Julia was captain of the School Netball First XI. Six feet tall with high but full breasts which she mischievously never constricted with a bra for their games, with the aim of distracting the opposition, and short, bobbed hair which gave emphasis to her fine cheekbones and large mouth. Her Fellatio teacher had frequently reported that this big, full-lipped mouth was at once a blessing and a curse: her technique never got any practice as men would ejaculate almost as soon as they saw those lips closing around their cock-heads. Whilst she was excellent at "sperm play" therefore - swirling the creamy semen around her mouth and tongue as it belched from the glans, her tongue-swirling techniques had been little tried. But the wobbly bouncing breasts were definitely an advantage - at the very least they kept the fathers who had turned out to watch their daughters play happy. They loved watching her prominent nipples worrying the faces of shorter opposing players as Jane attacked the goal in a leggy flurry of pleated skirt and arse-stretched white knickers, and would sort the image away for later use. The lonely divorcees would fill crushed Kleenex on their beds, surrounded by lurid photographs dismissed for a moment as the image of the big girl returned to them. The luckier ones might have their wives remind them of it as their wet vaginas hurried them to orgasm: "What about that big blonde bitch of a netball player? Imagine splattering those tits! Or sticking it up between her arse cheeks. Or I could suck on her fat clit, as you came all over that mouth of hers..." And their cervixes would always be filled with spunk at this image.

But there were no fathers present at the moment. This was just a lunch time practice, and as she watched her team disperse back to the changing rooms, there were just two things on her mind: first, that she must try to improve her goal attack, and second, that she badly needed a piss. The two were not unconnected; efficient goal attack demanded a strong, scissor-like action from the thighs, and had she tried that in her current state, she would have splattered the playground and probably some of her team-mates' white-socked ankles with the resulting golden jet that would have been forced through her gusset.

So she had played a fairly tame game, her pleated skirt fluttering, her bottom hovering as she hopped from foot to foot, trying to make it seem as if she was readying herself for the tackle, but really just trying to concentrate on keeping her bladder closed. She couldn't clutch her cunt through her skirt, or cross her legs as the younger girls did - she was seventeen years old - but she sometimes wished she could.

Despite the desperation in her belly, however, despite the urgency to get her knickers round her ankles, and her slim, teenage thighs astride the toilet bowl and to hear the relieving splashing noises below her, she paused before entering the changing rooms. The water-fountain was the only source of drinking water, and her coach had always stressed the importance of replacing fluid after training.

Clenching her piss-muscles tightly, she decided that she could wait a few more minutes, and lowered her mouth to the drinking fountain. Any man watching the sight of the stunning tall blonde bending to drink at the fountain could scarcely have failed to be aroused, her fantastically long, smooth legs tautly poised, her short pleated netball skirt fluttering to give glimpses of the curve of her broad arse-cheeks which gripped her flimsy white knickers tightly between. Her unrestrained breasts had fallen forward in her t-shirt, and their pale round undersides were clearly visible to the correctly placed eye. Any man close enough to watch her lips closing over the spigot, her tongue lapping, her throat muscles delicately swallowing, would have been unable to avoid imagining that his own cock was the lucky spout, providing this thirsty teenager with all the sticky semen she could drink, though the more creative onlooker might also have seen her valiantly trying to cope with an eruption of piss from the spread labia of a girlfriend. Certainly piss was closer in her mind, as not only did she have a gallon or so waiting in her gorgeous belly, but this afternoon, she suddenly remembered was the final rehearsal for the piss pageant. But that meant....!

She suddenly jerked her head up, like an elegant gazelle hearing a twig snapped by an unstealthy cheetah. Indeed there was something of the elegant animal in the urgent gallop to the changing room door, except that in her haste she forgot her control for an instant, and a thimbleful of golden juice escaped from under her knickers and traced a long wet trail down her leg to her ankle, drying as she ran.

Heedless of this, she burst into the changing room just in time to see: TOILETS LOCKED FROM 1PM IN PREPARATION FOR PAGEANT. The notice was in red letters and looked pretty insistent, still swinging from the toilet door where it had just been pinned, almost as insistent as the big, broad brunette who stood nearby jangling what were obviously the keys to the toilet.

"Ohhhhh, no!" declared Julia, petulantly stamping her foot, before quickly wrapping her left knee over her right, and standing awkwardly pressing her fist into her groin. All of the other girls in the team, stopped their changing, and watched their captain's predicament. They had all had a chance to use the loo before it had been locked, and were now either peeling off their knickers to use the shower or had emerged, dripping, and were now towelling their teenage bodies down.

"Vanessa, you can't!" protested Julia.

Vanessa was the Games Prefect, and Julia suspected that she had always resented the fact that Julia and not she had been made Captain of Netball. Certainly she was not being terribly accommodating now as she watched Julia's discomfort with an amused shrug.

"It's not ME, " she replied. "You heard the announcement like everyone else, didn't you? Or were you late that morning? Miss Stebbings said that she was fed up with girls turning up for Piss classes only able to manage a dribble. And with the Pageant so close, she had to insist, and I thought quite reasonably, that ALL the toilets in the school be locked from one o'clock"

Julia winced as she heard this last part, and said: "But you've got the key, Vanessa, SURELY you can let me in for a quick wee?"

Vanessa gestured towards the girls. "How can I do that, with the younger ones watching me? Rules are rules, Julia - I've got to set them a good example, you see?" She simpered, and Julia wanted to kill her. She was urgently trying to think of what she could do. She could try to climb over the walls of the cubicle, but there was no way that Vanessa would let her do that, and she showed no sign of leaving. In any case, she would almost certainly lose the lot if she lost her footing for a moment. There was the wash hand basin, but she couldn't bear the shame of doing it in there, and it was against the rules, as was pissing in the shower. What could she do, what could she do?

Vanessa's face softened. "Poor Julia. Are you absolutely desperate?"

"Yes," pleaded Julia, pathetically.

"ABSOLUTELY desperate?"

Julia nodded again. Maybe she would take pity on her yet. Vanessa put a friendly arm around her shoulders. "It's terrible having such a full bladder, isn't it?" she whispered, mischievously. "All that piss stretching your belly. All that fizzy lemonade you drank at lunch-time, all that cool water you drank at the fountain..."

"VANESSA!" Julia pulled away angrily, as Vanessa chuckled a dirty laugh; a thick cream of sadistic arousal was forming between her cunt-lips as she considered Julia's plight.

"I expect you can hardly wait to get astride a toilet to let it all out, can you, Julia? Imagine it gushing out from you, trickling and tinkling...."

"Oh, GOD!" said Julia, and in a second, before Vanessa or anyone else could stop her, she was at the sink, her trainer hooked over the taps, the long smoothly-waxed thigh of her other leg tautly balancing her as she struggled to attend to her soaking, spluttering white gusset, now turned yellow with the piss dribbling out despite her best efforts. The younger girls watched with a mixture of disgust and fascination as their heroine, the Captain of the Netball team, suffered the humiliation of having to piss in the sink, but Vanessa was pressing her fingers through her skirt against her mound in a way which suggested that she too needed a wee: in fact, it was a surreptitious wank, which became more obvious as soon as Julia managed to get her gusset pulled aside, and her swollen pink labia were revealed, flapping back and forth in the powerful, roaring jet of sparkling golden piss which squirted from between them and went gurgling down the plug-hole. Vanessa's true feelings were revealed as she sank to her knees next to Julia, her eyes level with Julia's spasming cunt, a slim finger frothing in her own knickered furrow, teasing her towards the massive orgasm which Julia's predicament was about to induce. For her part, tears of mixed shame and relief were running down her cheeks as the forceful jet continued to squirt from her hairy pussy, tears like the droplets of gold which dripped from her flaring buttocks onto the white porcelain, and the resentment and hatred she felt for Vanessa welled up inside her as she saw her masturbating. The bitch had humiliated her for her own sexual thrills!

Now Julia was good girl: she held doors open for teachers, she did her homework on time, and (unless it was forbidden for a homework assignment) she always wore fresh knickers every day. She wasn't prone to vindictiveness or nastiness and had a forgiving nature. But when she saw Vanessa's lustful face poised there by the rim of the basin, leching at her poor exposed cunt parts, the temptation was too much.

A simple change of the angle of her hips sent her piss shooting in a big fountain up, out of the basin, in a huge golden arc, where it squirted straight into Vanessa's vixenish face. To Julia's astonishment however, the large-breasted brunette bitch just stuck out her tongue, as if Julia had a big cock which was just about to launch a big ejaculation of spunk onto it. Julia saw from her face that she was coming.

"Oh, yes, all over me, do it all over me!" she gasped, and before Julia knew what she was doing, she was standing over Vanessa swirling her hips to splatter the brunette's big wobbly tits, making her nipples stand out through the transparent white cotton, and finally squirting all over the girl's clitoris, wanking her own as she did so, so that they came together, Julia slumping down on top of Vanessa, her sodden snatch squelching over the stark soaking nipples of Vanessa’s breasts, ejecting the last few spurts of her piss in time with the dying convulsions of her fantastic orgasm.
