If you suspect that your wife or girlfriend may be cheating on you, it’s actually pretty easy to catch them. You don’t have to hire a detective or anything. All you need is a semen detection kit. All you do is put a few drops of the secret formula #1 on her panties, blot the area with a little pad thingy, and put secret formula #2 on the pad. If it turns purple… Congratulations! It’s time to start dating again.
