My Girlfriend's Life Was Ruined By Becoming a Magical Girl

I, an earnest honor student, was enjoying a happy, still-abstinent life with my girlfriend Yukina,
until one day, when monsters from another world attacked...
But the attack also brings with it legendary magical girl Airi, who defeats monsters with sex.
It seems Yukina too possesses the innate power to become a magical girl,
and while she feels dirty about the possible repercussions, she ultimately decides to take up the mantle.
And that was the beginning of the end of the two of us...
