Get some legendary cock sucking

You: "Well you are the legendary sucker. So, start sucking."

She is turned on by your take-charge tone and gets to work fishing out your cock and when it springs up she catches the tip between her lips. She then licks the shaft to lubricate it with her drool before swallowing you down to the base. She alternates between moving her head back and forth so fast and licking your balls while deepthroating you. Just as she's impressed with how long you've held off on cumming, you hold her head down and release your load down her throat.

She is overjoyed to get your approval of her service in the form of your cum and does a thorough cleanup blowjob as you pull out.

Tsunade: "I trust it meet your expectations, master."

She has a look like she knows that was the best you ever had.
