My gf and i did oral on each for the first time today, I did really good on her, and she went wild, and she was doing good on me, but I am a little too big for her mouth, good size for her pussy though, anyway we got interrupted, and she never got to finish me off. Regardless it felt great! I have had sex with her a lot before this, I was the first guy she has given oral too. Any tips on doing really good for next time?
