me to put my dick inside her sister, and without a second thought, Amber slid back and raised herself over my dick and started lowering herself onto it. I felt a little pressure and it gave way to a rush of pleasure. I was fully inside of Ambers virgin pussy, and she bounced up and down a few times before we saw the blood and all of us freaked out.
It was about a week before we hung out again, but when we did they told me that a girl at school told them that the blood was normal for their first time. We played again, and Amber dared me to put it in Brandy, so she bent over and i popped her cherry too. I shot my load on both of their faces, like they had seen on the porn. After that, we played every time we were around each other. They got to the point where they'd dare each other to take it in the ass, pussy, and mouths, and id dare them to lick each other or finger each other while i fucked them.
Sometimes, they'd have a friend over that theyd get to play with us. We almost got caught a few times, but we started going in the woods to play, and they'd bring blankets and stuff.
Ive seen them now that we're all grown up, and every time i do i want to dare them to let me fuck them just one more time...
