Tsunade: She's not just Konoha's princess - she's also something of a pillow princess. But you can usually compromise by letting her lie back in a comfy position while you sit on her face, that way she can focus all her physical efforts on pleasuring you. As long as she's getting plenty in return, she'll be nice and thorough and loves to listen to you beg for more.

Jiraiya: He puts the service in "servicing"! Will do it however you want and for as long as you want. It also gets him really horny so don't be surprised if he asks to turn it into a 69 so that he can get off to the experience of getting you off. If you're not in the mood though, he's just as happy to take care of it himself.

Orochimaru: Oh boy.
