Our Naughty Clit Technique

Between our being "naughty in the car" and actually starting to have sex, my girlfriend and I discovered a very satisfying technique to cum simultaneously without sex. She cums from clit stimulation very easily and she was actually the one who wanted to try this. It starts with a lot of kissing and foreplay just like any of our times together do. I love going down on her and she loves doing the same to me (see previous stories). When we're ready, she gets on top, but instead of me going inside she positions my member on her clit and slides up and down until we both come to a satisfying climax, usually together. We haven't done this in a while, but we just might when we get together later tonight after she gets off work.
