19-year-old Eri applied because she wanted to lose her virginity before turning 20. She feels uncomfortable talking to men, so on the day of filming, it took hours of gentle interaction before she could slowly start conversing. They began by hugging fully clothed, then moved to light kissing. Her tension gradually began to ease. Next, they gazed into each other's eyes with her pinned against the wall, sharing another kiss. After that, her breasts were fondled, followed by her first cunnilingus. As sensations slowly built, the penis was inserted, and despite enduring pain, she experienced her first sex and loss of virginity. Her nervous yet emotional first time vividly captures the transformation of her feelings amid tension and anxiety.
