MGMF-019 - Male slave to climax, sadistic sister's penile torture

The precious penis that was holding onto the strings of reason collapses miserably under the touch of a woman with overwhelming beauty and a sadistic aura. The humiliation of being trampled by boot heels in a secret space, but even that pain turns into pleasure! Bound and teased with lewd words, the agonizing denial before climax drives him insane. Her training dominates the brain more intensely than the body; the dizzying fantasy he's always dreamed of unfolds right here.
