Stacy's Pheromones, Part 3

by Polly Ester

Stacy shut her door and stood there in shock for several minutes trying to process what had happened. Had Penny been... hypnotized or something by her pussy juice? Her girl cum seemed to have gotten her sister instantly and irresistibly horny! That couldn't be right, could it? Quickly she made her way to her computer and did some searching. It was hard to do a search about a smell that could make girls horny without coming across a lot of porn sites and Stacy's pussy started to tingle and lube up. She was still naked and she felt her chair begin to get slippery. Several times she bookmarked a site to check out later but she forced herself away and maintained as much focus as she could on her research.

She soon started reading about pheromones, chemicals that animals released into the air that could drive other animals wild and initiate the fun sexy times. She couldn't find any indication that this kind of thing had ever happened in humans, but that didn't mean that it wasn't possible, right? Maybe her pheromones were stronger than most people's. Were there others like her? She couldn't find anybody saying that they'd had an experience like hers, but that didn't mean that there wasn't. After all, people would tend to keep this type of thing secret, and it seemed like a strong enough dose of her pheromones induced a sort of amnesia afterwards so most people wouldn't even know to talk about it.

Or maybe she was just being silly. Maybe the incident with Penny was just a fluke and something else caused her sister to go nuts. That had to be it, right? There had to be a way to test this to make sure. She looked around her room. She was going to have to do some cleaning, she saw gobs of her girl cum splattered in several places from her activities just minutes before. She could use some of it to test with, though. She needed to make it inconspicuous... she noticed a quarter-filled spritzer of perfume spray on her dresser. It was the kind with the twist-off lid. She opened it up and scooped her pussy juice into it until it was full. She then shook it up and tested it and it spritzed out well. It smelled muskier than before but the perfume mostly hid the smell.

She got dressed and headed out into the living room. Her older sister Janine was just coming in from the kitchen, a perfect opportunity! Janine was 14 with short mousy brown hair. She as wearing a tight tank top and a pair of jeans. Her breasts and hips were both very nice and curvy, but not too big. Stacy noticed appreciatively the way her breasts jiggled as she bounced into the room. "Hey Stace, what's up?" she asked.

"Hey Janine. I got this really cool body spray and thought you'd like to have a whiff." said Stacy. Without waiting for an answer, she sprayed the bottle straight at her sister, giving her three blasts for good measure.

Janine breathed in the spray. "Mmmm... that's a nice smell... I think there's something a little... unusual about it though..."

The effect was remarkable. Just a minute before Janine had been bouncy and carefree as usual. Now, Stacy saw quite clearly that she was starting to become very distracted. She was running her hands up and down her sides, making a visible effort to keep her hands away from her pussy and breasts.

Janine didn't know what had come over her, but all of a sudden she was getting really horny. Being a 14 year old girl, she was actually horny a whole lot, in fact she usually felt a slight tingle in her pussy for most of the day that she had to ignore until she got the chance to masturbate. But this time her tingle ramped up to a fever pitch and she was itching to stick her hand in her pussy and go to town.

Noticing her sister's discomfort, Stacy decided to be a little evil and tease Janine a little bit. "Hey," she said, "Why don't you sit down for a bit and tell me about your day?"

"Oh, there's not much to tell, I'd just like to go and..."

"C'mon, just sit for a minute! We're sisters, we should talk once in a while!"

Janine whimpered slightly, but she couldn't think of an excuse so she sat down. She crossed her legs tightly and hugged her knees a little.

"Why don't I tell you about my day a little?" Stacy started, "We had the use of the pool for gym class today, I wore that new bikini I bought."

Janine squirmed, she seemed to be holding her breath. Stacy grinned, her own pussy spasmed slightly knowing that her sister was getting really horny thinking about her in her bikini. "It rode up my butt crack a little bit, " she continued, and then leaned closer and whispered conspiratorially, "And I think it outlined my vagina a little bit too. Good thing I go to an all girl's school!"

Janine immediately let out a long, shuddering moan. Her eyes were glassy, it seemed she didn't even notice that she made a sound. Her breathing was coming out in ragged gasps.

Stacy sat back and enjoyed watching her sister squirm, and then said "So, why don't you tell me about your day?"

"Oh, um... there's not much to tell... hey, why don't we talk later, I've got something to do right now okay?" Janine quickly got up and without waiting for an answer rushed off to her room.

Stacy got up. The experiment was an unqualified success. It seemed that her pheromones were so powerful they could drive other people into a lustful frenzy. She stopped by her room to grab her girl cum soaked pillow, and headed for Janine's room. She wasn't surprised when she opened the door to find Janine on all fours with her pants and panties around her ankles and her fingers buried in her pussy rubbing vigorously. She didn't even notice Stacy enter, but she was moaning "Oh yesss... Stacy!! Oh, I want to touch you all over! Your ass is so sexy and god I want to touch your pussy!!"

"Okay, that sounds good to me!" said Stacy. Janine froze, and Stacy gently caressed her ass as she came up to her.

"Stacy... what..." Janine had trouble organizing her thoughts, she was mortified at what she'd just been caught doing. She didn't know what to do.

Stacy giggled. "It's okay Janine, smell this!" she said, and shoved the pillow under her sister's face.

Suddenly the smell took over, and her irresistible urge to masturbate reasserted itself with a vengeance. Her fingers were a blur on her pussy and she bit down and sucked on a corner of the pillow with such a delicious smell. She felt the liquid inside the pillow as she sucked it in. It infused her body making every pore tingle.

Stacy took off her clothes and Janine watched, enraptured. With the hand that wasn't busy on her pussy, she reached out and touched Stacy's bald pussy. It was unbelievably slick and wet. Stacy pushed Janine into a lying down position, and managed to pull the pillow out of her mouth so that she could initiate a deeply passionate French kiss. Janine writhed in pleasure, her hand continuing to rub her clit. Her other hand ran over Stacy's body, fondling and kneading her breasts, pussy, and ass in turn. Stacy also fondled her sister's breasts and ass, although her pussy was blocked by Janine's hand. She wrapped her thighs around Janine's leg and humped while she groped and fondled her ass, and alternated between deeply kissing Janine's mouth and slurping on her succulent breasts.

Janine came really hard and really loud. She shuddered and moaned and Stacy held on for dear life as her sister suddenly became a bucking bronco. Stacy wanted to let go and cum too, but with a supreme force of will she managed to hold back. Her pussy was already lubing up all over Janine's leg, it wouldn't do for her to get her girl cum all over Janine's room and constantly drive her to distraction.

When it seemed like Janine's orgasm had calmed down, Stacy pulled herself away from her sister and grabbed her clothes. She looked at Janine. "Hey sis, do you remember what just happened?" she asked.

Janine looked up blearily. "Did something just happen?" she yawned. "I'm kind of tired, why don't you tell me about it later." she said sleepily, and then she lay her head down and began snoring. So it was true, a large dose of her pheromones would lead to memory loss after the recipient had orgasmed.

She pulled up her sister's pants and panties, making sure to get a good final feel of her ass and pussy as she did. She even kissed Janine's pussy before she pulled the panties over, licking a little to get a taste of her sister's girl cum to fuel her own fantasies. Then she put a blanket over the sleeping girl, grabbed her pheromone soaked pillow, and quietly left.

Stacy went back to her room and just stood there absorbing everything that had just happened. It was all unreal! How could her pussy juice have such an incredible effect? Was this okay? Was what she was doing like drugging people? Somehow, she didn't think so, but she couldn't figure out why not. Maybe it would be a good thing for her to refrain from masturbating in school until she figured this out though. That was going to be hard, she got the urge to masturbate in school several times a day and was very good at finding ways to excuse herself to go and take care of her horny pussy. But things were starting to happen that she didn't understand she was just going to have to bear with it until she figured it out. She'd have to spend a lot of extra time masturbating at home and hopefully she could wear out her pussy enough that it wouldn't be too hot and bothered at school.

She wasn't going to be able to help masturbating before going to bed tonight, her clit was hard and pussy juice was dripping down her legs almost in a constant gush. She threw her clothes to the floor (she hadn't bothered getting dressed after leaving Janine's room) and plopped down face-first onto the bed, her hand already massaging her clit from underneath. Stacy didn't know that many of the girls in her class were very attracted to her and had masturbated to her image almost as much as she masturbated to all of theirs. If any of them were in her room right at that moment they'd have been in heaven watching her bare ass grind against her hand, her hips swiveling sexily as her fingers massaged her bald little pussy with a passion.

She moaned and whimpered, and her movements got faster, her breathing got rougher, and her body tensed up as she came with a long, shuddering moan. Her toes curled and she writhed and jerked and her bed sheets got soaked with girl cum. Then she whimpered and shuddered a few more times until her breathing calmed down and she sat up with a sigh.

Maybe she should get some food, she thought. Her mother was working late so the girls usually grabbed their own dinner. She was really thirsty, she'd probably lost a lot of fluids cumming so much. She got up off the bed, but then she felt her pussy start to tingle again. "No way!" she thought, "I just came soo much! What will it take for my pussy to calm down?"

She tried to ignore it and threw on a bathrobe. She went to the kitchen, gulped down several glasses of cold water, and wolfed down some leftover chicken before making her way back to her room. She sat down on her bed and clenched her fists as she tried to ignore the ache in her pussy. She was going to need to get in the habit of doing that at school, and she wanted to know how long she could hold out.

Her fists clenched and she tried to not think sexy thoughts, but it was like asking somebody not to think of an elephant. Images of her naked classmates and of her sisters floated through her mind, and it wasn't too long before her hands were massaging her pussy desperately again.
