VS-237 - Immoral Heart 2: Mayonaka no Tenshi-tachi

It lacks the fun of SM, so frankly, it's boring. I think the focus on the star-studded cast diluted the actual SM content. Since they had an SM club setting, they could have included some hardcore play from a professional dominatrix (maybe even a scene where Izumi watches and gets turned on). Overall, a frustrating work that leaves you unsatisfied.
