I am honestly unable to remember one single damn thing that happen at school that day.

I went through all of my classes and interacted with my friends in a thick mental and emotional fog. Fortunately, nothing important happened, I was a pretty good student, so the teachers cut my obvious and uncharacteristic absent mindedness some slack, and my friends had other things in their own lives to worry about other than what was bugging me.

My mind had been locked in a never ending loop, going over and over my encounter with my mother that morning. Her round and firm ass cheeks occupied my brain and my cock had been half hard practically the entire time. I actually popped into a gratefully empty bathroom just before my lunch period and silently jacked off in the limited privacy of a clean stall, fantasizing about my mother's body. It was without a doubt, one of the biggest self-induced orgasms I had ever experienced. Still, after no more than an hour, I was once again hardening and I knew that I would have to jack-off once more upon reaching the comfort of my room, or I wouldn't be able to sleep tonight.

'God damn it! I really am sick!' I thought angrily to myself. 'First I get the hots for my little sister. Then I go and develop a full blown Oedipus complex! It's just so ... sick and wrong!'

But as I had already come to realize, the simple fact that it was wrong, prohibited, naughty, made it all the sweeter.

Believe it or not, but I had never actually thought of my own mother as a sexual object before. Honest! Sure, I had admired her beauty and her curvy body before. I'd have to be dead not to, even if a few of my braver friend's comments hadn't brought her MILF status to my attention. But she had always simply been "mom" to me, and I had many other more convenient and suitably appropriate outlets for my lustful fantasies. Now though, I couldn't keep from remembering how my cock had felt nestled between the globes of her luscious backside. Remembering and wishing that I could somehow feel it again. Imagining what her naked body would look like and how it would feel under my roaming hands.

At the end of the day, while on my way home, the fog finally began to lift and I found myself dreading what I would find there. I wondered and worried about my future.

How pissed was my mother and what would she do?

What did Andie think about me perving on our mother's buxom breasts?

What would I do if Dad ever found out?

No comforting answers came to mind.


I'd managed to avoid my mother ever since she came home from work and she had obviously been doing the same with me. The only time we were actually forced together was during dinner, but she didn't say a word. I could tell by the way she stomped around and banged things as she prepared dinner and set the table that she was still pissed, so I just kept my head down and my mouth full of food.

I admit that it was not particularly atypical behavior for me.

Andie felt the tension and was silent as well. I didn't look at her, afraid at what I might see in her eyes – anger, disgust, hurt ... Dad on the other hand, was gratefully oblivious, caught up in some important work project.

As soon as possible, I excused myself from the table and headed straight to my room, mumbling that I had a book report to finish up. A few hours later my schoolwork was all done (to keep busy, I'd actually read ahead in a couple of classes) and I was relaxing on my bed, engrossed in a brand new sci-fi novel, when I heard a ding coming from my computer. I reluctantly got up and sat at my desk, knowing that Andie was trying to chat with me.

I dreaded how she was going to react.

Andie – wr u rely chekin out mom dis mrnin?

'Wow, she just dove right in there, didn't she?'

I hesitated, momentarily considered lying to her and playing the whole thing down, making up some sort of excuse. But, I ultimately decided not to. We already shared the biggest secret in our lives, so it didn't seem rational to start hiding things from her now. I trusted and cared for her, so I should prove it by being completely honest and hope for the best.

Matt – Yes, I was. I couldn't help it ... she's a damn hot woman.

Andie – wow! u rely r a perv! lol ;)

Well, she didn't seem to be taking it badly. She couldn't really look down at me for thinking my own mother was hot, when she was busy flirting with and flashing her own brother.

Now, let's see how she reacts to the whole story.

Matt – You don't know the half of it...

And then I went on to recount what had happened before she entered the kitchen in excruciating detail, adding what I was thinking and feeling at the time. I even explained how distracted and horny I had been at school all day, having to jack off in a bathroom. Running through the events once again, I couldn't help but pull down my pants and start slowly masturbating to the delicious memories.

After I finished, there was a long pause. The connected icon was still there, so I knew that she hadn't closed the program or her computer.

'Dammit! Had I taken it too far ... been too graphic?' I couldn't help but wonder, desperate worry eating at me as the silence stretched on.

Just as I was about to send another message, I received an answer.

Andie – OMG! i cnt bleev i cam so hrd!

I stared at the words on my screen for a while, not really understanding them. After I eventually pieced it together, a few more moments passed with me just sitting at my desk in stunned disbelief. Had Andie actually masturbated, jilled off and eventually orgasmed as I told her about dry-humping our mother's ass in the kitchen, not ten feet from our father?

My rock hard cock rhythmically pulsed in my hand and started to drool precum as I imagined it.

Andie – i cnt bleev dat i jst tld u dat!

Matt – I guess that means that I'm not the only perv in the family, am I?

No response for a few moments.

Matt – Are you still there?

Andie – u dnt tnk dat im sic do u?

Matt – No Andie, I don't think that you're sick. At least no more sick than I am. There's nothing wrong with fantasizing and you shouldn't feel guilty about anything that turns you on.

I love you, always. You know that.

Andie – i knw. i luv u 2. thnks Matt.

Matt – I do wish that I could have seen it for myself. I often fantasize and masturbate about you touching yourself.

Andie – i dnt thnk dat im redy 4 dat. mayb sum dy.

There was another long pause.

Andie – wen I tuch mself i thnk abt u 2.

Matt – Tell me about it. Tell me how you touch yourself. Tell me what you fantasize about.

I was typing one handed by now, the other occupied stroking my hard and dribbling cock.

It took a bit of coaxing, but eventually I had my sister describing in great detail how she masturbates and one of her favorite sexual fantasies, featuring yours truly. It was a girlie, almost fairy tale like scenario, but a very hot one.

We were both guests at a fancy masquerade party who met, got along quickly and flirted shamelessly, not knowing that we were in fact brother and sister. Quite soon we moved outside, away from the music and crowds and began making out passionately and feverishly groping each other over our formal clothing. As we finally gave in to our primal impulses and disrobed, our masks fell and we discovered our true identities. But, by that time, we were both so hot and horny that we didn't care about the taboo of incest. In fact, it only made us even more excited. So, on top of the cool grass and under the full moon and stars we made sweet and hungry love.
