Sister Erune and the God of Love

A hungry tentacle monster encounters Sister Ernestine, a nun praying in the forest. Ernestine mistakes the creature for Alstella, the god of love she worships. Playing along, the monster claims it needs her life force to survive, prompting Ernestine to eagerly offer her body. She immensely enjoys their passionate sexual encounters and eventually asks the monster to live at the church so they can have sex every day. Ultimately, the church becomes famous as a holy site where a god manifested.
