This is my personal sequel to the unfinished story in the Konoha Sex Diary anthology by Stixz Awesome, I do not own Naruto, or the original Konoha Sex Diary in any way.
Tsunade honestly couldn't believe sakura hadn't become some kind of zombie after 3 full years of constant edging. Not to say that Sakura hadn't almost completely lost her mind from the daily edging, although in a way she actually did. If it wasn't for the genjutsu then she no doubt wouldn't have made it.
But it worked, Tsunade had made the perfect sex slave that she just couldn't get enough of, completely obedient, and with a simple command became one of the stronges ninja of her generation, all thanks to her training. And for the past week, in preparation for the long awaited, possibly mind breaking, orgasm that would fully unlock Sakura's potential due to years of self control, Tsunade hadn't even performed the genjutsu that kept Sakura's incredibly depraved, desperate, and horny desires dormant. For the past 6 days and 23 hours, Sakura had been in a state of constant edging.
Tsunade had edged Sakura more than ever, if her now 9 inch dick wasn't balls deep in Tsunade's pussy, or buried down her throat, it was wrapped in what tsunade liked to call her milking machine. All of this while Sakura was on the pill Tsunade had developed that stopped her from going over the edge, it was much more effective than a simple cock ring or chastity cage. And to top it all off she had given Sakura a potion imported overseas that made her dick unbelievably sensitive, to the point where just a drop would be enough to bring any normal man to mind blowing orgasms.
"Well are you excited, my beautiful apprentice?" Tsunade asked the incoherent Sakura, "the edging pill should wear off in about a minute or two, isn't that exciting?"
After getting a groan that sounded suspiciously like the word cum as a response Tsunade continued, "I suppose congratulations are in order, even shizune couldn't get through more than a full year before she gave up." She continued, "but you're different aren't you Sakura? You may not have been given the title of genius or prodigy like you're teammates, but I can say without a doubt that you have the potential to surpass me. In fact you mig-"
Tsunade's speech was cut short as Sakura suddenly sat up straight, her eyes wide as she finally reached the point of no return. As much blood as possible rushed into her hypersensitive cock, as an orgasm befitting 3 years of edging ran through every nerve in her body. She silently writhed in the binds that tied her to the chair as her byakugou seal activated, and her eyes rolled into her skull. Tsunade timed 15 minutes and 42 seconds was how long Sakura had been cumming her brains out, load after load filling up the milking machine before even it couldn't hold all of her cum, and it started pooling around the bottom of her chair with no signs of stopping.
Even when she stopped ejaculating she was still experiencing constant jolts of pleasure and numerous dry orgasms that were driving her crazy. When her seal finally reverted back into a diamond on her forehead, Sakura had passed out, while her body was still in a constant state of semi orgasm.
Around the 10 minute mark Tsunade couldn't control herself anymore and had taken off the milking machine and forced as much of Sakura's still cumming cock down her throat, tasting the thing she'd been craving for 3 years. She hadn't taken into account the fact that the potion was still on her students dick, and found herself in a similar state of orgasm before she too passed out, with Sakura's cock still cumming down her throat
