Harmless Effects

What could be more awesome than spending an entire weekend with Daring Do and exploring lost temples? Getting to do all of that AND being trusted by Daring to hold on to one of the artifacts found on the expedition.

Rainbow Dash currently sat on her bed staring at the strange object in front of her. It looked like such a simple thing, just an amulet with plain metal chaining and a small,pink gem attached to it. According to Daring, there was a legend that the artifact had the ability to grant its wearer increased stamina and charm along with other benefits. Naturally Dash wanted to try it out, but Daring had explicitly forbidden it.

“You know the dangers of messing with ancient relics, Rainbow Dash. They never quite do what you expect of them, and most of them will trick you.”

Maybe Daring had a point, but the allure of curiosity was just so powerful. The longer Dash looked at the amulet, the more she wanted to put it on. She needed to get it out of her head. She stood up and began getting ready to go out for a jog, but as she looked back at the amulet sitting on her table it seemed to call to her.

Surely one use couldn’t hurt…

She slowly reached out her hand and donned the amulet. Immediately when she did she could feel an intense amount of energy course through her. She felt amazing! She could probably do double her usual workout routine and still not be worn out. This was way better than any energy drink. She had to go try this out.

As she walked out the door she had little idea the trouble she was about to cause for herself and those around her…

Rainbow Dash was barely panting as she completed her third run around the block. This amulet was amazing! Why was Daring afraid of it? There was nothing wrong with giving yourself a little magical boost once in awhile.

As she completed her fourth lap she noticed she was starting to feel a bit hungry, which she shrugged off as being do to all the exercise. She went back inside her house and grabbed a couple granola bars before plopping down on the couch and starting to eat. She could probably take the amulet off now since she was done exercising, but found herself not really wanting to do that for some reason. It’s not like it was hurting her or anything. Daring only asked her to keep an eye on it for a week. What better way to keep an eye on it then to wear it, right?

After about an hour of watching TV and snacking she left the living room and headed into her bedroom. She began to strip down out of all her clothes, minus the amulet, and was in the process of putting on her pajamas when she felt the strange urge to just sleep naked for the night. It wasn’t something she’d usually do, but it was hot tonight, and it’s not like anyone could see anyway. She did a few stretches before laying her naked body on the bed, quickly falling asleep and being completely unaware as the amulet began to radiate with energy.

She woke up the next morning feeling completely energized. That was the best night of sleep she had gotten in a long time! She quickly began to put on some basic clothes, but was surprised to find the task a bit more of a struggle than usual. Her panties clung a bit tight to her hips and rear, and she had to actually put a little effort into making her bra snap on. She found it all a bit odd, but simply assumed that the clothing must have shrunk in the wash or something. After getting on a pair of jeans and a t-shirt she headed back into her living room to get some breakfast. Her appetite was still strangely high, so she found herself whipping up a much larger meal than she’d usually start the day with. That was alright though, she had a big day ahead of her. She was going to head over to Applejack’s farm to help her out with some errands, and then all the girls would be gathering for lunch.

After a quick meal she was out the door and jogging towards Sweet Apple Acres. It was only a couple miles away, and she’d take any excuse she could get for some exercise. It was probably for the best too, considering how much she’d been eating as of late.

Thanks to her newfound energy she was able to reach the gates of the Apple family farm in record time, and still had zeal to spare. She didn’t get far before Applejack came out to greet her.

“Howdy, Rainbow!” Called Applejack, wearing her usual country outfit, complete with the cowgirl hat, “You’re here earlier than expected.”

“I just wanted to get an early start so we can get the boring chores done and might up with the others”

“Uh-huh. Awfully generous and ambitious for the Rainbow Dash I know, we’ll see if that holds.”

The two quickly got to work with the farm chores. Putting up fences, feeding pigs, working in the barn. It was all pretty usual, what was unusual was Rainbow Dash actually being able to outpace Applejack at all the work. Both mares ended the work hot and panting, but they were done long before they expected.

“I gotta hand it to ya, Rainbow, ya really worked hard today,”complemented Applejack.

“Heh. Well...it didn’t seem too hard,” oddly enough, Dash’s muscles weren’t really hurting, but she still felt really hot for some reason. She couldn’t shake the thought that maybe it would feel better if she stripped off some clothes. She quickly shook the thoughts off though, not quite sure where they came from.

“Uh-huh. Well, let’s go meet up with the others than, since you’re so eager.”

Applejack and Rainbow Dash met up with their four other friends, plus Spike, at the cafe in the center of Ponyville. Everypony was busy enjoying their tea, hayburgers, and cakes while catching up on the latest events. Although Rainbow was much less active in the conversation than usual. She was distracted by a strange itch between her legs, and her mind constantly wandering towards more lustful thoughts. She found herself staring at any attractive colt or mare that crossed her path.

She saw a well-muscled colt walking nearby, one who was hiding a noticeable bulge within his pants. A second later her mind was filled with the image of that stud bending her over one of the cafe tables and rutting her senseless. Meanwhile everyone around her would watch in shock as she stood there with her panties around her knees, taking it like a total slut.

Dash found her hand moving down towards her pants, fumbling with the button and zipper. She didn’t have enough time to clear her head before another fantasy was triggered when a rather curvy mare walked near her. The mare’s shirt was bulging with heavy breasts that bounced and jiggled with every step. Meanwhile a very fat rear filled out her jeans and then some, causing her plump cheeks to bulge out and expose the upper part of her panties. The sights filled her with a strange sense of jealousy. She couldn’t help but wonder what it would be like to have big, bouncing jugs of her own. It also made her wonder how fun it could be to have a butt so unashamedly large she couldn’t properly fit into her pants, and it would draw the attention of anyone she walked by. It would be so amazing to have such big,plump curves that she could use to show off to others and make them-

“Rainbow, what are you doing?”

She jumped, suddenly snapped back into reality. All her friends were looking at her with confusion and shock.

“Uh...what’s going on girls?” Asked Dash normally.

“We should be asking you,” responded Twilight, “You were looking REALLY out of it there”

“Oh...uh...sorry, just got distracted thinking about things,” Rainbow responded, laughing awkwardly as she quickly zipped and buttoned her pants back up under the table. She only now realized what she was about to do in the midst of that fantasy. She almost masturbated in public! What was wrong with her?! ‘’

“Uh-huh…right,” replied Applejack, looking at Rainbow Dash with suspicion. Dash merely responded with a nervous smile and tried to get back into the flow of the conversation, although it was hard to concentrate after those bizarre fantasies she was having prior. She eventually ended up leaving the lunch early and heading back home to collect her thoughts.

As she entered her home she quickly went to the bathroom and began splashing her face with cold water.

“Get ahold of yourself, Dash. You aren’t some crazy girl who starts fantasizing and fingering herself in public.”

Yet the thought of doing just that was somehow enticing. She shook her head and thought that maybe a nice hot shower would help clear these strange urges. She stripped out of her clothes, leaving only the amulet on. She went to take off the amulet, but for some reason found herself really not wanting to. After a brief argument with herself she decided to just leave it on for now, not like it was hurting anything.

She turned the water to a nice, steamy setting before stepping inside and letting it flow over her naked body. It felt so good to just strip down and relax after such a stressful start to her day. Here she didn’t have to worry if she started fantasizing and wanted to pleasure herself a little.

“You don’t have to be embarrassed if you think about bending over for some stud and taking a good pounding,” she thought to herself while starting to slip a hand over her belly and down towards her crotch.

“You don’t have to be embarrassed about wanting a big shuddering rack to make all the boys, and even the girls, ogle.” Her hand then made it’s way over the lips of her marehood, and she began to slowly rub herself while letting out a light gasp of pleasure.

“You don’t have to be embarrassed if you want to strip off all your clothes in public, putting on a nice show for everyone to watch as they please themselves to your body.” She stuck an exploratory finger into her nethers, allowing herself a few moans as she began to gently thrust the finger in and out.

“How nice it would be to have a body so sexy that you’d always be the center of attention.” She began to imagine herself with big, heavy breasts, ones even larger than Fluttershy's. She pictured sporting a round,plump rear that bulged out of any pants she tried to contain it with. It encouraged her to stick a second finger into her slit, going at herself even harder than before.

All sorts of lewd,sexual fantasies began to fill her mind as she leaned back against the shower wall and continued masturbating. She imagined herself taking various males from all sorts of positions, fingering herself harder and harder as the fantasies became more intense. Her moaning and panting filled the shower, louder and louder, until she let out a final girly squeal and her body convulsed with an almost electric feeling of pleasure.

Rainbow slumped against the shower wall, panting lightly as the water continued to flow over her. That was the most intense orgasm she had ever experienced in her life, and it left her so exhausted that she almost didn’t notice the amulet glowing lightly with some type of energy. A brief feeling of worry surged through her, but she quickly shrugged it off. Whatever this amulet was doing, it all seemed to be positive effects so far. If it was harmless, why worry about it?
