It was the element of danger and unknown reaction if she woke that made it so much fun. It was either a slap and a "what are you doing you perv!" or a "ooh yeah, that's nice" etc. I once, but only once, managed a whole finger and tongue session with a hand shandy finish without waking her. Her face in the morning as she tried to work out why her bum felt a bit wet and why there was dried spunk everywhere was a picture. It's not so much fun with my current girlfriend as she loves it and just rapes me as soon as I start.
