Smother his Koopaling

With an only slightly exaggerated sigh of exasperation, you glide over to the spot between his legs on the carriage floor.

"Alllright, baby."

Kissing the crown of his cock, it's impossibly hard. The heat stays with your lips as you pucker up, stick out your tongue and drool lubricant, swaying your head to cover more of it. The stream of precum pulsing out helps, and finally satisfied at the level of wetness, you scoot closer, leaning your chest forward and swallowing his member in your cleavage. His tip easily goes through the top, and quite a ways further after that.

"Let's get this taken care of. Stay still."

Holding them together with your forearms, you press your breasts to his shaft and slide them up and down. When he grits and moans, you can't help but smirk and roll your eyes before delivering a series of cloyingly sweet kisses to the front of his cock that only make it twitch and spasm more.

"Come on big boy."

You plant another wet kiss.

"Cum for me."

Much sooner than you expect, Bowser erupts with white liquid, impossibly thick and all over your breasts and face. As he leans back and pants, you sigh again, planting an extra-extra-long kiss on his tip as a reward for following directions and looking up at him with half-lidded eyes.

"Good boy."

At that, his member suddenly springs back to life. You stare in shock for a few seconds as it pulses heat between your breasts.
