We were driving along the highway, heading inland to visit my sister, when my boyfriend John asked me for a head job. He had his hand on my thigh, trying to work his way up.

“Come on,” he said. “I don’t ask you for much.”

“No way,” I said wriggling away from him. “What if we have an accident?”

“We won’t. Now come on,” he demanded.

“What if someone sees?”

“Who’s going to see you? I’m not stopping at any traffic lights if that’s what you’re worried about. Where in the country, for God’s sake.”

“What about truckies?” I asked.

“What about them?”

“They’ll see when you’re overtaking,” I insisted.

“What a quick flash of you covering my cock, big deal.”

He had a point, what would they see?

The thought of them perving on us had my pussy twitching. I wasn’t into exhibitionism, but now, thinking about a complete stranger watching us was turning me on. After all, they would only see the back of my head in his lap, it wasn’t like I was naked or anything.

“I’ll let you know when we’re going to pass one, okay baby?” He was putting on his sexy voice. The one I couldn’t resist, so I thought, yeah why not.

Undoing his zip, I laughed as his cock sprang out, erect and eager for a tonguing. I lapped at the knob, enjoying his moan as his hand caressed my hair. I pumped his shaft, my fingers grazing his balls as I licked lovingly.

I’d been doing this for some time and was shocked when I heard the loud tooting of a truck horn. I froze, his cock still in my mouth. His hand pushed my head back down.

“Oh God, baby, that was great. You should have seen the guy’s face,” he laughed as his cock grew in size. This was turning him on tremendously.
