Trolling For It

Troll Slayer (Monster Sex) - Anders Jarl Larsen,  A.J. Hamilton

 

Lovisa the Troll-Slayer has earned her reputation in an unusual manner, as you may have guessed. By coating herself with the musk of a female troll she's succeeded while others have failed, which also led to Lovisa discovering a not-unwelcome new pleasure in life. But before she indulges herself in it, she first seeks out a more traditional distraction with a sellsword named Marko.

More amusing than erotic, it's a bit of light entertainment and continues with the sequel Elf Lust.
