On your knees

You find yourself on your knees faster than you had expected, your hands resting on the top of your thighs as you watch Junior reach into his boxers and pull out his cock and balls. You can watch it harden in anticipation as the tip of it bobs in the air only an inch or two away from your nose.

Wow. You realize while looking at the owner's son's naked dick in front of your face that you're really doing this.

Fuck it. It's not like you've never sucked a sick before.

You spring into action, one hand on his balls and the other on his shaft as you take most of its length into your mouth. Junior is shocked, but he's hardly against it. One of his hands is wrapped up in your hair immediately, urging you deeper as you swallow his dick down your throat.

It's actually fun-- you never know when someone will come downstairs, and Junior is nice and responsive, grunting and stroking your hair as his dick disappears past your lips and down your throat over and over. You can hear the little gagging sounds coming from your own mouth, and you know it must be turning him on.
