[Kusayarou] Bride of Lamia [Full Color]

A hero ventures into an ancient labyrinth to seize the treasure guarded by a lamia no one has ever returned from, only to find the serpent has already claimed his brother's soul—and now she wants him as her bride. Sealed with a 'couple's contract kiss,' his body begins to betray him as the dark-skinned monster girl winds him tight in her massive tail and fucks him toward an ahegao-eyed surrender, his crotch burning as a slick new womb forms alongside the cock still aching hot between his legs. By the final page, resistance melts into heart-shaped devotion—two brides entwined in serpent coils, happily killing every intruder foolish enough to disturb their forever together.
