"My friend said you could take care of me." The dog's voice was low, as if he feared being overheard. He looked at the vixen haltingly, pink eyes stealing bite-sized peeks of her. A part of him was hoping she'd say no - then he could back out of this and head home basically no worse for wear.

The vixen shrugged, but a smirk played at her face. She was no older than twelve, Pink thought. He himself was thirteen. His friend said she gave the girlfriend experience, and that she was hot, confidential, and cheap. Pink had twenty dollars in his pocket for her.

"Anal's fifty," the fox said. She smacked her lips. Pink realized she had chewing gum in her mouth; the smell of spearmint wafted on her breath. "I'll suck your dick for twenty. Cum in my hair and I'll tear your nuts off."

The dog - Border Collie, not something people tended to guess at first blush - thrust his paws into the pockets of his baggy jeans. "Um. I wanted-, I heard you got a-," he leaned closer, "a spade."

"Oh, pussy," the vixen snorted. "Pussy's thirty."

Pink whined. "I only have twenty..."

She huffed, smacked on her gum. "I'd blow you," she said, "but I ain't wasting my gum."

The dog started to speak. "All right, fine. I'll just go-."

"So you can have some pussy. That's it though. I'm not kissing you or talking dirty, none of that girlfriend shit." She unbuckled her small black belt and lowered the loose-fitting jeans she wore. Down they slid to reveal girlish hips with a hint of curve to them, and more importantly the thick black vulva between her legs. "Doggystyle," she announced, tone accepting no argument. She got down on her knees, then draped herself over the grubby crate she had previously been using as a seat. Whatever markings had been on it were long since worn off. The wall of the adjacent building, some kind of defunct welding shop, had been caked over and over so many times with graffiti that none of the tags were legible.

Pink began to pant just at the sight of the girl's box. On all-fours was the way it was meant to be presented. Its flesh was swollen and dark, pink glinting wet just between the lips. The Border Collie hastily opened his jeans - no belt on him, so he frequently had to hike up his baggy pants - and shoved them down along with his briefs. His penis, knotted and red, already jutted partly from its sheath. Precum dribbled from the tip. As he knelt behind her, he asked shakily, "S-so, what-, what's your-?"

"Name's for guys who aren't broke dorks," the girl said dryly. She reached down to her pants and pulled her phone out of her pocket.

Pink's slide into the vixen was smooth as silk. He trembled as his sheathed knot bumped against her mound. "Ooh-, ooh god," he breathed. This was so unlike masturbation. Jerking off felt good but pussy was indescribable. Although his penis was inside of her, he touched her body tentatively as if handling something expensive he had borrowed from a friend. His paws trembled on her hips. They felt good in his digits, like they were meant to be in his grasp. Then he felt up her belly, feeling nipples - soft, but nipples all the same.

"Can I-, um, t-touch your-, your boobs?" asked Pink, every word struggling to escape his stammering mouth. His cheeks seemed hot like embers. His cock was already throbbing, leaking clear, musky precum into the girl.

"Whatever," the vixen answered. "Hurry up and fuck me, would you? You're wasting my time."

"I'm sorry," Pink blurted, "so sorry."

The dog moved his hips with virginal awkwardness. He felt over her body, her soft young body with its small, growing breasts. Still her nipples were slack, only hardening up as he insistently touched them. But the girl sighed, then murmured, "God dammit."

"Sorry," Pink winced.

"Not you," she said absently. Pink glimpsed her phone; she was playing some puzzle game and had evidently lost.

The Border Collie draped himself over her. At first he tried to hold onto her breasts and fell against her, causing the vixen to hiss. He grimaced, apologized again, and planted his paws on the concrete. Each movement of his hips was a massive effort. She was so tight and perfect and hot inside, his penis gliding on her vaginal walls with blissful ease, but awkwardness made his body gawky and stiff. He reached down and pawed at his penis, pulling his sheath over his knot. That it still stuck to his knot without pulling back naturally embarrassed him greatly. He was thankful that she hadn't seen it, and yet still felt the sting of humiliation knowing it had happened at all with her.

Pink leaned over her. He was shorter than the younger girl - another thing to be nervous about. He thought that he, as the male, should be bigger. He nuzzled with her, licked her cheek. Instead of saying no or even pawing him away, she only pulled away from his attempts to lick and kiss, and then she went back to playing on her phone.

His eyes scanned the text messages she was sending and receiving. One of her friends asked how work was going. Her reply was one of boredom and dissatisfaction; [i]feels like this dumbass is using his finger.[/i]

That was just about it for Pink. He was close despite the painful awkwardness of the situation and the bitchy distance the vixen put between them. He pointedly avoided her phone as he humped her, bumping his knot against her thick, dark muff. His friend had told him the knot went inside - that you had to get it in before you came and it made things feel so much better. It was implied, though not stated, that knotting the girl was crucial. Pink worked his knot against the young prostitute with all the energy he could muster. Pink was a young, vital dog, but he was trembling and afraid, his limbs shaky like jelly, his balls tingling with that all-too-familiar sensation of orgasm.

"I want-, I'm gonna put it-, I'm-!" Pink yipped. He grimaced, huffed, pushed his knot against her. The vixen grumbled, then went silent. She smoothed back her blonde hair and returned to texting her friend.

The Border Collie knew he wasn't supposed to cum this quickly. [i]Premature ejection[/i] or something like that; whatever it was, it was bad. It had never occurred to him that it might happen. When masturbating at home in front of his laptop, he could stretch a session out for an hour if he wanted to. The sheer pleasure of pussy never crossed his mind. He whined and he pushed and he failed to bury his knot inside of her. As he came he nuzzled her and tried to kiss her, but again she simply dodged him. This time, however, she spoke: "Oh, you done? Good."

"Sh-, shit," Pink wheezed, feeling both satisfied and unsatisfied at the same time. He remained against the vixen but stopped trying to push his knot into the spongy, soft lips of her spade. His semen drooled out of her vulva and dribbled to the concrete below in a few long, thin strands. Pink's climax had been a small one.

"Okay, out. Out," the vixen ordered. "And pay up."

"Just-, just gimme a sec," Pink lamely protested. But he was already pulling out of her, knowing it was over. Knowing he had fucked it up. "Was it-, did you like it?" he asked her in a small and diffident voice.

The fox pulled a wad of Kleenex out of her jacket's breast pocket and blotted her creamed vulva until he mess was gone. Pink's entire discharge save a few escaped strands filled less than two wadded-up tissues. "Pay up, twenty bucks," said the vixen, growling. "Don't make me kick your ass."

Pink felt a bit like crying. He had never for a second believed the crap about sex being a special bonding experience, but he felt there should have been more to it than three minutes of clumsy grinding and rebuffed kisses. Avoiding her eyes, Pink stood up and pulled his briefs over his knotted erection, then he buttoned and zipped up. "I'm sorry," he murmured as he passed her the wrinkled twenty.

She tucked the money into her pocket and waved him off. "Cool, now go. Next time you're gonna pay full price."

The dog studied her for a moment. He wanted to ask her again - did she enjoy it, even slightly? When she looked up from her phone, she seemed to regard him as something stuck to her foot. Then she asked, "What? We're done. Go away."

"I-, yes, yeah. I'm sorry," mumbled Pink. He turned and left. When he masturbated that night, he thought about the vixen and how nice her spade had felt.
