A semi-model college student is a second virgin. Riona Hashiguchi is a current college student who took part in the beauty contest at her university, taking advantage of her model-like height and outstanding proportions, and won the runner-up prize. Contrary to her enviable beauty, she is a pure and innocent girl with little experience in that field, confessing, "I've only ever dated one man." So, in order to acquire the unique "sexiness" of an AV actress, she makes up her mind to expose her beautiful naked body in front of the camera, and every time her sensitive parts are touched, her embarrassment gradually turns into an addictive pleasure... This is the WAAP debut of a fresh and cute college student, with 3 large-volume scenes. 5 chapters in total.
