As if to erase the past self that couldn't confess to the childhood friend who was the object of first love, 'Satsuki' attempts to transform into a woman by altering her body with female hormone injections. Serving the master's sexual desires as a female beast of burden is what sustains 'Satsuki.' The dream of becoming a girl and being embraced by the loved one has warped over time, becoming lewd and lascivious. 'Satsuki,' drowned in lust, reaches ecstasy without the master's permission. Punished for her licentiousness with whips on her ass, 'Satsuki' heats up from the pain. At the peak of intensity, a cock is rammed into her lips, and 'Satsuki' completes her transformation into a complete female beast of burden.
