Tease him

You step back into Bowser's embrace and place your hand on his cock. "Look... I am not trying to give you mixed signals..." you let your latex covered hand slide up and down the long bumpy shaft, spreading his precum along it's length. "By wearing this, I think I have already publicly accepted you right?"

He nods, but you aren't sure he is paying attention. You stop stroking him but don't move away, this brings his eyes back to your face. "Look, I think we both know where this is going, but that doesn't mean I am going to jump on your cock in front of a crowd. In fact I may not touch it again until you convince me." Putting action to your words you turn your back on him and take a step. Before he can start sulking again you turn so he can see you in profile and bring your hand to your mouth.

Slowly you lick the precum off your fingers. You use your tongue at first so he can see you licking each one. The act seems to work as you hear his breathing begin to pick up. To sell it you start to take them into your mouth. You suck on them, first one at a time but then two... three...

When you look over, his hand is on his cock. Nope... that is not what you want here... with a quick motion you slap it away. "No!"

"Buh... what?" Bowser seems deeply confused and you sigh before putting your hands on your hips.

"Are you really such a loser?"

“What?” Bowser says again his mouth hanging open.

“That should be my line, if you don’t have the balls to take what you fucking want, then I am going to get off on my own.” You would much rather the real thing but having him watch is pretty exciting on it's own. You decide to give him one more chance. You grab your bag and fish out a dildo and a condom before holding both up. "Choose!"

“Are you giving me permission to...” he stammers.

“Fuck no, I am ‘the’ princess of the Kingdom, and you are the KING that kidnapped me, what do you think should be doing?" Did you have to spell everything out for him? Why do the stupid ones have the biggest cocks?
