When shopping for a new pair of running tights,so went to the local sports shop ,picked out a pair and asked the girl if I could try them on,it was back in the day when the changing rooms wr just a little curtain,so in I went,closed the curtain (or so I thought) stripped off my bottoms,as usual I wasnt wearing any underwear,so I’m half naked looking in the mirror and I notice a gap in the curtain and the girl sales assistant is looking through the gap,she didn’t notice I had seen her,so I took my time trying the new running tights on,she was still looking,so I thought I’d have a bit of fun with her,so I pulled back the curtain,and asked if then has a bigger size in the running tight,she looked down at my bulge,smiled and said “I will have a look” so off she went so I took the running tights off,she came back,”I have a bigger size for you” so I opened the curtain a little more and she handed me the new pair,again she had a look,so tried them on,fitted well so I will have them,got dressed,went to the till and the sales girl was chatting to her friend about something,when they both saw me,both look led down at my bulge,and started giggling,bought the bottoms,so on my way out I said goodbye to the girl and her friend,she said “good bye,you have a big Willy” and started giggling again,so I said “thanks” and off I went! 😁
