Nuki Doki! Revolution 3

When half-naked shrine maiden Nonoa suddenly disappears, her childhood friend Yamato and an angel, Sera are thrown into a panic! Sera finds it strange that Filika, a devil, disappeared at exactly the same time. Equipping an angel’s halo and Nonoa’s panties, Yamato unlocks his hidden potential, and his penis grows in size. He spins it rapidly to achieve propelled flight, and he and Sera take off in hot pursuit of the naturally flight-capable Filika. Meanwhile, Filika abducts Monika and returns to her hidden base of operations. She then uses her sex slaves, once men but now creatures only of lust, to begin a questionable ritual. Monika milks her slaves for their semen. She repeatedly engages them in rough, nigh-beast-like sex and naturally succumbs to the overwhelming pleasure. She is repeatedly creampied, and as a result her abdomen swells from the sheer volume of semen inside her. Meanwhile, completely oblivious, Nonoa is taking a shower. Belly bulging, Filika sneaks up on Nonoa and uses her to complete the ritual.
