Kerry nodded, smiling back at Anson, though it was tentative. "Please…it feels okay, now," she admitted. She pushed back more against the horse, letting out a pained Ow' as she tried to take too much.
"Easy, pup. You've got all I can fit in you. About five inches. Nearly half my cock." He smiled widely, leaning over Kerry and hugging her gently. "Good girl. You're doing great." He pulled back, placed his hands on her hips and started to fuck her with a bit more effort, thrusting slowly but firmly into her stretched, but slightly loosened cunny, going as deep as he could without hurting her.
She was definitely enjoying being fucked now. Her tail swished to and fro, brushing over Anson's shirt, leaving stray brown and white hairs over it, while she rocked back and forth, her head tilted back in pleasure.
The next couple of minutes were full of pleasurable grunting, moaning and murring as Anson mated with Kerry, ploughing her small pussy with his thick equine cock. Now and then he hit her tiny cervix, causing her to gasp in pain, but he apologised and continued to pump her, until he was on the verge of climax. She was starting to pant hard, as if she'd been running. "Come for me, Kerry…show me what a little pup's climax is like," he whispered.
The pup didn't waste much time before reaching her peak. She panted hard, clenching her eyes shut as her small frame shook through her first orgasm. Small yipping sounds escaped her muzzle as she came, and her pussy went into strong, erratic spasms which massaged Anson's cock.
"Ohhhh, yeah! That's it, pup! Milk my cock!" the horse muttered, picking up the pace again. The contractions of her pussy around his shaft felt amazing, and it was just a few seconds later that he threw back his head and whinnied as he began to blast his seed into his young partner. Almost immediately the white spunk began to leak out around Anson's cock, dribbling down to drip onto the floor.
Kerry's eyes opened wide when the first squirt of horse cum fired into her. She could almost liken it to being sprayed with a hose, but inside her. Successive spurts increased the pressure inside her pussy, until she was squirming in discomfort. "Anson…take it out, please?"
The horse was already about to do so, feeling the same pressure from a different perspective. He pulled back, grabbing his cock and aiming up to let the rest of his cum splatter over the pup's back. "Aaaaah," he groaned, watching his thick cum jetting out in several volleys, forming a series of random squiggles upon Kerry's back.
Once their respective climaxes had passed, Anson gathered the tired, well-fucked pup into his arms and gave her a gentle, cum-sticky hug. "All done, pup. Was that okay for you?" he asked, stroking a hand over her head and scritching her ears.
"Yeah…it was good," Kerry replied after some thought. "But now I have this…stuff all over me. And coming out of me." She gestured at the jizz lying in small puddles on the floor, and between her legs. Her pussy felt really empty now, and she was feeling somewhat light-headed.
"Hmm. I forgot about that." Anson pondered what to do for clean up. "I'll clean the mess up on the floor. You…uh…jeez. Um, take off your shirt – that'll need some soap and water to wash the cum and the smell out. Just tell your mother that you got paint on it or something and that you had wash it out immediately." He let Kerry go and slowly got to his feet, wincing as his knees complained about being on the tiles for so long, then went into one of the stalls to fetch a large amount of toilet paper, after doing up his pants to avoid tripping over.
Kerry nodded and stood up, almost slipping in the cum puddles. She wiggled out of her shirt, then dumped it into one of the small basins. A generous amount of soap was squirted out of the dispenser on top of it, then she turned on the water, beginning the process of cum removal. "What is that stuff?" she asked as she worked to was the strange ammoniac smell out of her shirt.
"Semen," Anson replied, stepping out of the stall. "Or cum, as it's usually called." He crouched down, balling up some of the paper, and started wiping up as much as he could. "It's the stuff that makes babies." After a moment he added, "You're too young for that, thank goodness." He turned and fired his first ball of paper into a stall, managing to get it into the toilet bowl. "He shoots, he scores!" Then he balled up some more paper and continued.
The clean-up went surprisingly quickly. In just a few minutes the floor was (almost) wiped clean, though the smell of cum was still fairly strong, and Kerry's shirt was rinsed clean, and smelling mostly of industrial-grade soap. "That should do; hopefully the cleaners won't notice anything. Oh! Almost forgot!" Anson pointed at Kerry's crotch, which still had cum dripping from it. "You'd better wipe yourself clean too. Jeez, and a bath when you get home; wash all that cum out of you."
