Futanari Kunoichi Nine Tails 3: Deus
Description
Aina is under the influence of the aphrodisiac poison and Yaoi is at her wit's end: there's only so much sex a futanari fox girl can take before her stamina runs out. So after Aina goes into a rare refractory period, she subdues her and goes to raid the lair of Futaba, the mad scientist of the Nine Tails group, hoping to get the antidote for the poison. What awaits her there are the mad scientist's sex machines, as well as Futaba's personal futanari golem. Life of a futanari kunoichi sure is tough.
