Grocery store jacking! First time writing a story

I had to share this story, cause I just can't get her out of my DIRTY mind! This happened last week at my local grocery store, I was shopping with a family member so I had to control myself, not that I would have done anything. I was in the pasta isle when this young lady was struggling to reach the spaghetti of the top shelf. Being the gentleman that I am, I offered to help and reached up and got it for her. And that is when I noticed the most beautiful ass I have ever seen in my life. She was a BBW but not to big just all the right curves in all the right places. She had on blue spandex yoga pants so tight you could see the outline of her g-string right through them.
This instantly gave me a stirring in my pants and had to do everything in my power to keep from getting fully aroused right then as I followed her around like a lost puppy dog and trying not to get noticed by her or my family member. Well unfortunately I could not shop all day and follow her around, and we went home.
Now most of my jacking sessions are to porn via computer or sometimes a magazine. But when I got home I ran to the bathroom and had one of the BEST jerking sessions I have had in a long time just from the memory of that sweet ass. I actually jerked myself to 3 awesome orgasms in like 15 minutes as to not get caught by my family member.
And now I am more then willing to run to the grocery store for anything just hoping to get a glimpse of that sweet ass one more time.
