"My Boastful Girlfriend Worries Me..." My Aggressively Promiscuous Girlfriend Indiscriminately Tempts My Coworkers, Giving Me a Depressed Erection. Hiyori Yoshioka
"Surely not my girlfriend..." True to its title, this follows Hiyori, a beautiful, promiscuous girl who aggressively seduces every man around her boyfriend. She pins her boyfriend's boss against the wall for a blowjob, brings home a drunk coworker and immediately has sex without holding back. Each time she delivers lunch to the office, she sneaks slimy blowjob affairs inside the company, and keeps luring employees—after exchanging contacts—into her boyfriend's love nest for screaming, relentless sex. Her actions constantly involve the men surrounding her boyfriend, stirring new turmoil in their relationship. Her bold behavior and captivating beauty make her very presence the driving force of the story.
