Becky stared up at the ceiling, desperately trying to maintain some kind of control, she breathed in small shallow gasps through her mouth, her hands gripped the sides of the chair..a swirl of thoughts and primal feelings competing in her mind. “I can’t cum, I mustn’t cum..I can’t stop it...its going to happen...this is wrong..I shouldnt be naked, he shouldnt be doing this..God it feels so good” Becky's embarrassment, the humiliation, all seemed to just heighten the intensity she was now feeling between her legs, which by now were trembling uncontrollably. An involuntary spasm brought her knees inward toward each other but the doctors hands parted them again. “Keep them apart Rebecca, try to relax” his fingers were now parting her labia, his thumbs spreading her wider. “Some remnants of hymen tissue still visible... I’m going to make you orgasm Rebecca, I know that it may be embarrassing for you, but it’s important I observe your full sexual function”. Becky heard a low buzzing sound...something cold and smooth was now placed on her clitoris and it throbbed with a slow but strong vibration. Becky could feel juices trickling from her...”You’re doing really well Rebecca, I’m seeing some small contractions, give in to it now”

Becky no longer had any choice, the throbbing on her clit, the fingers spreading her open...her hips bucked again and this time she couldn’t stop herself as she went over the edge into a shuddering orgasm, every muscle convulsing..”Oh God..fuckk..no , doctor!”

“Good girl Rebecca, let it happen....6, 7, 8...strong contractions now”

Becky’s arched back slumped back in the chair. The throbbing thing on her clit had been removed and Doctor Graham was arranging some unseen instruments on the tray at the foot of the chair with quite a noisy metallic rattle. Still shaking she tried to catch her breath.

Dr Grahams hands pressed her inner thighs apart again, “Try to keep your legs spread nice and wide for me Rebecca..I dont want to have to restrain you. I’m going to have a feel inside now.” Becky looked down at the doctor now standing between her legs, applying some gel to his gloved fingers, his eyes fixed on her exposed vulva, an almost menacing smirk crossed his face...there was a noticeable bulge in his trousers....she knew this examination was only going to get worse, but she also knew she was going to let Dr Graham do anything he wanted to her. In her limited sexual experience she had never felt quite as aroused as she did right now, her naked teenage body on an examination couch and totally exposed to this perverted old doctors every whim.

His hand pressed her abdomen firmly..then with his other hand his fingers were parting her folds again and two thick fingers slid slowly inside her tight vagina, curving upward, then pushing deeper as he pressed down on her belly. His fingers felt huge inside her, twisting and probing her soft inner walls. His fingers briefly massaged her g-spot before pressing deeply into her finding her cervix.

“Any discomfort here?”

Becky felt uncomfortably full and the pressure of the doctors fingers against her cervix as her abdomen was so firmly pressed down was almost painful..but she tried to be brave

“No...not really.. “

“Thats good Rebecca, just try to relax” The doctors hand on her belly now moved lower and covered her little pubic strip..his thumb seemed to rest purposely on her clitoral hood as his fingers moved inside her and began slowly pumping in and out.

“How are your breasts feeling now?”

“Umm..a little sore still” Becky replied, slightly surprised by the enquiry

“Go ahead and touch them, I want to observe ”

Becky moved her hands to her chest nervously and touched her tender areolas.

“Good girl Rebecca, pinch them, show me “

“what the hell! He wants me to play with my tits while he’s fingering me? Oh my god”

Becky felt like she was being directed in some cheap porn film as she cupped both breasts , unable to contain a gasping moan as the stimulation between her legs continued.

“You’re producing a good healthy amount of natural lubrication now, I’d like to see you orgasm again while feeling your internal muscles and monitoring your heart rate , I’m going to use the stimulator probe on your clitoris again.

This time Becky looked down and saw the shining steel probe, about 6 inches long with a wide, bulbous, pointed head. It looked like a very clinical penis. She watched Dr Graham attach a cable to the base and slowly lower the tip onto her clit, carefully parting her labia and positioning it very precisely.

“Hold the probe there for me now Rebecca, while I hook you up to the monitor”

Becky reached down and held the cold steel shaft as instructed feeling the smooth surface against her clit.

Dr Graham was peeling the backings from some adhesive pads, then placing them on Beckys chest, one above each breast, one in the middle between them, one under her left breast, then two slightly smaller ones just under each nipple, slightly overlapping her areolas...he attached cables to all of them and then switched on the monitor ...”Good...Good strong heart rate...now I’m going to start the probe” .

The probe buzzed into life in Beckys hand, the same low, slow, strong vibration as before.

“Guide it to where you feel the most stimulation Rebecca.”

“Oh God, now he’s going to watch me masturbate in his gyno chair”

Becky circled the probe around pressing the “glans” firmly into her clit, she closed her eyes as the intense vibration began to cause a wave of pleasure.

“Now , you’ll feel some different sensations in a moment, just relax and let it happen “ Becky wondered what Dr Graham meant...and then suddenly the electrical pulses just below her nipples began...tingling, sharp little pains..like somebody repeatedly pinching them over and over...they were instantly erect and each one quivered with every pulse of electrical charge . Becky screamed and dropped the probe, her hands gripped the sides of the chair. Dr Graham was back between her spread eagled legs......and he was fastening restraints around her ankles...
