Gag Reflex

"Well I think we should get the worst out of the way, lets start by testing out that throat of yours and seeing if your gag reflex is working right" She said with a smirk as he groaned and muttered "Now usually we'd do this differently, but since you've been so difficult lately we're going to use an experimental method" She lied, rumaging around the room and grabbing a cloth and a tube that had a very flared and phallic looking head.

"So, we're going to put this cloth over your eyes as studies have shown obscuring your vision improves test results, before slowly inserting this tube down your throat to check for abnormalities in your throat and gag reflex" She said, barely paying attention to her own words as she drank in his naked body, her cock twitching and practically begging to be unleashed on this naive idiot

For his part Naruto was in a minor crisis, due to the fact the tube looked almost exactly like a penis. If he didn't know any better he'd think she was planning on shoving a dildo down his throat, but she wouldn't do that, right? He banished those thoughts from his head and grabbed the offered blindfold, tying it over his eyes with shaking hands

Tsunade blinked in suprise, shocked he accepted that so easily. Knowing he wouldn't be able to see a thing, she unleashed her cock with a muffled sigh, admiring the thick, 12 inch log jutting from her hips, her giant balls practically churning with cum. It was actually an exact match for the dildo in her hand, which she quickly dropped on the desk

"Open up brat, this is going to be rough and feel weird but it has to be done" She said, her cock bobbing in front of his blushing face, his mouth slowly opening wide and his tounge rolling out, almost touching the tip of her cock
