He uses the oil

Suddenly, you feel a slickness against your ass, and the boy's fingers glide in with the help of the massage oil that you had been using on him. You yelp out upon entry, but don't look back as he begins to slowly glide two fingers in and out of your asshole.

Involuntarily, you begin moaning as you look at your throbbing dick below you, begging for release after everything that's happened today.

"Oh, fuck!" you scream in a high pitched tone as the boy hits your prostate with his fingertips. Just then, he removes his fingers, causing you to whimper.

You turn around, and the towel is removed, his massive teenage cock dripping precum and pointed straight upward. "OK, it's time for you to earn your paycheck...come on up," he demands.
