Dr Krystal is conducting some tests on a new Hormone enhancing drug. She locks two girls in a room and gets a male model to strip naked and play with himself the other side of a glass door. The drugged girls go crazy trying to get at the cock and force the door open. They jump on the guy, grabbing his cock and trying to sit on his face. Krystal is horrified but joins in and the three girls fight over the cock until he cums everywhere!
