Starting their Days
It was another morning in Ponyville and Rarity had woken up. Rarity was hoping to get a great amount of work done as she did have important orders to fill but something wasn't right, something was going on that would make that impossible. Rarity was going through a cycle of estrus. She sat up and groaned, "Ugh, why does this have to happen now? Why couldn't it wait until after I filled these orders?"
Rarity then got up and began to think about one thing, Starlight Glimmer and how incredibly hot she thought she was. She began to wonder that with her being in estrus, if maybe she could seduce her. She got a smile on her face, "Hmmm....I wonder what Starlight would do if I visited her like this? I wonder if she might want me?" She paused before adding, "Well I better get showered if I'm going to visit her."
Once Rarity got into the shower, she began to finger herself pretending that it was Starlight's horn going up in her. This was one thing that she had never dared admit to anypony, especially Twilight but she did find Starlight incredibly sexy and wondered what an experience with her would be like. Her shower took a bit longer because of her self-pleasing activity but once she was done, she headed into her closet and began to go through her clothes.
As Rarity was going through them, she knew that she would have to wear something that would expose her "assets" more. Rarity had no shortage of such kinds of clothes so she was easily able to find a snug fitting shirt along with a shorter skirt. She also decided to wear black undergarments that would stand out against her coat perfectly. She said to herself, "Excellent Rarity, once she sees you like this, she will find you irresistible!"
Once Rarity got dressed, she headed towards Twilight's castle. She wasn't sure what Twilight would think of her visiting them in the state that she was in. Normally she would consider doing such a thing as uncouth and not lady like but her desire for Starlight was too great, she wanted her too badly to be lady like.
***
That morning Starlight woke up and the moment she came to, she was frustrated. She could feel it, she could feel that she had gone into a state of estrus as she was suddenly feeling needy. This was something that did not happen with her nearly as much as it did with her friends since she had found ways to focus on other things but this time the feeling felt much stronger.
"Ugh," she groaned "why must this happen?"
She was sopping wet and this frustrated her further as not only was she going to have to use scent cancelling soap but she was also going to have to wash her bedding sooner than normal. She had her concerns as to what Twilight would think because she had just washed it yesterday. She sighed, "How do I explain this to Twilight? Nopony does anything to require their bedding being washed on consecutive days!"
Starlight first though headed to the shower to get herself clean and most importantly, get that scent washed off. The last thing she wanted was for her to be releasing a scent that would cause others to think she was wanting to engage in intercourse. As she was in the shower though, she began to finger herself and started thinking about a certain fashionista who she had found attractive for quite some time.
She began to gently moan before snapping at herself, "Come on Starlight, Rarity would never want to get it on with a pony who stole her cutie mark! You know that she probably isn't into mares!"
Starlight then began to used the right soap to cover her scent up for the whole day and got herself fully clean. Once she finished, she decided to dress more plainly than normal. Starlight normally wore a t-shirt along with jeans but that day she chose to wear sweatpants along with a looser fitting shirt given that her nipples tended to be hard when she went into estrus. She also chose her typical sports bra to hopefully hide her rock hard nipples. Once she got dressed she said to herself, "Alright, now to let my sheets dry and then get them washed."
Starlight then headed down to breakfast and noticed that Twilight was dressed like she did on most days, similar to how she dressed, jeans and a t-shirt. When Twilight saw her dressed like that she got a smirk on her face, "That time huh?"
That was one thing that always made Starlight nervous, was that Twilight could always tell when she had entered estrus. Starlight nervously replied, "Uh...."
Twilight approached her and began to sniff. When she smelled absolutely no scent coming from her friend at all, she knew. She snickered, "You know you don't have to hide your scent like that! I don't when this happens and besides, Fluttershy is the only one who approaches me over it!"
Starlight sighed, "I know but everypony else knows not to approach a princess over that and besides, they also know that you and Fluttershy are closer than most friends anyway!"
Twilight snickered, "True, you do make a point so I can see why you hide your scent." She heard Starlight's stomach growl and added, "How about we have some breakfast?."
Starlight agreed and after Twilight prepared the two breakfast, the two sat down to eat. While they were eating Twilight gave Starlight a smile and asked, "So what are your plans for the day?"
Starlight groaned, "I'm hiding out until this is over! I always hid out in my old village and you know I hide out here! I can't go out in public like this, what if my scent was detected by somepony?"
While Starlight entered into estrus far less often than most mares in Equestria and she could contain her urges much better, when she did her scent was stronger and it lasted much longer for her. Twilight sighed, "But Starlight, you have that soap that hides your scent. You went out and about last time!"
Starlight groaned, "But the scent is worse this time, what if my soap quit working early?"
Twilight sighed, "Well that is true and I know how self-conscious you are....well that and that you've never wanted anything like that to start....."
Twilight's sentence was interrupted by a loud knocking on the door. Twilight continued, "Well let me go see who that is, hopefully it is just one of her friends."
Starlight screamed, "I'm heading up to my room, what if they smell me?"
Starlight rushed up to her room while Twilight headed to the door. As she headed to the door, she couldn't help but feel bad for Starlight. She knew how she was, she knew that she was the only one that Starlight felt comfortable around when she was going through this. She sighed, "Hopefully whoever it is won't want to be here for too long."
Two Mares in Heat
Twilight approached the door and opened it to discover it was Rarity. Twilight stood to the side and allowed Rarity entry. Once Rarity was inside Twilight asked, "Oh hi Rarity, what brings you by?"
Rarity was blushing deeply as she asked in return, "I was wondering if I could talk to Starlight?"
Twilight approached her and began to sniff. She could easily pick up on Rarity's scent and knew what was going on. She did know one thing, she knew that with Rarity going through what Starlight was, that Starlight picking up on her scent could very well wind up in the two getting intimate and wasn't sure if Starlight in her normal state would want that. She didn't want to make Rarity suspicious either. She replied, "Yeah, she is up in her room."
Rarity asked, "Can you show me where it is, I've never been to it before?"
Twilight nodded and led Rarity up to Starlight's room. Once they arrived Twilight knocked on her door, "Starlight, open your door, you have company."
Starlight screamed, "No, I don't want anypony to see me like this!"
Rarity gave Twilight a strange look prompting her to say, "Rarity, Starlight is well, uh, how do I put it, she is going through...."
Rarity got a huge smile on her face, "Estrus darling?"
Twilight replied, "Yes and I don't think you two should be together. Starlight in her normal state would never want intimacy but with both of you going through this, she'd do things that she might regret later."
Rarity asked, "Twilight, can I tell you something and you promise you won't tell Starlight?"
Keeping secrets was something that Twilight wasn't exactly all that good at but agreed, "Yes, you can."
Rarity began, "Twilight, I have a crush on Starlight and when we went on that retreat, she smiled when she learned that I missed the comforts of home! She might want it but is afraid to admit it."
Twilight sighed, "True." She then yelled, "Starlight, it is just Rarity. It will be ok!"
Starlight was unsure what to think when she heard who it was. She did find Rarity incredibly attractive, sexy to be more accurate, but feared what Rarity would think if her scent was so strong she could detect it or if Rarity was to smell it radiating from her now dry sheets. She finally decided to take the chance and used her magic to open her door. Rarity walked in to find a clearly nervous Starlight sitting at her desk.
Rarity approached her and asked, "Starlight darling, I was wondering if we could talk?"
Starlight quickly picked up on her scent and she became more nervous, especially once cum began to flow from her and Rarity picked up on her scent. Rarity wrapped herself around Starlight and kissed her neck, "Starlight darling, I....."
The smell of Rarity was strong, very strong and it was quickly overwhelming Starlight. She began to think in a way she never did before as the other mare's scent was causing her hormones to take over her thoughts, "Rarity, could we, could we?"
Rarity pulled her up and pulled her to where they were face to face. She kissed her and replied, "Starlight darling, I want this so bad, I want you so bad." She pulled Starlight into a deeper kiss and groped her flank before continuing, "Starlight, I need this." She then grabbed Starlight's shirt and ripped it off of her and pleaded, "Please Starlight darling, take me!"
Starlight ripped Rarity's shirt off of her and exclaimed, "Oh Rarity, I have to have this, we have to have this!"
Twilight was watching from the door and said, "Well I'm going to go out for a while and leave you two....alone."
Neither mare heard her and continued to rip the other's clothes off. Once they were fully nude the two pounced on Starlight's bed and almost immediately, Rarity found Starlight on top of her. Rarity immediately spread her legs so Starlight could grind herself up against her. Starlight knew what she wanted and immediately began to grind the white unicorn.
Rarity began to moan, "Oh Starlight, oh Starlight."
Starlight returned the moan, "Oh Rarity, oh Rarity."
The two then engaged in a passionate kiss as they began to grind their bodies more roughly, working up a quick and heavy sweat. As the two continued, their breathing became heavier and their bodies became hotter and more sweaty. This is something that both mares desired a great amount, a lover with a hot and sweaty body. Finally the two broke their kiss and their moans got louder and louder until the two climaxed simultaneously, covering the other with their juices.
After the two climaxed, Rarity gave Starlight a lustful look, "Starlight darling, I never imagined anything could feel this good!"
Starlight moaned, "Oh I know Rarity, I needed this so bad!"
The two then resumed their make out session and continued to grind their bodies together. Once they finally pulled their bodies apart, the two began to examine one another with a look of desire. Starlight's eyes were glued on Rarity's F cup breasts. She licked her lips and asked, "Rarity, can I taste them?"
Rarity exclaimed, "Please darling, taste them, suck them!"
Starlight immediately took to her left breast and began to massage the right one. Rarity began to moan gently and run her hands through Starlight's mane. Rarity however did not want Starlight to simply suck on her breasts, she wanted to provide her with a tasty treat. Rarity flared up her horn and cast a spell that caused her breasts to be filled with milk. Almost immediately she began to lactate and Starlight began to suck on her breasts with much more force.
Rarity began to moan loudly, "Oh Starlight darling, oh Starlight!"
Starlight's muffled moans became louder as she continued to feed off of Rarity. Once she drank her first breast dry she exclaimed, "Oh Rarity, I could drink this forever! It is so tasty!"
Rarity pointed to her other breast and suggested, "How about you take the other one too? After all, it isn't very nice to only drink from one!"
Starlight gave her a smile before taking to it. Once she began to drink, Rarity flared up her horn and cast another spell. The spell she cast caused Starlight's estrus to become more intense and would cause it to last much longer. As the enchanted milk began to affect Starlight, her desire for Rarity became much greater. Thoughts began to run through her mind wishing that her and Rarity could lay in bed forever and give one another the same pleasure they were.
Once Starlight had drank both breasts dry she gave Rarity a lustful look and suggested, "Oh Rarity, can we eat each other, can I drink your cum?"
Rarity gave her a smile, "Not yet darling, there is something I want to do."
Rarity flared up her horn and cast a spell on Starlight, causing her breasts to become filled with the same enchanted milk that Starlight had drank. Rarity knew that it would not be right for her to force an enhanced and prolonged estrus on Starlight without doing the same thing to herself.
As Rarity was consuming the milk, her hormones began to take her over further and her desire to do this increased exponentially. She continued to suck harder and harder as Starlight began to yank on Rarity's mane and moan, "Oh Rarity baby, yes, yes, yes!"
Once Rarity had drank Starlight dry, she pulled herself up to where she was giving her lover a look of pure lust. The two gazed at one another with a look of desire before looking down towards one another's marehoods. Without saying a word, the two got on their sides, lifted a leg up and immediately buried their faces in one another.
The two began to suck on one another violently and were probing the other with their tongues. As they continued to suck and probe, their moans got louder as they started to grope one another's flanks. While this was going on, Rarity flared up her horn again and cast a spell on both her and Starlight's cum. She cast a spell that would cause the two to be inseparable and not be able to go a single day without making erotic, kinky love.
As the two were moaning louder, they knew their climaxes were coming and both formed a tight seal around the other's pussy so that not a single drop of cum would go to waste. As they continued to suck, they tightened their legs around their lover's head and began to grind their bodies harder again causing a heavy sweat to build up. Finally they let out loud, muffled moans and they climaxed simultaneously. They very quickly consumed the other's sweet cum before continuing to suck and suck on one another.
Twilight's Discovery
After several more hours of sucking and multiple simultaneous climaxes on the part of both mares, there was a loud knock on Starlight's door, a knock that neither heard. Very quickly the door flew open and standing there watching the two eating one another was not only Twilight but Fluttershy as well. The moment Fluttershy saw them eating one another, she let out a loud shriek before fainting.
The loud shriek caused the two to pull their heads out of one another and look towards the door to discover Twilight standing there with her mouth hanging open. The two weren't sure what was running through Twilight's mind but Starlight figured she would at least say something, "Twilight, we can explain."
Twilight began to smile, "Oh there is nothing to explain, you put two mares in estrus together and things are bound to happen." She paused before slipping up and revealing Rarity's secret, "Starlight, Rarity has a crush on you!"
Starlight got a huge smile on her face, "Really Rarity, you have a crush on me?"
Rarity pulled Starlight close to her and replied, "I do darling and since somepony just had to spill the beans about my crush, I may as well ask." She paused before asking, "Starlight, would you be my marefriend?"
Starlight exclaimed, "Yes Rarity yes, yes I'll be your marefriend!"
The two began to kiss passionately and Twilight knew that there would be no way to communicate with them as this make out session would likely last quite a while and would be followed by an intense and likely very long session of love making. She closed the door and discovered that Fluttershy was beginning to come to. She asked, "Fluttershy, are you ok?"
Fluttershy wearily replied, "I am but I could have swore I saw Rarity and Starlight, well um...."
Twilight stated, "You did." Fluttershy's eyes grew wide as it began to sink in that Rarity and Starlight were engaging in an activity that she never once imagined. Twilight could tell that her friend was in a state of shock. She continued, "Well, both of them entered into estrus and spent a fair amount of time together and well, Rarity had a crush on Starlight and she likely felt the same way so that happened."
Fluttershy had always had a crush on Rarity and sighed in disappointment, "So is this just going to be an estrus thing or are they more?"
Twilight replied, "Well Rarity asked Starlight to be her marefriend and she said yes so even after this passes, they'll be an item." Fluttershy sighed in sadness and Twilight added, "Fluttershy, you know if you need to talk, I'll be here for you."
Fluttershy gave Twilight a smile, "I know you will Twilight and I really appreciate it." The two then heard Starlight and Rarity moaning and squealing and Fluttershy had to get out of there. She asked, "Twilight, what do you say we get out of here? I can't hang around and listen to that....maybe we could go to my cottage."
Twilight replied, "I'm with you Fluttershy and your cottage sounds like a great place to go."
The two left the castle and Twilight began to have a thought she had never had before running through her mind. She had always found Fluttershy sexy and did like like her but never approached her over it because of her closeness with Rarity. She then thought to herself, "That's it, I'll cast an estrus spell on both of us, a good strong one and then we can wind up just like Starlight and Rarity! We'll wind up being marefriends and lovers!"
