Booty Call of Cthulhu (Paranormal, Tentacles, Dubious Consent Erotica)

Joanne Lagrasse is a newly graduated college student living the life. Well, if the life is sitting in your apartment all day trying to research monsters for a novel. The strange book her favorite professor gave her is full of ramblings by what must be a mad man, which makes for uneasy reading and a loner lifestyle. She pushes herself to go out to the beach, though she takes the tome with her. When she decides to not heed her professor's warning and reads a chant out loud, she finds herself faced with a giant monster and its lewd tentacles, each one eager to fill her holes.
