[3huro] Kinju no Omocha (Bessatsu Comic Unreal Joutai Henka & Nikutai Kaizou Hen Vol. 2)

Arrogant busty warrior Daria and archer Sharu rule their adventuring party from the Guild, treating their shaman Kuruto as trash to be ordered around and insulted. When the bullied Kuruto gets his hands on a demonic spell book that can do whatever it wants with the human body, he shrinks his big-breasted companions into tiny, helpless dolls whose enormously swollen breasts and soft, pliable bodies are perfect for groping and teasing. Now the tables are turned as the once-proud heroines whimper and beg for forgiveness while their former underling toys with them relentlessly, savoring every humiliating moment of his sweet revenge and suggesting prostitution might be their only future.
