Sylvie and Jay have been friends for a long time. She is known for her brilliance and innovation and he is known as a slacker who loves to have a good time. Now facing being kicked out of college, Jay really needs to pass his finals and he turns to his genius friend for help. Instead of studying, the two come up with an unorthodox plan that involves Sylvie shrinking herself so that she can sneak in and feed Jay the correct answers. After a successful first outing, the two try it again only to find out that their actions have unforeseen consequences.

This is a shrinking tale (female and male) that consists of hourglass expansion, gentle insertion, MF intercourse and focused male expansion.
