[Kouji] Turned into a Breast Milk Fountain by a Beautiful Vampire [Full Color]

A dark-haired girl with vampire fangs approaches a blonde beauty with a sinful proposition: a contest of endurance where the loser is forced into endless lactation and forbidden from touching themselves. As the blonde's resolve melts and her body swells, the story unfolds through shadowy mansions, bloody sheets, and a tragic backstory of lost loves — culminating in a final twist where demonic transformation and deep crimson consequences await. Temptation, obsession, and vampiric corruption intertwine in this full-color gothic tale of desire and surrender.
