Masturbating at Walmart

So today I'm shopping for new bras and panties at Walmart. And it's been a few hours since I last masturbated, so I'm picking out some sexy bikini panties thongs and new bras. I have four thong panties in my hands 2 waist bikini panties and four bras. When I go to the changing room I wanted to masturbate so badly. There was an elderly lady by the changing rooms at work for Walmart and she asked me if I was trying the panties on also, and I said of course I am she got a little Wicked grin on her face and asked what I was wearing under my jeans I told her I'm wearing a thong. She really started to Grimm and told me to enjoy myself and then asked if I would model them for her, and I said for sure I would love to show you. so I slipped on a pair of thongs over the ones I'm wearing to keep them clean can I put the bra on a matching set just then she knocks at the door she goes it's all clear Nobody's around and I open the door wide open and she standing there with her eyes fixated on my cock cuz now it's hard. and I didn't notice it before she opened the door she had unbutton two buttons and I could see her bra. The bra is a lace see-through Style. then with all any warning she walked in the changing room and close the door and said that I needed help with my hard on. She got down on her knees pulled my panties off and start sucking on my cock. I reached down and I slid my hand on in her bra and pulled it up so I could feel her tits. The way she was crouched down her pants pulled down her ass she was wearing a beautiful g-string. I was almost ready to come right there and then but I pulled her off my cock and stood her up and kissed her so I could taste my cock and unbutton her jeans and slide my hand on her pants felt beautiful fully shave wet pussy she was looking in my eyes I slip my fingers into her wet clut and she started to cum. She's soaked her panties with her beautiful pussy juice I took my fingers and put them in her mouth and she like them clean she then got back down on her knees and finish sucking me off how I blew my load in her mouth and she swallowed every drop of it. she then got up took her panties off gave them to me and I put them in the bag that I was carrying and she took her bra off and gave me to keep it for a souvenir.
