My stepson is almost going to college, and he doesn't even know how to use a condom. The other day, I found him inflating one like a balloon! As a stepdad, it is my job to make sure he knows everything he needs to know about sex, so I taught him how to cover up his big, fat cock. He was such a good student and had such a fine dick that I let him practice on mine too. He was having some issues putting the condom on my penis, so I told him to use his mouth instead of his hands, and that worked perfectly. All that was left to do was teach him how to get a dick inside his ass, and I was ready for that lesson.
