He decides to try something kinky.

Naruto then pulled Anko's head down, so she was in a position with her ass up, and cheek on the floor, before he took the Note again.

"Naruto Uzumaki will grow a second shaft for his cock above the first. It will disappear when he next cums."

He then moaned as he felt the area above his cock get hot, then grow outward, becoming a second dick attached to his body. He then walked around to get behind Anko, and knelt, lining his lower cock up with her pussy, and his upper one with her anus.

She shook her ass enticingly, unaware of the second dick as of yet. "So, which hole do you want? My pussy or my ass?" she asked, unaware of the change he had made.

He grinned and replied, "Yes," then pressed in before she could ask what she meant.

"Ah!? What the!?" she cried out, extremely turned on by having both holes penetrated simultaneously. "How are you doing that!?" she groaned as both cocks had gone halfway in.

"That's my secret," he teased her, giving another push until both of her homes were filled by him, then he began to fuck her with both dicks, making her squirm helplessly as she was both still tied up, and still wanted him completely.

"Oh yes, fuck me!" Anko cried, deciding she didn't care how he had two dicks in the face of the pleasure, and he grinned as he started to roughly fuck both of her holes.

He pounded into her for a bit, giving her ass several spanks as he went, making her moan out in ecstasy. "Yes, fuck me hard!" she cried out, glad she had soundproofing seals, else the neighbors would have driven her crazy with complaints long ago.

He then grabbed her hair, pulling her head back, and making her scream in joy at being used like this, her boobs now what supported her upper half, squashed to the floor.

He grunted and came from both dicks, filling up both of her holes. She laid there panting as Naruto's second cock pulled back into his body, and he pulled out, giving her a final spank, which she cooed to.
