We know all too well your medical condition.  Mommy is the only one though that knows exactly how to do it and in a timely manner.  You are so healthy that you overproduce semen.  Your balls fill up so much that you need released within one hour or you have to be admitted to the hospital.  Mommy is an expert now because she has been relieving you since you started puberty.  It's 3 am and you come in my bedroom with an excruciating hard on that needs a handjob from mommy!  You have to wake me up but mommy is always happy to help you.  You show mommy your extra hard dick and balls that are so full they are about to explode.! Mommy tells you to take your pants down and let her work your throbbing cock....mommy even has glasses on to prepare for a huge load on mommy's face!!! ENJOY
