SNOS-240 My beloved girlfriend was a shared pussy in the office, opening her legs to anyone—my boss, my colleagues, my juniors... But... I was so pathetic that I got an erection out of frustration. Murakami Yuuka

Yuka, whom I dated at the same workplace, was a girlfriend I was incredibly proud of, almost too good for me. She was beautiful, had a great figure, was cheerful, and got along with everyone... She was exceptionally popular with the men in the company. My annoying middle-aged boss, my close colleague, and the junior who had just joined. She got along well with everyone, and I respected her for that... But I had no idea what was behind her popularity. Yuka was sleeping with all of them like crazy. While I was swamped with work, she was having sex with the men at work so easily and happily. "You should resist more... Why are you having sex so happily..." I was frustrated. Frustrated. Sad. Painful. And yet... For some reason, my crotch was burning. "I'm sorry for cheating on you." "But why is your penis getting bigger?" Ah, why am I erect...?
