Hitch-Hiker_英语成人笑话

there's a hitch-hiker waiting for a ride, and then a semi comes along, and the driver decides to pick him up. so after a couple of minutes of silence, the truck driver asks, "hey, wanna see a trick?"
"sure," replies the hitch-hiker. so the driver calls up a monkey from the back, smacks it, and it gives him a blowjob.
"hey, you want some of this action?" asks the driver, and the hitch-hiker replies, "sure, just don't smack me so hard."
