It was Sarah's first time nude modelling, she never dreamed she'd be doing something like this. But she needed the money and the pay was very good for just an hours work. Besides, modelling for a bunch of school children, it wasn't like it was pornography or anything.

When she arrived the art teacher turned out to be a bearded overweight man in his fifties who did his best to reassure Sarah. They had all sorts of models coming in for this evening class, men and women, and his students were very professional about it. Sarah nodded in all the right places but she could still feel her heart beating faster at the idea of being naked in front of a group of strangers.

As she walked into the room behind the teacher she was shocked to see that these students were not children as she expected but much older pupils, around 15 or 16, and all boys. She felt panic rising in her but realised she couldn't back out now without really causing a scene. The boys eyes widened on seeing her and she wondered just how many young female models they had seen before.
As the boys set up their easels in a circle around a small raised stage the teacher led Sarah behind a wooden screen so she could undress. With her fingers trembling with nerves she unbuttoned her dress like a robot, trying to put her mind elsewhere and not to think about what she was doing. Behind the screen she still felt some security and she put on the dressing gown that had been left for her. She wondered whether she would somehow be able to pose in such a way to maintain some modesty at least.

But there was little chance of that she realised when she saw the teacher place a wooden chair on the stage for her to sit on. She climbed up realising that the eyes of all of the boys were watching her every move. The teacher nodded for her to remove her robe and closing her eyes Sarah slid the robe down and let it drop to the floor.

There was a silence in the room as she knew the boys were taking in every inch of her body. Sarah knew she was attractive, and she had worked hard to stay in shape as she was going on holiday soon and wanted to look her best on the beach. Her boobs were large, round and heavy, a little saggy but an impressive 36D bra size. Her long blonde hair hung down to the small of her back where her well rounded bottom curved out in a sort of heart shape. Sarah had not thought about it but her perfectly shaved pussy now made her feel even more exposed. Her large pink labia stuck out at the best of times and the silver stud clit piercing now seemed slutty and wrong. 

The teacher cleared his throat and Sarah opened her eyes again to see him motioning her to sit. Knowing she was on display she sat on the chair and crossed her legs, trying to maintain some dignity at least. The boys were still staring at her, eyes wide, some with their mouths hanging open. Sarah realised that most, if not all these boys had never seen a naked woman before except on the internet. Despite the teachers reassurances it was clear now that their usual models were probably male, old men who didn't care anymore and appreciated the chance to earn some easy cash.

Under the direction of the teacher the boys at last began to draw, although they all looked quite nervous. Sarah took some consolation from this and she started to feel a little better. Its only an hour she thought, I can get through this. Then she noticed the teacher walking out, muttering something about catching up on marking and she realised that she was alone now with ten horny boys surrounding her.

Sarah tried her best not to make eye contact with any of the boys in front of her, but every now and then she would glance down and see them staring once again at her breasts, or at where her legs crossed. With some surprise she could also see the bulge in the boys trousers and she realised that many of these art students were getting hard watching her. 

This realisation was exciting, as though after feeling humiliated having to strip in front of them she had regained the power somehow. This feeling that she was in control again gave Sarah the urge to tease them a bit and get her own back. She leaned forward just a little bit more on her chair knowing that this would make her boobs hang down just that little bit more, and those boys behind her would see her ass cheeks spread open just a little wider.

She heard a gasp as she did this and smiled to herself thinking she was in charge of the situation now. But when she glanced down again she saw at least a couple of the boys were now rubbing the front of their trousers, massaging their hard cocks through the material. Sarah had seen men do this before but never so openly, it was almost as if these boys had been placed in the most sexual experience of their lives and were helpless to seek some relief.

And Sarah felt it too, that flood of warmth in her belly reaching to her pussy, making it come alive with sensation. She could feel her own excitement building as she realised that she was educating these boys in more ways than one. With the warm flush of excitement making her pussy throb she uncrossed her legs without thinking, parting her thighs to allow her pussy to breathe.

Sarah looked down at herself and could see her large pink nipples were now sticking out firm and erect. Her pussy was becoming flushed, her labia, fuller, darker, aching for attention. She had ruined their paintings now she realised, having moved completely out of position, but she knew the boys would prefer her in this position and might even complain if she moved back.

Sarah glanced up once again, and this time she did get a shock. Sitting to one side of his easel one of the boys had pulled his cock out and was openly masturbating in front of her. His cock was perhaps average size but very stiff and hard, his hand working up and down the shaft in a well-practised motion that took in the length of his shaft. Sarah gasped and wondered whether she should say something before things got too far, but as she turned her head she saw the other boys were now doing the same. Now that one boy had taken the risk the others were copying his example and around her she saw all ten boys undoing their trousers and taking out their hard young cocks. Some were quite small and others surprisingly big, some dark, some pale, some cut, some uncut. All of them were extremely hard though, pointing skywards and throbbing with excitement at the sight of Sarah's naked body in front of them.

Sarah knew she should have been shocked, appalled, even disgusted at the sight. But the longer this went on without her raising a complaint the more she became a part of what was going on. She had started this and she was extremely flattered that these boys, who were at least ten years younger than her were so aroused by her.  She knew that every one of these boys wanted to fuck her, although they probably had no idea how to please her, but that lust was such a turn on that she could no longer stop this.

Sarah felt her hands rise up to cup her boobs, lifting them up as she pinched her nipples between thumb and forefinger. Wetting her fingers with her tongue she teased her nipples, tugging on them and pinching them until they were hard like bullets. Her hands then slowly slid their way over her smooth belly, down between her legs. Spreading her thighs even wider she knew her pussy was now completely exposed, and as she parted her labia with her fingers she saw the sticky wet strands between her lips that betrayed her excitement. Her clit was stiff and aching now as her wet fingers rubbed against the silver stud, making it stick out further than ever. Then with the palm of her hand pressed against her clit she slid her fingers slowly inside her cunt.

A quick glance up and she could see the boys stroking their cocks even faster now. Their eyes were fixed on her with no thought as to where they were or who else might be in the room. Sarah smiled as she watched them, making eye contact with each in turn as she continued to slide her fingers slowly in and out of her aching wet cunt. Behind her she heard one of the boys moan as he started to cum and Sarah deliberately leaned forward over the chair so he could see her cunt and asshole exposed from behind. Reaching behind and sliding her hands over her smooth round ass cheeks she spread them wide as the tips of her fingers brushed lightly over her tight little asshole.

She could see them starting to cum now, one by one their cocks spurting white creamy ejaculate over their hands and onto the floor. Some of them were really quite impressive, the jet of cum landing on the stage near to her feet. Sarah put one foot up on the chair and started to finger herself faster and more frantically. As the boys shot their cum at her she worked her fingers in and out of her cunt faster and faster, feeling the inner walls of her pussy tighten around them. Moaning loudly, oblivious to where she was or who was still watching she started to cum against her hand, her body arching as her cunt tightened up one last time. Waves of pleasure flooded through her body as Sarah slowly, tremblingly relaxed and slid her wet fingers out from inside her.

Around her the room had gone silent again. The boys were staring amazed at her, their limp cocks hanging from their trousers, some dribbling white sticky cum from their ends. Sarah felt herself regaining her composure and as she realised once again where she was she straightened up quickly, sitting up straight and cross legged once again. The boys, following her lead quickly copied her example and tucked themselves away, making an embarrassed effort to clean up the cum that was now splattered over their clothes and the floor around them.

Just at that moment the door opened again and the boys teacher walked back in, his head buried in some papers. Completely oblivious to his red faced pupils he sat down at his desk and continued his marking as Sarah breathed a sigh of relief that somehow he had not noticed anything amiss. With a concerted effort the boys returned to their work. They were no longer able to make eye contact with Sarah but she caught them exchanging knowing grins with each other. When the session finally came to an end Sarah dressed quietly and the teacher thanked her for her time. When he asked whether she would be willing to do this again she did not hesitate to accept loudly and confidently so all of her boys would hear.
