Have you ever wondered how to hide your cum if you live with parents and don't want them getting suspicious after seeing tissues in the garbage or cum on the towel! well I have the right tips for you, So, what do you have to do? simple, first off all remove the keycaps off of your keyboard, then get a pen, take the pen , using the pen, type in some porn (remember the keycaps are off that's why we're using a pen) and then start jerking off, and you hit the climax, just cum in your switches. That way the cum would be hidden and your switches would be lubricated (meaning they would be smoother and quieter), it's a win-win situation!
