The Right Motivation

Two friends, Chad Rexx and Kai Carter, are studying together. However, Kai is struggling, and complains that he is the WORST at science. Chad says that Drake just needs the right motivation, and offers to help by quizzing him and providing an interesting reward - every time Kai gets an answer right, Chad will take off an article of clothing! The motivation works, and once Chad is fully naked, they take a break from studying to have sex.
