...You had chosen the Crash Test Dummy symbol tattoo, which consisted of a circle that was colored yellow in the upper left section, black in the upper right, yellow in the lower right & black in the lower left. The reason you chose this one was in referential humor that this was the first time you were attempting something like this ever so it only seemed appropriate.
Turning on the faucet in your bathroom, you pull the plastic seal off the top of the temporary tattoo and place it underneath the running tap. You then remove it after the tattoo is coated in water and align it to the middle of your forehead, pressing it down on your skin. You wait a couple minutes, allowing the tattoo ample enough time to set, and then rip the white cardboard piece that the tattoo sat on off your forehead. The tattoo set perfectly, so much in fact, that it blends with your skin and doesn't crack when you furrow your brow at all. It's as if it was a real tattoo.
But that's not the only thing you notice. Suddenly you feel a wave of sexual eurphoria spread through you. You can't help but smile about this. The product actually does what it claimed to do. However, you're not sure how long the effects last so you need to make use of it immediately...
