I had spent the last 4 years working on this drug and finally felt like I had tamed it; at least it was working on the animal subjects well enough to finally pick a human test subject. After 4 years of college, I had gotten a job at a pharmaceutical company to further my own projects more so than theirs, plus it gave me a lab for free, test animals and all the ingredients I needed. I'm just your average looking Joe, nothing spectacular here, but I wanted to find a way to make a woman absolutely melt in my presence, hence my new drug, Kaleidoscope. It was tough deciding on someone to try it on, but I finally found her, a young runaway, I had picked her up near the bus station and she was totally trusting as I invited her to spend the night at my house. I could tell that she had nothing, I felt sorry for her, but after tonight if all went well, she would leave tomorrow all cleaned up and with a full belly and even a few bucks to spare. She was about 5'7", dirty blonde hair, smallish tits, very nice round ass and although she wore a dirty pair of jeans, she had nice slender legs. Her face was reasonable clean and she had the prettiest blue/gray eyes and a killer smile, although it took some doing to finally get her to smile. Some roughnecks had been hitting on her and I managed to come along at just the right time, and she felt very safe with me, "So, what's your name?" I asked as we made our way back to my place, "Sandra," she answered and she went on to tell me that her mother was dead and her father started hitting on her so she had split, looking for a better life. I watched her as we drove, nervously wringing her hands as she fidgeted in the car seat and somewhat apprehensive as I pulled into the driveway and shut off the car, "Well, here we are, it's not much, but it sure beats a night out on the streets," I smiled as we got out and headed for the front door. She hesitated slightly as I held the door open for her, but then she walked through and sat her backpack on the chair in the living room, "Let me show you around Sandra, like I said, it's not much," and I showed her the house as we finished up in the kitchen, "You look hungry, let me make you a sandwich while you shower and clean up. There are fresh towels under the sink and here is a robe for you to wear. Leave your clothes and I'll wash them, that way you'll be all cleaned up tomorrow," and I smiled and saw her trust surface once again as she shut the bathroom door and I didn't even hear her lock it.
I set about making her a couple of ham and cheese sandwiches and put some potato chips on the plate and then made her a Coke, adding my new drug to it before setting it on the table by her plate. I heard the water shut off and a few minutes later, she appeared in the white terry cloth robe I had given her, "That felt great!" she said as I looked to see how beautiful her hair had become, now that it had been shampooed, it really set off her eyes, although once it dried, it really would. "Sit, here Sandra eat up. I'll just put your clothes in to wash," and I left her there as I went to the bathroom and gathered up her clothes from the bathroom floor and carried them out to the laundry room and started the washer. When I got back to the kitchen, she had devoured one sandwich and was half way through the other one, her Coke glass was empty, "Here let me get you some more," I said as I looked down to see the robe had opened slightly and her small, perky tits were visible from my vantage point behind her. I didn't want her to notice a difference in the Coke, so I added some more of the drug to it as I chatted with her, my back to her. I sat the Coke down and she immediately took a drink as she finished her second sandwich, "Want anything else?" I asked as I picked up her plate, "No, thank you, I'm fine," and I sat across from her and drank a Coke myself as I watched her finishing hers. We chatted all the while and she told me she had an aunt near the city that she could stay with and she was sure she could find a job, even though she was only 18 and hadn't finished high school. I watched as she loosened the robe slightly and could catch a glimpse of her right nipple as she talked, 'The drug must be taking effect,' I thought as the robe seemed to get even looser and now both of her tits were exposed and she didn't seem to care. 'So far, so good,' I thought, time to try it out, and I went around the table and stood next to her as I went to pick up her empty glass and her hand brushed my crotch as she felt my cock and began to rub it through my pants, "I could sure use some of this," she said as I watched her open the robe all the way and stroke her pussy as she stroked my cock. 'Phase one was a success,' I thought as her tongue ran over her lips constantly and small moans escaped from her mouth as her hand made me hard as a rock.
She turned sideways on the chair and worked to free my now throbbing cock as I reached down and caressed her pert tits. Her nipples were so hard, they felt like pebbles and she leaned forward and took my erect cock between her lips as her hand still worked her clit feverishly, sucking me deep into her mouth. I put my hands on either side of her head and twirled her beautiful blonde hair in them as I pumped myself in and out of her luscious mouth and she had one hand on her clit as the other one took over for mine on her hard nipples and she moaned loudly as she came the first time and to my amazement, she squirted from her pussy as I watched it coat the chair. I had never seen a squirter before, I had heard about them, but Sandra was my first one in real time. She shifted her head in my grip and I could feel her throat closing around my cock as I pumped her mouth full of cock and in no time, I was blasting jets of hot cum into her mouth and she gurgled as she swallowed it, making sure that she got every drop. She pulled her mouth off of me, but continued to jack my cock as she licked her lips and stared up at me, those eyes were quite enticing and my cock began to grow once more, "Please fuck me, I need to be fucked so bad," she pleaded and then got up, dropped the robe and lay across the kitchen table on her stomach as she spread her legs, inviting me inside. As soon as I got the head inside, she lurched back against me, her wet pussy swallowing me up as she moaned and I filled her tight pussy. "I don't know what's wrong with me, I can't seem to get enough," she cried as she bucked her hips back against me and I smiled to myself, I knew, my drug was a partial success anyway, we would have to wait until morning to see if it was a total success. Having just cum in her mouth, my cock was in no hurry to explode again and I just enjoyed her tight little snatch and thrust in and out, her screams getting louder as she came and came again. "I want more!!!" she screamed and I asked what else she wanted, "I've never done it and don't know why I want it, but fuck my ass!!!" she screamed out and I withdrew and positioned my cock at her back door as she nuzzled against it, almost begging to have her cheery ass taken and I was just the guy to help her out.
She hadn't lied, she was a cherry, her ass was about to strangle my cock as I finally managed to get the head inside and she quickly pushed back to capture all of me, her grunts signaling her virginity as my cock felt like it was in a vise. "Oh God it hurts!!! But I love it!!" she screamed as she now did most of the fucking, my cock buried time after time between the sweet cheeks of her round ass. I worried that I would hurt her, instead she was loving it as her ass relaxed and it felt like a tighter version of her sweet pussy as she fucked back against me. I couldn't take any more and my cock exploded, filling her tight ass with cum as she screeched out yet another orgasm and then I collapsed on top of her, my cock still buried in her sweet ass. As we began to catch our breaths, I noticed a slight change in her and figured the drug was wearing down, so I pulled out and told her to go shower again and I would fix her a cold drink. As the water quit, I had her drink ready and had redressed and now sat nervously waiting to see if I had succeeded. I noticed she had a peculiar walk as she returned to the kitchen, "You feeling ok?" I asked as she sat down in the chair, "Yes, just a little sore for some reason," and she drank her Coke and I showed her to her room and said goodnight, it had been a success, no recollections at all. My amorous activities made me sleep like a baby and I jumped when the alarm went off and nearly broke the clock shutting it off. I lightly tapped on Sandra's door and turned the knob, her sweet body presented itself to me once more as I watched her sleeping, her covers had been kicked off and she lay there nude, my eyes transfixed on her childlike innocence. My cock began to rise, but I knew that she couldn't be touched without the drug, so I quietly closed the door and knocked harder this time, hearing her gathering the covers around her and say. "Come in," and I told her it was time to get up and set off to make us some toast and orange juice. I felt her enter the kitchen and turned to see her clad in the robe, I had forgotten about her clothes I had washed, and I set about getting them from the dryer and handing them to her. As she took them from my hands, her robe opened slightly and I got to see those pert young tits of hers once more as she blushed and turned away.
