Both! I haven't tried 69 in a very long time--I need to give that another go once we are reunited. It is challenging to give and receive at the same time, but I think I can do it better now that I'm older and more experienced. I have orgasmed from touching myself while giving him a very enthusiastic blowjob--that was fun! First time I've climaxed with a dick in my mouth...I was in heaven, and boy did he love watching me.
I actually had to concentrate on not losing myself so much that I might hurt him with my teeth at the moment of bliss. I succeeded.
