"Don't stop, mom. I'm nearly there!" you tell her pushing her head back down. "the issue is next year. I will leave for college and might not be able to come back home more than once every semester."

"You're right son, with your high sex drive you won't be able to focus on your studies if you can only use your mom once every few months. If only you could find another girl that you love. I think the best way would be for your mom to follow you there to take care of you." he replies.

"Thanks, dad. You're the best. Of course she can come back to you once a month to help you out. " you offer gracefully.
