During the ‘happy hour’ before a dinner party with some friends, Brenda kept staring at my wife’s legs. I always said she had great legs, and my wife does too. That night Sandra wore a royal blue dress with white patterns and an unusually low neckline. It was backless and braless so Sandra had to be careful about bending before people unless she didn’t mind showing them her small tits and dense nipples. It ended a conservative two inches above her knees. The oddest thing about it was that Sandy rarely wore a dress. She preferred her tiny jean shorts which showed off her well toned yet slim and sexy legs.

“Brenda, why are you fixated on my legs tonight? You’ve seen me in shorts and a bikini. What’s so fascinating tonight?”

“True, Sandy. The dress shows less, yet emphasizes your little problem you complained about often enough. Watching your knees rotate in to face each other when you stand. They look perfectly square when you are seated. Don’t you think so, Bob?”

“How would I know, hon? You think I stare at my friend’s wife’s legs?”

“Yes. Of course you do. Have they gotten worse?”

“Not that I can see. Her dress is too long to know for sure. If you want my opinion, Sandy, you’ll have to hike it up a few inches.”

“Nice try. I’ve already been to an Ortho, so I know the problem and I’m not willing to have the ugly surgery it will take to fix it.”

“Oh go on, hon. Show Bob your legs sitting and as you stand.” The others drew closer as they understood the challenge. We’ve all seen Sandy’s sexy legs and are grateful for her daily exercises and jogging. She pouted, then agreed. She stood and hiked her loose skirt up about four inches.

Bob immediately commented, “That’s not enough to tell. I think another three inches will do before you sit.” Sandy looked at me for help. I rotated my index finger to indicate she should raise her skirt. She blushed a little and kept staring at me as she raised it, waiting for a signal to stop. Her knees practically stared at each other. I didn’t plan to stop her as she was responding to a request she’d agreed to honor. That suited her closeted exhibitionism perfectly. As long as she ‘had’ to do anything, including exposing herself, she felt required to follow through. So she kept raising her skirt until her panties began to show.

A tiny smirk said she was pleased with herself for being so daring and compliant. Brenda said, “That’s enough, sweetie. Now sit slow as you can.” As she began to sit, we, those of us watching her knees, saw her knees rotate greatly to a normal position.

As she fell the last inch on the seat, with her skirt nearly at her hips, Bob asked, “Oh, did you forget your panties today or did you plan to flash us?” Sandy’s eye popped. She bent to check her panties and exposed her bare tits to us. Bob smiled as his slacks grew tighter.

Sandy spread her knees to check, then stood and, acting frustrated said, “No, I didn’t forget them. They are tan and I have them on. See?” With that she raised her skirt to her navel to show off her mini panties.

“Thank you, Sandy,” I said. “Now that you gave all the men a hard-on with your camel toe and cute tits, I think it’s Brenda’s turn. She started this, so we should all check her ‘knees’ too.” She did a spit take and refused. “Anyone else want to show us all my wife did? No one? Ok, Sandy. I think you can release your skirt.”

Brenda whispered to us, “Sorry. I didn’t mean for it to go that far. You can see that Bob enjoyed it. I have an Ortho you may like. He’s extremely thorough and will find another solution, if there is one. He’s family so I can get you in and at a minimal price your insurance will handle. I’m sure you’ll like him. He’s skillful and easy on the eyes too.” Sandy considered it for a moment and decided there was no reason not to get another opinion.

Two days later, Brenda called to say she convinced her family Ortho to see us. It had to be after hours as his schedule was full for months. We agreed to the next Friday at 6:30 P.M...

When we arrived, Dr. Richard was with his last patient and had already sent his staff home. At 6:50, a pretty woman exited the exam room smiling and blushing. “Hello Dr. Richard, Brenda sent us.”

Shaking hands, he said, “Yes, I recall. Brenda is a frequent patient. Let me lock the doors. You can call me Dick, if you like. Go on in there.” We entered the austere exam room. It had a typical exam table, but had split leg boards instead of stirrups. We guessed that made sense. Sandy wore loose shorts and a button down blouse for the exam.

The doctor came in and closed the door out of habit. Brenda had described Sandy’s problem, so he looked at her bent knees closely, then flexed them and rubbed his chin. “Brenda did say I was thorough, right?” We nodded. He took her hand and helped her down. “OK. Take off the shorts and walk across the room.” We suspected he might want that, so Sandy wiggled them off and handed me her shorts as he watched, then she slowly walked across and back. I wasn’t sure if he was watching her knees or her cute ass swaying as he squatted. Her toned gluts certainly put on a good show.

“I can’t see all the joints and how they move. I need you to remove your panties too so I can check for any hip joint rotation. Your husband may wait outside if this makes him uncomfortable.” Sandy blushed and looked at me. We said I always stayed with her in her exams — all of them. Here was an authority telling her to expose herself. She had ‘no choice’ and was secretly thrilled.

Obviously breathing faster, she hooked her thumbs in her panties and faced away from Dick as she pushed them down. As she chose to keep her legs straight until they were past her knees, her sweet ass came close to his face. I watched his eyes as he stared at her split cheeks and below them at her swelling, bare pussy. When closest to her bare ass, he sniffed deeply. I’d never seen a doctor do that before to my naked wife — though some were much more subtle. He put his hands on both hips and gently torqued them before turning her around.

Her landing strip and waxed labia still at eye level, he gently twisted her hips again. “OK. Walk slowly across the room again, but your shirt is blocking your hips, remove it.”

“But Dick, I have nothing under it. I’ll be completely naked.”

“Yes, I know. I need to see how your ankles, knees, and hips move as you flex and walk. You can’t hold anything up for the exam. Fold your arms behind your back. Do it or we’re done here.” She was too happy to comply after putting up some token resistance. She handed me her blouse and stood facing Dick until he told her to walk. Now I understood why the last patient was smiling.

Sandy walked slowly and proudly across the room for the stranger. As much as we enjoyed watching her bare ass swing, watching her naked pussy swing was at least as enjoyable. My dick was hard, so I checked and Dick’s dick was stiff too. He caught me looking, nodded to my dick and said, “A normal and expected reaction to watching a beautiful, naked woman.” Her tits and stiffening, rebounding nipples added to the fun.

“OK, Sandra. Take off the shoes and do it again slow and fast.” We watched closely. He then asked her to hop on the table and helped her. Though he took one leg at a time and pulled it to the side as far as it would go, his eyes were on her damp pussy most of the time. Even when he rotated her foot and felt her knee and hip, his eyes were on her swollen labia. He asked her to lie back and put both ankles on his shoulders as he sat. I moved behind him so I had the same clear view of my wife posing her pussy for this stranger. My cock surged.

With a hand on a knee, he moved her leg sideways, then back several times. He repeated it with a hand on her hip, then between her legs. Her pussy opened and closed for us. She was surely aware and she began smiling more; her clit began sneaking out from its sexy hood. Dick repeated the movements with the other leg. As I moved to his side, I saw his slacks tented. Already acknowledged, he didn’t hide it from me or Sandy.

“OK, Sandra. Now we get more intimate. Your muscle control is great, but I need to see how your legs react without voluntary control. I can hook you to a machine and zap 5000 volts down several nerves, or we can use a more pleasant test.” Her eyes bulged, we naturally chose the pleasant test. “Great. To get to involuntary control, I need to watch you climax. You can’t do it yourself since that requires voluntary control too. I will use digital stimulation and more if needed. Your husband may help. Are you good with that?” She slowly nodded.

“Do you have anything you especially enjoy — like oral or anal sex? Any particular fetish that gets you off quickly?” She nodded slowly. “OK. Pull your knees to your chest and wide apart.” That exposed her pink butt hole to us. He gently rubbed her round muscle and sniffed it. “Have you always been constipated? I see you are not bleached and still pink here.”He gently spread her cheeks and licked her rear hole. After savoring her taste he went back for more. After grabbing a lube from a drawer, he rubbed it across her rear hole. “You can relax with this. It’s an antibacterial and edible lube. I’m pushing my fingertip inside. Relax if you are enjoying this and want me to continue.”

Even I saw her relax and sigh. Dick pushed his finger deeper and I watched her star hole fall in, then push out as he pumped his finger in my wife’s ass. My cock demanded a tight squeeze. “Feel free to strip and jerk off as you watch me arouse your wife. You may want to put it in her mouth if she enjoys that.” Though I never heard of an Ortho exam like this, I think all of us were enjoying it. As I watched him open her pussy and insert a finger, then two, deep inside her, I did strip and began rubbing my stiff cock. He watched silently. After a long minute, he licked her pussy and they both moaned. Liking her flavor, he licked again and sucked his fingers. When his tongue warmed her clit, she squirmed and stiffened.
