I continued loading the conveyor (very slowly) on automatic pilot as I took in the details. I glanced at the name badge on her left breast: Lucy. Then back to her panties.

They were a grubby off-white colour, plain with no frills. They looked well-worn, even a little threadbare, worn many times with a few little holes here and there also showing their age. Clearly the supermarket didn't pay enough for a regular supply of new panties. My cock was now rock hard, to the point of discomfort.

As I continued slowly loading (making the most of her exposed gusset) Lucy turned her attention back to me, still smiling. She saw I was staring at something and followed my eyeline.

She gasped and her cheeks flushed red as she realised I was staring at her exposed knickers. She looked around to see if anybody else had noticed (of course they hadn't) and started lifting her bum off the stool to pull her skirt back down.

I held her gaze and raised my hand in a “stop” gesture and pulled a £5 note from my wallet, alternately looking straight into her blue eyes and down at her underwear. I palmed the £5 note onto the counter while it fairly quickly dawned on her what I wanted.

Still blushing furiously she surreptitiously tucked the money into a pocket and furtively looked around to make sure nobody else could see what she was doing.

Staring me straight in the eye Lucy raised the hem of her skirt even a little higher than it had been before and parted her legs again so that I had a perfect close up view of her grubby off-white panties while she turned her attention to the conveyor and passed my items through the checkout.

Eventually all the items were through. I went to the card machine and Lucy turned towards me, still showing her somewhat ragged panties in full view. As I dealt with the card payment I said “Very good Lucy. Let's do it again soon”.

As she gave me the receipt Lucy just stared into my eyes, her cheeks still blazing, but said nothing.

My cock remained rock hard as I drove home and walked into the house. My wife Anna was just home from work and still wearing her nurse's uniform. I could think of nothing but emptying my balls so took her by the hand to our bedroom and laid her on her back on the bed. I quickly pulled off my trousers and pants and Anna stared wide-eyed at my hard cock, standing up straight to my belly button and beyond.

I unceremoniously pushed up her uniform skirt, pulled her tights down and off and pulled her light blue knickers down until they were wrapped around her left ankle. She gasped and whimpered a little as I pushed all seven inches of my cock straight into her hairy fanny and started pumping hard. Then, just as I felt her twat getting moist around my cock and she really started gasping, I pushed even harder as I pictured Lucy's grubby panties and groaned as I pumped what felt like a gallon of warm semen up my wife's fanny.
