Adventurer Rosary has finally managed to find her way out of a dangerous, horrible dungeon infested with monsters when she meets an unknown adventurer on her way home.

It turned out that he was looking for a ring, a cherished memory of his beloved, but he could not find it alone. Despite her fatigue, Rosary cannot leave the man in trouble and sets off again to the dungeon.

She walks cautiously into the depths, but suddenly she is taken by surprise by a parasitic monster that has taken possession of some corpse. Tired and exhausted, Rosary is unable to fight off the monster's relentless attack.

As her vision fades, she catches glimpses of memories she's never experienced before, which flash into her mind.

Memories filled with lewd and obscene experiences...

No, she couldn't commit such an abomination... Her body trembled, unable to break free....

Her body, now changed, driven by memories of lust and pleasure... Unable to escape... Or even resist.

Her virgin body is now as sensual and sensitive as the one that was fully "sexually trained”....

Can Rosary withstand the flood of sexual pleasure trying to overwhelm her body...?
