honestly dude dont be nervous. all you gotta do is go and do it as best you can. i hope no one has to tell you where everything goes and how to use it right? haha! no but for real just hit that pussy. dont worry about pleasuring just her that what i did my first time and i messed it all up. just hit it the way it feels good to you. you should also ask her likes and dislikes. hard and fast? nice and slow? it may be akward for you to talk about with her but if you do it will make your chances of getting laid by her again better
