“Cock-a-doodle-doo” The rooster announced at Sweet Apple Acres once dusk had come around. Three fillies had just arisen to in the Cutie Mark Crusaders HQ (a.k.a. the clubhouse) and were well rested from the sex high they felt yesterday.

“Girls,” Scootaloo spoke, “I think that we need to find out some more on that thing we found in the cave yesterday.”

“Ah agree. We need tuh find out more from a book or ask our sistuhs” Applebloom responded.

“Oh no! My sister’s gonna flip when she sees or hears about it. She might even gossip about it to the point of where all of Ponyville knows. What will we do then?” Sweetie Belle said with slight fear in her voice on what her sister might do.

“Sumthin’s been botherin’ me lately though. Are we considered freaks now?” Applebloom questioned.

“I guess we leave that up to one of Twilight’s books or our sister’s response” Sweetie Belle replied.

“We each should go home and eat breakfast but telling our sister’s about what is going on so we can then get their opinions first. We’ll then meet up near Twilight’s house so we can go and see if there is a book on what we are now experiencing.” Scootaloo stated.

With that all of the CMC were off. Sweetie Belle went home with the same kinds of questions in mind. What would her sister think? What would she do if she was kicked out? Would she leave Ponyville? The overthought questions were flowing through the young unicorn’s mind at a fast pace. She eventually reached her sister’s shop, the Carousal Boutique.

“The sign on the door says out for lunch. I guess she had to pick up something somewhere because she is never out eating. It makes her fat, she says.”

Walking in, she immediately realized that her sister left a usually refined and well kempt place an atrocious mess. Fragments of cloth were scattered everywhere and spools of thread lay halfway unrolled. Whatever the mess may signify, there, however, in the pure brightness of the sun through the shades, is the ensemble that Rarity worked extensive hours to complete.

“She must have worked really hard. I wonder how much stress she has been going through. I should probably help clean up. I have been working on levitation for a while now.”

Sweetie Belle was able to clean up the lighter spools of thread and smaller fragments of clothing but was unable to lift the heavier fragments. She was forced to use her mouth to pull the fragments away.

After a few minutes of waiting for Rarity to get back, Sweetie Belle went into the kitchen to eat a simple apple instead of trying to make something. She learned her lesson from the last time she tried to cook something and her skills (or lack thereof) have not gotten better. While waiting, Opalescence came in looking up at Sweetie Belle with a hungry tummy on its mind. If Sweetie was good with animals like Fluttershy, then she would know that Opal wanted food. She, however, took the slight movements towards Opal’s bowl as a sign that she wanted to play. A few scratches later from Sweetie Belle trying to force Opal to play and Rarity still wasn’t home.

Sweetie Belle decided to clean off in the bathtub to scrub the scratches and make sure that her scratch marks wouldn’t get affected.

“Dangit Opalescence! Why did she do this to me?”

“My, dinner was lovely, Fluttershy, after that spa treatment. We need to have dinner at that restaurant more often” Rarity said in a sing song voice.

“Oh, okay. We can. Oh my Celestia! I just remembered I have to feed the nocturnal animals for breakfast.” Fluttershy spoke in her quiet voice.

“Oh well then ta ta darling. I have to go feed Opalescence and check in on Sweetie Belle. She had better be home. I believe she had a sleepover at Applejack’s but I never found out. I hope for the best. Opal can be very, uh, scratchy when she is not fed. Bye.” Rarity said while opening the door and letting Fluttershy be on her way before going inside. “It’s so nice of Sweetie Belle to clean up for me after finishing that big order. She fed Opalescence and went upstairs to go check up on Sweetie Belle who was sweating in her bed after falling asleep waiting for Rarity to come inside of her room and kiss her goodnight.

Sweetie’s hermaphrodite penis was slowly rising from a rather steamy dream where she was taken from behind by a rather large stallion cock. She was being pile-driven into the ground. The only thing able to be seen was the size of the colorless penis and the colorless hooves holding her upper back to force her barrel down and her rump in the air. This level of submission to her attacker was making Sweetie’s fluids waterfall and was keeping her own cock as hard as a rock.

Rarity opened Sweetie Belle’s door quietly and tip-hoofed her way up to Sweetie’s bed and leaned down to kiss Sweetie’s head and when she came back up is when she noticed the increase in elevation of the covers. Rarity moved the covers away to get a better look at the object forming the mound in the covers. Her immediate reaction was to scream but that would wake up the neighbors and her sister. The follow-up reaction was to touch it with her hoof. Once she did this, she witnessed it twitch and squirt some pre onto her hoof.

Rarity then started to stroke it forgetting it was attached to her sister and forgetting that the mentioned sister could wake up at any second. Rarity finished sliding her hoof along the appendage and took a big whiff of the musk it was giving off.

Sweetie Belle was having the time of her life. She was now in the attacker’s basement/cellar. She was strapped to an old harness that would force mares to stay still for stallions. She had a cock ring and a gag inside her mouth. Her butt had anal beads stuffed to the ring of her anus. She was still receiving the pounding of the stallion cock from earlier but this time now there is a colorless horn with a grey aura surrounding a riding crop that is mercilessly whipping her rump.

Rarity was drawn out of her trance like state to her sister moaning and then spurting her thick femcum with most landing on herself or the bed but some landing on Rarity’s muzzle. Having to now wash her muzzle with a towel, she retreated to the bathroom when Sweetie Belle was fluttering her eyes open.

Sweetie Belle unfortunately was having a horrible nightmare after her wonderful dream of getting sexually dominated. She was tossing and turning until finally waking up and she did not want to go back to sleep. She wanted her sister next to her, a habit she had not grown out of yet when she got scared at night.

Rarity was sleeping soundly when the door opened with a squeak. She felt a soft voice asking if she was awake. Pretending like she did not do the ludicrous act with her sister, she acted sleepy and pretended to yawn. “Sweetie Belle, what do you need?”

“I would like to sleep in your bed. I had a bad dream. I know I am older now but just this once, for old times’ sake?”

“Alright darling, just remember to stay to your side.”

“Okay Rarity. Actually, if you don’t mind, I want to ask you a question first.”

“Go ahead Sweetie.”

“I developed a certain extra appendage on a Crusade yesterday and I was wondering if it was freaky, or more importantly, am I a freak with it?”

“Let me see it darling.” Rarity had a feeling she knew what she was talking about having caused it to cum in her sister’s bed.

Sweetie Belle then proceeded to jump up onto her sister’s bed and tilt her rump up showing Rarity the appendage near the end of her barrel. There it was. Sweetie’s beautiful penis was still slightly glimmering from Rarity’s saliva from not much earlier when she sucked it off.

“Sweetie darling, there is nothing wrong with that. It even is bigger than colts and a few stallions, if not most. This is something to be proud of for sure.” Rarity told an eager Sweetie Belle. “Have you used it yet though?”

Sweetie blushed. Was she to tell her about her friends having one also or should she say she never had urges yet? Worried the others would be offended if she did, she lied. “I haven’t used it yet but I have had wet dreams before.”

This was Rarity’s chance to ask her sister what her dreams were about. Sweetie Belle, what would those dreams be about. I promise I won’t find it repulsive in the least.”

‘Oh no, I may have caused Rarity to act differently. She seems to want to mention something a way to help maybe, but maybe I should answer her question if I want to get my answer.’ “Rarity, I dream about . . . being dominated.” ‘I can’t believe I said that. Wait, she’s smiling.’

Rarity was dumbfounded at first. Her elegant sister took sexual pleasure in being made a common whorse. ‘This might be fun then.’ “Sweetie darling, it is perfectly fine with what you enjoy. In fact, I have some toys under the bed if you want to be dominated in real life. That is what I enjoy, dominating others. This could be fun.”

After witnessing a smiling Sweetie Belle nod, she used her magic to bring out a cardboard box labeled “Rarity’s Box of Fun” and prevented Sweetie Belle from seeing the inside. She pulled out a long double-sided dildo with a black leather strap near the middle, a riding crop, some rope, and a smaller dildo in the shape of a narrow egg with a spread out flat back. She then placed one end of the long dildo inside of her pussy causing a subtle moan to escape her mouth. After applying the fastenings around her waist, Rarity turned to show Sweetie Belle her new cock. Measuring up, her dildo jutting out of her vagina was thinner than Sweetie’s cock but it was definitely longer.

“Please lay on your back Sweetie.” Rarity told Sweetie to do. Rarity then lowered down and gave her cock a lick with a little sucking on the head before she took Sweetie’s virginity from under her. Rarity allowed Sweetie to adjust to the dildo. This is how their night of sex went. Rarity tied her sister’s hooves together, hit her rear with the riding crop, roughly shoved the strapon inside Sweetie’s butt hole and put the smaller dildo inside when she was done. The final orgasm that the two had was at the same time, a feat hard to accomplish. Rarity was shoving her sister’s cock inside of her pussy while using her magic to hit Sweetie some more. Sweetie, feeling daring, used her magic to tingle Rarity’s clit. This caused Rarity to scream/moan and Sweetie to be hit hardest of the night. After all of that sister bonding time, they both went to sleep inside of Rarity’s bed and had a very peaceful slumber while cuddled up.

Author's Note

That took longer than expected. From school to vacation (no internet) I wasn't able to post this. Sorry for the wait for all of those who were waiting for this waitable story being waited upon. I think you get the gist of it. Til next time when Rainbow Dash has her fun with Scootaloo.
