Front piggy-back

So three dudes are hanging out coming back from a party or something. They are about to walk up their apartment steps and they are laughing, joking, talking, etc. One guy is ahead of the other two and is like "hey guys hurry up" as he leaves them on the bottom of the stairs. They are talking and they talk about giving eachother a piggy back up the stairs. One is like "no! get on here" and the other says "hah no get on here!" and they eventually get around to doing saying "lets do a front piggy back!" By the time you hear this the 1st roommate comes back down and says "what the hell are you guys doing?" And they say "front piggy back" embarrassed. And then they say "but we never really decided who was carrying who... so..." and then the first roommate says "so it looks like you are just humping eachother" and then the camera shows their pelvis' and you can see them humping. lawl. fin.
