Okay so this is basically an advanced version of the human centipede, and it's totally PC. In this scenario you'd have 249 other people with a ball sack. Everyone is in a line on all fours sucking the balls of the person in front of them. Since there are 250 people with 4 limbs contacting the ground, we've got a 1000 legged sucking machine ready to move in the choice direction of the leader. (who isn't sucking a ballsack) Have fun with this one guys.
Ho-ho man! Did you see the human millipede walking down 7th street today? Looked enticing
the women has a period on the manssoft (non-erect) penis. the man then takes his bloody stump and wiggles it all over the women's stomach until he gets hard.
my girlfriend Jill came over last night and I wasn't hard yet so we performed a rusty millipede until I was ready
