`A pebble hitting Apple Bloom’s window woke her up. Of course she had a stiffy, but ignoring it, she waddled over to the window, opening it and looking outside. “Psst!” came a filly’s voice, sounded familiar, but Apple Bloom couldn’t really place it. “Who goes there?” Apple Bloom whispered loudly. “It’s me, Liza!” came Liza’s voice. Oh, uh oh. This might take some diplomacy. “Hold on, ah’m comin’ down,” Apple Bloom called down quietly. Opening her door, she carefully crept downstairs. Out in the pre-dawn air, Liza was standing there all fidgety. “C’mon, follow me,” Apple Bloom said, leading the filly over toward where their clubhouse was. With the light on, in the relative warmth of the sheltered walls, Apple Bloom could see the filly’s soft blue fur, and her purple mane that parted softly around her fluted horn. “Alright,” Apple Bloom said, “Ah’m guessin’ you’re here for more help with your estrus.” “N—wha?” Liza said, her purple eyes widening in surprise, “No, it’s not that!” she said, blushing and adding, “I mean, yes it is that, but that’s not why I wanted to talk to you. I’m sorry it’s such a bad time. I had to sneak away, because my grandma thinks it isn’t safe to go out this season!” “Well, why’re you comin’ out here, then?” Apple Bloom said a little grumpily. “I–I just wanted to apologize,” Liza said softly. “I thought you’d still be mad at me!” “What fer?” Apple Bloom asked, but she realized then and said, “Oh, you mean that whole thing with Diamond Tiara?” Liza nodded, ashamed. “That ain’t no thing,” Apple Bloom said casually, “We got past that with a little shindig that showed a buncha fillies that ah wasn’t gonna make them sick at all.” “O-oh, really?” Liza asked, surprised. “But I am really sorry. They said even your friends were afraid of you!” “Oh, Sweetie was afraid of herself, really,” Apple Bloom said. “Her sister has a hard time with heat, and she was scared she would be the same way. Wasn’t about me in particular.” “Is she?” Liza asked curiously. Apple Bloom shook her head. “Nope, we proved that pretty clear right off the bat. She’s about the sweetest filly you could ever put your boy thing into.” “O-oh...” Liza replied with a blush, thinking about her distinct lack of any boy thing whatsoever. “I guess I s-should have just talked to you at school then. Sorry I woke you up this early for nothing.” “Say, if’n you really wanna make it up to me, why don’t you raise your tail for me?” Apple Bloom suggested, “We both have fun then, and ah’ll even be glad you woke me up this early.” “But that’s for helping me, not you!” Liza said with a frown. “I wouldn’t say no, I mean, but why would it make you glad?” “Liza, right?” Apple Bloom asked, receiving a nod in response. “Filly, you remember where ah went last time, there in between ya hips?” “Nnh... yes,” Liza admitted, squirming her hind legs together. “That place you got in there feels better than anything in the whole world, for a colt,” Apple Bloom told her, surprisingly enough. “Ah wasn’t just curin’ your estrus. I get to orgasm too, when ah do that! Just the thought of it is... well,” he lifted a leg, and oh jiminy his penis was out, and it was huge! “So stick your butt in mah face,” Apple Bloom said eagerly, “An ah’ll fill y’up with boy stuff, and it’ll feel awesome for me, and for you. Ah can only do the half stop though, on account of ah gotta save some for mah friends later this morning.” “The half-stop?” Liza asked, confused. “It means ah won’t be putting as much boy stuff in you,” Apple Bloom said, “Works just as good, and there’s less wasted. Like, just enough t’ stay in you, instead of gettin’ all over your legs and the floor.” “Oh, that’s... kind of nice, actually?” Liza said, just wanting to feel boy stuff at this point. “So I won’t have to clean up?” “Oh a lil’, mostly it’s just to stop wastin’ mah boy stuff,” Apple Bloom said. “Here, c’mon an’ let me show you.” Liza presented and her nethers throbbed needily. Estrus was just awful! But there was a colt here, and amazingly, he was going to do that thing again, where he filled her, and it was a reward for him, too! She wanted to feel that again so bad. When Apple Bloom’s tongue hit her, Liza thought she was going to explode, a hungry need rising in her like a wildfire. He cleaned the itchy, sticky heat right off her, and pressed his tongue against her, and slid it inside~ “Please...” Liza quivered, “C-climb on me again.” “You got it,” Apple Bloom agreed heartily. Liza looked back while he climbed upon her soft blue rump, and her tail curled around behind his torso. At the slap of his penis against her vulva, Liza looked forward again, lost in the achy, needy slidey feelings that made her legs lock up, and her tail arch back away from her treasure. It was so fascinating when Apple Bloom’s penis entered her. Liza appeared to have some kind of a... slidey place in there, like a penis shaped pocket made out of her own wet, slippery flesh. It stretched when he thrust into her, and spread again and again, making Liza breathless with need. She couldn’t believe there was a penis in there, in her! Apple Bloom was so stiff and firm, every time she winked he fought with her to keep thrusting. It didn’t even hurt this time, not that Liza cared if it hurt the last time. This time though, it was just pleasure, growing and growing, until her whole body felt like it was sparkling and beautiful. Then, it all just crashed on her like an ocean wave, as her inner place sang like a beautiful choir for a moment, then convulsed helplessly around that colt’s thrusting penis. Liza’s eyes slid half closed, a slack expression on her face as her every thought turned to that penis, to that boy, and the strange, rhythmic contractions around him that just kept happening and happening. She couldn’t tell when they stopped, because he was still thrusting, and all Liza could do was stand there in a blissful daze, feeling her inside place slid into again and again, by a penis. He abruptly stopped thrusting then, grunting tensely and driving deep inside her. In that strange, fleshy space, Liza felt his penis flare and she didn’t know why it was doing that, only that it felt amazing to be filled by such a thing, for it to press against every inch of her in there. She tried to squeeze it consciously, once again feeling it start jerking inside her. That was what happened right before—! Hot jets of semen spurted from the tip of his penis, tingling as they touched her, making Liza hunch forward and bear against him, panting at the hot, slimy explosions every kick of that boy’s penis delivered into her. She looked back, pushing her round pelvis against his indulgently, huffing at the feel of a boy’s jerking shaft making her so slimy in there. He pulled out as he did it, squirting into her passage all the way, until he gave a strangled, “Rrrah!” and slipped away from her entrance. A hot spurt hit her pelvis, sliming along her nipples, then... nothing. “Unh...” Apple Bloom said restlessly, pushing off of Liza’s rump, and standing splay legged around his swinging penis. “Pulled out a lil too soon,” he said, “Got a little on your uh... place.” “It’s so okay,” Liza said in relief. “I think your stuff makes me feel good on the outside, too!” She reached back a hoof and rubbed it into her vulva, saying, “Boy stuff is amazing~” “Y-yeah, uh, better stop... that or ah’ll have to put the rest into you,” Apple Bloom said, unable to look away from the pony rubbing seed into her soft, blue vulva. “Ah need to save it for Sweetie Belle, later.” “O-oh, sorry,” Liza blushed, pulling away her hoof and letting her tail drop down. It was so much easier to do so, now that she had Apple Bloom’s goo in her. With that slimy boy goo wholly contained in her small round hips, she could feel her estrus ebbing away already. “And I’m really... glad you’re not mad at me,” she said. “Do you think my estrus is going to come back again?” “If’n it does, go talk to Sweetie Belle,” Apple Bloom said smartly. “She’s helping fillies out with that stuff, an’ maybe she cain even find you a colt to fill you up regularly, even without needing an estrus cure.” “That’d be so awesome,” Liza said, wide eyed. “A colt of my own? I–I mean it doesn’t have to be you, but—” “Remember there ain’t as many colts as fillies,” Apple Bloom cautioned her, “But a colt cain take care of at least 4 fillies, so if you don’t mind sharin’ you’ll be as happy as a filly cain be.” “Oh... oh, no I don’t mind. Thank you,” Liza said gratefully. “I can’t believe that you’re so nice! I–I can actually... actually sleep again! Oh this is so wonderful...” She continued her heartfelt praises, bidding Apple Bloom good day, and trotting off to sneak back into bed, her fillyhood changed by the boy stuff she secretly held within it. As for Apple Bloom, “Land sakes,” Apple Bloom grumbled, “That half stop thing is terrible! Ah cain’t even stop thinking about it! I wanna take a filly’s butt an’ just jam it in and empty out into her. I–I cain see why I did it before, and didn’t even ask her name. It’s just... so awesome to do, and achy now that ah got stuff in me that needs ta get out. “Ah am definitely gonna get two fillies lined up at the same time, if’n ah try to do this half-stop thing again,” Apple Bloom concluded. In the farm house, she stopped short at a figure standing there in the darkness. “Apple Bloom!” her sister Applejack whispered admonishingly, “What were you doin’ awake at this hour? And with a filly?” “W–well it was... she was just...” Apple Bloom hung her head. “Ah caint lie to you, sis, but what we were doin’ ain’t wrong!” “W-wait you really were...” Applejack said in shock. “Boy stuff,” Apple Bloom told her. “Ah know exactly what it does, an’ ah was using it to put an end to Liza’s estrus. A-ah know how to use a boy thing, and that fillies have a special place to put it.” Applejack wanted that colt so bad, it hurt. Her nethers were outright drooling at what he was talking about. “S-so ah’m not sorry,” he said, looking up at her defiantly, “An’ ah think adult ponies are crazy for not lettin’ us do this. So... punish me if’n you want, but ah won’t stop.” “Punish you?” Applejack declared in surprise, “You’re punishin’ yourself enough doin’ that! Don’t you know what’ll happen?” “Yes, ah know, and if ponies would just let it happen, it’d be a lot easier for all of us,” Apple Bloom replied. Her anger fell to concern as she urged her sister, “Applejack, you have estrus, and you got it bad! A-ah know I’m just a colt, but ah cain help a grown mare too. Please, let me help you!” “You caint... it’s not a good idea...” Applejack said weakly, her passage crying out to be filled with penis, and to make her belly big with foals. “Ah mean maybe it’s not such a bad idea,” she admitted, “Y-you won’t hurt nopony if you just put it in.” “Oh good,” Apple Bloom said, relieved, “Ah’ve been real worried about you. C-cain we do it now?” “Now?” Applejack squeaked. “Yeah, ah uh...” Apple Bloom blushed saying, “Ah did it to Liza just now, an’ ah only half-stopped. So if’n ah finish in you, it’ll be nice and neat, a-and ah really need it. Ah caint get un...boystuffy until ah finish.” “Y-you shouldn’t...” Applejack should warn Apple Bloom, but then Apple Bloom would never give Applejack what she desperately wanted! “It’s... fine what you did to Liza,” she outright lied, “Just... just please do it to m-me, if’n... if’n ah...” she couldn’t help it, she presented. For her kid sister turned brother, Applejack presented, and winked. “It’s okay sis,” Apple Bloom said kindly, nuzzling the side of her rump. “Ah won’t let you down.” Then he buried his muzzle in Applejack’s pussy. When Applejack climaxed, she was as worked up as the colt who was going to fuck her. This was such a great idea. Apple Bloom loved her so much, and Applejack felt silly for blowing her off like this. Sure, Applejack might get... foals... but just the thought of that was almost enough to make her cream. He could fill her up with his stuff, and nopony would know Applejack was with foal. She could lie about... about some pegasus flying down and doing her. She could bear Apple Bloom’s child, and it’d be their little secret! “S-stool,” Applejack said drunkenly, pulling one of the kitchen stools over for her sister to stand on. “Y’could just lie down,” Apple Bloom pointed out, but Applejack shook her head, whispering, “No, you gotta do me standin’ ah need it.” She stood in front of the stool and raised her tail, and Applejack had to whimper with how good it felt to do so. How right. What would she name the foal? Apple Promise? Apple Penis? Apple Sheneededcockrightnow? Apple Bloom climbed up on the stool, hugging his sister’s wide hips, and then Applejack felt it. She had to bite her arm to keep from squealing as Apple Bloom’s shaft finally graced Applejack’s inners. Her younger sister gone brother was eager to thrust, needy even, and his dick wasn’t as big as Caramel’s, but it was his, and Applejack loved to pieces how Apple Bloom could fit entirely inside her, and grind his pelvis up against Applejack’s sensitive clit. The only sound was quiet squelching noises, and intense breathing, breathing to the rhythm of their thrusting. Applejack couldn’t believe it. If this worked. If he finished in her. Terrified that her older brother would find them, before it was too late, she didn’t make a sound. Apple Bloom was just fucking her half in the kitchen, and if she could just keep this up, he’d—! Apple Bloom flared in her. Applejack was beside herself with anxious joy. She tried to tell herself that it was a bad idea, that family shouldn’t intermingle, but all she felt were her wide, powerful hips filled up with her little brother’s shaft, bucking back against him even as he bucked towards her. Oh, when would he climax? When would it be too late to turn back? He was... he was... He lost the stool when he climaxed, kicking it aside with a clatter. Applejack froze at the noise, sounding loud in the quiet of their mating, but Apple Bloom hung onto her rear, pulling himself to hump against her for those all important final strokes. He pushed deep and didn’t hump any longer, and... his shaft started jerking oddly in Applejack’s quim. Was this it? Was this what it felt like when a stallion was about to— Hot seed outright struck Applejack’s inner passage. She gasped at the feel, the sliminess, and the tingling. His penis kicked and splurted in her, like a bucking bronco, smearing it all around and—and filling her! His seed was spreading to crevices in her she didn’t even know she has! She never knew it’d feel like this! It was making her climax just from the feel of his seed, and the knowledge of what it was. With a quiet moan, Applejack started convulsing around his shaft. He only ground against her more earnestly. Oh, he was squirting in her! His seed, she could feel his seed! She was a—a momma! “Oh momma ah’m so sorry,” she whispered too quietly to hear, but the only answer was a hearty spurt within her. Applejack couldn’t feel sorry. All she could feel was a soothing warmth within her hips, and a colt hanging onto them, delivering his seed into her like a pony possessed. She lifted her head when the spurts stilled, looking back at him. Apple Bloom gave her a weary acknowledgement with his fiery orange eyes, then slid off her butt, and out of her butt, thumping to the floor. Leaving the relaxed colt where he lay, Applejack looked at her own butt, at the marehood that butt contained. What would it be like giving birth through that thing? Likely not very pleasant. Applejack could hardly care at all though, because his seed was doing an amazing magic inside her. The burning in her cunt calmed and soothed, and it spread through her whole body. Her shoulders relaxed, her muscles untensed, even her hair felt... softer somehow, less irritating as it lay along her thick neck. Apple Bloom had stood now, and walked up to nuzzle her in the side. “Thanks so much, sis,” he said lovingly, “Ah wanted to help you so bad... how d’you feel?” “Amazing,” Applejack murmured, laying her head over his, every touch of his body against hers a sensual pleasure. “Didn’t know it’d feel so good.” “Y’never did this with a stallion, huh?” Apple Bloom asked her contented sister. “Not once,” Applejack agreed, “Few close calls, but when you finished, that was amazin’. Ah’m sorry, but... glad you did it.” She touched her soft nethers with a forehoof, saying, “Got lil’ Apple Bloom up inside mah hips, even now...” “Why didn’t ya do this before?” Apple Bloom asked her in a worried tone. “Did you not know about it?” “Nope,” came a very disapproving male voice. Big Macintosh charged down the stairs at them. Thinking fast, Apple Bloom reared up on her sister, whining, “C’mon, sis. Why won’t you let me do the boy thing with you?” Big Macintosh pulled Apple Bloom away from her sister, and Apple Bloom continued to say, “Ah’m sure you’d like it, if’n you just gave me one little chance!” Eyes widening at her sister, Applejack said, “O-oh yeah! That’d be real inappropriate, Apple Bloom! Ah caint believe you would even suggest such a thing!” “Ah guess ah still have lots to learn about bein’ a colt!” Apple Bloom called out to her sister, continuing to get dragged away. “But you gotta tell me all about why it’s a bad thing to do this, one of these days!” “Apple Bloom,” her brother said, once he got her alone. He got right up to her face and said, “Applejack ain’t gonna be able to make the right decision. She’s puttin’ on a brave face for me, but she ain’t got the willpower to refuse you. Fillies, they ain’t... got no choice about estrus. So it’s up to us stallions to make sure they get a choice. You understand?” Apple Bloom nodded silently. “She’s gonna ‘do the boy thing’” he said, “With the stallion she marries, just like our ma and pa did, just like granny and our grandpa did. She’ll be happier for it, and there won’t be no trouble no more. She’s just gotta wait until she meets the right stallion.” “She’ll be happier right now,” Apple Bloom grumbled under her breath. “What’s that?” Big Macintosh asked warningly. “Ah hear you, Big Mac,” Apple Bloom said resignedly. “Ah won’t do anything funny with Applejack until she finds the right stallion. Sorry you care so much about that sorta thing.” “Ah’m just lookin’ out for her, and for you,” he said. “We gotta stick with what’s proper.” Apple Bloom just sighed, and looked at him with what honestly might have been pity. Still, he was her brother, and he was trying to do the right thing. Maybe he was right? She wouldn’t get any information out of him, so she asked her sister instead. Applejack, who was humming a tune as she bucked apples, looking pleased as punch, even serene as she did so. It was probably the most relaxed Apple Bloom had seen her during applebuck season, and now Apple Bloom knew why. Her estrus just needed a colt’s boy stuff, and now that those thick orange hips were full of Apple Bloom’s, Applejack could finally get a moment’s peace. “Howdy sis!” Apple Bloom said, trotting up to her sister. “How’s the apple buckin’ going?” “Howdy there, Apple Bloom!” Applejack said with a genuine smile. “It’s goin’ great! Ah think I might get the west orchard done today, since... you know.” “About that...” Apple Bloom said nervously, “Big Macintosh has been kinda sayin’ that it’s bad to do it if’n you’re not married first.” “Well, that old lug just don’t know what it’s like,” Applejack said, kicking the next tree a little harder. “Marriage is a big committment, and ah just couldn’t wait. Or rather... we just couldn’t wait.” Apple Bloom chuckled at that, going, “Yeah, ah guess we kinda couldn’t.” “He’ll find out eventually,” Applejack said, looking distantly in the direction of the farm house, “But we’ll just have to cross that bridge when we come to it.” “Wish he wasn’t bein’ so unreasonable about all this,” Apple Bloom sighed, shaking her head. “Ah feel like ah’m missin’ something about it.” “Missin’ something?” her sister asked cautiously, bucking the apples out of another tree. “It ain’t gonna hurt you none, is it?” Apple Bloom asked Applejack worriedly, “That filly place is made to hold boy stuff, right? Ah’m just worried that there might be consequences to puttin’ it in you like that.” “You don’t know?” Applejack squeaked. “What?” Apple Bloom replied confusedly, cocking an ear. “A-ah said no, it’s uh... ain’t no consequences,” Applejack said with an unsteady grin, “Completely harmless what we do done did. You didn’t hurt me none at all.” “Oh good,” Apple Bloom said, relieved. “Just the other foals at school were sayin’ it could make you sick.” “Well, don’t listen to them, because ah’m fine, and everything is just fine and dandy,” Applejack said desperately, “But uh, just promise me you won’t do what we did with any other fillies.” “What?” Apple Bloom said, taking a step back in surprise, “Why?” “Just promise me!” Applejack said with a pleading grimace, “It’s perfectly fine what we did, and ah’ll be okay no matter what, but just promise me you won’t do it to any other fillies!” “Okay, okay!” Apple Bloom said in frustrated alarm, rump hitting a tree from her sister’s earnest advance. “Ah won’t... do that no more with other fillies,” she grumbled lowly. “What was that?” Applejack asked suspiciously. “Ah said ah won’t do that with any other fillies,” Apple Bloom stated. “There, you happy?” Applejack patted her on the head, smiling and saying, “Pleased as punch. We can um... we cain do it, just you an’ me, as much as you like though.”
