"Hey! Me and Isabelle are goin' to the mall, we'll be back later!" my sister called out.
"Bye bye!" I heard Isabelle yell up the stairs as I mentally blasted cum all over her tits.
After cleaning up, I began work on my homework but after a few minutes my mind was again on the sleeping powder. I decided to go back down to the computer and read more about it. I still had no true intention on trying to use something like that on Isabelle. Partly out of guilt, but more importantly out of the knowledge that doing so would be illegal.
But the days went by and my mind continued to dwell on it until one day I could no longer contain my curiosity and went to the post office for a money order and mailed off a purchase for a one month supply of the powder. I spent the next few weeks anxiously waiting for it to arrive but gradually became paranoid about the whole situation. Thoughts began to go through my mind of the FBI coming to the house to arrest me, after having monitored everyone who went to that site to purchase the sleeping powder. Then I began to wonder about whether the website was even a legit one in the first place. After all, how was I to know that they were selling sleeping powder and not regular kitchen flour.
Finally, on one afternoon as I made my way to the door I spotted a brown package by the door. It was finally here! I snatched it up and bounded up the stairs two at a time to my room where I mauled open the package. Under the brown wrapping was the website's name on a white box. Opening it, I found a small, clear container, partially filled with a white powder that looked just as much like cocaine as a sleeping aid. Inside the box was also a paper with directions on dosage and the powder's ingredients as well as a paper detailing various legal and medical warnings.
After reading through them all, I popped open the container and sprinkled some powder into my hand and gave it a sniff. Odorless. I dipped a fingertip into it and put it to my tongue. Tasteless. I sifted the powder back into the container and put the container back into the box and then the box into a low, back corner of my closet with the brown wrapping. Then I laid back in my bed, thinking about its possible use. I was shaken out of my daydream a short while later when my sister and Isabelle came in downstairs laughing about some poor guy that had tripped and spilled his tray that day in the cafeteria.
The days went by and the powder continued to sit in my closet. Though I still hadn't decided to use it, I was obsessed with it. I'd wake up in the morning and check to make sure it was still there, spend the day thinking about it, and then come home in the afternoons and sit it on my bed while I jacked off and continued to consider using it
Fate stepped in once again in a big way one evening over dinner when my parents told my sister and I that they were going out of town for the upcoming weekend.
"I want you and your brother to stay near the house while we're gone in case of an emergency," my mother requested with pleading eyes.
"Alright," my sister muttered finally. "Me and Isabelle are gonna go to the game Friday night and spend the night at her place but Saturday night we'll hang out here and catch some videos."
I almost choked on my fork full of macaroni and cheese. If I was ever gonna try out the powder, it was now or never. My intention was that I'd use some in Isabelle's drink sometime during the evening of watching movies and then when she went off to the guest bedroom to sleep, I'd be able to slip there for a short survey of her tits. That was as far as I planned on going with the powder.
I waited for the weekend like a child waiting for Christmas and when Saturday rolled around, my dick was almost painful to touch from all of my jerkoff sessions during the week. When my sister and Isabelle arrived at the house that evening from the video store, the powder was in my pocket.
"Hey, mind if I watch a couple with you with y'all?" I asked while casually placing a hand in front of my pocket to shield the bulge of the powder container.
"Of course," my sister smiled. I was certain beforehand that she'd let me watch the movies with them since she had never declined in the past but nonetheless, I had to quickly turn and stroll into the kitchen to hide the huge smile that had formed on my face.
"What do you two want to drink?" I called out while removing three glasses from the cabinet.
"Coke!" they responded in unison.
I dropped ice into the glasses and filled them with the soda. I reached into my pocket and removed the vial of powder and peeked around the corner to see my sister setting up the movie and Isabelle heading up the stairs, no doubt to change into one of her usual moviewatching nightshirts. I popped the cap on the powder and tilted it toward one of the glasses and shook in some powder.
"Can you fix some popcorn too?" my sister's voice chimed into my ears from the area of the kitchen doorway.
My head nearly came off my neck as I whipped it around toward her, quickly shoving the powder into the front of my pants.
"Sure," I replied, managing a smile.
She returned the smile headed off up the stairs to change too. I turned back to the glasses and was suddenly horrified.
"Shit!" I cursed quietly.
I couldn't remember which glass I had put the powder in! The glasses had been arranged in a triangle and I wasn't sure whether I had put it in the one towards the left or the one towards the right. A thought popped into my head and I decided to put powder into both of them. I had previously neglected to take my sister into account with my plan of going to feel up Isabelle while she slept. Even though Isabelle might drift into a heavy sleep, my sister could walk in while I'm in there and I'd be in a hell of trouble.
I sat the two glasses on the tables at each end of the couch and the bowl of popcorn in the middle of the couch. My sister and Isabelle came down the stairs and took up their usual spots on the couch while I casually shifted my chair back for a "better view of the TV".
An hour into our first movie I was beginning to wonder if the powder would work at all since both my sister and Isabelle seemed as alert and lively as usual. The movie ended with both of them seeming to be wide awake. My sister got up, appearing a bit unsteady on her feet.
"You know, I'm getting kinda sleepy. I think this is gonna be the last one for me for the night."
"Yeah me too," Isabelle said, stretching.
The joy I felt at those statements was surpassed when ten minutes later I spotted Isabelle's head back against the couch and her eyes closed. I looked farther down the couch and could see that my sister was slumped over the end of the couch and from the way her head was tilted I could see that her eyes were closed as well. I waited a few more minutes and then cleared my throat loudly.
"Ahem!"
Neither of them moved a muscle. I cleared it again, exaggeratingly loud but still neither showed any signs of being anywhere close to awake. That's when the realization hit me. If both of them were already out like a light, how would I ever be able to do anything to Isabelle? Surely I couldn't molest her while my sister sat just a couple feet away.
In stark contrast to my throat clearing efforts, I slowly eased up from my chair and made my way over to the back of the couch. I leaned over it and shook my sister's shoulder. Nothing. I shook harder and the only reaction I got was the motion of her head rocking gently with my efforts to wake her. I reached over and shook Isabelle's shoulder just as hard and got just as much of a response.
A grin, probably not unlike that of a comic book villain, began to creep across my lips. I stepped around to the front of the couch and grabbed my sister by both shoulders and shook her like a martini. Nothing. I gently returned her to her slumping position over the side of the couch. I sidestepped until I was directly in front of Isabelle and did the same. Her head bounced back and forth into the couch with my violent efforts to awaken her. They were both dead to the world.
