A lasting effect.

Tsunade folded her hands infront of her face and let out a bit of a sigh. She glared over Naruto for a moment causing the fear he was already feeling to increase twice fold. He could not get a read on what the Hokage was about to say but something told him it wouldn't be good. Tsunade stood up and walked over to the young ninja before her.

"That little potion of you had is quite interesting" She said in he authoritative tone. "it's effects are strong in the beginning however it's true power is it's second effect."

"S...second effect?" Naruto stuttered as the Hokage drew near. "What second effect?"

"It has a sort of hypnotic in it." She says keeping her tone. "It is triggered by endorphins that are released during sex. It imprints the victim on to the first person they see when triggered. Leaving the person imprinted the center of any al all desires and fantasies."

"Wait. If that was true then" But before Naruto could finish his statement Tsunae had dropped to her knees right before him.

"Yes. You are imprinted in my mind." Tsunade was now blushing as her gaze moved from Naruto's shocked face down his body. "I have had so many dreams about this since that night. Fulfilling any and all naughty thoughts a young man like you might have."

"This... I mean... you couldn't" Naurto was in shock. "This can not be real there is no way."

"Then let me prove it to you." With that Tsunade pulls open her top revealing her ample breasts. "Do you remember how these feel? When they were pressed around your hard dick? Let me remind you. And this time you can cum wheneveer you want."

With that Tsunade pulled down Naruto's pants revealing his hard dick. Moments later she was moving her breasts up and down his dick. She had waited so long for this and now she was enjoying every moment of it. And from the looks of it so was Naruto. Every time her breasts moved across his shaft it was like she needed him more and more. She knew what she had to do next. Before Naruto could say a word she had switched positions and was ready to take him into her mouth. Slowly at first but soon she was taking him fully.

"Damn... that feels good." Naruto moans as he grabs the back of Tsunade's head. "Keep that up and I'll cum in no time."

Hearing his comment Tsunade speeds up and brings him deeper down her throat. It isn't long before Naruto lets out a loud almost animalistic moan and cums. The second Tsunade tastes his cum her eyes roll into the back of her head and her body spasms in pure sexual bliss. She swallows down every drop before pulling away from Naruto with a loud wet pop.

"That was amazing" Tsunade panted her body still shaking. "It looks like i was right about other possible effects too."

"Other effects?" Naruto asks still trying to grasp the reality of what just happened.
