I was naughty and made myself cum without master's permission, so while he was away he told me that I had to make myself cum while gagged so that I would drool all over my big tits and make a mess! He said I couldn't stop until I'd cum at least once, preferably twice, and had covered my tits in spit. Watch me drip and drool all over my tits because of the big ball gag I have to wear.
