blow job help?

[DrunkenStepGirl]

there's this guy i used to be really into, we messed around a bit, but no sex cause i had a boyfriend at the time (well, still do but thats a different story).
out of nowhere last week he texts me flirting then asking if he can come over. he even texted me saying how he never got to feel my warm wet pussy (omg), ...
i ask him why out of nowhere (it had been a little over a year since we did anything) and he told me he just was thinking of me and really wanted to fuck me, like it was something he should have done but didnt. so all of his talk had me excited and when he showed up (i promise i told him not to he was all over me right away. i tried to be a good girl and pushed him off a few times and resisted a little but when he pulled it out i couldnt help myself and had to go down on him.
when i told him when we were texting that i couldnt sleep with him (ive only had sex with one guy) he told me that he hoped maybe at least i would give him a blow job cause it was fucking bomb from what he remembered. i love that. i like to be the best oral a guy can remember. and i have a few decent tricks but was hoping you guys can help me.
he's going to call me again and im sure ill end up on my knees again too and want to know what i can do to blow him away. how to you guys like a girl to start sucking you off, any special tricks you can share, hot ways for him to finish. any tips would be appreciated.
who knows maybe ill go down on you someday and your advice will be worthwhile to you
thanks in advance
