A completely original work featuring 24-year-old graduate student Tachibana Haru. She attends a prestigious private university and was raised in a strict household, with little experience in relationships with men or satisfying sexual encounters. Wanting to truly experience pleasurable sex, she strongly desired to perform with a male actor and decided to appear in an adult video. This work vividly captures intense, detailed stimulation of her genital area, her swaying E-cup breasts, and her genuine first orgasm as she's overwhelmed by waves of pleasure. Her pure and sincere demeanor delivers a fresh emotional impact to viewers. No bonus footage is included.
