They make her need to have her boobs touched.

Ino blinked, and then snatched Naruto's hands, pulling them towards her. "Hey, what are you doing?" he asked, beyt understood as she pressed his hands against her tits.

"Oh, that feels so much better... I just need your touch in my breasts..." she moaned. "...well, you gonna move them around?"

He grinned. Apparently, she couldn't bear not having his hands on her breasts right now... He began to run his hands over her tits with a smirk. "Oh yes, much better, my chest felt so bad without your touch..." she cooed. She then squealed in delight as he squeezed her breasts. "Ohh, so good..."

Naruto kept playing with her tits, leaning down to lick one of her nipples. This made her moan, and press her torso forward as he switched breasts to lick at.

She squirmed and smiled through biting her lip. "Oh yes, oh that's good, keep it up!" He then pulled his head back, so as to pinch and pull both of her nipples with his hands. "Nhh..." she moaned, before suddenly blinking and pulling away. Seemed the effects only lasted a couple of minutes, but it was definitely fun.

"Okay... That Sex Note has one perverted mind behind it..." Ino remarked.

"...duh, it's a Sex Note," Naruto deadpanned, before fishing out a petunia.
