You have to take your vitamins! That's what helps you grow big, and strong. Don't you want to be big and strong for me? Your cum is full of lots of vitamins and minerals that are good for you, instead of keeping them trapped in your balls I want you to eat them all up for me. Stroke your cock exactly as I say until you have a nice, creamy pool of vitamins in your hand. Slurp it up, and swallow. Be a good boy for me.
