**This is a great custom clip request from a dear fan!** *Mommy has been training her son for sexual endurance! Let mom give you a nice blow job while I encourage my good boy!* Ok son, are you ready? It's time for your daily endurance training. Why don't you come here and let Mommy help you. That's it, drop your pants, lets get started! I'm going to give you a nice blowjob, you make sure you don't cum until I tell you! I want you to last 20 minutes or more this time, ok? Good boy! You're doing so well! Look how hard you are! The girls are going to love you! Aren't you lucky to have a Mom like me? Oh you're doing so well! Don't you love the way I encourage you while you hold back your orgasm for me? You're going to be able to last so long when we are done! mmm I love helping you and training you like this! It's good practice for me too! That's it, come on, you can last a little bit longer! When you're done I'll let you cum all over Mummy's face for last so long! You did it! You made it past 20 minutes!
