You know, I heard of one gal who accomplished the trick by drilling a hole in the floor and putting the dildo in it. The thing is, she didn't close her blinds all the way and one night a peeping Tom caught her and crawled under the house and managed to substitute his real member for the dildo just at the right moment. Everything was going well until there was a knock at the gal's door and she jumped up and tried to kick the dildo under the bed . . . .
