Baggie & Towel

This is kind of a combination of the Foo Foo and Baggie & Mattress techniques (see above and below). You will need one small towel, one sandwich baggie, one to ten rubber bands, and Vaseline (or some other lube). First, fold the towel in half so it's lying horizontally, and then place the baggie at the upper-left corner of the towel with its opening facing away from you. Next, roll up the towel. Use the rubber bands to hold the bag in place; you can use more rubber bands for a tighter "vagina." Next, take a bit of the lube and "finger" the "vagina" so it's slippery inside. Then lube up your penis. Finally, stick the artificial vagina between your mattress and box spring and pump away.
