Tsunade is

"I'll be doing it this time brat" Tsunade said with a smirk. Naruto whined at the statement, knowing he won't be able to leave early. "Now get to your usual room and strip, it's a full body exam today" she said, smiling gleefully at his nervous expression and shifting slighty to conceal her bulge.

Naruto whined but matched towards the private examination room, knowing better than to argue. Once in he slipped out his clothes, hesitating at removing his boxers but eventually removing them as well.

He took a moment to gaze at himself in the mirror, flexing his muscles and admiring his slim but toned body. Never the tallest guy, he stood at roughly 5 foot 6, something he grumbled over.

Feeling a familar warmth overtake him, he looked down and moaned as he saw his dick harden, standing at 5 inches exactly but rather thick. Hearing footsteps, he sat down on the bed and covered his erection with a pillow just as Tsunade came in, raising an eyebrow at the sight of the pilloe concealing his lap.
