I know a lady that can rival the pornstar Cytherea.
When I'm DATY with her I keep a towel handy. When she says she's close I quickly place towel over the area and continue stimulation through the towel. She has to hold the towel in place and I have to roll out of the way as the towel will move and the pressure pushes through the towel. She lays on a pillow and multiple towels. She has hit me at several feet away if I didn't get out of the way, through a towel! She soaks through all the towels and the pillow to the bed. Alas, she is not a provider but one day I am going to have to measure the distance when she's uncovered.
