his hips worked their way up and down in an ever-faster motion. And he moaned and cussed and told me how good I was and how much pleasure I was giving him in no uncertain words and in loud tones. When I felt him cum, I sat back into his lap, and he wrapped his arms around my chest, buried his face in the small of my back, thanked me again, and whispered something I didn’t quite get.

“What was that?” I asked.

“I told you we had other ways of exercising on the road,” he said in a louder voice.

"No, I mean that noise outside."

The door beside us was jerked open, and a voice boomed out, “We sure do like to exercise on the road, Dudes. Make some noise, why don’t ya? You had us over here with the horn honk.”

There stood three of the burliest men I’d ever seen, led by a bald, heavily muscled wrestler type with a mighty big grin.

“I want some of that myself,” the man mountain said, as he pulled me off Mac’s dick and hauled me down from the truck. Before either Mac or I could do or say anything, this guy, and a shorter, stockier guy, were carrying me away from the truck, while the third man was arguing with Mac and pushing his way into the cab. While I was being hauled away, I saw Mac turned sideways and on his back, his feet looking for purchase on the frame of the cab door, and a big, top-heavy trucker, his pants down around his knees, pushing himself into the cab opening and into Mac's ass as well.

“Just a minute,” the little guy said, arresting the movement of the bald guy who had me well under control. “I want to see this.”

We stood there in an entangled bunch, while Mac rose up and appeared in the door of the cab briefly, until the bigger guy backhanded him across the mouth and back down across the seats. The trucker was standing up on the running board. He kicked his pants off and tore his T-shirt up and over his massive shoulders. He was standing there just in his construction worker’s boots, and even I could see that he looked magnificent from behind. The big, bulky shoulders tapered down to a small waist, but his hips carried bulbous butt cheeks, and his thighs and calves were heavily muscled. His hands went into the cab and Mac’s jeans came out and were thrown onto the ground. Mac must have tried to crawl back across the seat, because his legs disappeared and one of the big guy’s knees went up onto the edge of the seat so that I could see big hairy balls and a pendulous, thick dong hanging down between his legs.

I heard a loud command and another heavy slap, and Mac’s legs and lower butt appeared at the cab door again. He was still on his back. The big guy forced Mac’s right leg through the truck door window and cranked the window up to hold his leg there and splayed his left leg up and between the truck cab side and a side bar on the other side of the door. He now had two free hands and Mac trapped in place. One hand got busy finger and fist-fucking Mac’s asshole and taking time out occasionally to push Mac back down on the seat, and the other
