Pleasurable Science done RIGHT
"Don’t worry girls, he should be here any moment now, you’ll just have to wait a little while longer."
Under normal circumstances, Twilight Sparkle would never talk to herself; unless she was scrutinizing over calculations or writing down algorithms to make more sense of the knowledge she gained from reading a particular book start to finish, and she used to never talk to her bust at all, but that was before she became an Alicorn.
There are a few things you should know about this curvy, purple pony princess before we start, one of them already being mentioned previously: Her breasts were massive. The only bra size she was comfortable with was 42F, and even then they spilled out a little bit. Compared to her friends, Fluttershy was the only one who could even come close to comparing to her at a respectable 38E, which was still an entire cup size smaller. Twilight’s flank was equally large and always managed to jiggle with each step, just like her tits if she was not wearing a bra. There was one point when she and her friends were playing truth or dare, and Pinkie had dared Twilight to take a foot long false stallionhood and place it in between her huge plot like you would a hot dog for a bun. Needless to say, she managed to do it with no effort; Rarity was flustered with jealously that day, as she used to be the one pony in the group with the fattest flank. The last thing you should know is that her big breasts came with big responsibilities, as they needed to be milked at least once a day if she didn’t want to leak out in public and drench her shirt in quarts of momma milk.
This leads us to her current situation. Despite being a near genius, knowing everything about everything that knows everything about everything in the known Equestria-verse , Twilight was struggling to complete her own personal project; a proper nursing machine to help 'relieve' her big breasts of the aching that comes from their over-production of motherly cream. She had developed previous milking machines in the past and they were in no way failures by any means. In fact, she ended up selling blueprints of those designs and her proto-type machines on the black market, as she did not want anypony to know she had designed and created such lewd machines. For each contraption, there was one small detail she could not get to her personal satisfactory level. Each milker was a bit too rough on her over-sensitive bosom, making the process a pretty painful practice than a relaxing, pleasurable relief.
This is where "he" would come in. After a bit of brainstorming, she came up with the idea to modify her next milking device to simulate the feeling of actually breast feeding a small foal. From there, Twlight would then continue to update it with more effective and faster milking methods until she found the right spot between super sensational self-indulgence and productive practicality. But for now, the first step was to re-create the sensation of soft sucking, as a small foal would do to a nursing mother. However, Twilight was not at all familiar with this sensation. Twilight had her fair share of fooling around with the known stallions around town, but never had anyone suck on her breasts before, mostly because before her Alicorn Alteration, she was almost flat-chested, and even Rainbow Dash had more of a bust than she did. The guest coming over was somepony who would remedy her inexperience in the world of titty-suckling, although the witty princess may have told a white lie to bring him over. The Stallion thinks he is getting paid for his milking ministrations, which was true, but he won't be milking any cows or goats, like what he was originally told…
A knock on the door brought a light blush to Twilight’s smile. Trying out new things and learning them always excited her, and the fact that what was about to transpire was going to help milk her huge bosom is always a good thing. Having a little innocent fun with an unsuspecting invitee was just a cherry on top of a bucket load of whipped cream.
When Twilight opened the door to her new glass treehouse, she was greeted with the presence of her guest; a cute and shy looking earth pony with an orange mane. His glistening green eyes were in turn treated to an eyeful of her massive cleavage, due to her height being about the same as his, but he was still slightly taller. The shock some males get when they see someone as busty as her is something she's used to by now, but he snapped out of it fairly quick, trying to act like a true gentlecolt, and he starts to look up at Twilight’s smiling face.
"U-um...Princess T-Twlight?"
Big Macintosh stammered, trying so very hard not to look at gifted gentlemare’s huge, heavy breasts.
She giggled in response.
"Yes, that’s me. You should remember what I look like Big Mac, I come around Sweet Apple Acres all the time! Well, actually, I haven’t since my Alicorn Coronation…"
As she brushed back a bit of her purple mane, she extended the other one to the flustered male.
"Pleased to finally have you over! It’s been a loooong day for me so far. How’s your day been?"
"Oh, I’ve been working. Y’know how it is Princess Twilight, buckin’ apples all damn day.”
The Earth pony proceeds to take her hand to gently shake it, only to feel the cold grip of a bronze gauntlet. It gives him a bit of surprise, though the farmer pays no mind to his reaction.
"Please, just call me Twilight, and yeah I know, that’s why you were the first pony I called for this job, as I’m sure a big strong stallion such as yourself will have no issues with handling my requests~”
She walked on ahead, leading her stallion down to her study room, knowing full well the subtle sway of her hips and shifting of her large, round rump catches the attention of that shy little stud, who wouldn’t be able to help but watch that juicy rear as it bounced with each step. Each cheek looks like it would be more than a handful for Big Macintosh, and they were fairly small in comparison to the top heaviness of her tits, with this he thought to himself.
“D-Damn, I’m really gonna have to play it cool, I don’t want Twilight t’ accidentally see my stallionhood bulge in my pants. I can’t imagine how she would react.”
That’s where Big Macintosh was wrong though, as Twilight was in fact hoping that he would get aroused and comply with the task of milking her Big Bouncy Boobs.
"U-um, Twilight, I actually jus’ now noticed somethin’ ..."
The young stud stammered as he looked around the living room beyond the room they just walked past.
"I noticed that...well...I don’t recall you ever owning any farm animals before and..."
"That's right! I don’t have any, which is also my secret to keeping this place neat and tidy."
Twilight responded innocently, knowing where this was going. She took a seat next to a table, where she was studying some rarer books written by Starswirl the Bearded that never made it to shelves before Big Macintosh arrived. She crossed one leg over the other, keeping her expression as innocent and cute as possible, while having her body positioned in such a provocative way to send the right messages that anyone could pick up, just for that extra mile of mental torture to Stallion before her, who was trying his best not to get turned on from seeing Twilight’s voluptuous figure.
"Well, w-where are the cows?"
Mac's eyes went back down to that massive canyon of cleavage Twilight was so generously showing off. He gulped nervously, trying to fight back the urge to bury his face between them for a warm, sexy snuggle.
"Cows?"
She pretended to be confused, even cocking her head slightly for the fun of acting.
"I just told you Mac, I don't own any animals, let alone cows!"
"No...goats?"
"Hmmm..."
She placed a finger on her chin, feigning any actual thinking process. Her arms squishing against the side of her breasts, making more of that jiggly, tit-flesh just push out for the poor, teased stud get flustered even more over.
"I own a total of zero goats, nope; I don’t own a single one!"
"W-wait...then...what am I supposed to be milking?"
"Well~ It's more of a matter of 'Whom', in this context...~"
Twilight hints at Mac this time, slowly trailing a finger up and down her soft, juicy tits...
And when it finally dawned on Big Macintosh, it dawned big time.
"W..Wait Wait Wait Wait Wait…WHAT?!?!”
Not only did Big Macintosh’s face turn into a lighter shade of red, but even his cock started to grow at a much faster rate than it was earlier. Twilight found it adorable, and got up to approach the flustered pony, giving a little sway to her hips as she closed in on him, Mac now backing to the wall and blushing like mad, knowing full well Twilight could see his still developing bulge, looking as if it could rip his pants at any given time.
"Yes, you see Mac, Ever since I was converted into an Alicorn, my figure got a lot more mare-like, and my breasts now have a natural tendency to overproduce milk. I've been making different machines to cope with the process of milking the excess fluids but, I want, no, need to make my next one with a softer touch...like a hungry mouth making sweet love to my girls as it nurses them…and you, Big Macintosh, that’s where YOU…"
She punctuates her word by bumping her huge boobs right in his face, smothering his muzzle easily, making him make a muffled yelp in surprise, his cock growing even hotter and thicker as she trailed her finger down from his muscular chest, to his heated crotch.
"...come in."
Big Macintosh gulped nervously, his heart beating rapidly, and with more blood pumping straight to his almost completely erect stallionhood, which was stealing blood directly from his brain that made him think coherently, the poor, blushing stallion was trying not to feel faint. Here he was with a lovely, buxom mare, and she actually wanted him to have some sexy fun with her. He couldn't be happier.
Twilight gently pulled off her shirt and undid the clasps to her large bra, tossing them both to the side as she wrapped her arms around the horny horse in front of her. There were no more words needed to display what she wanted Big Mac to do, and as her firm nipple was exposed to his muzzle, Mac did not need any more incentive. His lips softly sealed around Twilight’s soft right teat, sucking eagerly as he wrapped his arms around her, rubbing her back, enjoying her soft, warm figure.
Twilight moaned loudly and lustfully as the stud before her sucked super softly on her big bosom, her breasts leaking warm, creamy milk into his mouth, and she gently guided his left hand to her other, unattended titty, letting Big Mac feel how heavy and soft they were. The fat of her tits was just squishing around his fingers and milk was leaking over his hands. Twilight was in absolute bliss as she finally discovered the perfect sensation she was looking for; the loving, erotic feeling of an eager mouth sucking on her painfully hard nipples, draining every single drop of milk out of her huge tits. It felt so amazingly amazing, as she was constantly receiving shivers of pleasure down her spine, making her knees weak, arms heavy, and there just so happened to be vomit on a sweater in the other room. Twilight leaned forward even further, pushing Big Mac against the wall for support as her extremely large, heavy breasts smothering his lean frame and muzzle.
"Nggggghhhh!~ Such a good stud, sucking out all my milk for me~"
Twilight cooed lovingly, softly stroking his orange mane as he nursed from her large tits, the soreness of her right boob slowly faded away as his mouth milked them with extreme skill. The big breasted princess gently pulled back, making the teat that that Big Mac was sucking on eagerly fall from his mouth, and Twilight quickly shoved her other breast in his muzzle, not wanting to leave either of her girls feeling unwanted.
"Cmon Mac, keep sucking nice and fast, just like before~"
Twilight squished him against the wall teasingly, reaching down to gently stroke that big bulge between the Earth Pony’s legs, making him shiver in surprise and bliss while she flat-out gasped. Twilight had been with plenty of Stallions in the past, mostly unicorns and pegasi, but she couldn’t help herself as she rubbed Big Mac’s shaft through his pants and boxers. It was almost as if she would never find an end to it as she kept rubbing down, and down, and down…until finally it stopped just below his knees, and it was hard to make out the difference between his cock and his leg, as they were so equally thick. Twilight could hardly wait to repay him for all the milking he was doing and had already done.
Twilight finally came to, and smiled lovingly at Big Mac, basking in her own sexual sensations. Her hot, wet lips were dripping excessive amounts of mare cum between her legs, and the feeling of relief from the large quantities of milk pooling from her tits into Big Mac’s mouth and onto his coat, and the desire of lust burning inside her as she kept needlessly feeling his thick horse cock throbbing powerfully against her hand. She gently pushed herself back from the horny horse, blushing gently as she gets up from her position on the floor, quickly guiding him to a nearby chair.
"Unfortunately Mac, I’m a little short on bits today, so It looks like I’ll just have to repay you for your milking services…by milking that huge cock of yours~”
She giggled teasingly, slowly unzipping the male's pants, licking her lips as she reached down into his boxers and pulled out Mac’s juicy, thick rod throbbing before her. As expected, Mac’s cock was at the very least an impressive 20 inches and thicker than the likes of a soda can, and the color was a light shade of brown, with the tip being a slightly darker shade. As Twilight held it in her hands it kept throbbing gently, leaking a few tablespoons of precum down his gigantic member and onto her hands, which could barely fit half way around the huge piece of stallion meat.
“Oh my gosh…you are so fucking huge! I can’t believe it; all the rumors were true all this time!”
Twilight stroked Big Macintosh’s stallionhood lightly and smiled before putting her hand on each side of her big tits before she pushed them forward, wrapping them around that pulsing, veiny pillar. As soon as she did this, Big Mac grunted as a rope of precum shot out of his cock, and hit Twilight’s chin dead on before pouring back down onto her huge bust.
"Hehe, You Earth ponies always have such a massive cum reservoir~"
She complimented him and brought her lips down to the tip of his large stallionhood, giving it a sweet, teasing kiss, her full lips covering only half of the cockhead. Big Mac ended up biting his lip from the pleasure and the throbbing of his massive meat was telling Twilight how much he was enjoying this.
"Mmmm, wow, you sure are putting out for me now~"
The purple princess licked her lips, the taste of his precum as sweet and creamy as a fresh glass of apple cider. She kept kissing that yummy cock, with more passion, eventually taking in the entire sensitive tip as she squished her huge, heavy breasts around the base, nearly covering all but the tip she was toying with, making Big Macintosh squirm and moan in bliss as she barely managed to fit the tip of his cock in her mouth and her large tits wrapped around and squeezed the first 15 inches of Mac’s massive member.
The sweet taste of apples made Twilight suck and slurp his dicktip eagerly as she continued her own little milking on the pony, savoring the abnormal amount of precum Mac’s wonderful cock produced, not letting a single drop go to waste. It wasn’t long before she discovered that the Poor Red Earth Pony was not going to last much long under all that buxom, oral pleasure, so she pulled back with a wet, loud pop, sending a nearly orgasmic shiver down his spine as Twilight continued to stroke Big Mac’s huge stallionhood, which was now throbbing extremely hard as copious amount of Mac’s precum was freely pouring out of the tip of his cock, ready to unload any second now…
“Cmon Big Mac, let it all out~ Don’t you wanna coat this princess and her heavy breasts with a big load of your cum?~ Just explode already and let your huge cock coat me in white!~”
As Twilight said that, she had pulled the trigger tenfold. Big Mac leaned his head back and groaned loudly and the first spurt of cum rocketed out of his throbbing stallioncock, immediately splashing upon the top of Twilight’s breasts and oozing down covering the top half of them before the second salvo came, which was twice as big as the last, managing to soak her mane with some landing on the floor a good 3 feet behind her. The third, forth, and fifth spurts were all equal in size and force, splashing against her face, horn, arms, breasts, and stomach, and Big Macintosh wasn’t even half way done with his massive orgasm.
“Oh my Luna…I better do something before he turns my coat entirely into semen.”
Twilight thought to herself before shoving her muzzle back onto his still spasming stallionhood, where she was able to catch the sixth and seven spurt, which made her cheeks bulge extremely wide before she swallowed it all and was rewarded with another 5 ropes of sticky stallion seed, which she managed to swallow with ease due to the volume and felocity toning down to that of what Mac used to produce when he had just passed through puberty. The nearly drained Stallion was panting and moaning from the amazing sensation of cumming as hard as he did.
When Big Macintosh came to, he was greeted with a sight like no other. His pony splooge was covering the entirety of Twilight’s face, horn, mane, bust, and stomach, while only a cup managed to get on her arms and thighs. After a half a minute of Big Mac watching Twilight rub his cum into her fur, mostly on her breasts, she gave a short sigh as he horn lit up, and all the cum in the room disappeared, most likely teleported to the Equestrian Sperm Bank. Twilight was never very original in thinking of a different place to teleport it to, trust me, I’ve watched too many of her “sexy sessions” to know this.
"Holy Celestia...Twilight…y-you're such a goddess!"
He blushed softly, reaching up and groping the Princess' massive bust. If Big Macintosh was a cartoon, he would probably have hearts in his eyes right now due to the fondness he was feeling towards Twilight. Unbeknownst to Mac, he was a Cartoon, but since cartoons do not realize they are cartoons, he probably did have heart shaped glare in his eyes, and just was not aware since…well…I’ve said too much nonsensical noobery already so I’ll just stop here.
"I was only being fair; a milking for a milking, but great celestia you sure came a lot, when was the last time you had some fun with another mare?"
“I don’t k-know…M-Maybe a month now? Carrot Top hasn’t been visiting me lately…”
“Well…if your output is any indication, she’s probably still getting your load out of her fur.”
“Hehehe, yeah perhaps…”
Twilight giggled before nuzzling the equine's muzzle as she stood over his lap, slipping her lower garments off, revealing her soaked marehood.
"I think it’s time we end our mutual milking with a bang!~"
She then lowered herself down onto Big Mac’s throbbing horsecock, moaning as she felt the thick meat pierce her nether lips, hugging Big Mac tightly as she slowly ascended down the almost two feet long stallionhood, burying his face between her big bosom, and the pleasure made him retort with a firm sucking on her breasts, squeezing them both together so that he could fit both of her nipples into his mouth, causing her pleasure to double from the milking she received earlier. This type of sucking sensation was most certainly going to be a feature on her upcoming milking machine.
Her pussy walls clamped down and squeezed lovingly around the entirety of Big Mac's member, keeping him snug and warm inside her as she slowly began to ride him up and down, biting her lip as his cock stretches her marehood out more than she thought physically possible while Mac’s cock throbbed against her most intense areas, the pleasure causing more milk to pour from her large bust and directly into Mac's eager, sucking muzzle. As Twilight bounced lustfully on his lap, the Stallion softly groped her large, juicy flank, massaging it and lifting it up and down in time with her riding, feeling in heaven as her marehood milked his massive dick with such tight, loving friction.
Twilight began to pick up the pace, riding Big Mac harder and harder after only few minutes of rough, wild grinding, feeling that climax building up. Her heavy, powerful pounding on his lap causing the chair to creak and moan from both their weight, even making Big Macintosh grunt as he was repeatedly squished against by so much sexy softness; Twilight massive chest, her soft plot, her marehood wrapped tightly around his cock, which was starting to pulse and throb even harder as he sucked harder on her tits, uncontrollably thrusting upward as his balls churned and boiled with need the need to cum inside the purple goddess.
"Give it to me, little pony~ Hurry up, fill me up with litres of your delicious cum~"
Twilight urged him, softly kissing and licking his tongue. Her tight pussy, her huge breasts, it was all too much for the stud to take, and he soon exploded inside her with the first huge volley of sticky, hot cum, pumping deep inside her womb. Twilight moaned extremely as what felt like a gallon of jizz was pumped into her with just the first spurt and already drops of cum were leaking out from her marehood. The next 3 ropes filled her up even further and cum was now gushing down onto the chair and on the floor. Twilight could not even comprehend what was going on with the massive load being pumped into her, all she could do was stare up into the ceiling and moan louder than she ever did before in her entire life.
"Ooooohhhhh!~ T-that’s it!!~ I'm g-going to milk EVERY d-drop out of you…just like y-you did for me~"
The buxom princess cooed, getting very close as she just kept bouncing on his lap to drain those huge balls, making sure he gives Twilight all he can give, all right before the pleasure got her to climax in her own wet, delicious way. Pools of her juices gushed out onto Big Mac’s lap and the chair below them as she started hugging him, giving him a boob-smothering embrace as she cried out in sweet bliss.
The two enjoyed a rather long, heavenly ascension to that orgasmic paradise. Big Mac had placed about a litre of cum inside Twilight, with the other litre leaking out all over the place below them, and Twilight squirted a good 5 times before her orgasm finally died down. They held each other close until the after-orgasm sensation left them and the two kept their embrace for a while longer, giving soft, gentle strokes along their manes and fur, Big Mac was panting like he would after an entire days’ worth of apple bucking as he nestled in between the princess’ large, soft breasts.
As for Twilight herself, while she was very much exhausted from the deeds she and Big Mac performed, her mind was working like clockwork, already keeping track of every wonderful sensation she experienced from this little experiment. At this point in time, she is now very confident that her next breast milking device will be her best, being able to milk her just as good, if not better than what Big Mac here did. Even with that said, she was still thinking about contacting him again, just in case she wanted to have some more fun with him.
You know, for science and stuff obviously.

I hope you all regret your decision to read this ugly whore of a story.
Oh, and apologies for the somewhat misleading cover, couldn't really find anything that would fit this type of story.
