How do two loving sisters ask their crush, Rainbow Dash, to join them for a threesome?

Cloudchaser and Flitter have loved each other for some time now and are definitely more than just sisters. They have been having a lot of fun together at their house in Cloudsdale every week.

It gets interesting when both of them have a crush on one very specific pony, Rainbow Dash. They want to try and add her for at least a one time thing for experience, but how would they be able to talk her into it without making it awkward? Will Rainbow Dash accept or decline? How would the three of them feel about a threesome?

If Rainbow Dash does end up accepting, how will things turn out? Will it be more or less awkward? Are they going to end up having the time of their lives? Most importantly, who's going to be in charge?

Threesome Fun?

Flitter and Cloudchaser were holding each other on their bed while they waited for Rainbow Dash. They had recently invited her to come over to their house since they had something to discuss. It would be awkward to discuss, but it had been too long and decided to ask her today.

The two sisters had a major crush on not just each other, but also on Rainbow Dash. They had loved everything about her: her toned body, skills, features, and personality. They wanted to ask her if she wanted to join them for fun on their bed. They usually just did it with each other since they were loving marefriends, but they also wanted to explore their sex lives a little further. They had both agreed upon inviting Rainbow Dash over to see if they could have a threesome, something that would definitely be awkward to talk about.

"You think she'll think we're freaks?" Flitter nervously asked while cuddling her sister in bed.

"I hope not. Although, I wouldn't blame her if she did think we were. I just love her so much. Hopefully, she would be willing to spend time with us." Cloudchaser finished with a sigh.

After a few minutes of waiting for the pegasus' arrival, they heard a shout outside. They knew who's voice that belonged to and flew through the cloudy window to see the pegasus standing outside. They gestured her to come in and they went towards their bedroom. The sisters sat back on the bed while Rainbow Dash stood next to them.

"So, what did you girls want to talk to me about?" Rainbow asked in a happy tone.

The two sisters nervously looked at each other before speaking up. "It's just something we've had for a while," said Flitter. "You know that we're marefriends and we love each other very much. We just wanted to ask a quick little favor from you."

"I don't mind you two being marefriends. I find it quite cute. What favor did you want to ask from me?" Rainbow asked very curiously.

Both sisters started to look red in the face. What was going to be the best way of telling her?

After a few seconds of pure silence while Rainbow started to have a nervous look, Cloudchaser decided to just let it out there so they could move on. "I don't know if you've known, but there are some times that we... have fun."

Rainbow wondered what this could mean but couldn't think it was possibly what she thought of. She gave a nervous reply. "You don't mean... actually doing it with each other, right?"

Flitter looked at Cloudchaser before turning back to face Rainbow with closed eyes and a timid response, "yes."

"Why did you feel the need to tell me that? You girls didn't have to let me know if it makes you uncomfortable." Rainbow was confused as to why they told her they had sex together. What was the point?

"Well, we wanted to invite you over to... try it... with us." Flitter was very quiet at letting her know that they wanted Rainbow to join. How could you not feel scared about it?

Rainbow's face went wide in shock. They literally asked her if she wanted to join them for sex. She didn't know whether to feel amazing or awkward. She just stood at the edge of the bed while trying to process the information.

She was so lost in her thought that she didn't even realize the two sisters departing and making their ways to both sides of the shocked pegasus. They were positioned so that Cloudchaser was on the left of Rainbow and Flitter was on the right. They both wrapped their forehooves around her and nuzzled her cheeks.

The cyan pegasus was blushing a noticeable shade of red. She didn't know how to feel about the situation. She liked the two very much, but to be in a situation about them wanting to have sex with her and doing it right this moment was next level.

"We both have a crush on you, Rainbow Dash. We really want to have another sexual experience but with you added in the mix," Flitter attempted to be as seductive as possible to further increase the chances of it actually happening.

Rainbow had a lot of things going on in her mind. Flitter and Cloudchaser have a crush on her? Was this reality or a dream?

All of a sudden, she felt Cloudchaser starting to give small kisses on her cheek while Flitter kept nuzzling and speaking softly. "Please, Dashie? We literally love you so much."

Their cuteness eventually won her over and she finally agreed to try the fun with them. "Alright, this shouldn't be too bad. Maybe it will be fun."

"Oh my gosh, thank you so much, Dashie!" Both sisters exclaimed in unison. They grabbed her and pulled her onto the bed. The fun could now officially begin.

"Whoa, you girls seem pretty eager to be doing this." Rainbow gave a small chuckle at how much they wanted her to be a part of the fun.

Flitter just grabbed Rainbow tightly while talking all happily. "Rainbow, this is like a dream come true. You are so hot. I wish I could be as hot as you."

Rainbow gave another chuckle. She really was hot, wasn't she?

"Okay, let's calm down. These kind of sessions are supposed to be relaxing, not all excited and loud." This made Flitter let go and give a smirk to her sister. Cloudchaser smirked back and they both smirked at Rainbow.

They cyan pegasus went from a smile to nervousness. Why were they smirking at her? "Um, why are you girls giving me those looks?"

The sisters adjusted their positions so that Rainbow was lying on her back with them on both sides of her. Flitter started to lick all over Rainbow's chest. The athlete started to softly moan at the sensation.

While all of this was starting, Cloudchaser leaned in towards Rainbow's left ear and nibbled on it gently. Rainbow's breathing and moans started to increase as she started feeling a wetness around her lower area.

Then, Cloudchaser spoke very seductively. "Are you going to be a good girl for us?"

This got Rainbow worried. What did she mean? Was something bad going to happen if she wasn't a good girl for them? She nervously started to speak while still moaning and breathing heavily. "What do you mean? I thought we were all equal here?"

"Far from it," Cloudchaser continued. “Flitter and I are in charge. You are going to be our extra presence for us to play with. We've both had a crush on you for the longest time. Everything we do is straight from our hearts. Just enjoy the moment, okay?"

"Okay," Rainbow softly whispered.

Cloudchaser leaned her lips forward towards the lips of the cyan pegasus. Once Rainbow felt the lips, she began to move in sync with her partner.

Cloudchaser pulled away to say something to Rainbow before reconnecting. “By the way, we’re not going to be the loud ones today. You are going to be the loud one.”

Rainbow wasn’t sure what that was suppose to mean. “What do you mean I’m going to be the loud one?”

This formed a smirk for Cloudchaser. “Nothing.”

She started the kissing session again to change the subject.

Flitter began to move from Rainbow’s chest, trailing down. She kept licking all the way down until she saw what she was looking for. She started to nibble on Rainbow’s pussy that was covered with her wetness.

The athletic pony started to feel weak and went limp. She was moaning and breathing a lot more heavily into Cloudchaser’s mouth. Cloudchaser wrapped her hooves tightly around Rainbow’s neck and shoved her tongue forcefully inside.

Flitter started to suck her crush’s pussy a lot more vigorously. This got Rainbow to pull her lips away from the kissing and let out loud moans.

“Ahhhhh! Oh my gosh. You girl are so next level with this.”

Flitter stopped sucking on Dash’s pussy and put on a smirk. She moved up so that her body was directly on top of her crush and that they were face to face. She started to whisper while Cloudchaser moved over to grab something from the drawer next to them.

“We promise we will make you feel good, Dashie. We will show you a great time that by the end of this, you’re not going to want us to stop. You’ll be wanting more and more. You will soon want to live with us and become part of our love life.”

Rainbow didn’t know what to say. She just stared into the eyes of the beautiful mare on top of her.

She was soon snapped out of her trance by Cloudchaser coming back towards them. What Rainbow saw made her eyes go wide: two strap-ons that had the same color of the sister’s fur.

She was too lost in her thoughts to notice that the sisters started to attach them to themselves. She soon realized they had them on and tried to say something but was stopped when Flitter placed a hoof over her mouth. “No need to speak, Dashie. The only things you need to say is how much you want more of this and how much harder you want to get rutted.”

Flitter moved her hips up the mare’s body until the tip of her dildo was just inches away from Rainbow’s mouth. The cyan mare took it in her mouth and started to go down on it.

It had been a while of trying until she realized that she had not yet reached the base. That was when she realized something that was both thrilling and scary. Both strap-ons where an entire foot long. It was the perfect size and shape of a stallion’s.

Cloudchaser moved around the back and aligned her cock with Rainbow’s aching pussy. The sisters both knew that Rainbow loved it rough. She didn’t even need to give Rainbow any warning as she thrusted in hard. Rainbow screamed around the cock in her mouth as she was starting to get taken.

Rainbow tried to say something but everything came out as muffles. She did have her hooves to use, but they were still limp. She couldn’t do anything but get taken by the sisters.

After some time of the same position, they quickly grew bored of it. There were many more positions they could be in that would drive Rainbow wild, one of them being so that they could double penetrate her.

Flitter and Cloudchaser got off and left Rainbow panting. Flitter moved to lay on her back while both sisters dragged the exhausted mare on top of her so that they were face to face. Cloudchaser positioned herself behind while they both started to line their cocks up with Rainbow’s two entrances.

There was no warning needed as both of them thrusted into the cyan pony's two folds. Cloudchaser had no worries since her cock was already lubed up from pounding Rainbow's pussy freely.

As they both went haywire on their crush, Rainbow kept moaning out loudly. She couldn't control herself and felt like she wasn't actually having sex with them. She was just being used to satisfy their wishes. She wanted to take some part of control but couldn't.

As the two mares continued pounding away, Rainbow could start to feel the rush of her orgasm coming. She wanted to try and tell them that she was close and didn't want to finish too quickly, but she couldn't find the words. It was hard for her to try and speak when she was constantly getting pounded senselessly.

The time soon came and she let out a loud cry of moans. It was so loud that anyone just a few yards outside from the house could hear what was happening without even looking. Rainbow's entire body tensed up as she squirted a lot of juices all over the three and the bed. She kept screaming out of pure bliss and decided to just let it all out. She didn't even care who could hear her.

After coming down from her high, the two mares pulled out and removed both of their strap-ons. Cloudchaser moved up towards Rainbow so that her pussy was directly above her face. "I hope you still have some energy left over, because we're not finished just because you had your moment. You still have to work to get us off."

Rainbow didn't even fight back as she started going to town on Cloudchaser's sweet pussy lips. The soft moans escaping Cloudchaser encouraged Rainbow to suck harder and try to bring her to her high. Flitter moved so that she was directly on the side of Rainbow, watching her suck up her sister's juices. She gave her cheek some kisses from time to time while running a hoof though her mane.

Rainbow was enjoying the sweetness and taste of the pussy she was currently eating out. She never imagined something like this would taste like heaven.

There came a moment when Cloudchaser couldn't control herself and started to harshly grind her pussy all over Rainbow's face. She was smearing her juices all over her crush and making the pegasus eating her out all dirty. The sisters knew she didn't care. She really did love it rough.

It was almost time for Cloudchaser's climax to happen. She knew what she was going to do with it. She kept grinding on Rainbow's face as she was being eaten out. After a few more seconds of constant grinding, she hit her climax. She pushed herself down as hard as she could until Rainbow found it hard to breathe. Huge amounts of cum sprayed all over the cyan pegasus' face and some even went inside her mouth. She swallowed what she could and repeatedly tapped on Cloudchaser's flank to show her that she needed to breathe. She got off about ten seconds later when she started to come down from her high.

Cloudchaser proceeded to lay motionless on the side of Rainbow while Flitter watched in complete shock. "Holy horses. You really did it to her, Rainbow."

Nopony said anything after that. Flitter could hear heavy breathing and panting from her sister and her crush. There was only one thing, though. She still needed to get off.

"Dashie, please don't be gone yet. You still have me, remember?"

Rainbow slowly opened her eyes to see Flitter coming on top of her. She needed to pull through just a few more minutes and get Flitter off. It would only be fair if all three of them had the orgasm of their lives.

Rainbow took in a few deep breathes before starting to lap up Flitter's juices. Her face and mane were a complete mess. It really did feel like they were just using her, but she didn't mind.

Flitter gave cute soft moans as Rainbow ate her out. Flitter seemed to be a lot nicer than Cloudchaser. She wasn't harshly grinding her pussy lips all over her crush. She just sat on top of her and let her go at her own pace, which seemed to be pretty eager.

Flitter soon came up with an idea. "Cloudchaser, can you lay on your back in front of me and grind Rainbow's pussy together with yours?"

Cloudchaser seemed to almost have no energy at all but liked the idea and proceeded to do so anyways. She laid on her back so that her pussy was directly in line with Rainbow's. She moved her left hind hoof under Rainbow's right and started grinding. This caused the two mares to moan loudly. Flitter dove in between their pussies and licked at them both simultaneously.

This caused increase in pleasure as Rainbow continued to eat Flitter out. Now, all three mares were getting eaten out at the same time. Rainbow seemed to be getting most of it since she was being eaten, grinded, and having to eat Flitter's pussy.

The time for Flitter to have her moment soon came as she started to moan louder. Rainbow took the opportunity to dive in and push her tongue all the way inside Flitter. This caused a scream of ecstasy from the mare as she clenched down on Rainbow's tongue. She started to spray her juices all over the exhausted mare just like her sister and get her even more filthy.

Rainbow couldn't be bothered to drink up what she could and simply just let herself be sprayed all over her face and mane. It was too much work to put into and she really did need a rest after all.

Soon, the grinding stopped and the two sisters turned around to climb next to the cyan pegasus. They snuggled up together and looked like they could just fall asleep any moment. Both sisters gave Rainbow a soft kiss on her cheeks and Flitter whispered, "did you enjoy that, Dashie?"

Rainbow looked like she was just about done. She tried to respond but eventually let sleep take her away. "I... I..." Too mentally and physically exhausted, she fell asleep right on the spot.

The two sisters gave each other a smirk and a hoof bump before saying in unison, "and that's what you call a threesome."
