You should get a partner for this one. First do Cleaveland Steamer on her. And make sure you chilli-dog afterwards. Important part is having a liquid poo and rubbing your whole baggage more than ever on her chest. If this way doesn't work, also try Cincinnati Bowtie. Right before you cum, start peeing and be sure you fill that tasty, yummy liquid in a glass. In the end, your Roofie will contain white, yellow and some brown. Some people also try slitting the chest with razors first, must do once at least in a life time. ;D
