Sometimes the best lessons are not on the syllabus... College freshman Amber wakes up in someone else's room after a wild night of partying. With little memory of the night before - including how she wound up in that room or who she might have been with - she slips out and heads back to her dorm to get ready for the day, which includes taking an exam she's barely studied for. During the test, however, Amber is overcome by a strange, overpowering arousal. Does it have something to do with the huge bulge in her super-hot biology instructor's pants? Or could it be connected to weird changes Amber's body has been undergoing - changes that, overnight, have her straining the seams of her clothes? What exactly happened in that room last night... And with who? Story includes muscle growth, breast and butt expansion, and clothes destruction.
