Too late

Just as you're about to remove his cock from your mouth you feel his hand on you head as his balls tighten and he unloads his load into your throat.

"God Damn that was good!" He holds you on his cock till it deflates. After he removes it he puts it away and starts up the car to head to town.

You find yourself extremely horny as the car speeds down the road. You fight the urge to pleasure yourself but every bump in the road aggravates you more and more and the rubble strips he hits are pure ****.
