Licking his ear, she beckons, "Cemetery. Midnight." 

~~~

Her bracelets uncoil like snakes, slithering up his nakedness before staking his wrists to the earth. Her pussy sucks in his cock with one gulp. Ravenous fucking begins. As their cries rouse the dead, magick coaxes his balls.

His dick explodes, feeding her spell. She squeezes her crystals while drenching his pelvis, her juices flowing onto the ground, feeding what lurks below. She chants, "Grant my wish, Marie Laveau!" 

Dirt shifts below, tickling his ass. He witnesses her breasts rise and her facial lines soften. His cock reawakens with her tightening pussy.
