Claimed by a Volcano God: A First-Time Sacrifice Story (Claimed by a God, #2) [EPUB ebook] 

He pulled me into the volcano and deflowered me rough!
 
I heard local lore about women appeasing the volcano, but I thought they were just stories until plumes of steam rose from the mountain. I gave myself to the volcano god, who sacrificed my purity in a rough, delicious ritual that had me screaming in pleasure and begging for him to erupt deep inside me.
An erotic short featuring a sexy volcano god, first time deflowering, exhibition, oral, creampie.
