After school, while working part-time at a J● convenience store, Konatsu was shocked to see an unexpected customer walk in—it was her homeroom teacher! The teacher had Konatsu straddle his upper body inside the store, then carefully massaged the groin area. He slid aside her paper panties, fondled her breasts, pressed his body tightly against hers, licked her nipples, and gave her a handjob. Overwhelmed by the intense service, Konatsu surrendered to her teacher's sticky, deep kisses as their forbidden passion escalated. They engaged in secret, immoral sex right inside the store, culminating in an unexpected creampie that revealed a side of her never seen at school. The student-teacher relationship took a hidden, illicit turn within the store walls.
