Give her balls a nice tongue bath

You start by licking her large balls like they were covered in ice cream, this seems to settle her attitude for a moment or so. You pop a ball into your mouth and start sucking and licking all around it before spitting it out and moving on to the next one, you feel a little dirty doing this, down on your knees stroking a large anonymous cock through a hole whilst giving her balls the best tonguing you can give. You are really kinda getting into it and you start to feel your own hardon pressing against your pants, you want to take a hand away and help yourself as well but you are just having too much fun. After over 5 minutes of this she starts to feel a little neglected on other parts of her cock and is quick to point it out "Oh you are naughty, that was nice but don't forget i got more parts that need a nice tongue like yours" You take the hint and get going on the rest of her cock you sloppily slurping away trying to give your best go at it still copying everything you have seen from pornos.

Sadly she has already been unintentionally edged for almost 10 minutes now so you don't have to suck for long, your lover starts to hump the wall in anticipation and you can clearly hear her grunting in pleasure before she pushes hard against the wall and stops moving and without warning your mouth is flooded with cum, you are taken by surprise and out of reaction you take your mouth off her cock spitting out the cum in your mouth and watch as she sends 3 streaks more of cum onto your face and clothes and the last few dribbles out her cock onto the floor. After you gather yourself you are kinda disappointed that you didn't swallow, you look back at the cock that has stopped producing semen but is still slightly bouncing up and down, the women is silent for only a moment before taking her cock out getting dressed and leaving before saying "Thanks baby, oh and quick tip, get to the point next time hon, maybe see you again, or feel perhaps" giggling at her own joke before leaving still talking on the phone, you stay on your knees for a minute longer to evaluate your situation, a little streak of cum in your hair and on your clothes you are amazed and super turned on at the fact she was on the phone the entire time you sucked her cock. It gave you a giddy little feeling inside, you wiped a bit of cum off your face and put it to your mouth hoping to properly taste her cum, there isn't much cum but it was enough to know she tasted a little sweet and you are ready for more.
