He started early. He'd requested that she have a full bladder before hand, and as she answered the door in her robe she confirmed that this was the case.
As they moved up towards the bedroom she shed her robe on the stair, her naked back and swinging hips framed by the black suspender belt, stockings and heels drew him irresistibly onwards and upwards. His cock was already straining against his trousers.
She'd given the impression of being a bit bored as he'd arrived this time. Oh well, what he had arranged would change all that.
She spun around at the foot of the bed, smiling, one foot in front of the other, her pussy partially hidden, only the trimmed strip on show. He smiled back and sat himself in the high backed leather upholstered chair opposite. Still wordlessly she settled back on the bed, arranged the pillows behind her as support and held his gaze. Slowly she parted her legs and after delicately wetting her index and middle finger she started to slowly work on her cunt lips. Soon, apparently almost despite herself, she was clearly getting wet. The fingers worked onto her clit and then inside, quickly speeding up, dragging her juices from inside and spreading them over her lips and clit. She knew what he liked, and in truth she enjoyed it too. Her eyes closed and she bit her lip,her back started to arch her breathing getting louder and more ragged, catching in her throat every now and then as her climax got bigger and closer. As usual she indicated when she was close to coming, and as usual he stopped her just short. Over the next ten minutes she repeated this twice the second time surprising herself how close she actually did get. By now her full bladder was getting uncomfortable and she told him. This seemed to please him and he indicated that they were going outside. She put on her short jacket, barely enough to cover her arse cheeks and they made their way to the front door. Her cunt was throbbing from the frustration and strangely excited from the full bladder at the same time.
Once in the car he made her open the jacket and spread her legs. Strapped into the seat, the seatbelt cold between her breasts and pressing across her lower stomach, she continued to work on her clit as best she could, keeping herself close to coming, excited in turn by the close proximity of people passing by and the growing ache in her bladder. She was thoroughly aroused by now, her fingers slick and silky, making little wet noises as they moved. She slowed down, keeping just below the brink of orgasm.
Soon the car swung into the University car park and pulled up under a tree near a side entrance. She zipped her jacket up again, clearly they were getting out. He jumped out quickly and moved round to open her door. She got out with a little difficulty, the urge in her bladder now really strong. They walked to the swing doors and moved into the building. There was a long corridor, dark and lit from the far end. the shiny hard floor echoed at the impact of her heels. A couple of female students came the other way giving her the once over noticing her short jacket and stocking tops, giggling a little as they passed.
Eventually he led her to a double door and opened it ushering her inside. they moved into a small waiting room with walls on three sides and a curtain across the fourth. As they stood, a female voice came from behind the curtain. "Come through," it commanded. He lifted the curtain to let her through.
On the other side of the curtain was a larger brightly lit room with an examination table in the centre. At one end of the table were leg supports. "Onto the table please, legs in the supports." The voice came from a little annex room. She hesitated for a moment then got up on the table, swivelling on her bum and slotting her legs into the supports. Her knees were raised and spread. the table was raised under her back and shoulders affording her a good view of the top of her own mound.
"masturbate again please, I need you as close as possible to orgasm." She hesitated again but soon did as she was told, at least it took her mind off her bladder. Soon again she had her eyes closed and got back to that familiar place, in fact she was almost over the edge when the voice came back, just by her head " O.K. stop now please."
She jerked her eyes open in surprise to see the female figure next to her. The voice belonged to an attractive woman. Dark hair tied up neatly, glasses and a clip board. She was wearing a white coat open at the front and clearly showing a sheer white lace bra and high, sheer white lace panties. below these were the straight lines of the tops of white holdups, heels clicked on the floor when she moved. The woman put down the clipboard and picked up a speculum, quickly lubricating the end. "Relax please" was all she said as she moved between the leg supports. She indicated the girl's cunt "Pull your lips open please." Fascinated and a little horrified she obeyed. The woman inserted the nose of the speculum and slid it fully home. It was cold and made her gasp. The woman started to click it open from side to side. soon she was opened further than she had ever been , the cold air and exposure surprisingly arousing. "Masturbate again please." Without hesitation she worked on her clit but she was already nearly there her cunt walls pulsing, juices sliding out from the open base of her tightly spread pussy. She had to stop quickly to avoid going too far.
The Woman pulled up a low stool and sat between her legs, face level with her dribbling cunt she took out a tube of lubricant and put a little on one finger. she reached forward and rubbed the lubricant onto the girl's urethra as it hung down between the open arms of the speculum. The girl gasped at the cold touch and the pressure in her bladder forced a few drops out. She moaned a little at the effort of stopping the stream. The woman opened a drawer in the table and brought out a long sealed packet. She tore open the end and withdrew a long thin flexible orange tube. She quickly lubricated one end and moved it up to the girl's waiting urethra. The girl's eyes widened and she gasped a little as she saw what was happening. The tube slid easily in for the first inch or so, then the woman stopped and checked that the cap was firmly on the other end before she slowly slid it in the remaining couple of inches. The girl winced and twitched a little as it finally entered her bladder. The woman stood up, leaning forward studying the wide open cunt and filled urethra, as she did so her coat opened further affording the girl an arousing view of her breasts through the sheer bra nipples dark and hard, and the shadow at her crotch.
"Try to pee," the girl tried but now as hard as she pushed only a tiny drip formed around the catheter where it disappeared inside her.
"Masturbate," she started, but had to stop almost immediately for fear of climaxing. The woman spent a moment making a few notes on the clip board, then slid a deep metal tray out from under the table. She placed it under the end of the catheter and undid the cap. Immediately the girl's bladder started draining in a noisy strong stream, rattling into the metal tray. The relief was immense, almost an orgasm on it's own. eventually the woman spoke.
"Try to stop it," again try as she might the girl had no control. The stream seemed to go on for a very long time draining her completely, finally it slowed to a final few drops.
"Masturbate."
