Whats supposed to happen here?

Me and my g/f were talking one day and we figured that it was time to take another step up in our relationship. So I did what I said I was going to do. She said that she wants to return the favor, but she says that she has never done it before. She...

said that she would definitly do it if she knew what she was doing. Problem is, I don't know either, I've never been given a hand job. So what is supposed to happen here?

Well it's pretty simple get comfortable start kissing each other and as her hands goes over your body and slowly makes it there just tell her to start stroking it gently. Using lotion helps with the sensation. Kissing as she strokes it is very sensual. I do hope you've both talked about where it can lead and knowing when to stop.

I don't mean to assume anything...but- well, if you're a typical guy, you've probably given yourself your own handjob before, correct? It's basically the same thing, just guiding another person to touch you in that way. If you haven't ever jacked off before- help her out a lot and let her know what feels good. My fiancee sometimes puts his hand over mine and will guide the strokes or how fast I should go, it helps him get what he wants and helps me know I'm doing it correctly. Oh, and if she's never done it before, her hand is probably going to get tired, so let her know you can take some breaks once in a while during the process till she gets the hang of it. Good luck.
