With the obvious: Ino!

"Um... you really want to let me pick?" Hinata asked Anko as they walked together through the streets of Konoha.

"Of course! I'm not just Master's Sex Genie, I'm also your loving and supportive harem sister!" Anko's copy asserted to Hinata, patting her back. "I might be pushing you a little outside of your comfort zone, but it's to help you get more and more comfortable with your role as my fellow harem ****!" Hinata blushed heavily, but paused to consider.

"Um..." she mused. "How about... Ino?" she suggested. That certainly made some sense to her. Sakura was already off with Naruto and the original Anko on that emergency mission to Suna, and Ino was the only other graduating Kunoichi from their year in their particular class. She also considered Ayame from the ramen stand, but shelved the idea.

"Ah, now there's a lovely lady I like!" Anko cheered, smacking Hinata's ass and making her yelp. "I once considered making her my personal apprentice!"

Hinata rubbed her ass where Anko has spanked it, blushing, but smiling slightly. "...what stopped you?" she asked.

"...there are only two people in the T and I department that can have a claim to being more scary than me," Anko admitted. "The first one is Ibiki, who you met in the Chunin Exams... The second is Inoichi, Ino's father. The guy can pull off mind rapes that would have Eldritch monstrosities run screaming in the other direction with the Yamanaka Clan techniques," Anko shivered. "He's head of my department for a reason. Long story short, I was scared of what he might do to me if I "corrupted" his daughter..."

"...but Ino's already going down a similar path as you," Hinata noted, knowing that Ino didn't exactly dress conservatively, used her looks to get her way, and had a scary streak of her own.

"Exactly! And that means Inoichi can't blame me for it anymore!" Anko smirked, clapping her hands together gleefully. "If he tries, I can just point out that she was already becoming another version of me without my influence... proof that being me is awesome~!"

"..." Hinata decided not to argue against that logic. She was too nice to do so, and it wasn't worth the brain cells anyway. "Right..."

"Anyway, let's get going and pay Ms. Yamanaka a visit!" Anko rubbed her hands together with glee. "To the flower shop!"
