Tsunade's Shemale Shame

[No_1]

Plot:
Tsunade, strong, beautiful, idolized by women and lusted after by men worldwide, she is known as the most beautiful woman in the entire world, but there's a problem with that, she isn't. She isn't even a woman...

Tsunade is a shemale, and she is terribly ashamed of that fact, and the little control over herself that she has because of it. Yes, like most beings with a cock, Tsunade tends to think with her other head.

During her time as Hokage she's made missions for numerous kunoichi to pleasure her, and has used their bodies as toys for her own pleasure, but things change after she makes an agreement with the Hyuuga elders to have a night of fun with their heiress, Hinata.

There are two options from here:

A) A male individual discovers this and blackmails Tsunade into becoming his pleasure toy, locking her in chastity and using her body, while reigning Konoha by proxy.

or

B) On the night Hinata arrives there's a surprise, the reason Hinata's so shy is she is also a shemale, and she's hung far more impressively than Tsunade. Hinata dominates Tsunade and develops more of a RTN personality due to her family trying to whore her out like this, beginning to blackmail her like in option A.

Either way, Tsunade is dominated and turned into the blackmailer's personal pleasure toy, locked in chastity and used freely under threat of her secret being revealed.

Requirements:

No underage, snuff, vore, scat or similar. Also no violent BDSM, while BDSM is allowed, nothing that would cause permanent harm (though body modification such as piercings or tattoos are allowed in moderation).

Tsunade is not particularly well hung (average to small) nor is she a great lover

Shizune is aware of Tsunade's condition, when they were alone she would occasionally pleasure Tsunade, but was generally the one in control during all sexual situations and is unamused by her mentor's attempts to use her as a sexual outlet (which were often little more than begging)

Tsunade is extremely sensitive (something of a two pump chump), and can anally orgasm very easily.

When Tsunade's locked in chastity she's desperate to get out, begging and offering to do anything just for the chance to cum.

Tsunade's quite inexperienced being the reciever during sex and thus has her ass heavily stretched

Options:

Incest and beast are allowed

The blackmailer may whore out Tsunade to others for political points (for example, whoring her out to the Inuzuka to pleasure their hounds)
If option B is taken, Hinata is very well hung and instantly begins humiliating Tsunade over it, being at least twice Tsunade's size.

The blackmailer in A may be any male character or another shemale, but they have to be significantly better hung than Tsunade.

Tsunade is fucked in public places and is forced to keep quite to avoid being seen

Tsunade may be commanded to bring women for her blackmailer to use (like Tsunade did before), and will be forced to watch while her master has sex with them (if the blackmailer is a shemale they may have sex with men as well, but the men are always the reciever) with Tsunade being made to do 'cleanup'
