VEC-459 Mother's Best Friend Yumi Sakurai

Even though he was a student taking entrance exams, he was unable to concentrate on his studies and was at a standstill. I immediately start thinking about lewd things and can't go back to studying until I pull out once. Manabu is troubled by these worldly desires when his mother's best friend Yumi comes to visit. Manabu is completely charmed by Yumi's seductive, adult charm, and puts aside his studies to indulge in pleasure, but Yumi comes to see what's going on.
