Rainbow rocked her hips back and forth, her dildo fully seated within her. It was designed specifically for mares in heat, as it was thick, long, and complete with a small knot at the base. Her favorite and most-used toy used to have the strongest of suction cups on the bottom, but it had broken off last week. She’d spent most of the last two weeks locked in her bedroom, trying to keep her mind as clear as she could. Soarin tended to her needs as best he could, but there was only so much he could do without risking getting her pregnant.

Furiously rubbing her clitoris with a hoof, Rainbow tried to cum, even imagining herself riding Soarin’s cock as he whispered in her ear how much he wanted her to cum for him, but it was all for naught. She cracked open her eyes and saw Soarin propped up on the pillows at the head of the bed, his hind legs splayed as he rested on his back. His cock was already hard, leaking no small amount of precum as he watched her play with herself. As the feeling of her once-building orgasm started to fade away, Rainbow let her hoof fall to her side in defeat.

Flopping down on the bed, Rainbow groaned as the dildo slipped from her folds, her juices darkening the bed sheets. “Ugh! Why can’t I get off?” she asked to nopony in particular. “And why is my heat cycle lasting so long? It’s been almost three weeks now, and it’s starting to drive me crazy!” She pulled a pillow over her head and screamed into it halfheartedly.

“You want me to help?” Soarin asked, sliding across the bed. He nuzzled his lover’s cheek under the pillow and kissed her neck until she responded. “I can fuck you as long as you need, then pull out before I cum.”

“You know I’d love that, Soar’, but I don’t want to risk it.” She pushed the pillow between Soarin’s forelegs and laid her head on it, looking up at him. Rainbow lovingly nuzzled his breast, then let out a long sigh. “I’m sorry I haven’t been helping you out lately, it’s just... you know how things are.”

Soarin nodded. “But what if we wanted you to get pregnant?” he asked softly. “I hate seeing you go nuts over this, and I think we’re ready to have a foal.”

“Wait...” Rainbow sat up and rolled over onto her stomach. “Why do you say that?” She wanted to hold his gaze, but found herself staring at his throbbing length instead. A shiver ran down her back as she imagined him pumping her full of his potent seed. She only looked back up at him when he laid a hoof on top of her own.

“We have our own house now, we’ve been together for over three years, and we’re in a great place financially. On top of that, our wedding is next month, and I think you’d look adorable with a little baby bump.”

“But what if the dress we just spent so many bits on won’t fit?” Rainbow’s ears flicked back. “I don’t wanna look fat in our wedding pictures, either.”

“Well, there’s a difference between being fat and having a foal grow inside of you. I know you’ve worked hard all your life to stay in the best shape you can, but I really don’t think the foal would grow fast enough for it to make you look fat. Besides, just think about it! We’d be able to spoil our little foal rotten.” Soarin brushed some of Rainbow’s unkempt mane out of her face. “I think you’d make a great mother, too...”

He leaned forward, capturing Rainbow’s lips with his own. A few moments passed before she allowed him entry into her mouth, their tongues dancing a quick tango of passion. Feeling a burst of confidence overtake him, Soarin stood up without breaking the kiss and pushed Rainbow onto her back, then laid on top of her, his weight pinning her onto the bed.

Rainbow broke the kiss and stared into his eyes, panting softly. She blushed as she felt her lover already standing at half-mast, growing harder with each passing second. She felt Soarin lay a trail of kisses down her neck, stopping just above her belly. Her heart raced in her chest as she considered what Soarin had just said. “I... think you’d make a good father, too.” She wrapped her wings around him and pulled him down, pinning his length between her hind legs. “But are you sure you’re ready to start a family? Being a parent is a huge responsibility.” She slowly moved her hips back and forth, the bottom of his cock rubbing against her clitoris in all the right ways.

“Well, the real question is, are you ready for this?” Soarin nuzzled Rainbow’s cheek. “I’ll be there every step of the way, but I think you already knew that.” He placed his front hooves on either side of Rainbow’s head as he readied himself.

Rainbow bit her bottom lip, then meekly looked into Soarin’s eyes. “Yes, I... I think I’m ready, but...” She glanced away as a blush tinted her cheeks.

“What is it?” Soarin asked with a lifted eyebrow.

“Can you get up real quick? I need this moment to be perfect.” Rainbow prodded his firm chest with a hoof, trying to ignore his heady, musky scent that always drove her wild with lust. When Soarin slid off of her, an obvious needy look in his eyes, Rainbow rolled over onto her stomach and pushed herself towards the end of the bed until her hind legs slipped off. She pulled a pillow over to hold onto with her forelegs, then spread her hind legs wide. She felt Soarin nuzzle her tail out of the way, exposing her fully-aroused slit to him.

“Such a perfect view...” Soarin sat down behind Rainbow and held her tail aside with a hoof. He suckled Rainbow’s clitoris like it was a nipple, flicking it in random intervals with the tip of his tongue. Feeling a little of Rainbow’s arousal stain his muzzle with its sweet and highly-arousing scent, he lapped at her opening, focusing solely on his partner’s pleasure. “For such a perfect mare...” Soarin breathed, his warm breath teasing Rainbow’s puffy lips.

“You’re such a sweet-talker, aren’t you?” Rainbow asked as she panted softly. “Now mount me before I change my mind and go back to the dildo!”

Soarin’s eyebrows furrowed. “Wait, if you’re not a hundred percent on this, we totally don’t have to do this. At least, not right now. We can wait till next summer if you want us too.”

Rainbow rolled her eyes and flicked Soarin’s muzzle with her tail. “That was a joke, you stud. But seriously though, it’s not nice to keep a mare waiting.” She spread her legs a little wider, letting the bed support her weight instead of her legs.

“Oh, don’t you worry, my love,” Soarin laid a gentle kiss on Rainbow’s vulva, his tongue briefly flicking out to run up and down each lip. “I’m going to do all of the work, so you just lay there and enjoy it, alright?”

“Heh, sounds good,” Rainbow murmured. She felt Soarin mount her, his hooves resting just in front of her wings. His cock rested on her slit, barely spreading her. “W-Wait!”

“What? It’s not even in yet!” Soarin joked, nuzzling Rainbow’s neck.

“I thought of a better position,” Rainbow said. “Just gimme a few seconds...” She rolled over onto her back and propped her head up on the pillow. “There! Now...”

“Hm?” Soarin looked down upon her, a small grin on his face.

“Now we can look into each other’s eyes as we do it,” Rainbow said much too quickly. She blushed so hard she thought her cheeks were going to burst into flame. “I really don’t like admitting stuff like this, but...” She reached up with a hoof and pulled Soarin down into a brief kiss. “I love you, and I think it’d be kinda romantic if we looked into each other’s eyes as we finish.” She looked down, only to feel a gentle hoof guide her head back up.

“You have no idea how much I love it when you say things like that, Dashie.” Soarin laid a quick peck on Rainbow’s cheek. “So... I dunno if you noticed, but I haven’t cum in the past week. I thought that you would agree to have a foal with me, so I... I made sure that I’d be as pent-up as possible if the moment came.” He pushed his tip inside Rainbow’s entrance and stopped. Looking his lover dead in her eyes, he whispered, “You ready to become a mother?”

“Only if you’re ready to become a father,” Rainbow whispered back. She wrapped her hind legs around Soarin’s flanks and locked them behind him. “So listen... I don’t know if this is true or not, but one of my friends told me that the chances of getting knocked up increase if I cum.”

“Gods above, I love you so much...” Soarin pushed himself inside. After watching Rainbow ride her dildo in front of him for most of the evening, he was more than ready to show her why the real thing was much more satisfying. He didn’t mind that she used dildos bigger than him mainly because he got to watch his lover and best friend squirt all over him.

It also helped that she usually asked him to eat her out during her sessions, too.

He felt Rainbow clamp down on his length before he could get up to his medial ring. “Everything alright?”

“Y-Yeah...” Rainbow panted. “Keep going; I know I can take the whole thing...” She rubbed the side of Soarin’s foreleg with a hoof.

“Hehe, yeah, I’ve seen you do it.” Soarin rocked his hips back and forth, coating the first few inches of his cock in Rainbow’s wetness. Feeling Rainbow push him in with her hind legs, he stopped thinking and simply acted, letting his primal instincts take over. Soarin smiled down at Rainbow, loving the way her face changed as he pushed inside of her. Her mouth formed a small ‘O’ as his medial ring slipped past her labia, her pussy still as wonderfully tight as ever. “Almost there, my love...” he whispered. Soarin stopped, readjusted his stance, then pushed the rest of his length inside in one go, his balls slapping against Rainbow’s butt cheeks.

“Ah!” Rainbow cried out, her eyes rolling into the back of her head. Her ears flicked down as her wings started to unfurl.

Soarin loved the way her nose twitched as she fully enjoyed the sensation of being stuffed full of his cock. As he gyrated his hips, hitting all of Rainbow’s buttons in her love canal, he booped her nose with his own, making her open her eyes. She smiled up at him and nodded. Spreading his forelegs, Soarin pushed himself up and pulled back only to ram back inside of her. He felt her squeeze him hard, using her hind legs to hold him inside of her. Soarin tried to pull back for another thrust, but found that he was locked in place.

Rainbow opened her eyes and noticed the look of confusion on Soarin’s face. “I... want to... try... something different... tonight.” She let her forelegs curl up on her chest, then took a couple of deep breaths. Rainbow forced her pussy’s muscles to relax as much as she could, then clamped down with as much force as she could muster. She did that over and over, feeling the faintest hint of an orgasm tease her as it slowly but surely built up deep within her core. Rainbow adjusted her grip on Soarin’s flanks and pulled as hard as she could, making sure that he was as deep as she could take him.

“Oh...” Soarin groaned deeply, arching his neck as he felt Rainbow’s pussy ripple along his length. His tip flared up inside of her, signalling that he was going to cum soon, but he forced himself to hold back. Knowing that Rainbow needed more than just a good fucking to cum, he rocked his hips back and forth, teasing her winking clitoris with his groin. He heard Rainbow let loose a high-pitched yet soft squeak, a sound he knew that she made when she was getting close. “R-Rainbow, I think I’m g-gonna...!”

“Shh... I know,” Rainbow whispered. “I want you to cum inside me... to give us a foal!” Her pussy’s muscles grew sore from over-exertion, but feeling her lover’s cock throb inside of her tight passage pushed the pain away. Soarin picked up the pace, his cock able to only move back and forth an inch or so. She felt some of her wetness slip from the tight seal that her entrance made, slipping down to darken her tail. Rainbow bucked her hips up into Soarin’s groin, wiggling back and forth all the while to push herself up to the edge. Wrapping her wings around Soarin’s back, she yanked him close and held onto him for dear life as she slipped over the edge.

Rainbow whimpered as wave after wave of sheer pleasure ran through her body, all emanating from her core. She felt herself clamp down on Soarin’s cock one last time, harder than ever before. Burying her face into his chest, Rainbow couldn’t help but let out another cute squeak, quickly followed by a loud moan that was muffled by Soarin’s fur as she felt her insides warm with his cum. She couldn’t help but let her hind legs slip from Soarin’s flanks as she felt her extremities go numb. Her pussy felt so sore, yet it tingled so wonderfully she’d pay no small amount of bits to keep this moment from stopping.

She felt some of his cum slip from her folds. Can’t let... any of it out! Gotta keep... as much... inside! Rainbow thought, struggling to think through the haze in her mind. With a renewed vigor, Rainbow used her hind legs to push Soarin as deeply inside as she could then pushed her hips up into his groin, feeling his balls, resting between her butt cheeks, twitch with each and every shot that they pumped inside of her.

Soarin collapsed upon her, panting heavily. Rainbow wrapped her forelegs around his neck, panting equally as heavily. After several moments, Soarin pushed himself off of her, pulling his softening length out. Though before his tip left her folds, he grabbed her butt with his hooves and lifted it up, his cock finally slipping out with a soft pop. He propped Rainbow’s butt up on his chest, then pushed her further onto the bed so he could lay down. As he watched his cum trickle out of Rainbow’s engorged lips, he placed a hoof on her entrance, stemming the flow. His legs trembled from the strength of his orgasm, but he still found enough strength within him to do what was necessary.

“Wha... What are you doing, Soarin?” Rainbow asked, eyeing her slightly-distended belly. She rubbed the bump with a hoof, wondering if this was what it would look like when she had a foal growing inside of her.

“Making sure that you get pregnant,” Soarin said, kissing Rainbow’s inner thighs. “I read in a magazine the other day that holding you up like this increases the chances of conception, and with you nearing the end of your heat cycle...”

Rainbow nodded slowly, then giggled softly. “Heh, I was right. You’re going to be a great dad.”

His ears perked up a moment before he chuckled, hiding his growing smile with his other hoof. “I guess we didn’t really look into each other’s eyes as we finished, eh?”

“Oh, don’t worry. We can always do that the next time I go into heat!”

“Wait, you want more than just one foal?”

Rainbow’s eyebrows furrowed as her smile faltered. “Y-Yeah. Wouldn’t you want our foal to have a brother or sister to play with?”

Soarin glanced away, then looked back at Rainbow with a relaxed smile. “Yeah, that sounds like a wonderful idea.”

“Awesome...” But what if I had twins? Feeling her back grow sore, she scootched back and sat up, letting Soarin’s cum seep out of her, coloring her vibrant tail white. “Heh, think we should go clean up?”

“Nah, leave it; I think it’s hot.” Soarin weakly used his wings to help push him next to Rainbow. Sliding under the sheets, he wrapped a wing around her midriff and pulled her back up against his stomach, taking care not to pinch her wings. “Out of all the stallions in Equestria, I’m truly happy that you chose me to be your husband...” he whispered, nuzzling the back of Rainbow’s head.

“Oh? Why’s that?” Rainbow flicked her tail to lay on top of Soarin’s.

“Because you’re the one that stole my heart at the Grand Galloping Gala all of those years ago. I couldn’t think of a mare more special than you to spend the rest of my life with, Dashie...” He wrapped a foreleg over hers and held her like a storm was doing its hardest to rip them apart. “I love you more than anything in this world.”

Rainbow felt her heart blossom into a fiery rose. She rolled over and tucked her head under Soarin’s chin, squirming as close to him as she could. “Hearing you say that makes me know I made the right choice... as if there was any other stallion who could compare to you, my love. Also... I guess we’ll know by tomorrow if you got me pregnant. If I’m still in heat, I’ll just ride you until your awesome cock falls off or until your balls are completely empty, whichever...” A yawn made her pause. “Whichever comes first. So... I have no idea what to expect if I hopefully get pregnant, but my heart tells me you’ll always be there for me...” Rainbow sighed She laid a quick peck on his neck, then closed her eyes as his warmth lulled her into a fitful sleep. “I love you,” she whispered, tears of joy tickling her cheek as they dripped onto her leg. “More than you’ll ever know.”
