''Nurse can you help Angel lay back?''

The nurse helped Angela move until she was lying on her back with her legs out straight leaving her looking up at the illuminated ceiling.

''I will now continue with an examination of abdomen.''

Angela felt the doctor's hands move down and occasionally pressing into her whilst asking ''any pain here or here'' in very much the same way as her previous examinations. As he neared her pubic area he moved the folded gown lower and would have exposed some of her pubic hair if she hadn't shaved all but her 'landing strip'.

''All seems fine there Angela so we'll proceed to the internal examination. Nurse can you remove Angela's panties again now?''

Angela felt her heart start to pound in her chest and if she wasn't already flushed with embarrassment before she certainly would have shown the whole room she was now.

The nurse came beside her and asked her to raise her bottom and again. She instinctively did as she was bid and felt the nurse start to pull the waistband of her panties down. Then she heard the headmasters voice.

''Here let me help'' And as the panties came free of her bottom the headmaster lifted her legs by her ankles and at the same time the nurse removed the gown completely, pulled the panties all the way down and allowed the headmaster to finally take them off.

Less than an hour ago she was just another teacher with all her modesty intact now she lay completely naked in front of two previous students and had had the headmaster remove and take away her panties - surely he'd planned this! She felt utterly humiliated how could she ever go back into the school after this.

''Time for the stirrups now please nurse.'' Within seconds the stirrups where in place thanks to the new efficient couch's design. The nurse lifted her right ankle and placed her foot in the stirrup on that side and the headmaster did the same to left. Leaving Angela to believe that the headmaster had seen this before and knew exactly what to do.

Angela felt sure she heard a whispered voice say. ''I told you a natural blond.'' It could only have been Tony she thought, he must be really enjoying my humiliating exposure.

There followed a soft whirring sound and she felt the couch start to raise up and at the same time tip at a slight angle leaving her head slightly lower than her hips. Also she could see a light lower from the ceiling just above where her hips where. She felt Velcro straps being fastened around each ankle and her wrists holding her arms down onto the couch by her sides leaving her totally trapped and immobile.

Another whirring noise and the stirrups began to move spreading her raised legs. ''Comfortable Angela?'' Said the doctor but Angela felt herself unable to answer.

She knew now she was spread for all to see and was aware of all the eyes on her as she felt another movement beneath her bottom as a section of the couch folded down to allow more access to her formerly most private areas.

''Right gather round everybody so you can all see'' Said the doctor.

She could see and feel the movement as the five heads moved in to view her now naked and exposed body under the bright light from above.

''I'll explain for the benefit of those not familiar with female anatomy and probably includes you Trudy, what the female genitalia consists of and he started to touch and name each part to his willing audience.'' He touched and named her labia majora and minor, clitoral hood and clitoris, vaginal opening, perineum and final ''I'm sure you all know this the anus.''

OMG I'm lying, spread naked and being used like a diagram.

''Right let's see what you've learnt, Trudy can you show me Angela's labia minora.''

''It's there doctor.''

''No you need to show me Trudy don't be shy Angela has consented to be our model today.''

No I didn't, I was tricked she felt like shouting out. Then felt her sex being touched and her outer lips being spread.

''There doctor''

''Yes good. Now Tony can you show me the clitoris.''

Angela gave a restrained jump against her fastening as a finger touched and tweaked her clitoris. ''Not so quick Tony, that's very sensitive, a pleasant sensation for a woman during sex but be a bit gentle when touching in an examination situation like this. Anyway well done both of you. Any questions?''

''Is that an unusual amount of fluid in the patient doctor?'' Asked the headmaster much to Angela's horror.

''No as I said before patients often show a little discharge of the natural vaginal fluid during examinations, in fact the lubrication helps just as it does during sexual intercourse to make penetration more comfortable during the examination for them as I'm sure it will in this case. Now Angela I'm going to start your internal examination so try to relax and it will make it more comfortable for you.''

Angela realised to her utter horror that she was getting turned on being exposed like this and knowing that she and her 'sex' were the centre of everybody's attention. This morning if you told her she would be gradually stripped naked and bound like this onto an examination couch in front of former students and her headmaster she have never believed it. But some inner need was being fulfilled.

The doctor moved between her legs again and she heard the snap of fresh gloves then fingers spread her and a finger began to explore inside her while the doctor gave his next lecture to his eager audience. Angela as she felt his intrusion into her couldn't help herself trying to raise up to meet his fingers. One inside her and a hand on her outside above her ovaries as he explained to the room.

Then to her horror she realised that next he might conduct a bi-manual. They would see him push a finger into her anus something not even a boyfriend had ever done. She realised that was why the end of the couch had dropped away earlier leaving her bottom exposed over the end of the couch. And it did happen. ''I'm going to do a bi-manual examination now can you all see clearly, I'll just change my gloves again.''

''Not really.'' that was Tony's voice.

'' I'll tip the couch a little higher, is that better?''

'' Yes doctor came two or three voices.'' Angela felt as if her 'sex' was being raised and exhibited almost like an offering to the god of male lust. She feared she have slid off the couch if she hadn't been restrained.''

A finger entered her anus as she followed the instruction to bear down on it. It felt uncomfortable at first but no more, then a finger from the other hand entered her vagina again both exploring her like in previous gyn exams but always with a female doctor and always in private.

''All done now.'' Trudy would you like to examine the patient now?

What! These two were now to be allowed to invade her body.

''I'll just lower the couch a bit to make it easier for you Trudy. Oh it doesn't seem to be moving, let me check …. no can't see anything stopping it. Nurse can you see if the technician is still here he was servicing the ex-ray this afternoon.''

''I'll go and see doctor.''

Angela almost fainted and any desire she'd previous felt disappeared.
