Noroi no Yubiwa de Game Over

Adventurer Rozarie was finally able to escape the dangerous dungeon overrun with monsters, when she encountered another adventurer on her way home.
It would seem that they are searching for a ring, a cherished keepsake of their lover, but were having trouble finding it alone. Regardless of her fatigue, Rozarie is unable to leave the person in trouble be, and enters the dungeon once again.
She takes care in proceeding to her destination, but is caught off guard by a parasitic monster that has taken control of a corpse. Tired and weary Rozarie is unable to fight off the monsters relentless assault.
As her vision fades, she catches glimpses of memories that she has never experienced being planted in her mind.
Memories filled with lewd and indecent experiences...
No, she couldn't have done such filthy things...her body quaked, unable to escape...
Her body, now changed, ruled by memories of lust and pleasure... is unable run... Nor even to resist.
With her virgin body now as sensual and sensitive as one which has been fully "sexually trained"...
Will Rozarie be capable of enduring the torrent of sexual pleasure trying to sweep her away...?
