Make yourself a sock cock.
Take a long sport sock and fill the toe end with something solid, a small bottle or can works well, then knot the open end a couple of times. Stuff the knots into your cunt to hold your sock cock in place. The knots should be big enough to be a really tight fit and hard to get in and out.
Now parade around in front of a mirror and enjoy your enormous cock. If its not a limit you could post a photo to show off your massive dick for all to laugh at.
