A handsome pick-up artist hit on Ririka-chan from a popular idol group and, after several failed attempts, finally succeeded in bringing her back to his place. Just when he thought he could have sex, he failed due to Ririka-chan's resistance to protect her chastity. The persistent pick-up artist tried again and again, and finally succeeded in having sex (which was secretly filmed). Ririka-chan started dating him and they had amateur sex on camera many times. Yet, Ririka-chan continued her idol career with a straight face. I wonder what will happen when this AV is released?
