Following on from the how to blow-job thread, which was very informative... Can anyone give me a bit of help with the woman in top position? Never ever got the hang of it!! Is it a siding back and forth movement or a lifting up and down? Sick to death of hearing how great it is - thought that I might have to buy a sexy dvd to look at how it os done - but sure that this is the place to get the handy household hints!
