Summary: Last time, the succubus Shiki went through a major power-up, and now she sets her sights on the exorcist apostle Reiko.
She is one of the Holy Twelve Apostles and former master of the fallen succubus Erika.

Shiki struggles against Reiko's overwhelming strength, and although Erika is nearly killed, they somehow manage to capture her.
However, even when transformed into a futanari and made to ejaculate like usual, Reiko remains completely unfazed.

During the 100-day period of ejaculation management, Reiko's futanari cock is tormented in various ways, but her expression doesn't change at all... She makes it through the first 50 days with a blank expression.

But, there's a secret behind her composed attitude...!
