Shinji goes drinking at his best friend Daisuke's house, where there is also Arina, Daisuke's girlfriend. Shinji is very jealous of the couple's feelings when they continuously have intimate actions with each other. Because of his poor alcohol tolerance, Daisuke quickly got drunk and fell asleep. I don't know if it was accidental or intentional, but Arina's underwear was constantly exposed right in front of Shinji, causing his penis to quickly salute the flag. When she was sure Daisuke was asleep, Arina immediately approached Shinji, telling him how she had always felt unsatisfied with Daisuke's sexuality. She wanted Shinji to satisfy her long-standing sexual desires. Unable to resist Arina's deadly charm, Shinji was seduced by her and ejaculated over and over again right next to his best friend...
