Party!

Kelly was excited about moving off campus Junior year, and found the perfect house but needed to find two roommates. The first was her best friend Jim, a party animal like herself, and the other responded to her flyer, a shy girl majoring in neuroscience named Becky. By the time Jim and Kelly were ready to host their first party, Becky had build a strange machine in the basement. After a few drinks, the two party-loving roommateswent downstairs and started to fool around with the invention. Sparks went flying, and soon enough Jim and Kelly found themselves in each other's bodies. Jim started to scuttle back upstairs, and Kelly demanded he come down to swap back.
"No way," Jim responded, "I'm going to have some fun! Come on! Look at your sexy legs! I'm so glad to try them out for a while..."
