Unexpected fun in the shop

Peter worked in a small ladies and men's clothing store, trade had been slow since the New Year and his boss had chosen stay at home and leave him to run the shop. About 11 am the door opened and a husband and wife came in, both looked to be late 40's, early 50's. She was a small blonde milf though not what you'd have called a hot wife. He was a tall, boring looking six footer and as it turned out looks were accurate! Having acknowledged the couple, Peter left them to browse for a while, both were trying different things on and putting them back and Peter decided they were probably just window shopping and not looking for anything in particular....how wrong can you be!
When her husband was looking at jackets at the far end of the showroom, the blonde approached Peter with a pair of trousers in her hand asking if he had them in her size, when he replied in the negative she shrugged and said no matter she'd try them any way to get an idea as to what they would have looked like and disappeared in to the changing room. A couple of minutes later she was back out with them on, walking straight over to Peter she stood in front of him, looked him in the eye and said I think they're a little too big don't you as she held the front of the trousers out and away from herself. Peter looked down, an automatic reaction, to see her panties on show for him. He took a second glance and began to colour up as she grinned at him, her thin bra not helping to hide her hard nipples which showed how turned on she was even through her t-shirt and then she was off back to the changing room without a second glance to her husband who was still at the far end of the shop. Shortly after that they thanked Peter and left.
About an hour later, the shop door opened and the blonde returned claiming she wanted to try the trousers again, grabbed them and disappeared behind the changing room curtain. Two minutes later she pushed her head round the curtain and called to Peter, asking if he could maybe help her for a second. He wandered over and she pulled back the curtain and took his arm pulling him behind the curtain and there she stood just in her bra and panties. Peter wasn't sure what to do, his youth not preparing him for such an encounter but he needn't have 'worried' as she took control. She kissed him hard on the mouth then pushed him to his knees, she knew what it was she wanted and was going to get it. Pulling her panties to one side she told him to eat her pussy and as he started she threw a leg over his shoulder and took hold of his hair, pulling his face into her and grinding her shaven pussy into his mouth. The blonde with no name began to tremble as Peter continued to work away with his tongue and with a grunt she came, pulling his hair as she gushed all over his young face, rubbing herself hard against him. As she came down from her orgasm, she appeared a little embarrassed, thanks I needed that she told him while he still knelt on the floor at her feet, pulling on her jeans and t-shirt, she bent down gripped his chin, gave him a long kiss on the mouth and was out of the changing room and gone, leaving Peter wondering what he was going to do with the hard on that was making a tent in his trousers, well he mused, that's one for the wank bank anyway, not a bad day at work after all :-)
