I found a technique that my wife raelly seems to enjoy. We bought a glass dildo with a big head and a spiraled shaft. She lays on her back with her pussy facing me and her legs stradling mine.
I insert he dildo and start stroking her with it and then introduce and egg vibrator and work on her clit. When she comes it is intence and when I take out the dildo it is covered in her juices which is a turn on for me and she continues to have cum flowing out of her pussy.
