[Amuai Okashi Seisakusho (Tsukumaru, Nano)] Touzoku, Elf o Nusumu [Full Color]

A thief's reunion with his old ward is hijacked when a hungry slime possesses one of two beautiful elven sisters, stealing her voice, memories and soft, swelling curves to deceive her bound sibling and her former comrade. The possessed elf straddles her confused captor with heaving, milk-heavy breasts and a slick, trembling body, cooing with her sister's mouth while grinding down on his thick cock and taunting the helpless prisoner forced to watch. As purple slime coils tighter, pleasure swells into breast expansion and mind-melting ecstasy, until sisterly bonds dissolve into desperate yuri kisses, squirting climaxes and a sticky, corrupted rapture neither elf can escape.
