Rainbow Dash lost count how many times she had uttered the phrase “the best sex ever” during the last few days. She didn’t know what had brought the sudden spike to their already incredible lovemaking and being rutted silly by his seven inches in their bedroom wasn’t much help to gather her thoughts.

Hard Knock had become relentless in his efforts, reducing his marefriend to cries of pleasure and would continue until her orgasms reached the double-digit numbers. Unable to move from muscle spasms, she had admitted defeat two mind-numbing rounds ago and didn’t protest when he raised her sore flank for another.

Rainbow was bended over, folded and entered to mold around him like a well-fitting glove until her entrance had shaped itself to the form of Hard Knock’s throbbing length. Her womb would accept no substitutes anymore, shown by how unsatisfying borrowed toys from Berry had been during the few times she tried. Similar to a lock, only his matching key could get Rainbow to the orgasmic heights she was getting used to experience.

And he gave it to her whenever she wanted.

The calm brewer had transformed into a force of nature. The training at the gym was harder, the workhours in the cellar were longer and she noticed him sitting a lot less in his wheelchair. She welcomed his new attitude, but all the unleashed energy seemed to go mostly into banging the blue off her coat every single night.

The grip around her hips changed, his hooves taking a tighter hold to pull Rainbow towards him. He sat down and thus putting her into his lap to spear the last inch of stallionhood into velvety wet depths under the scratchy moan of his marefriend. Tightly connected, his grip changed again to hook his front legs under her armpits and the plum hooves touched behind Rainbow’s neck.

Hard Knock had put the smaller mare into a full-nelson hold.

“Oh, Celestia have mercy…” she thought with a gulp, salivating in anticipation of things to come.

In their time as a couple, her coltfriend had yet to show any repeats from his endless bag of tricks and he didn’t disappoint this time either, taking full advantage of the hold to move rapidly without having to adjust after each plunge. The rhythm changed from the earlier hard single thrusts to literal jackhammer pounding into her core that made their whole bodies vibrate.

“Th.. Th.. This… mi… might… b… eee… my ne… new favourite!”

The right stimulus followed with a bite on the scruff of her neck. Warm shivers ran all over Rainbow and distracted her from the final part until it was too late to stop him. It wasn’t as if she would have if she’d noticed anyway when his hindlegs joined in constraining her own, completely making her unable to move a muscle while his hips picked up the pace even more.

They were both now lying on their backs, Hard Knock on the bed and Rainbow snuggly on top of him when his loud groan announced the last spurt for the night. Rainbow screamed in ecstasy over the deafening wet slapping sounds of flesh against flesh, mouth drooling a river as the dominating male beneath her went berserk to breed his mare to satisfaction.

A task he accomplished for the umpteenth time tonight with a fountainous release around his cock, drenching his lap in her love fluids.

“Hah… uh… ugh…” Out of breath and spent, she felt the hold loosen and her body being moved. Hard Knock rolled on his side and Rainbow off him, spooning the mare and re-tangling their hindlegs loosely together.

After mind-blowing sex always came cuddling and light fondling to complete their lovemaking until both dozed off together.

A simple, straightforward and heavenly routine.

“Let me be the big spoon tonight.” Every word from her lips were a chore to get through. Only the training regiment with the Wonderbolts could compare to the level of exhaustion she felt after a good rutting from her coltfriend and the soft caresses of her ears afterwards were just too unfair to go up against.

Tonight, Rainbow prepared to fight the impending afterglow coma of their thorough sexcapades. It was still difficult to stay awake, the gooey warmth of Hard Knock's essence inside and his sweaty body against her lulling the mare into drowsiness. The intent was to ease her overstimulated body into the best sleep possible, so just pretending to sleep without nodding off was a herculean task for the exhausted mare.

She achieved her goal by painfully biting the insides of her cheek for several minutes until Hard Knock succumbed to the realm of dreams and Rainbow sprung into action as soon as his breathing calmed down. Her coltfriend was hiding something, and he was too on guard to let anything slip while he was awake. The defenses came down during his slumber and she planned on getting the truth directly from his body.

“Those two idiots at the gym must be wrong... At worst he has a few strained muscles...”

The first thing that proved her wrong was the rigid feel against her hooves as she traced his back. Even in deep slumber, Hard Knock was tense as a board, emanating slight shakes from his muscles at her touch.

She shuddered from the callous texture of his hooves. Every part of earthponies were always so rough and solid, brimming with the strength of their powerful muscles. This close to his physique, Rainbow remembered an old rhyme about earthponies that an old instructor had taught them at flight school.

“Pity the rock lying on the ground, the joys of the sky it never found.
Dirt is its home and where it may stay, the majestic blue a world away.
While mud is its blanket on starry nights, we enjoy the celestial delights.
Once broken the rock may never be whole, a feather may drift but reaches the goal.
I pity the rock for it will never be, anything more than a tiny speck to me.”

The proud recital at home had been one of the few occasions when her parents had not given their daughter a trophy. She remembered a lot of scolding, an evening without supper and a furious crowd of parents in front of the principal’s office on the next day.

Low key racism aside, pitying earth ponies was stupid because they were awesome in their own rights! Rainbow always bragged about her toughness, but she didn’t know if she could have shrugged off an accident like her coltfriend. As his marefriend, she had insights into his health record and calculated with Twilight that the same injury would have killed both of them ten times over.

Hard Knock was one tough son of a mule.

“He’s on edge... nothing too worrying...” Rainbow thought, failing to convince herself and pressing a spot between his shoulder blades too hard on accident.

The small whimper from his sleeping form shook Rainbow to the core. She never imagined such a sound from her strong coltfriend. His whole body trembled, and he gritted his teeth to the point of making grinding noises. The little poke set free a cascade of suppressed pain that wrought havoc on him as he writhed in agony, not enough to break Hard Knock out of his deep slumber that reminded Rainbow increasingly of unconsciousness.

She fought against a building lump in her throat, staring at the proof of her failure as the breakdown of his tough shell broke her own. Tears ran quietly down her face as she nuzzled his cheek and swore to make things right.

Confronting him would hurt his pride, she knew from her own experience.

Instead, Rainbow settled for being extra thoughtful, extra loving and extra awesome to repay his efforts tenfold, starting with something special right now.

Her personal drawer in his nightstand had one object that stood out from the various energy bars and clutter of other convenience items. A rolled up scroll, sealed with a faintly glowing wax stamp with regards from Twilight. The egghead had fully delved into this new field of magic for couples and made a portable version of a very special spell. A stomp with her hoof cracked the wax seal and made her body glow to show the established connection between spell and user. She unfurled the paper and instantly felt tingles wash over her in waves and slight burning at her crotch.

The first visible sign was the hardening of Rainbow‘s nipples in a well-tempered room. She moaned from the building pressure as small blue mounds grew underneath the pink nubs. Growing milk teats excited her every time and Rainbow felt the temptation to indulge in the flood of hormones coursing through her body. She had to act quickly, already feeling small droplets form at the tips.

Gently, she laid on the side and positioned herself to give him comfortable access to the rosy knobs. A smile graced her lips as he reacted instantly to their presence and puckered his lips on instinct. It needed no convincing to make him suckle at the first possibility, his hesitation brushed away by the deep slumber.

Relief came with the first stream of thick cream leaving her body although Rainbow didn’t get much arousal from the licks and suckles of her coltfriend. The foundation was there, slight tingles and all, only muted by the tenderness and delicate nature of his tongue movement. The warm glow in her chest came from nourishing somepony she loved and providing a piece of herself as a tangible source of comfort.

Her hoof stroked his mane while he subconsciously fed on her, the muted suckling and smacking of lips as only background sound in the quiet room. The sleepyhead was hungry, resting his head on her left teat while he suckled on the right and getting the milky residue all over his cheek.

“You are a messy eater...” She breathed faintly into his ear, guiding Hard Knock carefully to change nipples so she could clean his face with a few licks.

Hard Knock smiled in his sleep from the wet warmth, letting more milk drip out of the corner of his mouth she cleaned up. Soon, the intent changed from cleaning her stallion to shower him with affection which influenced a lower part of Hard Knock’s body.

The limp spire slowly wormed its way out of the protective sheath, still red and tender from their aggressive lovemaking. Another grab into the drawer produced a tube of ointment to oil up the weary spire. Despite the countless rounds of hot, steamy sex, the shaft soon stood hard and rigid again with visible throbbing. After taking a mental inventory, Rainbow Dash realized he had not climaxed at the end.

“I love you, you stupid selfless numbskull. I love you, I love you...” Every exclamation stressed by a kiss on his tip and a pump along the shaft, but her eyes fixated on Hard Knock’s face. “I will let nothing get in between us. Not even our thick heads!”

She vowed this with all of her might through his weak ejaculation, softly squishing and pulling on his sack to help along with the release. Her first instinct was to lick off the thick white cream from his dripping shaft, but she waited until it slathered the whole length with strong-smelling liquid. The odor transferred to herself when she nuzzled the sticky appendage like a cat would her owner and Rainbow marked herself with his scent, past the coat and the layer of her skin.

Tomorrow, they both would get knowing looks from ponies and she didn’t care in the slightest.

Mushy didn’t bother her anymore. Looking weak didn’t bother her anymore. As long as she got him, everything else was less important. A line of thinking which was dangerous, he had said so many times, but Rainbow couldn’t fight her feelings and the hypocrite suffered as much as her by trying to keep her happy.

Two numbskulls, well underway to destroy their health and reputation respectively with good intentions.

Rainbow had expected that the first time they used the magic scroll would be a happier moment, a more lewd night with lots of amazing sex and indulging in perverted fantasies. The thought of his cock being sandwiched between her swollen teats had excited the mare since she filled up that first mug of milk as a present for his hospital release.

But ultimately, the unveiling of her new assets boiled down to giving her coltfriend a midnight snack and a hoofjob.

And the smile on his face made her satisfied with it.

For now.

MUST... FIGHT... WRITERS... BLOCK!!!

I'm doing everything I can to get out of my writing anxiety. Part of it is releasing stuff I'm not completely satisfied with, but I feel like actually getting things out is more important.

Hope you found enjoyment in this chapter.
