Maybe he was masturbating while driving. The truck driver I mean. He cold have been whacking it on nude photos from his phone and just going at it like a spider monkey, stopped in traffic, and just lubing up his junk and spanking it raw for everyone to see. Just sitting in traffic, no care in the world, pants down listening to J-Lo and staring in to his phone looking at cuckold videos and spanking it as hard as possible, as quickly as possible, thinking about after climax to go to IHOP for some fried eggs and grits before the next construction job and then whacking it again in the IHOP parking lot, just to finish off the job before going to hang dry wall and hide beers behind the wall and have another wank in the unfinished bathroom before getting back in the truck and speeding off to the next job but not before stopping at Wendy's drive-thru for a burger and more lube in the waiting line and then wanking it some more with a fresh bowl of chili, then after the next job stopping off at some place sophisticated like the local liquor store to get a bottle of gin so he can get wasted wanking it to that Mexican chick on Modern Family and then fall asleep on his air mattress and repeat the cycle again. Keep America Great.
