Tiny Evil(2018)

Takeshi, a suicidal man who wishes to lose his virginity before he dies, draws a demonic circle in hopes of summoning a succubus to wring him dry. He successfully calls upon one named Miyu. However, she is also a virgin—completely inexperienced with her sole purpose. While Miyu's best efforts to please Takeshi to the point of killing him are not fully effective, perhaps the unity of these two virgins can help them realize their true destinies.
