They were laughing at each other as they had shed their clothes and they weren't even concerned with their naked bodies but were joking about them.
Tom had joked "Hey how much do those things weigh? they're pretty big."
Ashley said "oh it's not actually that uncomfortable, although it may be a pound a breast."
they joked and then saw a group gathering at the bumper cars, and went to the group.
Josh asked "Hey what's with the group?"
A naked guy said "Bumper cars, we're trying to get a full match and three short. wanna join?"
Ashley said "Sure, how about you guys?" All three had agreed and went to the bumper cars and learned some of the rules. Each bumper car has a transformation on them, and you transform everyone who is bumped and you are transformed by everyone who is bumped into you. If someone bumps into someone in contact with you you are transformed by the guy touching you. Other than that it's just a bumper car rink modeled after a race track. What happened?
