Gag me how your stepdad likes it!

Stepdad is on a business trip and his wife and I are home alone. I'm relaxing with a bit of tv when stepdad's wife calls me over. She's got her laptop on her knee and just discovered some strange website showing clips of gagged girls from the search history. I'm asked if I visited that website on her computer but I didn't so it must have been my stepdad who looked at this. His wife and I curiously study the website and its content. Girls are gagging themselves and getting gagged by others at a website called Selfgags. It feels pretty strange looking at this website with stepdaddy's wife but we actually become pretty interested in what we see. We didn't even know my stepdad was into this kinda stuff and my stepdad's wife has never tried anything like this before. So curious to know what it's like being gagged, she asks me if I would like to keep her quiet for a little while. I hesitate for a bit but I'm always down for some fun and so I accept her request.
