This is part 1 to a three part chapter. WARNING! CONTAINS FUTANARI, THREESOME, DIRTY WORDS, AND INCEST (INCEST IS WINCEST) The incest part will only be common in these three parts and will hopefully add a new idea for the futa fillies.

“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. Applebloom went to her house but her sister wasn’t home but she saw her brother in the field plowing away at the future cornfield. Big Mac was not a force to be reckoned with when he was angry (which he rarely became) or when he was defending somepony but he was kind at heart. Most felt that the big red stallion’s body was something of a handsome nature with his rippling muscles as evidence of multiple years of hard work. His dirty blonde hair and face were sweating from the work he was doing. Fur clinging to his body and muscles flexing from the plowing would be enough to make any mare go crazy for him. Big Mac was truly a unique specimen; one that many mares would tell you is the sole stallion of their sexual fantasies.
“Hey Big Mac, is AJ inside.” Applebloom asked Big Mac from the closes side of the field that Big Mac finished at.
“Eenope” Big Mac stated bluntly.
“She out in tuh field.”
“Eeyup.”
“When’s lunch time?”
“Soon.”
“Actually ah think ah see her. Thanks for yuh help Big Mac.”
“Welcome.”
Applebloom then left the short sentence stallion behind after witnessing AJ come out from the trees with multiple buckets. Applejack or AJ was like her brother in the mention of muscle mass ratio to her body. Her slim barrel and slightly muscular legs from her work on the farm has attracted a few stallions before, even big shots like Trenderhoof. She is not too big on fashion but she is beautiful without any make-up or fancy dresses. Applebloom approached AJ and said, “Sis, ah need tuh tell yuh somethin’.”
“Okay, but Big Mac will have tuh be der since it sounds like uhn issues dat needs adressin’. Granny Smith’s in Appleloosa so I will need uhnother set of ears.”
“Okay.”
After that short conversation, AJ, Applebloom, and Big Mac went in to eat lunch but it was brunch for the youngest apple. After a meal consisting of apple tarts, apple fritters, apple juice, and caramel apples for desert, thee three siblings went into the family room to talk about what was on Applebloom’s mind. AJ had told Big Mac that she needed him but that was the extent of their conversation. After Applebloom had planned out the events in her head, she decided to go ahead and start talking about it.
“What ah am about tuh say is sumthin’ that ah need da truth as a response only.” Applebloom began.
“Yuh have mine and Big Mac’s honest opinion” AJ responded.
“Eeyup.”
“Okay.” Applebloom then, after some arguing between both consciences, decided to just go with it. She then asked for her brother and sister to turn around for a little. When they hesitantly did so, she then proceeded to graze her hoof over her marehood to try and get aroused. Thankfully, her siblings never turned around until she told them to.
“Okay, yuh can turn around now” Applebloom said.
When her sister and brother turned around, they were expecting to be shown a bad grade or a bruise from being bullied. Instead they found a rather impressive stallionhood at full mast in front of them right above her moist marehood. The two were left flabbergasted and Applebloom sat with her eyes closed waiting for a response. The first pony she heard was AJ.
“How’d yuh get it?” AJ said bluntly.
“When ah was crusadin’ with Sweetie Belle and Scootaloo” Applebloom said. “Ah’m a freak, ain’t I?”
“No, that’s not it. It is a biggun. Dis may sound weird Big Mac, but is it bigguh den yurs?”
“Let’s see.”
Applebloom then sat next to Big Mac while AJ got off of the couch they were sitting on to get a better look. Big Mac started stroking his slightly aroused cock while Applebloom and AJ stared intently. He stroked and stroked and when close to full mast, started fondling his big stallion balls. His big red marebreaker was standing now taller and thicker than Applebloom’s. His little Big Mac was about 11” closer to a foot while the girth had about a 1” increase in diameter. AJ’s mouth dropped at her two siblings’ cocks with slight salivating out of her mouth. She couldn’t hold back any longer when their musk reached her snout. She reached out with her front hooves and touched Big Mac’s thick cock to straighten it up so she could take big long licks from base to head while giving the head a flick with her tongue. After a few licks, she moved her head slightly to lick AB’s cock the same way. After not feeling content by only licking, she told Big Mac to get behind her and prep her while she deep throated with ease Applebloom’s cock. Big Mac isn’t one to disappoint a waiting mare even with thoughts of this being potentially wrong in his head. He got down low. Entranced by the smell of her arousal, he slowly licked up her labia from her clit and gave a flick over her anus.
AJ would moan when she felt her clit being toyed with and her anus getting that big, fat tongue treatment. Applebloom was in heaven. These new feelings she was experiencing made her drunk with pleasure. After AJ had fondled her balls a little, she exploded. Her white, creamy essence flowed out in thick, long spurts with the first three hitting the back of her throat. The next one she pulled a little out for so she could swish it around in her mouth and get a feel for the texture and taste. In order to do this, however, meant that she had to let Applebloom’s hermaphrodite penis out of her mouth which allowed the final strands to splatter across AJ’s face.
Once Big Mac felt that his little sister was fully ready, he mounted her from behind and AJ then felt the full weight of Big Mac on her shoulders. She used the couch for support when she felt her legs buckling from Big Mac’s weight and the expectation for what was to come. Big Mac wanted to make taking his sister’s virginity the easiest he could for her. He lubed himself up with her juices and his precum and penetrated his flared head. It required a little more force with AJ tensing up but he was fully able to get his head inside. Big Mac’s next struggle would be how to deal with the hymen. After some encouraging words to do it fast, he did.
Applebloom watched in awe. Here were her two siblings having sex all because she instigated it by wanting to see her brother’s huge penis. She watched as AJ beckoned her forward when she asked for Big Mac to take his penis out after three to four minutes of sexual fun. Big Mac lied down with his penis speared straight up at full mast. AJ, with her belly facing Big Mac’s belly, got low enough for Applebloom to get her penis in the back door of AJ. AJ’s face was of pure bliss when she went balls deep on top of her brother and then Applebloom got her flared tip into AJ’s anal cavity. This was the kind of bonding the three of them experienced throughout the afternoon. At some point in time they moved upstairs and then the unthinkable happened.
“Applebloom, you can do this. Ah believe in yuh.” AJ encouraged to her sister. Applebloom was trying to get her brother’s massive stallionhood into her tight little vagina.
“Ah can get about seven inches in but dat is all.” Big Mac said.
“Ah can’t believe that ah got duh head in. Ah almost cried wen dat monster got in.” Applebloom added.
The reason why this was so unbelievable was because they still viewed Applebloom as the baby of the family. Children do grow up after all.
“Ah’ma cummin’” shouted Applebloom when she felt the double pleasure from her pussy and AJ sucking on her cock. Her white cream flowed out again and she tightened up her pussy which made Big Mac cum from the tightness of her twat. AJ came a little later after she had been masturbating to her sister’s lewd sounds and the stimulation of her clit.
Granny Smith came home late that night to see her three grandchildren cuddled up on AJ’s bed.
“Now a darn tootin’. If a only they woulda done that years ago.”
The three of them never looked at each other the same again.
