Daphne & Velma vs. Tentacles (Gumroad)

The Mystery, Inc. gang is on the trail of a mysterious priest who became obsessed with dark, occult rituals when they stumble upon something far worse than they could have imagined -- an eldritch beast out of nightmares, the tentacle beast Mok'Shoggoth! The fearsome elder god makes quick work of the gang before revealing his true intentions -- to violate the two beautiful survivors, Daphne & Velma, and impregnate them with his unholy offspring.
