DVEH-048 Will these underwear make you excited? A tall (170 cm) lingerie designer with a large backside (94 cm) and a well-endowed coworker do a fitting for panties. They jointly developed a beautifully alluring body with a very satisfying feel. Miokawa Haruka

Haruka, who works at a lingerie design company, is put in charge of developing underwear that supports women in becoming more confident. However, since she has no experience with men, it is a difficult challenge for her, and she struggles. Then, after a drunken Haruka catches the attention of a male employee, the project begins to move forward smoothly. Thinking that she needs to understand the appeal of underwear by exploring more risqué ideas, Haruka becomes absorbed in intimate relationships, and even her alluring figure is developed through the project as well.
