So I got home from all the holiday get together's and collapsed into my recliner chair. My body was so fatigued and so was my mental status. My mind was racing with the crazy sex I just had with my two older sisters. Was it all a dream? Did I just have incest with my sisters? I just couldn't wrap my brain around that fact. This was big, this was huge, this changed everything. My life had now taken a very dark turn. I started to question what kind of person I was. I certainly couldn't put the blame on my parents. They did all they could to shield us from the evil ways of the wicked world. So how did I become such a sex crazed pervert. I mean even before this incestuous boundary crossing, I was always thinking of dirty rotten filthy sex but I had very little success trying to get a willing partner to go there. Turns out that both of my sisters are just as perverted as I am, and in my oldest sister Becky's case, maybe even more so. That girl is one sick chick.
So I sat there thinking of all the possibilities that we could explore. I mean Becky sounded like she was ready to do just about anything and everything. My cock got a jolt at the thought of unlimited sex. As I let my mind drift I fell asleep in the chair and was woken up by the phone. I groggily answered the call,
"Hello." It was Becky teasing me saying,
"Well hello to you too mister sleepy head. Did I just wake you up?"
"Sorry, uhh yeah, I was just catching a little power nap. What's up?
"Well to tell you the truth, I can't stop thinking of what happened this weekend. My mind is going crazy. And since I can only talk about it with you and Lisa, well, I just had to talk to someone. I mean how do you feel about all this?"
"Well, it all seemed to happen so fast. One minute we were watching TV and the next we were banging each other. I guess I'm still in shock but not in a bad way I guess, just more in disbelief is all. I just want to make sure I can still separate myself from all the other sickos in the world. I mean most people would consider what we did pretty disgusting."
"I hear what you're saying little brother and I know full well that I was the one that bullied you two into this. I don't know what came over me. You should know that you're not the only one with a perverted mind. I think of dirty sex all the time and I've had some wild sex in the past but none of it came close to what we did."
"Really? I had know idea you had sexual desires like that. I thought I was the only sick bastard in this family."
"Guess again Tone, I'm as sick and twisted as they come. But as well as I thought I knew Lisa, she surprised me with a few hidden sexual perversions herself."
"Yes I totally agree. Girl can scream like nobody's business. But what I never knew was how much of a squirter you two were. Man that was hot."
"Oh yeah, ever since puberty. Lisa came to me when she had her first squirting orgasm and thought she was defective. My whole life has been devoted to cleaning up after myself. I've been washing sheets ever since I can remember. To tell you the truth it kind of gets annoying but it does make for a dramatic visual doesn't it?"
"I'll say it does, shit. That shit was over the top. I was not expecting that at all." Becky laughed,
"So I guess it's safe to say that you're not so freaked out by all this and haven't ruled out the possibility of more fun and games?"
"No... I could be talked into trying this again."
"Talked into he say's. Dude you know you want to fuck me again. Don't even act like I have to talk you into anything you perverted piece of shit." I laughed,
"Okay okay, you got me on that one. I'm definitely up for this again."
"I thought so. So......... when?" Becky always was direct about certain things. I answered,
"Damn girl, you're already up for more aren't you, you horny little bitch."
"Well, who knew my little brother was packing a god damn monster in his pants. You know I've always wondered how big you were. I've seen you in a bathing suit but you don't really wear form fitting Speedos. That was my first look at your cock. Very impressive bro."
"Thanks. I've never had any complaints from the ladies."
"So...... when? When can I feel my little brother's thick hard cock up my ass again?"
"I don't know. Not tonight I know that. You guys wiped me out man. I'm fucken beat."
