A loud stamping sound and a whinny made him open his eyes again. He looked up, turning his attention in the direction that the sounds had come from. What he saw was Paulette, standing in her stall and staring at him and Aideen.
"What's the matter, Paulette?" he said, frowning and standing up. He walked shakily out of Aideen's stall, going to the door of Paulette's. The young Ponyta mare came up to him, her nose twitching as she sniffed at him. While the Rapidashes had a good amount of height on Colby, Paulette stood at more or less the same height as the human, and her nose was right at chest level. He was certain she could smell her mother on him. She was clearly agitated in some way.
Sighing, certain that his need for sleep was going to be delayed a bit longer, Colby unlatched the door of Paulette's stall and stepped inside. As soon as he got in, the Ponyta's nose dipped down to his groin, sniffing around at his cock and balls. Colby immediately felt himself starting to stiffen again.
Belatedly, he recalled that Paulette had been fidgety earlier in the evening, almost as though she was going into heat. With a fresh surge of energy, Colby had an idea enter his head. Maybe Paulette wanted the same thing that Aideen had just gotten?
"Did you see what just happened over there?" Colby asked her. She didn't make any sort of reply, but just kept nosing around at his cock, which kept growing in response. Before long he was fully erect again, and more than a little bit interested in seeing what the smaller Ponyta mare had to offer. "You want to have some fun, too, Paulette?"
Paulette turned a little red, and looked over the wall dividing her stall from her mother's guiltily. After all, Aideen had gotten to Colby first, so she might not be willing to share. Rapidashes could be territorial when it came to mates. But Aideen was gazing back at her daughter unconcernedly.
Blushing even more, but feeling a strange thrill of excitement, knowing that she was about to be mated for the first time, Paulette did as her mother instructed. She stepped away from Colby, towards the back of her enclosure, and turned around so that her backside was facing him. She lifted up her flaming tail, revealing an extremely swollen, heat-engorged pussy to the human. Paulette whinnied with embarrassment as she felt and heard her pussy winking repeatedly. Droplets of moisture fell to the floor of the stall, creating a small puddle between the young mare's hind legs.
Licking his lips, Colby advanced towards the virgin mare. He imagined that he could almost smell the scent of her heat, as though he was a stallion about to mate her. Just the sight of her exposed to him like this was driving him crazy. He wanted to just grab her flanks and fuck her as hard as he could, like he'd done with Aideen, but right before he grabbed her he stopped. Her pussy just looked too inviting, and he had the urge to give something a try. Colby dropped to his knees, putting his hands on Paulette's rump to brace himself, and leaned in close.
Paulette turned her head curiously, wondering why he wasn't doing what she'd expected, and then she whinnied in surprise as she felt something wonderful and unfamiliar on her rear. She tried to see what the human was doing to her, twisting her neck as far as it could go. Colby had his face pressed against her pussy, and he was licking at her, his tongue pressing in between her lips and into her slick, swollen folds. He suckled at her clit, which continued winking out into his mouth as he ate her.
The flavor of the Ponyta's pussy was unlike anything Colby had ever tasted before. Her slippery fluids coated his tongue, hot and spicy, almost searing his taste buds. He slipped his tongue deep inside her, licking around her slick walls. As he toyed with her pussy, he moved one hand in between her hind legs, where he felt her teats. They were slightly engorged since she was in heat, and he cupped one in his palm, squeezing gently. He heard Paulette neigh softly, and felt her body shudder from the combination of his hand and his mouth. Her vagina twitched around his invading tongue, signaling her increasing pleasure from his attention.
Aideen nickered softly, chuckling.
Aideen teased her, laughing even harder.
Raine seethed silently, thoroughly humiliated, but she was distracted by Colby and Paulette. The human had both of his hands on the youngest mare's pussy, using his thumbs to spread her open. Colby was licking very deeply into her, and her fluids were dripping down his chin. Paulette was panting very hard, her front legs moving apart as she adjusted to keep her balance.
The virgin mare was feeling something very new come over her. Up to now, she'd felt incredible sensations of pleasure in her pussy, like nothing she'd ever felt before, but this was something different. She was shaking very hard, and there was a steady, climbing tingling inside of her that was completely strange. Before Paulette could even begin to deal with it, she whinnied loudly, and then she began to cum for the first time. Colby wrapped his arms around her hind legs, holding her in place so that she wouldn't fall down, smiling as he felt his youngest mare bucking against him. He kept licking at her as she came, encouraging her and drawing out her pleasure as long as he could.
When she felt her body coming back under control, Paulette's heart was racing. She'd never felt anything like that before but...it had felt absolutely incredible! Better than anything she'd ever felt before, and she wanted more. Instead of having been satisfied, her heat seemed to be more intense than ever. She blew out a quiet snort from her nostrils, shaking her head from side to side, her fiery mane scattering small sparks through the air. The Ponyta mare backed up, pushing her rump against Colby insistently.
"Whoa, easy, Paulette!" Colby said, nearly falling back on his rump with the force of the mare's bumping. He stood up, placing a hand on her back to calm her down. He stroked back and forth along her back until she quieted down a little, and he moved to her side to brush her nose. "Calm down, girl. I know what you want. I'm not going anywhere, so just calm down. That's it."
Paulette whinnied, her voice sounding desperate even to Colby's unstudied ears. She felt a sense of urgency, as though nothing would be right again unless he was inside her this instant. But she tried to remain calm as he said, comforted by his words to her.
"Good girl...," Colby praised her, trailing his hand along her side as he returned to his place behind her. "Easy now...Here we go..."
The human placed both of his hands on top of her rump. The Ponyta was exactly the right for him, and in a second he was lined up just perfectly. Breaking the codes of acceptable conduct for the second time in one evening, Colby held onto Paulette as he pushed forward into the mare's virgin pussy. He shivered, moaning quietly. Because she was a lot closer to his size, she was much, much tighter than Aideen had been, and even hotter on his cock.
Paulette whined quietly, feeling a slight pain as the human entered her. While he'd been small compared to a Rapidash stallion, Colby's size was just about right for a Ponyta, enough that she was being stretched by him. But though there was a little pain, Paulette felt overwhelming pleasure on top of it. The underside of his cock dragged along her clit as he pushed into her, sending sharp tingles through her body. When he was all the way inside of her, she took a few breaths, getting used to the feeling.
Colby closed his eyes, exhaling slowly as he reveled in the feeling of being hilted inside the mare, virgin no longer. After a few moments, he felt her pressing back against him insistently. He opened his eyes again and saw her looking over her shoulder at him, her expression telling him _Go ahead, I'm ready._Smiling at her, he patted her rump, and then he starting thrusting in and out of her.
Paulette was neighing very loudly, pushing back against Colby. Her mating instincts were running at full force now, since her pussy didn't know the difference between a human cock and one of her own species. She had a vague idea of the difference, but she didn't care at all. He felt very, very good inside of her, and filled her quite snugly. Every time he thrust deep into her, she felt an overpowering pleasure in her depths, one which spread all through her and penetrated her mind. So this was why her mother looked forward to the stallions' visits so much. _This_was the feeling that the other mares talked about all the time. Paulette lost count of the number of times she came while he fucked her.
As he pounded in and out of Paulette's pussy, Colby kept speeding up until he was rocking her body hard with each inward thrust. His balls were slapping against her clit, while loud, wet sloshing noises filled the stable. The Ponyta mare was like a fountain, and they were creating quite the mess. Colby knew he would have a cleanup job waiting for him, but for now he didn't have any regard for that. He was enjoying himself too much, loving the way that the mare's sex was hugging his cock. He could feel her passage squeezing him as she kept cumming over and over, her pussy practically begging him to join her and fill her up with his human seed.
His fingers tightened their grip on Paulette's flanks as he felt himself about to acquiesce to her body's demands. Colby thought he heard himself call out her name, but he wasn't sure. His brain seemed to shut down for a time, and he thrust deep within the young mare as his cock started to pulse its load inside of her. He held himself still inside of her, letting his balls empty into Paulette's womb. The Ponyta was being very loud, stamping her front hooves on the floor of the stall, and Colby felt heat wash over his face as her flaming tail flared up intensely
Finally Colby gasped, taking a breath for what seemed like the first time since he started cumming inside of the Ponyta. His body felt very weak, and he needed a drink of water. No surprise, considering the number of times he'd orgasmed tonight. He felt his face, and noticed with amusement that his eyebrows seemed to have mostly been singed off. Poor Paulette had cum so hard that she'd lost a little control over her flames, though luckily she hadn't burnt his skin.
The human gradually pulled out of the Ponyta. She hugged his cock the whole way, as though trying to keep him inside as long as possible. Paulette whinnied in disappointment as she felt him leave her, and her sex winked as a mixture of her fluids and his semen drizzled out, dripping down to the floor below her. Colby went up to her front, rubbing her nose and stroking the top of her head for a few minutes until her breathing was back under control. Then he made his way out of her stall, stumbling slightly, and walked over to the faucet from which he filled the mares' water troughs, turning it on so that he could take a long drink.
