The Haunted Vagina by Carlton Mellick III

It's difficult to love a woman whose vagina is a gateway to the world of the dead.

Steve is madly in love with his eccentric girlfriend, Stacy. Unfortunately, their sex life has been suffering as of late, because Steve is worried about the odd noises that have been coming from Stacy's pubic region. She says that her vagina is haunted. She doesn't think it's that big of a deal. Steve, on the other hand, completely disagrees.

When a living corpse climbs out of her during an awkward night of sex, Stacy learns that her vagina is actually a doorway to another world. She persuades Steve to climb inside of her to explore this strange new place. But once inside, Steve finds it difficult to return... especially once he meets an oddly attractive woman named Fig, who lives within the lonely haunted world between Stacy's legs.

"A very strange and surprisingly touching love story, despite the deliberately asinine premise. With subtle humor, surreal erotica, and some genuinely creepy moments, The Haunted Vagina is a completely unique reading experience."
