When Tommy Murdoch was 8 years old, his parents gave him a chemistry set as a birthday present. Little did they know that five years later, at the age of 13, that chemistry set would lead to Tommy inadvertently losing his virginity… to his sister.
Now, please don’t judge him harshly. It really wasn’t his fault. He certainly never planned for it to happen. In fact, he was quite shocked when it did happen, but… that’s getting ahead of the story.
Tommy was a bright, inquisitive kid, always wanting to know how things worked or why things happened the way they did. He breezed through all the experiments that came with the chemistry set in a matter of days. Then, using his allowance, and later paper route earnings and birthday money, he bought chemicals online and spent most of his free time in his own little world, learning everything he could about chemicals and chemical reactions.
Tommy was barely 11 when he learned that his penis was good for something other than peeing. He woke up one night to find it swollen to several times its normal size. He noticed for the first time that hair was just starting to grow around it.
At first, he thought he had injured himself somehow. When he’d twisted his ankle the summer before, it had swollen to more than twice its normal size, so he assumed the swelling of his dick was for the same reason. Except… it didn’t hurt.
He poked it a few times with his finger but that didn’t hurt. He wrapped his hand around it and squeezed. Nope, no pain. Felt pretty good actually. Then he started stroking it, and it felt better and better. Fascinated, he laid back down and closed his eyes as he continued to pump his fist up and down. His breathing got heavier as it felt better and better with each stroke. He got to the point where he felt like his body was going to explode because of how good it felt.
Of course, his body didn’t explode, but his cock did, spraying himself with a huge load of cum as he pleasured himself to his first orgasm. He squirted all over his upper body, almost as far as his neck. Panting now with the effort he had expended, he could only lay there in amazement at what he had just done to himself, all by himself.
The days to come would find Tommy, with his inquisitive mind, doing a great deal of further experimenting with a certain part of his recently pubescent body.
It wasn’t until his third year in middle school that he began to notice more of the world around him as he gradually became more aware of his classmates, especially the girls. He’d never had any use for girls at all until recently, when one girl in particular began to hold his interest. He’d known Mikayla since they were in kindergarten and always thought of her as a scrawny little girl who seemed to have a lot of skinned knees and elbows. She was a regular little tomboy… or at least, she used to be.
But just as puberty had been making changes to his own body, Mikayla was also being transformed from a little girl to a woman, by way of adolescence. Noticeable bumps under her sweater did not escape his attention. Nor did the alluring curve of her butt in a tight pair of jeans, whereas before her bottom had always been skinny and shapeless.
By the time they started the eighth grade, Mikayla’s nascent development had Tommy hopelessly in love with her. However, as smart as he was, he didn’t have a clue about how to talk to the girl and he spent countless hours just daydreaming about her. More than a few of those hours found his erect penis in his hand.
In December of their eighth grade year, he was elated when he drew Mikayla’s name for the Christmas gift exchange, and it suddenly hit him like a bolt of lightning. He would give her perfume. Not just any perfume—certainly not a store bought perfume—but a unique fragrance just for her, which he would create with his own chemistry set.
He—and his family—had long since stopped using store-bought soap, shampoo and toothpaste as well as various cleaning products. He could make them better and cheaper than the commercial products foisted on consumers and he had experimented with different scents for the compounds he created. He was sure he could come up with a fragrance that would magically convey his love to Mikayla.
Night after night for more than a week he experimented with a variety of essences. A week before the school Christmas party, he added the barest hint of rabbit musk to his previous compound, which seemed to blend well with the scent of citrus and rose hips he had based the formula on. He was satisfied that he had created a perfume that would enchant the girl of his dreams.
He was going to ask his mom to sample it, then remembered that his parents were out for the evening. That only left his sister Courtney. Well, she was a girl and she was 15 so she should be pretty knowledgeable about fragrances. Wearing only his flannel pajama bottoms, Tommy took the bottle and walked down the hall to her room.
Courtney was sitting on her bed, wearing a pastel blue shorty nightgown and panty set, and looked at him curiously as he knocked on her open door before entering.
“Hey Courtney. I’ve made up a special perfume for a girl in my class. Would you sample it and tell me what you think?”
Being a typical older sister, she couldn’t resist teasing him. “Ooh, Tommy-has-a-girlfriend,” she trilled in a sing song voice.
His cheeks reddened a little but he tried to ignore her teasing as he answered, “Oh, cut it out. I just drew Mikayla’s name for Christmas and made up a unique perfume for her. I just want to know what you think about the fragrance. I would’ve asked mom but she’s not here.”
Courtney took pity on her baby brother and motioned for him to sit on the bed next to her. She reached for the bottle and dabbed a drop on her wrist, then lifted her arm to her nose and sniffed. Tommy wasn’t sure what to think when his sister suddenly lifted her wrist a second time and inhaled sharply.
He really didn’t know what to think when her eyes glazed over. Then she put her arms around him and kissed him—hard—right on the mouth. Her gloss covered lips were soft and open as she pressed them against him, trying to force her tongue through his closed lips.
Tommy closed his eyes, trying to figure out what the hell his sister was doing. He felt embarrassed when a certain part of his body seemed to be slowly reacting to the feeling of a soft warm female body touching his bare torso, especially since that body belonged to his older sister.
Courtney broke the kiss, pushed him down on his back and climbed on top of him, her knees straddling his hips. With one swift motion, she peeled her nightgown off. She leaned forward and began kissing him again, her firm teenage tits pressing against the confused middle school boy on top of her frilly bedspread.
Tommy was now keenly aware that one of his private body parts was now fully engorged as it responded to the barely covered adolescent girl parts grinding against the most intimate part of his body.
Even through his pajama bottom, the eighth grader could feel the heat radiating from between his sister’s legs. Courtney sat up, squirming her hips as she ground her mons pubis against his now fully erect cock, her 15-year-old pussy making her panties wetter by the second.
Tommy opened his eyes, and it was his turn to inhale sharply at what he saw. The last time he’d seen his sister bare chested, he’d been 7 and she’d been 9. At that time, six years ago, her chest had looked a lot like his own.
That… was no longer the case. Courtney’s ripe young body looked very little like it had when she was a 9-year-old. Her firm B-cup breasts jutted almost straight out from her chest, almost filling Tommy’s vision, or so it seemed to him. But it may very well have been that he couldn’t see much else because he didn’t want to see much else. Either way his eyes widened as they locked on his sister’s ripe naked bosom.
Breathing rapidly, he hesitantly reached his hand up until his fingers closed around one of the jiggling globes of mammary flesh. Courtney moaned and Tommy felt her nipple harden at the touch of his fingers. She reached up and squeezed her other boob herself. Her ample breasts were bouncing now as she wiggled her shapely teenage bottom, putting more and more pressure on her confused brother’s swollen dick.
Abruptly, the girl climbed off of Tommy and quickly stripped his pajama bottoms off, then nearly ripped her panties in an effort to peel the crotch away from the sodden core of her sex. Elbowing him to the side, she laid back with her head on her pillow, spread her legs wide apart, and pulled Tommy up on top of her. Reaching between them, she took a firm grip on his rigid cock and guided it until it began to slide rather easily inside her very wet, very hot, very needy pussy. Courtney whimpered as the 13-year-old boy’s manhood sank deep into her core.
Although Tommy’s only experience with sex before now was playing his own fiddle, he didn’t have to be told what to do once his dick filled his sister’s demanding cunt. He plunged his cock as deep as he could, then withdrew and did it again… and again… and again. Courtney was gasping and murmuring encouragement. “Fuck me Tommy. I want your cock. It feels so good in my pussy.”
Tommy was in heaven. As one can imagine, hearing a girl saying such naughty words was exciting to the young lad. Not to mention that the female orifice that had swallowed up his dick felt incredible. And here he’d thought his own hand felt as good as it could get. He pumped in and out of his sister’s young pussy faster and faster, like he’d been doing it all his life. The wet squelching noise of each stroke was nearly as arousing as the feel of her hot adolescent folds. Courtney was squirming her butt and thrusting her hips up off the mattress to meet every stroke.
Alas, 13-year-old boys do not have a lot of staying power. Tommy suddenly felt his cock unload, spewing his cum deep in his sister’s sex tunnel, but he didn’t even slow down. He pumped faster and faster, encouraged by Courtney’s hands gripping his butt and pulling him hard against herself until she arched her back, then cried out before going limp. He collapsed on top of her, both of them breathing hard.
Eventually their breathing slowed, and Tommy started to ask what she thought about the perfume, but then decided that it didn’t matter whether she liked it or not. It wasn’t for her anyway, it was for Mikayla.
Finally, Courtney unceremoniously pushed Tommy off of her and headed for her bathroom, announcing that she needed a shower. Tommy decided he needed one too and left for his own room.
The next morning as the two of them sat alone in the kitchen having breakfast, Tommy said, “Wow, that was really something last night.”
Courtney gave him a blank look, and said, “What about last night? What are you talking about?”
Puzzled, Tommy tried to figure out what to say next, but finally just shook his head. “Never mind.” He spent the whole day in a bit of a funk. He and his sister had fucked like wild animals, but Courtney didn’t seem to remember anything they’d done. As smart as Tommy was, he just couldn’t figure out what to make of it.
Finally the day of Tommy's class Christmas party arrived, and as much as he’d been looking forward to giving Mikayla her gift, he was mortified when he got to school and realized that he had forgotten to bring her present with him. He felt horrible, but there was nothing he could do about it. He wrote Mikayla a note explaining that he had drawn her name but forgotten to bring her gift to school. He promised that he’d come to her house after school and give it to her then.
She smiled at him and nodded that she understood and he didn’t feel quite so much like an idiot. Now that he thought about it, he decided that this would actually work out for the best. Perfume was a personal type of gift and he thought giving it to her privately would be better anyway.
As soon as he got home from school, he picked up the beautifully wrapped package and rode his bike over to Mikayla’s house. When he rang the bell, she opened the door, still wearing the festive party dress she’d had on at school, the bottom skirt of soft black velour and the top part a shiny red sateen. Tommy thought it looked really good on her, emphasizing how narrow her waist was, the flare of her hips and the delightful swell of her still-developing breasts.
“Hi Mikayla, thanks for not thinking I’m an idiot. This is for you. It’s perfume, a formula that I created myself, just for you.” Crap, why did I tell her what it was? he thought. She’s supposed to unwrap it to find that out.
Mikayla didn’t seem to mind as she eagerly ripped the paper off and looked admiringly at the bottle. “This bottle is beautiful, but there’s no label. Does it have a name?”
“Uh, well. I hadn’t thought about that. I suppose we could call it Mikayla, since it’s one of a kind, just like you,” he said. Jeez, he chastised himself. Could you say anything lamer?
The smile she gave him nearly took his breath away. Maybe that wasn’t such a lame thing to say, he thought. He managed to stammer, “Try it. I can’t wait to see if you like it.”
She dabbed a bit on both her wrists and touched a drop to her neck. Breathing it in, she said, “Oh, Tommy, this is heavenly. I feel like a glamorous movie star.”
Tommy smiled, but the smile turned into more of a grimace on his face when he saw her eyes get the same smoldering glassy look that Courtney had gotten the night she had tried it. He was holding his breath as Mikayla stepped up and put her arms around him and gave him a hug. She kissed him, mouth open and tongue probing, even as she took his arms and guided his hands until they rested on her well rounded butt cheeks.
That was when the light bulb in his head finally flashed on. Holy crap! I’m such an idiot. It was the perfume. He had somehow created a fragrance that made girls violently—aggressively—horny. And based on his experience with his sister, he was willing to bet that Mikayla was not going to remember anything they did here.
Before he could even wonder what they were going to do here, Mikayla pressed her firm young mound against his crotch and he stopped thinking altogether as he felt himself getting hard. As he became fully aroused, she continued to grind her 13-year-old groin even harder against him. Then she moved just slightly back, giving her enough room to slide her hand down inside the front of his pants. They both gasped as her slender fingers curled around his cock.
She breathed, more than spoke, “Oh Tommy.” Using her other hand, she undid his fly and pulled the zipper down. She pushed his jeans and shorts down around his knees, then bent over and touched her lips to his dick as she went to her knees on the floor in front of him.
He moaned and closed his eyes, enjoying the incredible feeling of having his cock in a girl’s mouth for the first time. Mikayla seemed unable to get enough while she ran her tongue and lips up and down his erection. When she stopped, he opened his eyes and saw Mikayla’s black lace bikini panties on the floor, and her party dress pulled up around her slender waist. He had no idea how she had gotten her panties off while giving his dick a workout with her mouth.
Putting her arms around his neck again, she jumped up and wrapped her legs around his waist. Without even thinking he cupped his hands under the firm flesh of her delightful derriere to help support her weight.
She whispered in his ear, “I am so… fucking… horny. My pussy is so wet and ready. Got to have your cock.” Tommy almost blew his wad, hearing such nasty words coming out of the sweet young girl’s mouth. Then again, just moments ago said sweet young girl’s mouth had been busily sucking his dick like it was manna from heaven.
Mikayla pressed harder against him, and he again felt the incredible wet heat of a sexually aroused girl. She was squirming her butt and hips, each movement designed to get her pussy in a position where she could impale herself on his dick. She practically purred when she found what she so badly wanted. She was so wet, Tommy’s rock hard cock slid easily inside his eighth grade classmate’s incredibly tight pussy as she impaled herself on his tumescence.
Mikayla was nearly whimpering as she jockeyed up and down, fucking herself on Tommy’s cock while he simply stood there and enjoyed the way it felt to have her hot pussy surrounding his adolescent dick. Even in his wildest fantasies about the girl, it had never been anywhere near this exciting.
“Fuck me Tommy. Fuck me hard. Oh gawd, I love your dick. Fuck my pussy with your cock.” He could barely make out the words, her guttural rasp alternating with squeals of pleasure. Then, he came.
Shuddering, he emptied his balls, but Mikayla seemed not to notice that he had sprayed her insides with cum. She rode the boy’s cock frantically, until several minutes later when she finally climaxed with a scream, her orgasm so powerful it caused her cunt to clench around his cock so hard he almost cried out. The two youngsters just stood there panting, their bodies still connected through their sex until their breathing finally slowed to near normal.
At some point, there was a soft plopping sound as Tommy’s slowly softening dick slipped out of Mikayla’s well fucked 13-year-old treasure. Again using her arms around his neck to support her weight, she unwound her legs from his waist and put her feet on the floor. The hem of her dress dropped to just above her knees, and she was standing there fully dressed… except for her panties, which were still in a heap on the floor.
With the exception of the two rosy red circles on her cheeks, she looked exactly as she had when the door opened. She kissed him again, more gently this time, and said, “Wow, that was wonderful, Tommy.”
Tommy’s brain shifted back to what he had realized moments before. Now anxious to leave, he hugged Mikayla again, so he could reach behind her to pick up the 8-ounce bottle of the magical fragrance. Without bothering to explain, he turned and fled. She wasn’t going to remember him even being there anyway, if his experience with his sister was any indication. I’ll just buy her a bottle of perfume at the drug store and give it to her tomorrow, he thought.
Riding his bike away from Mikayla’s house, Tommy cringed as he thought about what might have happened if he’d given her the special perfume in school earlier that afternoon. All the girls would have wanted to take a sniff… even he knew that much about girls. He couldn’t even imagine what would have happened with 14 hormonal—and aggressively horny—eighth grade girls going sex crazy in the classroom, especially since there were only 10 boys in the class.
Abruptly, he had to stop and get off his bike, feeling like he was about to throw up. He had suddenly remembered how close he’d come to asking his mother to try out the fragrance. His mind couldn’t even go there. It had been bizarre enough having sex with his sister. He’d never really thought about losing his virginity the way girls sometimes do, but if he had thought about it, his own sister would not have been involved.
“I’m such an idiot,” he said out loud. “How stupid could I be not to have figured out what set Courtney off?” Thinking about his well-developed sister, naked and spread eagle on her froufrou childhood bed with her hairy little pussy exposed made his dick begin to stir.
With high school and college ahead of him, he had big plans for the little bottle he clutched in his hand. He was so glad he’d always been meticulous about writing down formulas as he worked because he had a feeling he’d eventually need another batch of this particular creation. Maybe he could even tweak it to… I’ll have to think about that! he mused.
Who would have ever thought that giving an eight-year-old boy a chemistry set would unlock the secret to an incredible sex life. And Tommy was still in middle school…
THE END
