[ENG Ver.] Secret Mating Rituals of the Jungle Dwelling Dog-like Indigenous Men

Dr. Miyu is a passionate researcher who always puts her work before her own health and safety.
This time, she and her assistants have ventured deep into a foreign jungle to begin a new study.

During the expedition, she happens upon an injured young indigenous man.
Without knowing his name, Miyu calls him Datta and spends every waking moment caring for his wounds. With her help, his injury heals in no time.

In addition to his astounding regenerative ability, the man also began to learn and communicate in the language of his benefactors. Seeing unlimited potential in Datta, Miyu takes him into her care, and ends up living together with him for the purpose of furthering her research.

With Datta being so friendly, amiable, and passionate about learning, Miyu has totally let her guard down and is sharing the same tent with him, but...
Then one night, Datta abruptly kisses her. He declares that since Miyu saved his life, he wants to marry her. Then, without a condom, he pins her down and pushes himself inside.

Miyu assumed it was a one-off incident, just a mistake... but then it kept happening... night after night.
