The boss moaned and blew his load after about 5 minutes, and his cock started to soften, but Chad redoubled his efforts. Obviously, he had been paying attention when he got head, or maybe he wasn't as straight as everyone thought.
Chad had no idea how long before they got where they were going, but he was intent on getting 3 loads out of the boss and winning his freedom. SPLOOGE! Two down one to go.
"Fuck, you're an eager beaver, Chad. I bet if I - oh, ah, kung fu grip tongue?" He pulled his hardening cock out and stepped away from Chad's head, "sorry, Chad, tough luck, you're not gonna get a third load outta me now. We should have arrived. He pounded on the metal wall between the cab and back of the with Chad's flattened rolled up body at his feet.
"When we stop?" Shouted the boss.
"20 minutes!" Came the muffled reply.
Chad looked up at the boss and waggled his tongue as if to say come here.
