START-590 A kind senior at my part-time job who turns flirtatious when drunk. As a virgin, I was left completely drained by intense affection and attention, and I was overwhelmed by the experience. Shibasaki Haru

Shibasaki, the gym’s training supervisor, is perfect on the job, but when she drinks, she transforms into a wildly uninhibited person. As a shy beginner, I’m completely swept up in her pace, and before I know it, both my heart and body are in her hands… Every act of temptation and jealousy is part of her plan to keep me all to herself…!? I can’t escape the affectionate, hands-on guidance of my senior, whose true feelings are impossible to read!
