My girlfriend has just got back off of holiday and she wants to meet up next week; and she wants me to give her oral (which I'm completely fine with) but I don't know how to do this, as I have never done anything like this. I love her so much and she's gave me oral
Before and I want to return the favour but I have no idea how to, so any advice would
Be great, thanks.

Just like with any kind of sex, different people like different things during oral sex so we can't tell you what will feel best to your girlfriend. I think the best way to approach this is to talk with her about what feels good, try what she suggests or what sounds good to you, and then listen to the feedback she gives you.
