Looking for a story I know was here

I'm looking for a story I knew I read on this site a while ago. I don't know if it was removed or if I'm blind but I remember it well. It was about a lady who discovered that by using a large pillow and one of those vacuum suck and seal moving bags, she can use a small hole to slowly release the vacuum seal causing the pillow to expand, so she stuffs a sealed pillow under her dress and goes out to the mall for the thrill of it. The duct tape she used to keep the hole sealed wears off and so she rushes out of the mall, pillow still expanding, to get back home to save herself from embarrassment. I appreciate anything I can get cause I have looked and failed.
