I've had some Sciatica pain just recently, it got so painful a couple of months ago I made a call to my local surgery. The lady on reception said the doctor would call me back to discuss.
Sure enough, within 20 minutes the phone rang and it was a lady doctor. She said her name was Abbie, I was expecting my grumpy old male doctor but apparently he'd retired.
I told her of my woes and she said come down for the last appointment of the day.

I was pleasantly surprised, she was in her early 30's, had a host of tattoos on her arms, red hair, great body and stood about 5'4" in height. I told her about the pain I was getting in my hip and shins. She asked if I could take my jeans off, so she could get an idea of where the pain was coming from.
I duly obliged and took my jeans off. I was wearing fairly small Y front style underpants.

I guess I'm more of a shower than a grower, make your own minds up from my pictures. My cock is almost 6" long when flaccid, stretching out to 8" when happy to see you.
As she touched my hip and shin, her head just a few inches away from my cock, he began to stir.
Luckily she finished her examination and I put my jeans back on quick sharp.

She discussed the pain and we chatted away quite nicely. It turned out that she had recently moved down from the north east of England. I promised to stop twirking, if this was the cause of the sciatica. She laughed and sent me packing with a prescription.

About a month later I was fucking my wife, she was laid on her side, with one leg at 90 degrees allowing access to her pussy. Just after I shot my load deep inside her I twisted my hips and was in agony again.
I gave it a few days and called the doctors again.
Once again, Doctor Abbie called me back. She asked how it happened and I said just after sex. She said "oh dear" and said come down later, again last appointment.

I duly arrived at the surgery and was called down to her room. There wasn't anyone in the reception area and I think she was the only doctor there.
Again she was wearing her scarlet trousers and top.
"So you twisted you hip? what position was your wife when you did this?"
I explained the dynamics of how it had happened and she said "OK, I just need to see where the pain is now".
I removed my jeans and this time had my boxer style underpants on.
Again she touched my thigh and ran her hand down my leg. As she did this I noticed that she had a couple of buttons undone and I could see her lacy black bra and sexy redhead freckles on her chest.
My cock started to stir again and was heading towards one of the leg holes. The head was almost poking out the bottom when she said "ok" and finished her inspection.

She then kicked off her shoes and unbuttoned her trousers. She let them slide down and she stepped over them.

She was wearing black stocking with a suspender belt, no knickers. As I struggling to take in what was happening she unbuttoned her top and removed it. Her lacy black bra was on the floor with her top in an instant.
She now had a red flush on her chest, nipples sticking out in excitement.
"I need you to show me how you fucked your wife". She went over to the first aid bed and lay down, on her side with one leg at 90 degrees. "Is this the position"? Oh yes I replied.
I could see her pussy slit was wet, juicy pink lips just waiting to be parted.

I took my T-shirt off and dropped my underpants, my cock by now standing to attention.

Usually I like to give plenty of oral prior to sliding my cock in. This situation was completely different and my cock just wanted to be buried in that juicy pussy.
I slid him in about three inches, she was tight. So a few in and outs, every time a bit deeper.
My God she has a tight pussy, it milked my cock like never before. As she gasped I buried him deep inside and shot my standard eight spurts.
As I withdrew the warm cum trickled out of her gaping pussy.
Good job they put paper towel on those beds.

And what happened next?
Well I've been seeing her on the quiet for almost three weeks now.
