OK, Rumble, showtime! Get over there and show these mares what you can do!

Rumble looked at Fleetfoot, lying on her back on the bench in front of him, legs spread, tail aside, her estrus-swollen, deep-purple vulva exposed for his viewing. Her lower lips were slightly parted, showing a sliver of her deep-pink insides. The sight only made him that much more aroused as he remembered making her squirt for him just minutes ago, her fertile flavor still on his lips and tongue. "Come mount me, my handsome stallion," Fleet said, and Rumble jumped at the opportunity – rather literally.

Rumble, unable to restrain his desires any longer, cock hard as a rock beneath him once more, practically lunged at Fleet, mounting her over the bench. "UH! Woo, easy there my eager stud..." Fleet said with a grunt as his weight landed so suddenly atop her, then followed with a chuckle.

As he got on top of Fleet, maybe a little too quickly he realized, Rumble felt as his chest ground against hers, sending a thrill up his spine. As his shaft slid up to her rear, he grunted as his hips bucked slightly on reflex...and slid between her legs and along her belly instead, his flare ending at the top of her belly as he 'hilted'.

"A little lower, lover-boy."

Another hump, this one veering off and slipping along her left stifle.

"Try again, aaaalmost got it."

Rumble was mortified, getting more frustrated each time he missed.

“AH! That was my asshole! Maybe we can try anal another day, but for now I need you in my pussy! Aim up a bit, sexy.”

Screwing it up this badly before you're even inside her, huh...?

Rumble took took a deep, fortifying breath and focused, pushing his negative thoughts aside and letting his instincts guide him. He felt a thrill go through him and heard a gasp from Fleet, his flare tapping against her clit's cleft and prompted a wink from it too. "Hah...wow..." Fleet said, already feeling a little lightheaded from the male musk around her, as well as the feeling of a stallion atop her and his cock now at her slit, "...ya finally found it."

Rumble, meanwhile, was more than a bit more nervous now as he slid his hips down a bit more, his flare pressed flush to her vulva. The nearly scalding warmth washing over his tip was mind-blowing already, like when she'd kissed it with her mouth, but times a thousand. Now, though, an entirely different set of lips was giving his flare kisses, her clit winking against it.

Will...will it even fit?

Of course it'll fit, idiot. Foals come out of there too, and they're a lot bigger than your cock!

But what if I hurt her?!

You won't. She's in heat, her muscles in there are completely ready to bring a stallion in, and she's SOAKED. Feel how wet her pussy is!? Just go slow at first and she'll be fine!

But what if...

Despite his breeding instinct telling him to push his hips forward, Rumble was frozen, once more overtaken by his doubts.

I can't do this, I can't do this! Gotta get off her!

Rumble nearly dismounted as he jerked his hips and slid from his target again, but as he looked down, seeing Fleetfoot's calm, pleasured expression and lidded eyes as she looked at him expectantly, he relaxed a bit.

Yes you can! C'mon Rumble, she's waiting for you! She's waiting for her stallion to satisfy her. Are you a stallion, or are you a scared little colt?

"C'mon Rumble, I'm reeeady~," Fleet said in a playful singsong, realizing as he had tensed, hoping to coax the stage-frightened colt atop her into action, "Make me your mare."

Go, go! Find her pussy again and press your cock into her! It's not that hard!

"Just follow your instincts. Fuck me hard, Rumble."

NOW! FUCK HER!

"O~OK..." Rumble said with a slight voice crack, butterflies dancing freely in his stomach as he was now on the precipice of breeding his first mare. Slowly, he realigned their nether regions, his rod pressed softly at her swollen entrance, then just as slowly pressed his hips forwards as his primal mind was screaming at him to do.

Rumble's thoughts blanked as he pressed against her vulva and felt her lips part as she winked, naturally inviting him inside. He let out a breath he didn't even know he was holding as his very tip pressed just inside her, slipping just past her entrance.

Good...just keep going...

With another slight application of pressure, Rumble's flare popped inside Fleet's wet entrance with no resistance, sliding in effortlessly.

W-whoa...

Rumble felt warmth all over his flare, the sides of Fleet's marehood winking and hugging down on him gently, as though coaxing more of him into her. As he pressed his hips forward more on instinct, more of him was taken into her depths as Fleet winked again, her slick wetness welcoming him in as her powerful inner muscles practically pulled him deeper.

"Mmmm-fuck yeah...that's what I need..." Fleet said in a throaty moan. She groaned softly as she felt him enter her, then feed inch after inch inside her, her passage more than lubricated enough to let him enter her receptive body. She felt Rumble's cock filling her more as he kept pressing in, keeping up her soft clenches as she was penetrated.

Rumble was almost amazed as she just kept parting and spreading more for him inside, the heat and clenching tightness around his most sensitive part beyond anything he'd felt before, every inch of his cock within her surrounded and stimulated. The little ribs along her passage felt perfect as they rubbed against his shaft, that sensation telling him he was right where he needed to be to properly breed his mare.

Wow, and I thought her mouth felt good.

Fleet leaned her head back, her eyes closing for a moment at just how great being filled up by her young stallion felt, and how that sensation was absolutely perfect. Their eyes met again as he slid more and more into her. "Mmm...so that's what it's like popping a colt's cherry..." Fleetfoot mused, before sighing as his medial ring slid in, rubbing her clit as it passed, their eyes never parting, "...feels pretty good, huh?"

"H-hah...yeah....holy hay do you feel great..." Rumble said, if barely, his mind going fuzzy from all the pheromones and pleasure hormones going through his brain.

Finally, after nearly a minute, Rumble had finally hilted Fleet, his seemingly perfect-sized member pressing gently against her cervix as his balls pressed to her ass. "Peeeerfect~!" Fleet cooed, rubbing noses with him as they simply savored that first penetration.

Rumble felt some pride at that: he was balls-deep in the warmth of his partner, and his length twitched with satisfaction as he reached her very core, feeling something far inside her pressing to his flare.

Wow, guess I'm not so little after all...

"Well then, you made it as far into me as you can go. Now fuck me."

Nodding, Rumble pulled out until only his flare remained inside her, instantly feeling an intense desire to push back in. When he did, it felt just as good as the first time he'd entered her. "Hah....do all mares feel this good inside?" Rumble asked, prompting a chuckle from Fleet as he began to thrust into her slowly, sloppily. He didn't pull too far out, intending to test the waters first, but jerkily sheathing into her fully each time, feeling her inmost ring smoosh against his flare when he hilted.

"Hmm, I wouldn't know...but I do pelvic exercises to be nice and strong in there for hung stallions like you...so I probably feel at least a little better when it comes to squeezing you," Fleet said as she quickly clenched down on him, getting a gasp and forward jerk of the hips from Rumble in response.

Fleetfoot was feeling much more relaxed now that she finally had a stallion inside her. Sure, Rainbow's tongue and their toys were nice, but nothing could really compare to the flesh and blood stallionhood now spreading her apart, quenching her heat. She felt spread out just right, not an ounce of pain or discomfort to be felt, and she felt Rumble going quite far into her too. He was pressing against that innermost spot that Soarin and Thunderlane had reached too, a pleasant flutter going through her each time he pressed his flat tip to her furthest wall. "Wow, fuck are you deep in me. Feels like you're behind my damn belly button."

"I-is that bad? Do I need to pull out some? I'm not hurting you, right?" Rumble asked in a worried flurry, only getting a little chuckle in return.

"Mm-mm...feels great when a stallion gets that far inside me..." Fleet cooed, looking right into Rumble's eyes as he slowly humped, bottoming out inside her and sending her stomach aflutter each time he bumped her depths. She squirmed a bit as she felt him start to thrust more quickly, more confidently and smoothly, giving a soft moan as she squeezed down on him inside her, her clit winking out just in time for his medial ring to brush against it directly on an in-thrust.

She loved how deep he stayed inside her, making her feel so contentedly full. She loved how he'd nibble on her ears, adding an extra pleasurable tingle down her spine when he did. "So, so perfect..." Fleet repeated as she wrapped her forehooves around his crest, pulling Rumble down to her as she hugged him, "...you're doing such a good job, Ruuumble~!"

"N-not as perfect as you feel, Fleeeet~!" Rumble insisted as he gave a quick succession of thrusts for just a few seconds, exploring how she'd react and if he'd like it. Feeling Fleet's vaginal walls closing in around his rod and a moan from her vibrating his chest, he couldn't help but really love the added intensity himself, then keeping the faster pace.

See? Was it really worth getting so worked up over something that feel this good? Fleetfoot seems to really love it too.

Sure enough, Fleetfoot held an intense expression, her eyebrows knitted, ears folded back, lips slightly pursed and head tilted back, but Rumble could tell it wasn't one of pain. Instead, she was intensely focused on what she felt as Rumble spread her again and again, the relief of having a stallion humping into her when she was so sensitive like this completely indescribable.

"So, how's he feel?"

Fleet jumped a bit and her eyes popped open as she heard Rainbow's voice, having gotten so into the sensations of being fucked that she'd completely forgotten her marefriend was even there. "O-oh...he's good…" Fleet slurred out, sounding like she'd had a pint too many at the bar.

"Hah! He must be good to be making you sound all loopy like that!" Rainbow quipped, but Fleet was feeling too good to care about how dopey she clearly looked and sounded.

"D-don't listen to her," Rumble said, seeing Fleet look dazedly to him as he kept up his hips' movements, "I've never seen a mare look as beautiful as you do now."

"Do you really mean that, or are you just saying that cuz you're balls deep inside her right now?" Rainbow said, a teasing grin on her face.

"N-no, really. You're beautiful, Fleetfoot, and even more so when I get to see you like this. When I...w-when I get to make you feel like this," Rumble said, feeling another strong tingle of pleasure roll through him as her passage rippled around him while he was hilted.

"Aw, stallions get so romantic when they're inside a mare," Rainbow said, smiling, "It's kinda cute."

At a very loud moan, Rumble looked up from Fleetfoot's face and noticed that his brother Thunderlane was within feet of him, mounted on Misty's back and thrusting into her fervently, the couple clearly nearing their own finish lines. He could hear moans coming from the showers as the other members of the team were getting relief of their own together too undoubtedly.

Another cry of passion drew his attention, with Rumble then looking over to the other bench, finding that Soarin was mounted on Spitfire pony-style over the bench, pounding into her pussy as hard as Rumble was Fleet's, clearly nearing his orgasm. Judging by the blissed-out expression and random twitches from Spitfire, she'd already met her own.

Hump, hump, hump, Rumble thrust into Fleetfoot, watching all the other ponies pleasuring and being pleasured by each other. Feeling a rising tingle along his spine and pressure growing in his pelvis; all this stimulation was finally taking its toll on him, and he knew he wouldn't last much longer.

Rumble watched as his brother's hips hitched hard and he stopped hilted in Misty, getting quite a deep, pleasured groan from her and hearing a soft breeding whinny from his brother. He got a good view of his balls pulling up and twitching as his tail started flagging slightly in a rhythmic motion, knowing that with each bob of his tail, his brother was cumming another squirt into Misty’s depths. "Oh f-fuck, it's so warm...so m-much...gonna m-make me...c-cumming..." Rumble heard Misty exclaim, only for his brother's dick to keep pumping, filling his marefriend up well as she started trembling and squirting too.

Holy shit, I just watched my brother cream in his marefriend's pussy and make her cum from it! I...I wanna feel that too. I wanna make Fleet cum with me.

"Mmm, yes, keep going!" Fleet huffed out, bringing Rumble's attention back to her. Her head was feeling light now, her canal purring with sensations. It felt right to be beneath him like that, a mare being bred by her stallion, nothing more to worry about than lying there and letting him cum in her like a good little filly. "Yes, yes, keep going, just like that...by the Moon do you know how to fuck a mare..."

As his pleasure grew, Rumble's pace got rougher and the claps of his balls against Fleet's stifles got firmer, his body laying on top of hers as he humped away, hips moving fast as he fucked her like a mare in heat should be fucked. He could already feel his second load welling up inside him, his pleasure increasing, and knew that meant he was getting close. He fought that feeling, wanting to hear more of her moans and praise, just wanting to feel as if he did an adequate job pleasuring his mare for his first time. Boldly, he nipped gently on her throat, getting a soft gasp from her in return.

“F-faster, fuck me faster!” Fleet demanded, and as she spread her legs more and gave Rumble more access, he only too gladly complied. Fleet moaned to the heavens as his angle changed a bit, feeling as his medial ring now rapidly pass over her winking clit, his growing flare's ridges pressing into her G-spot. “T-that! Just like that! Oh f-fuck yes! R-Rumble...you’re...it's like...y-you're fucking me like a feral stallion!" Fleet moaned out, making Rumble wince.

Did...did I take it too far? Did I hurt her?

"S-still OK?"

"Yes! Yes!" Fleet responded, feeling Rumble starting to get bigger in her, that extra little stretch deep within her telling her he was flaring; that he was getting ready to fill her up.

"Holy fuck, I can see him flaring in you! Look!" Rainbow exclaimed, and when Fleet looked down, she could indeed see a small, long bulge going a third of the way up her abdomen and ending with a larger one, sliding in and out with each hump he gave her. That sight set her lust ablaze, her own hips starting to quiver as she came to the precipice of bliss.

"C-cum in me..." Fleet panted, looking up at Rumble with pleading eyes.

"A-are you sure?" Rumble responded, and though he wanted nothing more than to hold deep as he emptied his balls into her, he worried it was just her heat talking.

"I...I don't know if I can t-take another orgasm without a s-stallion's s-spunk in me...the last one made my n-need for a f-filling even worse. P-please, Rumble, c-cum in me," Fleet said, and the desperation in her voice and the tension in her pussy, and whole body for that matter, told Rumble he was running out of time.

Looking to Rainbow as though to get permission, she nodded with a grin. "Yeah, go ahead, stud. Give her a nice big creampie and sooth her heat, but you better have enough left for me!" Rainbow said with a smirk, "Now show me how good you can fill her up."

At her demand, Rumble slammed harder into Fleet than ever before, a completely different pleasure surging through him as he took her so ferally. He'd never felt quite like this before, wondering what had overtaken him as he humped Fleetfoot like a rabbit buck in rut breeding his doe.

Fleet didn't mind the hard rutting at all, groaning as Rumble bit her ear softly in response to her back arching. A tremble went through her as she involuntarily stiffened up in response, her back legs spreading just a bit more on reflex, with him nipping her neck next.

Rumble leaned over her more, humping so only an inch of him left her each time, his ring constantly rubbing over that lovely bundle of nerves inside her with each. Fleet kept giving soft, quiet moans as he fucked her hard, trying to reach his own end before she did. She gave a soft cry as his teeth found her wing again and gently nibbled on it, her eyes fluttering shut after holding his gaze for so long.

Come on Rumble, cum! Cum in her! She wants you to, do it!

Fleet felt the pressure building in her body, feeling Rumble's flare getting bigger still within her as her passage started to squeeze more frequently, her inner walls flushing with blood and tightening to keep him within her for his penultimate moment, her body demanding his cum in her. She kept rocking her hips back into his thrusts desperately, her clit winking every second and mashing against his sheath with each thrust in, "...I'm so...close. M-make me...c-cum Rumble, cum in m-me...please."

Before he could stroke himself to his finish inside her, Rumble heard a cry of pleasure from Fleetfoot as he humped in hard one last time, feeling her hind legs lock around his croup, stilling his thrusts and forcing him to stay hilted in her. Watching her eyes roll back before they closed, he could feel her trembling beneath him, almost like she was having a seizure, and that was to say nothing of what her pussy was doing. He felt as her insides went crazy on his cock, rippling tightly from its base to swollen flare, holding him in place as it milked him and squirted her marecum all over his balls.

Rumble felt his own finish approaching as his broodmare's pussy was kneading him for his load...but he just couldn't get over his precipice, feeling his climax fading back again. Perhaps it was his nagging fear of getting her pregnant despite what his brother had said, the potion boosting his longevity during sex, or the fact that he may indeed have an earth pony in his bloodline, but his endurance held even through Fleetfoot's rather long orgasm.

Rumble felt as Fleet’s contractions gradually slowed, felt her panting her hot breath on his neck as she recovered nearly a minute later, her inner hugs on his stallionhood now slowed to a rippling instead of outright grasping him. He felt her giving little kisses of gratitude on his neck, her legs loosing their lock from around his rump, though she was quite happy when his still-hard cock stayed nestled between her hips.

"Wow, damn, haven't seen her cum that hard from a cock in a while," Rainbow said, having watched and rubbed herself throughout, quite impressed with how he'd performed for Fleet. As she noticed a distinct lack of stallion cum when Rumble soon pulled out with a moan from him and wanting whimper from her, and the fact he was still completely erect, her eyes went wide. "Holy buck! You still didn't cum? You sure you're not just an earth pony with wings?!"

"N-no...I don't know why I..." Rumble started, dismounting Fleet and standing to the side with a sharp exhale, "...didn't yet, but—" Rumble gave only a grunt after that as he found himself bowled over and forcefully pressed onto the bench seconds later, a nearly manic-looking Fleetfoot looming over him as he took her previous position on his back.

"You're gonna c-cum in me, or I'm gonna ride you until my heat's over, whichever happens first!" Fleetfoot snarled ferally, before climbing over Rumble and lining them up again griffin-style. Judging by her expression and frazzled mane, he was inclined to believe she really would ride him for a week or two straight if he somehow didn’t cum in her. Not that he minded going again, of course.

"O-OK, go ahead. You can...ride me," Rumble said, hoping maybe she could make him cum this time.

"Whoa, never seen her get like that before, heat or not..." Rainbow said, her tone a bit jealous. Seeing what he'd done to her usually cool-headed marefriend only made her rub herself that much harder, warming herself up for her turn with him.

Using her forehooves on Rumble's chest for balance, Fleetfoot used a wing to line Rumble's tip up with her pussy as she squatted over him, before pressing her hips back. Letting out a lewd moan, Fleet felt as Rumble's still-swollen flare popped into her again, his thick member spreading her walls as she sunk herself onto him. As soon as he'd bottomed out again, she pulled right back up, wasting no time in ramming her hips down to meet his again.

Rumble knew he wouldn't last long now as Fleet bottomed out for the fifth time. He was already feeling the distinct pulsations and tightening in his pelvis, like a guitar string being wound tighter and tighter, and he knew it wouldn't be long before the string broke and he finally finished.

Rumble watched as Fleet rode him, able to see every part of her from this position; watching her swollen, soaked pussy swallowing each inch of his stallionhood, her lips pressing to his sheath with each drop, the slight bulge his cock made in her, and the slightly larger one his flare left as he simultaneously felt it drag through her, her blissed out expression as she rode him like a griffoness seeking a clutch of fertilized eggs from an unwilling tom.

Rumble reached up a hoof and softly pressed it to her belly, able to feel his cock moving through her flesh, that sensation of feeling his hoof on his own member while it was still inside her both incredibly arousing and fascinating.

"C'mon...c'mon..." Fleet said impatiently, completely lost to her instincts, wanting nothing more than to feel this stallion's hot load flooding her womb. Each second without his cum inside her was nearly torture, her lower belly an inferno like she'd never felt before with another stallion, and she knew that his load spurting inside her was the only cure.

Rumble focused on how good her hot pussy felt squeezing around him as she jackhammered herself on him, following her motions as they humped and ground into each other. He could swear she’d gotten even warmer inside somehow as he wrapped his hooves around the curves of her stifles, giving him more leverage to pull her deeper onto him. He thrust upwards as she dropped down, once more losing himself to the feelings of her tightness and warmth surrounding him. He felt the inevitable on the brink.

After nearly a minute of her riding him and him thrusting up into her, Rumble felt a tightening in his pelvis, a further swelling of his flare, and stiffening of his cock that told him he'd just passed the point of no return.

OH FUCK YES!

"Yes, YES! Rainbow, he's..." Fleet said as she felt him fully flare and stiffen, pulsing hard inside her, before she too tensed up when she felt him throb. Rumble's cock exploded like he'd never cum before in his life. Huge, powerful bursts of virile semen blasted into Fleetfoot’s fertile insides as he jerked his hips up forcefully while she leaned back and balanced to be nearly upright, pushing down on him as hard as she could, putting her full weight on him and forcing him deeper still. Both trembled with the force of their releases, and Rumble felt as Fleet's new position and gravity pressed his flare past her relaxed cervix as he started coating her womb in cum.

“...OH GOOOOOOODS!”

Rumble had never felt such pleasure, his mind blank save for the feelings of Fleetfoot's walls rippling over him, her inmost wall bypassed by his swollen flare, and the involuntary pulsation in his pelvis. It felt like her canal was suckling him as he just pulsed and pulsed inside her, feeling a new tightness behind his flare. It was rapture as he grasped her hips and held them to his with all his might. He held her in place as he unloaded into her, hugging her around her middle and burying his muzzle into her chest as he gave her all he had, and as far into her as he could.

Fleet, meanwhile, felt Rumble's flare spread something even deeper inside her, and that sensation of a stallion bypassing her deepest barrier triggered another intense orgasm for her. She felt as ribbons of Rumble's warm, thick, life-giving cum washed into her furthest depths, with both ponies grinding their crotches as tightly to the other's as they could.

Fleet's pussy did its best to claim everything it could from him after being denied it for so long, clenching and clutching Rumble's pulsing stallionhood with each warm squirt he'd give her, sending her to a place of pleasure she'd never been before. She'd never felt as complete as she did then, as pump after pump of his seed whitewashed her womb, his throbbing cock cooling her heat in the way only a proper breeding could.

Even after he stopped pumping cum into her, even after he stopped dry-pulsing, even when she finally stopped squeezing on him, Fleet still held Rumble deep inside her. She loved the feeling of his huge flare keeping all of his spunk dammed deep within her furthest parts, knowing it was likely sealing her cervix from the inside with how far she felt that swollen tip and pleasant pressure inside her. She could feel her womb gently swollen with the sheer quantity he’d put inside it, making her more than a little impressed by his output.

As she rested with the young stallion, Fleet felt a profound satisfaction, one she’d not had until that moment; not even when Rainbow had finished her half a dozen times in a row, not even when Soarin had cum inside her during a previous heat and yet it had still persisted after. Her estrus was completely and utterly done. She felt not a flicker of the burning of before, not a twinge of want or itch of need; just a satisfying, filling warmth radiating from her core, right where Rumble had left it.

Fleet sighed happily, her mind completely clear of her breeding urges for the first time since her heat had started days ago. She found herself smiling at that utterly relieved and soothed sensation in her lower belly, it feeling as though somepony put aloe vera cream on a bad burn deep inside of her.

She soon collapsed onto Rumble as they panted together in their afterglow, pulling his flare from her cervix, but still feeling it completely hard just outside of it as her muscles flittered over his mating plug, and for the moment she knew elysium. “H-hah...y’did good kid…s-sooo good...” Fleet mumbled weakly as she hugged Rumble, cuddling with him, just wanting to be close to her mate after such an intense breeding session.

“Awww...time for the aftersex snuggles! Those are almost better than the sex itself! Almost.” Rainbow gushed, honestly feeling rather emotional at the moment despite her typical tomboy facade. All while Rumble had filled her marefriend, she’d kept teasing her own arousal higher, keeping herself edged. It always felt better when she finally popped after she’d edged herself a few times, she’d found, and she was going to make the most of her first time with Rumble.

After a couple of minutes of cuddling and nuzzling each other, their hooves gently rubbing the other’s cheek or mane or back, rubbing noses more than once, Fleet finally dismounted Rumble with a displeased whimper from her as his flare deflated and her inner muscles finally relented enough for him to slide out. She gave a quiet grunt as as she felt his still-swollen flare slide from her with a loud slurp, and as it did, a virtual flood of his cum came from her, streaming down to the floor and all over his crotch and balls too. “Holy shit…” Rainbow exclaimed, “...how did you put that much in her even after cumming once already?”

“I dunno…” Rumble said as he laid on the bench, looking up at the well-fucked mare still draped upon him. As she soon got off him and let him up, he saw the river of cum still flowing from Fleet’s slit and the puddle it’d formed under the bench, and was amazed at how much he’d gushed into her...and was once more thankful she was on birth control. “...but holy shit did it feel good putting it there!”

“H-hah...I second that…” Fleet mumbled as she laid down again, squirming a bit as she rubbed a hoof over the shrinking lump Rumble had left in her, “...feels sooo good being all full of your cum like this...”

“Hah, I bet…” Rainbow said, knowing just how good it felt to take a nice big creampie deep inside her womb while in heat, and imagining it felt just as good for a stallion as he put it there.

Hearing a cry of pleasure from nearby, Rumble looked over, seeing Soarin press his hips to Spitfire's as she started trembling, seeing his balls pulsing and tail bobbing as he clearly dumped his load into her. Rumble could see him giving shallow little humps as he came, his hind legs trembling, and of course their expressions of pure bliss.

After a tense few seconds, Rumble saw a little bit of white leaking from Spitfire’s crotch to the ground, in awe as Soarin apparently overfilled her. After some cuddles, rubbing noses with each other and kissing, he dismounted his mare a minute later, and a stream equal to Rumble’s oozed from her. “Well, looks like those potions work pretty good, huh?” Rainbow asked, startling Rumble from his stupor. “Damn, glad I’m not the one cleaning the locker room after this…”

“O-oh, yeah…” Rumble said, not sure whether to laugh or be disturbed by the fact he had to help clean all this up...only then noticing how close Rainbow was to him, feeling her side brushing to his.

“I can see you’re still hard...wanna see if you can take me flying now, or you just gonna leave me hanging after fucking my marefriend?” Rainbow teased, “All that cum in her pussy, stomach, and on the floor, I’m surprised you still have any in you.”

I am too...that’s a hell of a potion!

“You don’t know how horny seeing you cream so much inside her like that made me...actually, ya know what? How about you let me show you.”

Before he could respond, Rainbow was already in front of him and out in the main room, turned around and her tail flagged aside. Rumble could indeed see how worked up she was, a thick string of her fluids drooling down to the ground, and several strings of the same attaching her swollen vulva to her tail. Rumble realized she looked as aroused as Fleet had been, and she wasn’t even in heat!

“W-wow, watching us...did that to you?” Rumble asked, unable to tear his eyes from her swollen, soaked crotch as it winked slowly, inviting him to breed her next.

“Uh-huh...told ya you’re a stud,” Rainbow said, “I watched you perform, now how about you come and stud me? I want what she had, with extra cream filling!!”

Author's Note

Time to ride the Rainbow!

Also, yes, partial or even full cervical penetration in real-life equines (and many other animals for that matter) is completely normal and expected, and may actually help promote a successful conception (though in this case, it likely just feels really satisfying). Unlike in humans, it's likely not painful or uncomfortable at all.
