The Koopa loyalty reward (Patreon)

Boom Boom was rewarded for years of loyalty to the Koopa Kingdom, excited by the meat slamming, King Bowser himself will lend his body so that can be filled it with devotion!

(Cum+ video version available for the 10$ tier~)

The king's big body will cause the small top Boom Boom to go nuts and leave his nut inside Bowser! He will be milked by his gifted loyalty.
