After volunteering for a study of a new drug meant as the next generation version of Viagra, average guy Neil Jackson finds himself the cause of a growing problem. While the drug works, it does so beyond anyone’s expectations, and every time a woman has sex with Neil (or ingests his semen), they undergo a terrific growth spurt. Soon enough, his girlfriend is taller than he is, and has no problem getting taller, especially given the effects wear off. Fortunately, Neil doesn’t mind having a little fun. However, their fun is discovered, and they end up in the custody of the government, though not before they share the fun.
