I didn't know much about happening bars, but just wanting stimulation, taking Mayuki (my girlfriend) was a mistake. I didn't know the true nature of Mayuki, who always looks at my face and approaches me, pure and loves me so much... no, maybe I didn't want to know. Sex had become monotonous and I couldn't be satisfied, so I pretended to invite her on a date and took Mayuki to a happening bar. I thought I could get excited by showing off my beautiful girlfriend with a great figure having sex with other men, but without my permission, the men came into the playroom and started having sex with Mayuki... isn't this a rule violation? It wasn't supposed to be like this... I don't want to see Mayuki having sex with other men. I apologized for deceiving Mayuki and said "Let's go home," but she said "I'm not going home," she's angry... why, let's go home. Then, a man in his 50s who said he was an AV actor came in and took Mayuki to the playroom... I don't want to see Mayuki being fucked by such an old man, she's never done anything like that with me...! Damn it, damn it, damn it, damn it, damn it!! It looked like something exploded inside Mayuki. She's a beautiful woman who rarely comes to happening bars, there's no way she wouldn't be popular. And Mayuki, who was fawned over and had her need for approval satisfied, realized that it was foolish to be attached to a useless man like me... You brought me here to see me like this, didn't you? This useless dick! All I could do was watch Mayuki playing with five men while crying... Even though I begged her, she stubbornly refused to have creampie, and I was made to do it by strangers... It's frustrating! I want to kill them! When my favorite woman is being slept with, I, I... was erect. My useless dick was erect...
