You have one role in life. Cleaning Chastity's hairy armpits, polishing em clean. Run your tongue up and down, make sure you get every last drop of drippy, sweaty filth off those pits! Do a good job, you don't want to disappoint your mistress! If you show Chastity what a good little armpit slave you can be, just maybe she'll let you jerk your dick off in the corner.
