Branded Azel 1 – Warrior anime girl is gangbanged by mushroom monsters

Niplheim no Karyuudo: Branded Azel
While fighting with a demon, Azel is captured and fucked silly.
After managing to escape she notices that a Crest engraved by the demon is left on her abdomen, a crest that causes insatiable sexual desire. I think she spends more time getting fucked by monsters than she does actually fighting the monster.
