Brad trailed his hoof along Twilight's horn. "Where'd Bella wander to? She's usually around for snuggles."

Twilight was carefully inspecting every part of his body. "She decided to explore Ponyville. Said she wanted to introduce herself as a pony instead of a horse."

"Fair." Brad tensed up, wings going stiff behind him. "Wait. Does that mean I have to?"

RC thumped against his other side. "You are new to the whole pony thing. We aren't humans. We put this stuff out there nice and clear."

Twilight darkened, her face heating up with a blush. "You, um, really didn't notice?" Brad's clueless face was hint enough. "We are in estrus." She lifted an ear at Brad. "Unlike an animal, we are sapient, and can decide what to do about it, and ourselves. It does increase our libido all the same. Fortunately, or unfortunately, we have a specific partner already at hoof for such things."

Brad twitched an ear back and forth. "I think I remember that being explained. Huh. Wow, you do smell good." He took a deep breath, sighing gently as he rubbed along Twilight's flank, just to nuzzle RC, snout to snout. "Both of you. Is that what I'm smelling?"

RC reached out with her hoof to lift his chin up. "Yeah. It is. And we're going to get a lot worse before it's over." She gave him a predatory look, licking over her lips. "Though our sweet stallion can take care of us." She turned away, tail flipping upwards. "In a way only a stallion can."

Brad's head was already spinning, but he followed his instincts, pressing in close. The aroma had been there all along, and he had been responding as expected. His wings were spread, and he was pressing right in against her with a growing firmness. He squeaked as he felt something grip him down there.

Twilight's horn was glowing as she made a stroking gesture, her magic following along. "I'll help." As promised, she guided him towards her waiting entrance. "We both want a turn, maybe a few, tonight."

Brad didn't feel like arguing, letting the magic guide him. He sank into her depths with ease, the mare's body accepting him entirely. The motions were nothing like his old hips, but the sensations were amazing all the same. Her body was drenched on the inside, making each movement a moment for both to shudder and groan. "Rainbow..."

RC whickered, a gentle laugh. "That's good, stud. Keep going."

Brad huffed softly, pushing deep into her depths, pressing firmly up against her. Her wings fluttered, the mare's head lolling to one side. He spread his in response, finding their mutual motions could help smooth the process as he rocked into her. His balls felt full and tense, eager for the task. "W-wait, if you're, oh, what if you end up with a foal?" He was quite sure this was going to lead there.

RC rolled back against him, panting lightly as he filled and emptied her with each thrust. "Good! I'm ready. This family is ready to grow." She kneaded at the bedding with her hooves. "I won't, mmm, let Bella race ahead of us."

Brad gave a good thrust that took them both by surprise. RC shuddered, a short whine escaping her. He could feel her body gripping at him, holding him in tight as if she intended to milk him then and there. He couldn't hold back an instant longer. With a firm push, he shoved himself deep within and let go, erupting into her depths. The mare's eyes rolled as he throbbed into her, seed splashing against her walls with enough force to make her twitch around him.

Twilight gently stroked either of their sides. "Mmm, that looked proper. Now, Brad, you still have more to do, and I imagine you're a little out of breath too. Why don't we take a break?" She leaned in and gently kissed Brad on the neck. "I'll be waiting for you."

Brad panted softly and pulled back, slowly slipping free of Rainbow with a low pop and dribble. He fell back onto his haunches, then flopped to his side. "Damn you mares," he laughed out. His mild complaint died entirely when Twilight when in for hugs. He wrapped his hooves around her, pulling her against him. They rolled a little, coming to a rest with her on top.

"Hello," she whispered, pressing in to nuzzle against his neck. "As a unicorn, I have a few other tricks I fully intend to utilize." She grinned at him, her horn glowing. She lifted into the air, levitated by magic alone. She floated down atop him, easing onto his shaft. She pushed until they were one, letting out a gentle sigh as she sank all the way down to the base. "I will stay on top, if you please."

Brad shuddered and nodded, holding her with his hooves as she started to move. Her body was just as slick as RC's had been, and yet it felt like a different kind of riding. Being forced to let her do the majority of the movement was different, but quite pleasant, and relaxing after the last round. He spread his legs and wings to either side. "You can use me as much as you like." His head spun a little. The scents of them both were getting stronger.

A soft squeeze made him jump as something groped his filling orbs. He could see her horn glowing, giving a hint as to who was responsible. That glow extended up along her belly, then down beneath her, clutching at him gently. It was almost as if there were a second mare atop him, encouraging his growth. The sensation of being touched there even as he plunged into Twilight's hot depths was new and entirely unexpected.

Brad groaned, holding Twilight closer. She was moving slowly but steadily, each motion sending another jolt through him. His senses were on overdrive, smelling more of her scent, tasting her tongue as they kissed, feeling everything all at once. "Y-you want a foal too?"

"I don't want to be left out." She huffed gently. "It is, perhaps, a foalish reason, but you have three wives, and two of them are moving to have a foal. I don't want to be the only one not experiencing this." Her eyes glazed with desire as she ground against him. Her inner walls rippled and shivered along him, pulling at his flesh. It felt like she was stroking him all over inside, even though she was doing very little, at least physically. Her horn shimmered as her magic worked at him, teasing him constantly. "As your princess, I command that you inseminate me."

Brad blinked, confused a moment. "This isn't, mmmf, arti—" As if in complaint at his nerdy speech, tension exploded and released through him, pumping into her depths and filling her up. He could feel her body tensing and relaxing around him with her own peak. They came as one, bodies working to make it last as long as they could, pushing to the limits of their pleasure.

He fell back, twice as fatigued from the second burst. "That... that was even better." He wheezed softly for air, coming down from his peak.

Twilight hummed gently, nuzzling him. "I love you too, and yes, it was." She curled a hoof to her chin. "But I may be biased. I could only distantly feel the passion and love you two were sharing with one another. It was intoxicating, but nothing like the actual thing."

"Tell me about it." RC was watching the two, wings flapping gently. "That was incredible to watch. My turn next time?"

Twilight smiled and leaned back against Brad's chest. "Yes, but give him some time to recover." She reached over and stroked over his balls. "I'm afraid that these are empty at the moment, and he's already tired. We have all night, so we can take our time."

Brad nodded. "Yeah. That would be easier for my poor body."

As Twilight promised, they took their time with him. With his own mind starting to understand more of how it was to be a stallion. That didn't make the look RC was giving any less concerning. "You have something in mind?"

"You bet I do." She flapped her wings with a grin. "Something only pegasi, and I guess alicorns, can do."

Brad leaned in close. "But Twilight—"

"—Is already asleep." She nudged at Brad, pushing him away from Twilight, who was indeed snoring gently. "Come on, we don't want to wake her either."

Brad moved over with RC, letting her push him into the corner of the bed. "Alright?" He blinked at her. "What are you planning, anyway?"

RC nuzzled up against him. "Follow me." She led with a lively trot from the library. "We pegasi have a specific set of talents. Flying is involved in most of them."

Brad blinked. "Wait. How does flying—"

"Quiet, stallion. I am in charge, and I'm saying it's time to fly." She spread her wings and leaped into the sky.

Brad took a deep breath and followed, finding his wings doing the work for him. It was like flying, with more third dimensional action. It still amazed him how much he was getting a grasp on it.

RC flew in close to him, brushing his side with her hooves. "Now, two choices. We do it in the air, which involves a lot more skill, or we find a comfy cloud."

"Cloud please?" Brad wasn't sure about his abilities yet. "I'd hate to fall out of a rut."

RC laughed gently. "You would be fine, but I get your meaning." She rolled her eyes. "But I will hold this against you, coward."

Brad huffed softly. "Yes, I'm afraid of doing it wrong."

RC shook her head. "Fear is not what makes a great flier." She found a good spot and dropped, landing with a gentle bounce on a nearby cloud. "Nice, soft, and private." She turned around on the cloud with a nod. "Perfect for making more pegasi." She laid herself on it, tail flipping high. "What are you waiting for?"

Brad dropped heavily to the cloud's surface, sinking in slightly. "I was thinking." He walked up to her and nosed against her exposed privates. "I've never been a dad before, and now I'll be three at once?"

"And I never was a mom before. We're all learning." She gently smacked him with her tail. "More rutting. Less talking."

Brad snorted and took her with one smooth move. His hips moved with a lot more sureness this time. It didn't hurt that she was more than ready to take it, her body slick around him. They met belly to belly, rocking against one another side by side on the soft embrace of the cloud. Their motions sent ripples through the vapor.

He held her close, his motions growing stronger. Having done this twice before, he was learning fast how to make it work for him, and for her too. The two called out, knowing nothing but a passing bird was likely to hear their cries.

Brad's wings fluttered behind him as he thrust harder, his balls tensing once more with their duty. "R-RC!" He let himself go, pounding into her as he exploded. His body spasmed as he held himself there, pumping thick gouts of stallionhood into her.

She wrapped her wings around him, laughing as she nuzzled in close. "You have a hair trigger. I'm guessing it's being a new stallion, not at all used to being around ready mares."

Brad grumbled softly. "I would argue, but the evidence is a little stacked against me."

RC giggled lightly. She pulled back, letting his spent stallionhood flop free. It was a clear night out, and the moon was full out here, away from the lights of Ponyville. They were alone with nothing but the moonlight and the soft bed of cloud beneath them.

RC settled in against him, wings closing down. "That was unfair of me, maybe, a little. You were already tired." She kissed around his ear. "Thank you for putting up with me."

Brad closed his eyes, nuzzling in close. "It was a pleasure."

She hugged him tighter as they both drifted into sleep.

Author's Note

Continuing this, the mares find another use for Brad as a stallion. Bella may have beat them a little, but that won't stop them.
