Get a dishtowel (or any kind of small towel) and a latex glove (the thin kind surgeons use, which can be found in many drug stores or hardware stores). Cut a hole in one of the fingers of the glove. Place the glove at the end of the towel on the side edge, and roll up the towel – snug, but not tight. Stretch the opening of the glove around the towel to stabilize it, and put some sort of lube into it. Then thrust into it. To clean up, all you have to do is discard the glove – but be sure to have plenty of extras, because you will love it! Reader improvement: Add 10 or 20 rubber bands on the towel at various parts, especially the entrance of the opening. It makes it tighter and feels a lot better and more realistic.
