I want you to follow my instructions carefully so I can give you the best orgasm ever.
We're going to play a game of endurance. Follow my every word and this will be so hot.
Get nice and lubed up and ready to go for me and we will start by stroking slowly. Now faster, now slow. STOP! Now just the tip, now the whole shaft. How are you holding up as you watch my hand and mouth on this cock I have in my hand?
Good job! (if you didn't cheat!)
