Note from author: This was partially based on and inspired by something that happened in irena_adler's Watson 'Verse. There are no serious spoilers in this fic, other than a small one for the section "Sign on the Door". This is the first fic I've written in ages and my first fic for the Numb3rs fandom, comments are very much appreciated!
I heard the front door shut downstairs. Dad must have left to go and get some groceries because he’d been planning to make lasagne but we’d ran out of pasta sheets. I didn’t let my mind wander for too long though, and I pulled my thoughts back towards using the Maclaurin series in a proof for the probability generating function of a variable with a poisson distribution.
The equations danced in my mind and flowed smoothly down my arm and out onto the squared paper in front of me. My fountain pen left neat marks as I worked my way through the proof. I’d gotten almost to a point where I could start thinking about what to substitute for the reverse Maclaurin expansion…
And then I heard the doorbell ring.
Did dad forget his keys?
"Hey you", Don’s voice said. He sounded unusually excited, but then I heard nothing more. Thinking nothing of it, I grabbed my headphones and cassette player, climbing back into my bubble of abstract thought. I wanted to understand this proof. Maybe writing it out on my own without help would help me to understand the connection between a binomial and a poisson probability distribution. Probability was a fascinating thing: it allowed you to predict the future. Not with certainty, but nonetheless.
Above the music, I heard footsteps coming up the stairs. But not just Don’s: there were two sets of footsteps. Oh. Don must have brought his girlfriend over. Don had snagged himself by far the hottest girl in our grade at school. It was bizarre being a high school senior at 13, but just like everyone else I still had a crush on the cheerleading captain. She had the most gorgeous curves and long strawberry blonde hair that framed her face beautifully. She had the dreamiest eyes too.
And I guess home alone time is ideal for… Well… A wave of jealousy flared up inside me. Don could have any girl he liked, as the baseball team captain. He was practically good enough to play league baseball. He was the coolest kid in the school, with the a brother who was by far the weirdest.
He’s not even paying any attention to the fact that I’m right here next door in my own room. He probably thinks I’m so engrossed in my mathematical work that I won’t even notice.
I hear his bedroom door close, and without thinking pause the cassette. Maybe out of curiosity towards what they were going to do, maybe because I wish I could just be Don, just for a little while. I’d completely lost my train of thought about the probability generating function anyway, there was no point returning to that work now. Instead I went to go and sit on my own bed, right next to the wall that separated Don’s room from mine.
Don giggled softly. I heard her murmur something in response, her tone of voice sweet and thick as honey. I heard them kiss, and Don moaned softly.
There was a great deal of shuffling between them, and then there were more murmurs. The sound of Don’s belt buckle landing on the carpet gave it away that they were no longer dressed.
Images of the two of them on the bed, entwined in one another intimately with their tongues dancing around each other flashed across my mind. It was an entirely absorbing image, despite the fact that I knew I’d never let Don find out that I was listening.
My cock grew and throbbed in response to my thoughts, and I noticed a very visible bulge forming under my jeans. I unded the button and opened the zip, my hand reaching down through my boxers. The touch sent shivers down my spine as my eyes fell closed and I leaned my head back, sighing.
I was suddenly brought back to reality realising that the wall was not a one-way street for sound. What if Don heard me?
But then I entwined my fingers around my stiff and swollen cock and slowly dragged my hand upwards, and my brief panic faded.
"You sure?" I heard Don say quietly, concern and love audible in his voice.
"Yes, I love you Don"
Then Don moaned louder, possessively, almost needily and she giggled softly in response. I imagined Don, naked, grinding against her stunning body. She purred in response.
My cock twitched in my hand, and I ran my index finger up and down the sensitive underside and circled it around the sensitive head.
I could pictureDon on his back, his muscular torso in full view and her straddling him, taking his cock. I heard her giggle slightly, before she let a sensuous moan escape when she sank all the way down.
From the sound of what was going on, she was riding him and that Don was thrusting from underneath in response. It must feel so good to be you right now, Don.
My mind sent images of her leaning down to kiss Don with urgency, their tongues colliding, responding to the sensations they were experiencing from each other’s bodies. Her soft long hair would fall down around his face, engulfing them in their own world, where nothing else exists. Yeah, and especially not me, the next door neighbour who is currently having a great time feeling jealous and getting off solo, huh?
Then I heard Don’s voice again. "I’m gonna… I’m gonna cum, babe"
He was panting, his words entangled and urgent. Then he grunted and the thought of him releasing his hot cum deep inside her was too much. My hand slid up and down my cock faster, aided by the precum that had formed, and soon I began to tremble. I kept going and soon white cum poured all over my hand.
I sat for a moment, catching my breath.
I went to go and grab a tissue from my desk, praying and hoping like hell that my activities had gone unnoticed.
