Mary was well known by all the law students at the University. While everyone would say it was because she was always willing and able to help find any case or book that anyone could ever need but in truth it was that she was by far the most attractive woman on campus. At just a little over 5 foot her petite form was a perfect hourglass with perky 8F breasts which were then balanced by the most perfect tight little bubble butt anywhere on campus, catching the stares of student and staff alike. Although her form was that of utter perfection she always made a point of trying to dress in a demure and respectable manner while she was at work so as to avoid silly comments from her colleagues (not to mention some of the jealous female students) but there was only so much that could be done to hide her beauty. Her long jet black hair which would normally wave its way down to the small of her back was kept pulled back into a tight bun, and her emerald green almond shaped eyes gazed out through cliché librarian-esque glasses. She always wore a plain white cotton blouse with only the top button undone, with a simple black waistcoat overtop that served to subtly highlight her slim waist and the contrast between that which was above and below and then a plain black knee length skirt. Plain, simple and respectable attire for a librarian. However, when she was working on her own doing the evening till close shift she would wear something a little more fitting to her own tastes, not to mention the tastes of the students. So the blouse was undone further down letting her cleavage push its way into view, the black knee length skirt was replaced with a tight fitting (only just arse length) mini skirt and the back stockings were changed to thigh high fine fishnets with a black lace garter belt with a matching black thong over top. Quite simply she changed from trying somewhat in vain to hide her assets from her colleagues to almost flaunting them to those few dedicated students there late working hard. She knew that some people checked her out but she had always been quite reserved about approaching anyone due to the fear of what would happen if people found out what she did. That didn’t stop her from thinking about what she would do if she did…
The semester was over so there were only a few students around when she worked the late shift on her own. There was one really cute boy 3rd year boy she noticed who was there every evening without fail. He was about 5’8” and looked like he could have been an acrobat with the way he was built. He would always be wearing a well fitted shirt, nice grey suit pants and usually a waistcoat. His mousy brown hair was tousled in a slightly care free way and you could see his chest and arms ever so slightly strain the fabric and buttons on his shirt. His eyes were a deep icy blue and they would always sparkle in such a way that made it look like he was always smiling. While all of this was easily sufficient to have made him the most attractive boy in class he was, however, incredibly shy and it was this that caught Mary’s attention. The first time he came up to the front desk to ask her a question he stammered a little and blushed profusely hardly able to meet her eyes.
“E- E- Excuse me miss, do- do you know where I can find this book,” he almost whispered as he handed her a small slip of paper with a call number on it.
Feeling bad for the poor nervous boy she smiled and took the slip.
“Of course. Follow me” she said as she smiled at him. At the sight of her smile he seemed to soften a little but the red never faded from his cheeks.
She walked out from behind the desk and down corridor with the cute boy behind her. Every now and then she would look over her shoulder and see him staring, mouth slightly agape at her swaying slik covered backside. She led him up the stairs, purposefully swaying just that little bit more as she climbed the remaining flights. When they reached the darkened 4th floor landing she turned her head slightly as saw while he was lit from the lights out the window the silhouette of a growing bulge so easily noticeable under his slack grey suit pants. The lights flickered on as they walked down the aisle between the stacks of shelves. Mary’s mind had faded completely away from what she was meant to be doing as she could get the image of that bulge; it was huge.
Such a shame, she thought, someone so shy and quite with such a big thick cock barely hidden away. She snapped out of here revere when she noticed they were at the end of the aisle, she had walked right past the stack she was meant to be looking for. She spun around quickly and walked right into him.
He blushed and stammered, “I- I- I’m sorry” and went to step to the side to let her past and they bumped into one another again as she stepped the same way. This time she could swear she felt her band brush against the massive piece of meat in his pants as she heard him gasp. She stepped past him and led him back a few stacks until she found the right one. She couldn’t get the thought of his cock out of her mind. She had never seen something as large as it must be and he wasn’t even fully hard… a plan that was so unlike her was developing in the back of her mind. They walked down between the shelves to where the book was.
“It should be just down here” she said as she stopped somewhat abruptly and bent over with her legs straight. Her tight bubble butt poked towards him and she could hear him gasp in the silence of the empty room. She leant back ever so slightly so that her hip brushed his hand, his hand didn’t move away…. She stepped back as though to look at the other end of the shelf and in doing so placed her scarcely covered ass against his thigh. The plan that had been forming far from her conscious mind suddenly made its way forward and she plucked up the courage thinking that it was now or never.
She dropped to her knees and turned around to face him which placed her face right in front of the barely contained goal. She glanced quickly around to check there was no one there, there never was at this time of night and then before he had time to feel nervous she reached up, unzipped his fly and deftly released his cock from its restraint.
It was her turn to gasp as the sheer size and weight of what she was holding in her hand. At least nine inches long and over and inch and a half wide she was in absolute awe at the most beautiful cock she had ever seen. After the moments shocked hesitation she licked her lips and wrapped them around the glistening warm thick head. She could feel it throbbing in her hands and hear his breathing escalating as she slowly licked her way around the tip of his cock savouring the taste as she tried to comprehend how she was going to suck such a beast. Slowly but surely she licked and suck her way down his length as far as she could. It wasn’t a gag reflex problem at all; the real issue was that her throat just wasn’t that big.
He steadied himself with his hands on the shelves beside him and his body shuddered from the sensation of such a warm wet skilful mouth engulfed his cock. His body was tingling all over and his mind had completely failed come to terms with what was going on and as such just went blank leaving the pleasure of Mary’s passionate cock sucking. Mary reached up with one hand and unbuckled his belt, unbuttoned his pants and reached inside to play with his balls. The heavy balls were just as shockingly large as the cock in her mouth and felt so soft and warm in her hand. As pre-cum oozed from his cock and it he thrusted slightly back and forward Mary found herself unable to contain her excitement at what she was doing and took her other hand from his cock and hiked up her skirt with an aim to try and release some of the overwhelming pressure that was building inside her.
She ripped her tiny thong aside and discovered just how turned on she was. He clit had swollen to the size of a peanut and her pussy was so wet she could feel her sweet juices running slowly down the inside of her thighs. She had never been this wet in her life and her slick fingers played furiously with her clit. It was too much she needed release straight away otherwise she couldn’t focus on the gorgeous dick that was throbbing in her mouth to the extent that it deserved. She took her other hand from his balls and felt a slight sag in his posture that seemed to indicate that he was close and that if she has just kept going… she felt terrible but she needed it too bad. With one hand flying over her hard clit she reached behind her with the other and felt her tight little rosebud already slick with the nectar flowing from her pussy. At the touch of her fingers her ass relaxed, hungrily wanting something inside. As she slipped two fingers so surprisingly easily into her normally overly tight arse she couldn’t help but moan deeply on his cock as it pushed at the back of her throat.
Mary looked up into his eyes as she fucked her face on his cock and stuffed her arse with her fingers. The look of wonder, lust and such utter desire in his eyes was all she could take. She came moaning hard, forcing both the cock and her fingers as deep as she could as the waves of ecstasy flowed over her body again and again. As her juices flooded from her pussy she slowly regained control of her faculties and returned focus to the task at hand. Thinking that she owed him for her moment of self indulgence she returned her hands to his cock and balls now slick with her juices. With her hand on his cock she fed herself as much as she could forcing her way further down wanting to get it all inside her throat. With her pussy slick hand she slipped her fingers behind his balls and teased his tight arse. He gasped and bucked and moaned as she gently slipped a finger inside him. His breathing was ragged and his heart pounding as he came closer and closer to the point of no return but when he was just about to come Mary would let him slip from her throat and her fingers from inside him to stop him from cuming just yet. She did this again and again and he was sweating starting to beg her in gasped whispers to let him cum
With a wicked grin she impaled her throat completely and slipped a second finger into his welcoming butt and started playing with his prostate. It was all too much for him, he couldn’t take it anymore and this time she let the dam burst and the roaring sensation soared through him as he came squirting jet after jet of thick, warm, sweet cum into Mary’s welcoming mouth. His hands gripped the shelves so hard that his knuckles turned white as he struggled to keep himself from falling to the floor after his legs had seemed to lose all strength. Inaudible to anyone but any librarian there was a high pitched muffled gasp followed by a serious of ecstatic, obviously orgasmic, moans from somewhere in the surrounding shelves. Mary’s eyes flew open. Someone else was there…but they hadn’t confronted them…instead they, a girl by the sounds of it, had just made themselves come. It would have to wait for now however, something had to be done…but what?
She kept on sucking until he was completely dry and the sensation was too much for him. As she slipped her finger from inside him, she licked her lips catching the last of the cum that had escaped from her mouth. She licked their juices from her hands and then dried them with a tissue from her pockets. Diligently she placed his slowly softening cock back inside his underwear with his cock head covered by his foreskin again, did his pants back up and buckled his belt. She grabbed the book off the shelf and held it out in front of her. She smiled a wide warm devilishly loving smile. She was content.
He, however, was still in shock. Mouth wide open, eyes glazed over and half shut in post orgasmic bliss he was taking a little time to make his way back to the fully conscious world. Once he had regained some composure he took the book from Mary’s hand blushing furiously as he fully realised what had just happened.
“What’s your name”? Mary asked still grinning like the Cheshire cat.
“Um its Simon miss,” he replied meekly
“Well Simon if there is anything else I can help you with never hesitate to ask” she said as she winked at him.
With that she turned around and walked quietly down the shelves and along the aisle to the landing. As she looked over the banister of the stairs she saw a blonde haired girl looking up from the bottom floor. Dressed in a poofy pink miniskirt and tight white blouse and with cleavage rivalling Mary’s she gazed up at Mary and blatantly bit her lip before turning and running off.
As Mary walked slowly down the stairs the true weight of what had just occurred started to dawn on her. She had just fucked herself while she sucked a student off and another student watched, not what one expects on late on a Tuesday night. Whatever else happens she must find who that girl was and make sure she doesn’t tell anyone…
