You use to be Captain Rex Starstud. A bold adventurer standing a proud 6'10 with a very strong physic. That changed when your ship crash landed on the planet of giant cow girls. At your height you only barely came up to their waists and they easily over powered you. You tried to resist them, but it was useless. You'd gotten used to the nightly routine of being given a bubble bath and then breastfed while still naked. It was the only time of day you were not in a diaper. The milk of the giant cow girls had the effect of slowly stealing your hard earned muscles and made you weak as a new born. It also shrunk your once very large manhood to a hairless cute nub and made your diapers a necessity. Your new name was Mommy's Little Precious and she was loved teasing you to almost finishing before diapering you for the night.
