Give your partner's clit and labia a gentle oral sex massage by taking it all into your mouth, as you would a nipple, rolling, sucking and licking all around. Use different parts of your tongue, the tip, the centre etc. Use lots of saliva. Do this for quite some time. The longer the better. Like any sex, oral sex goes best with lots of build up, teasing and foreplay.

Once you have massaged enough, move onto oral sex directly on the clit. Remember everyone is different - this may not be pleasurable for her.
