Elixir: Love Potion #1.

A new potion is being tested; one that's guaranteed to produce instant erections and super stud marathon sex sessions. The inventor decides the best test group is a covey of sexy young studs, who are, of course extremely eager to try it out. The label should definitely have a warning that says “Warning, this product will cause you to have hours of sweaty, ass-pounding man-sex which may include 3-somes and daisy chains!”
