...Fuck me!”

Naruto only chuckled at his assistant’s antics. He grabbed her hair and pulled her into a kiss. He broken the kiss and looked into her eyes.

“Oh, fuck, we will.”

He caressed Shizune's cheek, then with a swift movement, he tore her kimono open, revealing her shoulders and breasts. Kunoichi moaned as her Hokage started caressing her breasts.

“Hmmm, I love sex after good particularly well done job, hmm.”

Naruto chuckled.

“You don't really need a reason to have sex, my kinky nee-chan.”

Uzumaki pushed her against the window. Shzinue's breasts pushed against the cold glass.

“Wait, someone will see us!” Shizune tried to push back, but Naruto pressed her against window.

“And doesn't that excite you?” A moan escaped her throat, when he pushed his finger into her soaked snatch. “That's what turns you on, isn't it? That someone might see you fucked, like one of slaves.” Shizune moaned again, when Naruto licked her earlobe.

Satisfied, that she stopped resisting (not that she meant it, Naruto knew her enough to say that her resistance was part of play), he hiked up her kimono, revealing her, shapely ass and bare pussy. Without a pause, Naruto penetrated her pussy, earning himself a lustful groan.

Chuckling to himself, he started moving. The feeling of her pussy squeezing his penis was heavenly.

Suddenly the feeling intensified. Hokage grunted as his assistant pussy's suction intensified, it's pressure and temperature rose.

'Did she just used chakra, to modulate her womb's stimulation?'

Shizune looked back at Naruto with seductively narrowed eyes. She smiled, then slowly licked her lips, in a way that gave Naruto a goosebumps.

'A challenge then? Fine!'

He could fold here pussy with his chakra (he had more than enough to overpower her), but this challenge had to be answered with... more ****!

He smirked... channelled Kyubi's chakra through his dick and pushed – once.

Shizune arched and she soundlessly screamed, when orgasm hit her. Then she collapsed on window breathing heavily. Finally she looked back on Naruto.

Her gaze filled with fear, that she might have bitten more than she could chew, and anticipation. After few seconds she seductively licked her lips, again.

Naruto didn't need more of invitation. He grabbed one of her legs under knee and rose it, presenting her bare pussy to anyone who might look.

Then he started moving.

With each of Naruto's movements, Shizune was hit with strong orgasm. They were so frequent, that they melted into one long orgasm with higher peaks of pleasure.

After eighteenth thrust/orgasm, Shizune's demeanour collapsed.

While drooling, she started babbling inconceivably, at one time stating that she's cumming, **** saying she's going insane at other asking for more, to fuck her stupid. The window she was pressing against has completely misted over, leaving only her flesh pressing against it, visible from other side.

After 20 minutes, Naruto finally climaxed, throwing Shizune into even a stronger orgasm. He allowed his half conscious assistant to slide down the window and sit in pool of her own pussy juices and drool.

At the sight of her smiling/drooling face he smiled.

'Challenger defeated!'
