DMBJ-062 - Sweet Discipline: The Ideal Eros for M-type Men, Reiko Sawamura

I knew it was dangerous to have Reiko-sama in this series, but I watched it anyway. And... it was indeed dangerous. The plot is incredibly enviable: you get tormented continuously, only to be rewarded by Reiko-sama at the end. This work focuses heavily on discipline, so you get to be trained by the alluring Reiko-sama while she smiles at you. I can't take it.
